Abstract

Prior research has mainly focused on what makes professional development effective from the program design perspective. However, there is a lack of understanding about what teachers need for improvement in the context of educational reforms and curricular changes. This study used the pedagogical content knowledge framework to examine teachers’ needs for professional development situated in specific science topics. Data were drawn from a total of 118 science teachers who participated in a professional development program over 3 years. First, this study identified a list of common science topics that teachers needed to improve in life science, physics science, and earth science. Also, teachers perceived the needs to improve teaching of certain topics for different reasons: themselves, students, and curricular changes. Moreover, data analysis showed that teachers needed improvement in multiple areas of pedagogical content knowledge: learners, instructional strategies, curriculum, and assessment. In particular, inquiry teaching was one of the greatest challenges for most teachers.

Introduction
There is little argument that teachers hold the key for the success of educational
reforms. Research shows that teacher effectiveness is a strong predictor of student
academic achievement (Wright, Horn, & Sanders, 1997). The recognition that
teachers are at the heart of educational reforms led policy makers and national
standards to demand high-quality professional development (PD) opportunities for
teachers. To improve teacher quality, each year the US federal government, states,
and school districts invest billions of dollars in PD for inservice teachers.
Unfortunately, the results of PD efforts have been largely disappointing. Too often,
teachers find PD irrelevant to their work in classrooms and misaligned with their
needs for improvement (Borko, 2004; Rotherham, Mikuta, & Freeland, 2008).
Lieberman and Mace (2008) criticized that ‘‘Professional development, though well
intentioned, is often perceived by teachers as fragmented, disconnected, and
irrelevant to the real problems of classroom practice’’ (p. 226).
A fundamental problem of traditional PD is that it fails to address teachers’ needs
(Borko, 2004; Rotherham et al., 2008). Thus, researchers call for PD programs to be
responsive to teachers’ needs for improving their practice. For example, Rotherham
et al. (2008) urged that ‘‘To strengthen professional development, the federal
government should draw on examples of well-tailored professional development
programs based on teachers’ needs’’ (p. 248). Therefore, more research is needed to
understand the needs of science teachers for improvement.
To fill the gap, this study aimed to examine teachers’ needs for PD. The context
of this study was a PD program for science teachers. To clarify, teachers’ actual
experience in the PD, while undoubtedly important, was beyond the scope of this
study. To tailor our PD to teachers’ needs, we asked teachers to choose two science
topics in their teaching that they felt were in great need for improvement. Teachers
were also asked to identify specific areas they hoped to improve in the two units. It
should be noted that teachers are situated in an ecological teaching system and have
to navigate through multiple demands posed by the school, community, district,
state, and national requirements and policies (Zhao & Frank, 2003). Therefore, what
teachers perceive to need improvement may be a reflection of external requirements,
rather than their own internal needs. Nonetheless, teachers’ self-perceived needs can
still provide valuable insights into the priorities and challenges in science teaching,
considering the central role of teachers in the ecological teaching system (Zhao &
Frank, 2003). The following research questions guided this study.
1. What science topics were perceived to need improvement by K-12 inservice
science teachers and why?
2. What aspects of knowledge did inservice science teachers need to improve for
the selected science topics?
3. How did teachers’ needs vary depending on teacher backgrounds including
teaching experience, grade-level, and gender?

Hewson (2007) argued that there are two essential focal points for discussing PD for
science teachers: programs and teachers. On one hand, from the perspective of
program design, there is a growing body of literature on characteristics of effective (or
high quality) PD. On the other hand, from the focal point of teachers, a significant body
of literature has examined what teachers need to know and should be able to do in the
climate of educational reforms. In theory, it makes sense that these two lines of
research should go hand in hand—effective PD should teach teachers what they need
to know and help them deal with challenges arisen from practice. However, research
on effective PD is largely disconnected from research on teacher knowledge. We
argued that understanding of teacher knowledge provides a useful framework for
considering teachers’ needs for PD, which serves as a basis for designing effective PD.
The following section provides an overview of the two bodies of research.
Literature Review
What Makes PD Effective?
Recent research has yielded important insight on what makes PD effective. Garet,
Porter, Desimone, Birman, and Yoon (2001) analyzed survey data from a national
sample of 1027 math and science teachers who participated in the Eisenhower PD
Program. The researchers found three structural features that helped to set a positive
context for a PD activity to take place, including extended study time, collective
participation, and emphasis on reform-oriented activities (e.g., study group, mentor-
ing) rather than traditional activities (e.g., workshop). In addition, the authors
identified three core features of PD activities that could enhance teacher learning and
improve classroom practice, including focus on subject content knowledge, oppor-
tunities for active learning (e.g., observing other teachers or being observed), and
coherence with teachers’ other PD experiences and state and district standards.
Penuel, Fishman, Yamaguchi, and Gallagher (2007) examined the effectiveness of
characteristics of PD in fostering curriculum implementation using a sample of 454
science teacher participants. Their findings were largely consistent with what Garet
et al. found. In particular, this study highlighted the importance of coherence of PD,
defined as ‘‘teachers’ interpretations of how well aligned the PD activities are with
their own goals for learning and their goals for students’’ (p. 931). Among all the
variables studied using hierarchical linear modeling, coherence was the strongest
positive predictor for change in teacher knowledge and classroom practice. Coherence
was also found to have a positive impact on curriculum implementation. This study
provided strong evidence that PD should be responsive to teachers’ needs.
In addition, several large-scale studies on the Local Systemic Change (LSC)
through Teacher Enhancement Initiative shed some light on features in high-quality
PD (Banilower, Heck, & Weiss, 2007; Supovitz & Turner, 2000). The goal of LSC
was to improve teaching of science, mathematics, and technology through teacher
PD, with a focus on preparing teachers to implement designated exemplary
curriculum materials. These studies emphasized that effective PD should be
content-based, situated in classroom practice, and sustained over time.
Understanding Inservice Science Teachers’ Needs for473
123
Taken together, there is a broad consensus that effective PD should include the
following features: (1) informed by learning theories, (2) intensive, sustained and
ongoing learning, (3) focus on content and curriculum, (4) opportunities for rich and
active learning, (5) collaboration with other teachers, preferably from the same
school, (6) connected to teachers’ daily practice and their own learning goals, and
(7) aligned with local, state, and national standards and objectives (Banilower et al.,
2007; Borko, 2004; Borko, Jacobs, & Koellner, 2010; Garet et al., 2001; Loucks-
Horsley, Love, Stiles, Mundry, & Hewson, 2003; Penuel et al., 2007; Supovitz &
Turner, 2000).
The studies aforementioned made important contribution to the knowledge base
of teacher learning and pointed out critical principles for PD design. However, some
of these characteristics of high-quality PD are still too broadly defined to provide
detailed guidance for PD design. PD should be relevant to teachers’ needs and
coherent with their goals—a key feature of effective PD. Yet, we know little about
what those needs are.
In addition, research on characteristics of effective PD rarely connects explicitly
to research on teacher knowledge, although teacher learning is the common subject
in both areas of study. To understand teachers’ needs for PD, it is important to
analyze the task of teaching—what teachers need to know and should be able to do.
What do Teachers Need to Know and Be Able to Do?
A significant body of literature has examined what teachers need to know and
should be able to do in the context of educational reforms. In a review of research on
science teacher knowledge, Abell (2007) developed a model of teacher knowledge
that includes four types of knowledge base: subject content knowledge, pedagogical
knowledge, knowledge of context, and pedagogical content knowledge (PCK).
Subject content knowledge includes important facts, concepts, principles, theories,
and procedures that are interconnected in a science discipline. Much research has
shown that deep, structured, and accessible subject content knowledge is necessary
for effective science teaching (Kennedy, 1998). Indeed, a teacher cannot effectively
teach any topic without solid content understanding. Therefore, in this study, we
examined teachers’ needs for improving their own content understanding.
Pedagogical knowledge includes general knowledge of teaching and learning,
such as learning theories, instructional principles, and classroom management. An
important aspect of general pedagogical knowledge is classroom interaction and
organization (Morine-Dershimer & Kent, 1999). Knowledge of context represents
background knowledge of students, school, community, and district (Grossman,
1990), also referred to as classroom knowledge by Barnett and Hodson (2001),
which is ‘‘entirely situational and particular’’ and ‘‘rooted in the day-to-day
experience of particular educational situations’’ (Barnett & Hodson, 2001,
pp. 438–439). In this study, we did not focus on knowledge of context because
this type of contextual knowledge is most likely to be gained and accumulated from
a teacher’s daily interaction with students and local communities, rather than from
external PD.

Of particular importance is PCK, which is commonly believed as having the
greatest impact on teachers’ classroom practice (Gess-Newsome, 1999). Therefore,
this study adopted PCK as the theoretical framework to understand teachers’ needs
for professional development. The notion of PCK was first introduced by Shulman
(1986,1987). According to Shulman (1987), PCK ‘‘represents the blending of
content and pedagogy into an understanding of how particular topics, problems, or
issues are organized, represented, and adapted to diverse interests and abilities of
learners, and presented for instruction’’ (p. 8). In addition, a teacher needs to
understand what makes a specific topic difficult to learn and know how to build on
students’ prior knowledge. The hallmark of PCK is knowledge of teaching specific
topics to learners, which distinguishes a teacher from a content specialist or a
pedagogical generalist.
There is a growing consensus that PCK should be the focus of teacher PD
(Bausmith & Barry, 2011; Hashweh, 2013; Van Driel & Berry, 2012). However,
few PD programs seem to have focused on the topic-specific nature of teacher
knowledge. Yager (2005), for example, criticized that ‘‘One of the most serious
problems concerning professional development is the fact that schools often plan
general workshops with general leaders—all seemingly having little to do with
specific curriculum components or day-to-day teaching’’ (p. 99). Similarly, based on
a review of different models of teacher learning and PD, Hashweh (2013) found it
surprising that ‘‘Research on teacher learning and developmentstill views teacher
learning as a generic activity and neglects the domain or discipline specificity of
teacher learning and development’’ (p. 136).
In order to design PD that focuses on the development of topic-specific PCK, we
first need to understand teachers’ topic-specific needs for improvement. To fill the
gap, in this study we investigated K-12 science teachers’ needs for PD with respect
to specific science topics that they hoped to improve, rather than asking teachers
about their needs for improvement in general. We analyzed teachers’ needs
according to the PCK framework. Next, we clarify the specific aspects of PCK that
this study focused on, given various interpretations of this framework.
Since its introduction, the notion of PCK has stimulated a rich body of research in
teacher education and has been interpreted, refined, and extended by numerous
researchers (Loughran, Mulhall, & Berry, 2004; Magnusson, Krajcik, & Borko,
1999) (see Hashweh, 2013, for a more comprehensive review on the evolvement of
PCK conceptualization over the past 25 years since Shulman introduced the
concept). For example, Grossman (1990) added two additional categories to PCK,
namely knowledge and beliefs about purposes, and knowledge of curriculum
materials. Gudmundsdottir (1995) argued that the value-laden and narrative nature
of PCK should also be included in the notion. Magnusson et al. (1999) proposed a
PCK model that included five components, namely orientations toward science
teaching, knowledge of science curriculum, knowledge of students’ understanding
of science, knowledge of assessment, and knowledge of instructional strategies for
teaching science. The authors argued that ‘‘Effective teachers need to develop
knowledge with respect to all of the aspects of PCK, and with respect to all of the
topics they teach’’ (p. 115). The model by Magnusson et al. was a broader
conceptualization of PCK than its original focus on topic-specific knowledge.
Understanding Inservice Science Teachers’ Needs for475
123
Lee and Luft (2008) analyzed nine different conceptualizations of PCK models.
Despite some variances in the categories of knowledge included in the different
PCK models, most models agree that PCK involves (1) knowledge of represen-
tations and instructional strategies for teaching specific science topics, (2)
knowledge of students, including students’ prior knowledge, misconception, and
ways to connect science to students’ real-world experience, (3) knowledge of
science curriculum for particular grade levels and science topics, and (4) knowledge
of assessment, including what to assess and how to assess. These aspects of teacher
knowledge provide a useful framework to consider what teachers need to learn, and
in turn what responsive PD should offer. Therefore, this study examined teachers’
needs for professional development in line with these four aspects of PCK
(instructional strategy, students, curriculum, and assessment).
In addition, the work of teaching is further complicated by the national reform
initiatives. Prior research has documented that teachers had great difficulty
implementing inquiry-based science teaching as demanded by the national standards
(Germann & Aram, 1996; Martens, 1992), considering that many teachers did not
experience inquiry-based learning themselves as students and lacked the knowledge,
skills, and beliefs needed to teach science as inquiry. Now more than a decade has
passed since the publication of reform documents (American Association for the
Advancement of Science, 1993; National Research Council, 1996). Great efforts
have been made in both teacher preparation and PD programs to prepare teachers for
inquiry-based teaching (Crawford, 2007; Lee, Hart, Cuevas, & Enders, 2004;
Schneider, Krajcik, & Blumenfeld, 2005). It is unclear where teachers stand now in
their needs for improving their ability to teach science as inquiry. Accordingly, this
study examined teachers’ perceived needs for improving inquiry-based science
teaching, a critical instructional strategy for science education.
Teachers’ needs for improvement may be associated with their teaching
experience, the grade level they teach, and their gender (Davis, Petish, & Smithey,
2006; Lumpe, Czerniak, Haney, & Beltyukova, 2012). For example, beginning
teachers may have a stronger need for improving their PCK than more experienced
teachers (Davis et al., 2006). Elementary school teachers tend to view teaching as
‘activities that work’’ (Appleton, 2006). Such a view may affect their perceived
needs for improvement. They may also benefit more from PD in improving their
science content knowledge than secondary teachers (Shin et al., 2010). In addition,
prior study found that male teachers held a more positive belief about science
teaching than female teachers (Lumpe et al., 2012). Therefore, we were interested in
whether teachers’ needs varied depending on teacher backgrounds such as teaching
experience, grade level, and gender.

improvement, revolving around the critical aspects of what teachers need to know
and do as described in the literature. Prior research suggested that self-report
surveys provide a low-cost and relatively accurate portrait of teacher belief and
practice (Ross, McDougall, Hogaboam-Gray, & LeSage, 2003). Survey methods
have been widely used in research that focused on teachers, such as teachers’
perceptions of job satisfaction (Liu & Meyer, 2005), self-efficacy as teachers
(Bleicher, 2004), technology integration in classrooms (Proctor & Marks, 2013),
and standards-based classroom practice (Ross et al., 2003).
Limitations of the Study
Before we describe the details of participants, data sources, and analysis, several
limitations of this study should be noted. First, the teachers in this study were self-
selected for participating in the PD. This group of teachers may be more motivated
to improve their practice than other teachers. Second, this study reflected teachers’
self-reported needs for improvement, which may be different from their actual
needs. For example, teachers might believe they had stronger science content
knowledge than they actually did. Third, the findings of this study were based on
teachers’ survey responses only, without triangulation using data from multiple
sources and multiple methods such as interviews with teachers or PD facilitators.
Finally, the sample size of this study was relatively small. These limitations may
affect the generalizability of the findings of this study.
Participants
This study was situated in a PD program hosted by a science education division at a
large Midwestern university in the USA. We recruited teachers for the PD in a
variety of ways. We mailed the program description brochures and application
materials to local schools and distributed them at the school district centers and
local science education conferences. In addition, the previous PD participants also
helped to recruit peers in their school. Teachers who applied before the deadline
were all enrolled to the PD. Participation was voluntary. Participants received a
small amount of stipend and continuing education credits as compensations for their
effort in the PD.
Participants in this study included a total of 118 K-12 inservice science teachers
who voluntarily participated in our PD program over 3 years. One PD cycle,
including a 2-week summer workshop and a school-year teacher research project,
was completed in 1 year. Some teachers chose to participate again to improve
themselves as teachers, as they worked on different content and pedagogical issues
in another year. Among the 118 teachers (96 females and 22 males), 84 teachers
participated in the project for 1 year, 22 teachers for 2 years, and 12 teachers for
3 years, which resulted in 164 participants over 3 years. Because this study did not
focus on the impact of the PD, we treated each participation by the same teacher
separately. The teachers were divided into three groups according to years of
teaching experience: beginning teachers with 0–3 years of teaching experience;
established teachers with 4–10 years of experience, and veteran teachers who had

123
more than 10 years of experience. Also, 62 teachers taught science at the middle
and high school levels, and 102 teachers taught science as part of their load at an
elementary school. Table 1describes the teachers’ backgrounds.
Data Sources
The PD took place in the summer and the following school year. Teachers submitted
their application for the PD from February to March prior to a PD cycle. By the time
Cohort 3 teachers applied for the PD, the state implemented a new curriculum
standard called the Grade Level Content Expectations (GLCEs), which has now
been replaced by the Common Core State Standards.
In the application form, the teachers were asked to select two science unit topics
from their teaching, one as the first choice and the other as the second choice, to
improve in the PD. The teachers were asked to rate to what extent they thought the
selected topics needed improvement in nine aspects on a 5-point Likert scale, with 1
indicating ‘‘needs no development’’ and 5 indicating ‘‘needs a lot of development.’
The nine aspects measured content knowledge (CK), pedagogical knowledge (PK),
and PCK, including: (1) my own understanding of big ideas in the subject (CK); (2)
my interactions with my students (PK); (3) teaching this unit with inquiry or
scientific reasoning (PCK: Strategy); (4) building concepts through a series of
activities (PCK: Strategy); (5) my students’ grasp of big ideas in the subject (PCK:
Learner); (6) addressing students’ misconceptions (PCK: Learner); (7) relating unit
content to students’ lives (PCK: Learner); (8) developing effective assessments
(PCK: Assessment); and (9) finding good resource materials on the Internet (PCK:
Curriculum).

In addition to the rating scale, for each unit topic, the teachers were asked two
open-ended questions: (1) Why have you chosen this unit topic for improvement?
and (2) What would you most like to improve? Because teacher responses to these
questions were situated in the specific topics that they chose, we considered the
areas for which the teachers perceived the needs for improvement to be different
aspects of PCK.
Data Analysis
We analyzed the teachers’ ratings and provided descriptive statistics on teachers’
needs for improvement in the nine areas. We used one-way analysis of variance
(ANOVA) and ttests to examine whether teachers’ needs in their first-choice unit
were related to their teaching experience, grade level, and gender.
All teachers’ open-ended responses were entered into a spreadsheet and
organized by cohorts and units. Analysis of these responses was an iterative
process guided by the grounded theory approach (Glaser & Strauss, 1967). Through
repeated readings of these responses, the first author developed and refined a coding
scheme to categorize teachers’ responses based on the PCK framework. The unit of
analysis was defined to be a thematic unit in the responses that represented a single
idea. This definition was common in content analysis research (Rourke & Anderson,
2004; Strijbos, Martens, Prins, & Jochems, 2006). Teachers might specify one or
more areas they wanted to improve for their selected topic in their responses. For
example, a high school teacher chose to work on a unit called ‘‘organizational living
things.’’ Her response to ‘‘What would you most like to improve?’’ was ‘‘How to
teach this through inquiry? How to make this relevant to the students?’’ This
response was coded as ‘‘PCK: Learner: Relevance’’ and ‘‘PCK: Strategy: Inquiry,
PBL.’’ The coding scheme was revised in the iterative coding process. For example,
at first, inquiry-based learning and problem-based learning (PBL) were considered
separate categories under PCK: Strategy. However, it turned out that many teachers
did not differentiate the two strategies as they often put them together in their
responses. Therefore, it seemed more reasonable to combine the two strategies in
one category. Once the coding scheme became stable after numerous revisions, the
first author used about 10 % of the data to train another researcher who was not
involved in developing the coding scheme. Two researchers coded about 40 % of
the data independently, and the inter-rater reliability was 91 %. Disagreement was
resolved through discussion. The first author coded the remaining data. Table 2
presents the coding scheme for teachers’ open-ended responses.

these topics were presented according to science areas (life science, physics science,
and earth science) and grade levels.
Specifically, in life science, ecosystems, plants and animals, and human body
were some common topics across grade levels. In addition, in Grades K-2, five
senses and life cycles were common science topics for improvement. In secondary
grades, cells, genetics and heredity, and bacteria were common topics. In physics,
force and motion was the most common topic across grade levels. In addition,
matter and energy and light and shadow were also common topics that the teachers
selected for improvement in all grade levels. In earth science, rocks and minerals,
weather, solar system, and the changing Earth were common topics mentioned by
the teachers across grade levels.

The number in superscript next to the topic represents the total number of teachers who selected the topic
482 M. Zhang et al.

There were four major reasons that the teachers explained when asked why
they chose certain unit topic for improvement. First, about 23 % of teachers
reported that the selected topic was their weak area due to a lack of content
knowledge, training, or interest. It was not uncommon that teachers had to teach
outside of their field. Examples of the teachers’ responses were as follows: ‘‘This
is an area [force and motion] that I know the least about. I would like to capture
students’ attention in this area;’’ ‘‘I feel this is an area [solar system] in which I do
not have as much background knowledge in. Most of my undergraduate work was
focused on the life sciences,’’ and ‘‘Being a biologist, I am not as interested in this
area of study [weather]. I need to build my interest in order to inspire the interest
of my students.’
Second, the teachers selected a science topic to work on because the topic was
too difficult for students to learn, or because it was an important topic. About
10 % of teachers indicated that their selected topic was too complicated and
abstract, which cannot be seen and students tended to have misconceptions.
Examples included: ‘‘I have chosen this unit [ecosystems] because many of my
students have a difficult time placing animals in the correct [habitat], thus making
it hard for them to make correct choices when making a food chain.’’ ‘‘Both of
these units [weather or rocks and minerals] are conceptually difficult for 11- to
12-year-old students. Students love the laboratories but don’t see the connection
with the concepts,’’ and ‘‘I would like to improve our unit on protists because they
are confusing to the students and easy to get mixed up.’’ In addition, about 5 % of
teachers indicated that they selected a topic because it was important or appealing
to students, for example, ‘‘Kindergarten children have high interest in this topic
[magnets],’’ and ‘‘I chose this topic because the advanced rock cycle is a major
concept in the new HSCE [High School Content Expectations] for earth science. It
is also related to many other topics such as plate tectonics and the formation of
geologic features.’
Third, the most common reason was that the teachers hoped to refine an existing
unit to engage students and improve understanding. About 38 % of the teachers’
explanations fell into this category, for example, ‘‘I have chosen this unit topic
[energy and its transformations] as I don’t feel I necessarily give students good
concrete examples of everyday energy changes,’’ and ‘‘I’ve been teaching it
[ecology] the same way for so long; I want new ideas for investigations.’’ In
particular, many teachers mentioned that they wanted to improve the unit by using
inquiry-based or problem-based approach, for example, ‘‘I want the genetics unit in
my biology class to be more hands-on and inquiry-based.’’
Finally, 24 % of teachers, most from the last cohort, reported that they chose a
topic because it was a new unit that they needed to develop to align with the new
GLCEs that were implemented in the state during that year. The teachers often
mentioned that they had to start from scratch and asked for help, for example, ‘‘We
have new K-level GLCEs for this area and I don’t know where to begin!’’ and ‘‘A
big section of the GLCEs focus on this [force and motion] and I do not have a lot of
knowledge about this information.’

What Aspects of Knowledge did Inservice Science Teachers Need
to Improve for the Selected Science Topics?
Analysis of Teachers’ Ratings
The descriptive statistics for teachers’ needs for improvement based on their ratings
are presented in Table 4. First, teaching a unit with inquiry or scientific reasoning
was the most needed area for improvement for the teachers. For both units, there
were about 80 % of teachers who rated 4 or 5 on the 5-point Likert scale, indicating
that most teachers believed that they needed substantial improvement in this area.
The other three areas that the teachers identified as needing significant
improvement were fostering conceptual understanding, building concepts through
activities, and developing effective assessment. In addition, over half of the teachers
reported that they needed considerable improvement in addressing students’
misconceptions, finding resources on the Internet, and connecting unit content to
students’ lives.
On the other hand, the teachers were confident in their interactions with students
and they rarely mentioned their needs for improvement in this aspect in their open-

ended responses. The teachers were also relatively confident in their own
understanding of big ideas in the subject, indicated by the low mean scores of
3.07 and 2.97 in the two unit choices, respectively, which were the second lowest
rating in both units.
Overall, the teachers’ needs for improvement in different areas were fairly
consistent in the first-choice unit and the second-choice unit. Paired sample ttests
found none of the mean differences between the two units in the same area were
statistically different.
Analysis of Teachers’ Open-Ended Responses
When asked what they would most like to improve in the two unit topics they
selected, the teachers indicated their needs for improving their content knowledge
and PCK in four aspects: learners, instructional strategies, curriculum, and
assessment. Table 5presents the frequency count and percentage of teachers who
indicated their needs for improvement in each aspect.

Content Knowledge Although the teachers’ average rating for their needs for
improving ‘‘My own understanding of big ideas in the subject’’ was only 3.07 out of
5 on the Likert scale question, in the open-ended responses, a considerable
percentage of teachers said they needed to improve their own content understanding
about the science topics they selected. Overall, 52 % of teachers explicitly
mentioned their needs for improving their content understanding. In particular,
65 % of teachers in Cohort 3 reported this need. For example, one fifth-grade
teacher in Cohort 3 stated: ‘‘Even though I have taught this topic [atmosphere], there
are many things I don’t truly understand. I feel uncomfortable with much of the
content.’’ One possible explanation for the gap between the ratings and open-ended
responses was that the teachers might believe they had a good understanding of ‘‘big
ideas’ in the subject, but lacked an in-depth content understanding.
PCK: Learners The most frequently mentioned needs were improving students’
content understanding and making science engaging and relevant to students by
connecting science to real life. In fact, all other needs that the teachers expressed
were intended to serve these goals, a finding elaborated later. Some teachers also
reported needs for designing age-appropriate lessons, differentiating instruction for
different learners, and addressing student misconceptions.
PCK: Instructional Strategies Consistent with the teachers’ ratings, inquiry
teaching was among the greatest needs for improvement reported by the teachers in
the open-ended responses. For example, a middle school teacher in Cohort 1 stated,
‘I find this topic [genetics/heredity] difficult to teach using problem-based/inquiry-
based, and I’d like to do a better job of this.’’ Because the PD project used the
problem-based learning approach for teacher learning, about half (83) teachers
became interested in using problem-based learning for their students. It seems that
the teachers did not differentiate inquiry-based learning from problem-based
learning, as they often mentioned the two approaches simultaneously. Another
frequently mentioned need was to find hands-on activities to engage students, a need
reported by 68 teachers. Fifteen teachers wanted to find better ways to represent the
science topic, and nine teachers wanted to help students make better connection
between activities and concepts. Six teachers wanted to incorporate technology in
science teaching. Fifteen teachers indicated that they needed to improve their
pedagogy in teaching the science unit in general.
PCK: Curriculum The greatest need that the teachers reported in this category was
aligning their teaching with state and district curriculum standards, particularly in
the last cohort due to the implementation of new state curriculum standards. The
teachers also needed to find more resources or learn to use existing resources to
improve their science units. Some teachers had to teach without a textbook. In
addition, the teachers needed to improve the organization of a unit, focus on big
ideas, and improve lesson flow and sequencing between lessons. A few teachers also
wanted to integrate literacy and mathematics into science lessons.
486 M. Zhang et al.
123
PCK: Assessment The teachers reported needs for designing assessment to
evaluate student learning and improving student performances in standardized tests.
For example, a teacher in Cohort 3 stated, ‘‘I would like to see my team work on
assessments for this unit. If we work on the assessment piece, the content and
lessons will fall into place.’’
Also, 21 teachers, with 15 from the last cohort, indicated that they needed
improvement in all areas. For example, two teachers in Cohort 3 commented, ‘‘This
[ecosystems] is a new topic for us. We are starting from scratch and need
everything!’’ and ‘‘I have not taught this unit [matter and energy] before, so
everything will need development and improvement.’’
Relationships Between Different Needs
It is also important to note the relationships between different needs. It appears that
the teachers ultimately wanted to achieve two goals: improvement in student
interest and content understanding. Other needs, such as improving teachers’ own
content knowledge, use of inquiry or hands-on activities, use of good resources, or
better ways of representation, were all means to achieve these goals. The following
teacher responses reflected the relationship.
I hope that the benefit of this professional development would be to increase
student interest thereby increase student learning. If student interest and
learning is increased then I am being fully fed as a teacher. [10th grade teacher
in Cohort 1]
More hands-on activities, to really help engage my students and increase their
understanding. [Kindergarten teacher in Cohort 2]
I have not taught force and motion for many years. I’m looking for good
problem/inquiry-based lessons to increase the depth of student understanding
and allow the students to enjoy the lesson. [6th grade teacher in Cohort 3]
How did Teachers’ Needs Vary Depending on Teacher Backgrounds?
We examined the relationship between teaching experience, grade level, and gender
and teachers’ needs for improvement using ANOVA and ttests.
Teaching Experience
The descriptive statistics of teachers’ needs for improvement by teaching experience
are presented in Table 6. A one-way between-subjects ANOVA was conducted to
compare the needs of teachers with different levels of experience. As shown in
Table 7, there was a significant effect of teaching experience on teachers’ needs for
improvement in four aspects: my own understanding of big ideas in the subject [F(2,
157) =3.442, p=.034]; teaching this unit with inquiry or scientific reasoning
[F(2, 158) =5.133, p=.007]; relating unit content to students’ lives [F(2,
115) =5.025, p=.008]; and addressing students’ misconceptions [F(2,

Tukey HSD test indicated that veteran teachers with more than 10 years of teaching
experience were more confident in teaching this unit with inquiry or scientific
reasoning and addressing students’ misconceptions than beginning teachers and
established teachers with 4–10 years of experience. Also, veteran teachers were
more confident in relating unit content to students’ lives than established teachers.
Grade Level
The descriptive statistics of teachers’ needs for improvement by grade level are
presented in Table 9. An independent-sample ttest was conducted to compare the
needs of elementary and secondary teachers. As shown in Table 10,ttest results
showed that the elementary teachers who taught Grades K-6 reported greater needs
for improving their own content understanding,developing effective assessments,

Gender
No significant difference was found between male and female teachers in any of the
nine aspects of teachers’ needs for improvement.
Discussion
Prior research has mainly focused on what makes PD effective from the program
design perspective (Garet et al., 2001; Penuel et al., 2007), while there is a lack of
understanding about what teachers need for improvement in the climate of

educational reforms and curricular changes. This study used the PCK framework to
examine teachers’ needs for PD situated in specific science topics.
First, this study identified a list of common science topics that teachers needed to
improve in life science, physics science, and earth science. For example, both
elementary and secondary teachers reported that they needed improvement in
teaching ecosystems, human body, and cells in life sciences, and force and motion

and matter and energy in physics science. These topics are also among the
disciplinary core ideas emphasized in the Next Generation Science Standards
(National Research Council, 2013). It is important to note that even some of the
experienced teachers with over 10 years of experience still perceived some of these
topics difficult to teach. For example, one high school teacher in Cohort 3 with
14 years of teaching experience hoped to improve his teaching of energy because ‘‘I
don’t feel I necessarily give students good concrete examples of everyday energy
changes.’ Prior research suggested that in general teachers grow their PCK with
more experience (Friedrichsen et al., 2009; Schneider & Plasman, 2011). However,
this study showed that it cannot be assumed that the growth will happen in all
science topics.
Second, this study further showed that teachers felt the needs to improve teaching
of certain topics for different reasons: themselves, students, and curricular changes.
The topic might be teachers’ own weak area due to a lack of training and interest.
The topic might be too abstract or complicated for students to understand. Also,
when new curriculum was implemented, many teachers had to design new units to
address the change. Opfer and Pedder (2011) argued that teacher professional
learning should be conceptualized to reflect ‘‘the complex teaching and learning
environments in which teachers live’’ (p. 377). Consistent with this view, this study
suggested that teachers’ needs for improvement were shaped by a complex teaching
system that involved both microcontexts (e.g., teachers, students) and macrocon-
texts (e.g., district- or state-level policy changes in curriculum and assessment). This
finding deepened our understanding of the complexity in teachers’ needs for
improvement.
Third, this study found that teachers needed improvement in various aspects of
PCK: learners, instructional strategies, curriculum, and assessment. In a review of
over 100 empirical studies on the challenges facing new science teachers, Davis
et al. (2006) found that the vast majority of the studies focused on preservice
teachers, with only a few looking at early-career teachers. Research on mid-career
and experienced teachers’ needs for improvement is also limited. This study
contributed to the literature by examining the needs of beginning, mid-career, and
experienced inservice science teachers. In addition, few studies have systematically
analyzed teachers’ needs for improvement using the PCK framework. This study
enhanced understanding of what inservice teachers needed to improve, what needs
were more common than others, and what the relationship among needs was. For
example, most teachers ultimately wanted to improve student content understanding
and engage students in learning. Other needs intended to help to achieve these goals.
This study found that inquiry teaching was one of the greatest challenges for
most teachers. Teaching science as inquiry has been advocated for over a decade
(National Research Council, 1996) and is emphasized in the Next Generation
Science Standards (National Research Council, 2013). Teacher preparation and
professional development programs have invested great effort to help teachers
understand and use inquiry teaching (Oliveira, 2010; Schneider & Plasman, 2011).
However, inquiry teaching remains difficult to most teachers. Although well-
prepared beginning teachers were able to implement inquiry-based science
instruction in their first year of teaching (Avraamidou & Zembal-Saul, 2010), this
492 M. Zhang et al.

study suggested that for most teachers, including experienced teachers, inquiry
teaching was still their greatest challenge (see Tables 5,6) and required significant
support from PD programs. This finding is consistent with previous research that
documented the challenges of inquiry teaching (Crawford, 2007; Johnson, 2006;
Wee, Shepardson, Fast, & Harbor, 2007).
Moreover, teachers’ needs may be affected by their teaching experience and the
level they teach. Beginning teachers and elementary teachers reported greater needs
for improvement in content, learner, curriculum, and assessment than did
experienced and secondary teachers. This finding provided additional evidence to
the particular challenges facing beginning elementary teachers. In their review,
Davis et al. (2006) found that mixed results were reported on preservice secondary
teachers concerning their content knowledge, but ‘‘in almost all of the studies
reviewed here, the [preservice elementary] teachers were found to have unsophis-
ticated understandings of science’’ (p. 614). Our study suggested that similar
differences remained between inservice elementary and secondary teachers.
In particular, the Cohort 3 teachers reported greater needs for improving their
own content understanding and student understanding, using inquiry-based
approaches, and aligning with standards due to the implementation of new state
curriculum standards. For example, 81 % of teachers in Cohort 3 reported that they
needed to improve their units to better align with the standards, compared to only
27 and 23 % in the previous two cohorts, respectively. A sizable number of Cohort
3 teachers reported that they had to design a new unit from scratch and had to teach
unfamiliar topics, which made them frustrated and anxious. In fact, the number of
participants in the last cohort increased dramatically from the first 2 years, mainly
due to the change of curriculum standards. This finding reinforced the importance of
PD support in helping teachers to adapt to curricular changes (Jones & Eick, 2007).
Implications of the Study
Effective PD that aims to improve teachers’ classroom practice should be aligned
with teachers’ needs. If the areas that teachers need to improve can be clearly
identified, then it will be easier to develop responsive PD programs to address these
needs. Thus, the findings of this study have important implications for educational
researchers, teacher educators, and PD providers by pointing out promising
directions to invest their valuable time and resources. First, PD designers should
target the common topics that many teachers find difficult to teach, such as
ecosystems and force and motion. Second, many teachers in this study perceived
inquiry teaching to be the greatest challenge in their science instruction. Therefore,
more efforts should be made to help teachers, particularly those who lack teaching
experience, learn to use inquiry to teach specific science topics. Third, PD design
should take into account teacher background in teaching experience and grade level.
PD programs that focus on beginning elementary teachers are much needed. Finally,
this study showed that teachers needed considerable PD support when adopting new
curriculum standards. This finding has important implications because both the

In addition to research on effective professional development (PD), understanding how teachers view PD facilitates research-practice communication. Qualitative analyses of interviews (N = 43 teachers) revealed that teachers' views differ from the research perspective. By mentioning active learning and service provision as primary PD features, teachers took on a pragmatic and service-oriented understanding. Teachers further endorsed short PD and relief measures but overlooked knowledge acquisition and student results as reasons for PD. This suggests that teachers orient themselves more towards resources than towards outcomes of PD. Finally, teachers prioritised emotions. A framework to address PD views in research-practice communication is proposed.

p> Keeping a teaching journal is one way that can be done to assist in the improvement of professional development. One approach that is becoming increasingly popular nowadays. Using a qualitative case study methodology, this research aims to explore the English teachers' perspectives on journal writing as a way of professional development. The study enlisted the participation of 21 English teachers to complete a demographic survey. In accordance with the aims of the study, participants were recruited using a technique of purposive sampling. In this case, the researcher selected the participant based on their experience in writing a teaching journal. The researcher utilized a questionnaire and an interview as instruments for data collection. The purpose of the questionnaire is to collect demographic information as well as respondents' perceptions about the benefit of keeping a teaching journal for professional development. The interview was then conducted to obtain further information regarding the participants' responses to the questionnaire. Five English teachers voluntarily participated in the interview process and in analyzing data, thematic content analysis was used in this study. The outcomes of the study revealed that English teachers got a range of benefits from strengthening their professional development, including encouraging a positive attitude toward teaching, enhancing English teachers' critical thinking, and improving teaching quality. This study suggested that keeping a teaching journal has a profound influence on English teacher development. </p

Recently, technology use has gained considerable importance in both instructional activities conducted in the classroom environment and the distance education process. Accordingly, the need for teaching materials has arisen. It is thought that simulations can meet this need, especially for subjects that might cause physical material supply problems during teaching. Considering this situation, this paper introduces a material development study using the Algodoo simulation program for teaching the subject of colors of light. The material developed in this study is based on three objectives of the tenth-grade physics courseteaching program declared by the Turkish Ministry of National Education. The study details the developmental stages and experimental results of two simulations. Thus, it is expected that teachers and students can use the material introduced in this study easily with the help of the Algodoo program, which can be constructed for tablets and computers quickly and free of charge.

Continuous Professional development (CPD) has received growing attention in teacher education research since it has the potential to affect teacher learning. Despite this, studies on EFL teachers' needs for CPD have been limited. To bridge this gap, this study investigated EFL teachers' reflections on and target needs for CPD. This study employed a mixed-methods research design, which involves both quantitative and qualitative approaches to answer the research questions. The research participants included 20 EFL teachers teaching at government high schools, and the data were collected using a test, questionnaires, and interviews. The findings indicated that EFL teachers have different views of their lacks, wants, and necessities. Furthermore, EFL teachers reflected that the current CPD program, which is practiced in their school, was never conducted to help them develop their profession. At the 0.01 level (2-tailed), there was a strong, negative correlation between EFL teachers’ CPD target needs and their reflections on the current CPD (rs = -0.961, n = 20, p = 0.01). Finally, the study recommends revising the CPD program; stakeholders should conduct program evaluations and then incorporate teachers’ reflections and target needs for CPD.
... Systematic research has been done on teachers' knowledge, nature, built and rebuilt, and how they affect teaching practice. Especially in physical sciences, research on students' ideas, which dominated the last decade, seems to lead, and influence research on teachers' ideas and perceptions (Zhang et al., 2015). It is even argued that many corrective changes attempted in the past have failed because teachers' existing knowledge and beliefs have not been considered (Van Driel et al., 2002). ...

This paper describes an empirical study (n=352) into Greek in-service primary school teachers' conceptions of concepts of force and weight. A closed multiple-choice questionnaire is given to primary school teachers as a tool to explore conceptions, which has been used in previous research. The study population consisted of teachers at primary schools who work in the Greek education directorate. The research data is related to the teachers' years of service, from where it is studied whether their teaching experience changes/reduces the alternative conceptions. The research data investigated whether the teachers' teaching experience alters or reduces alternative conceptions based on their years of service. Years of service correlate statistically significantly with most questions. In particular, our results indicate that the alternative conceptions of teachers, reflecting misconceptions and preconceptions, reduce as the years of professional experience increase. Our study can be employed in science teaching, the design of Curricula, and teachers' professional development.

In-service professional development is important for improving teaching. However, little research has examined how the roles, beliefs, and backgrounds of the individuals providing professional development can best be leveraged to create effective professional development programmes. A particularly understudied group are community-based On-Site Teacher Educators (OSTEs) who can serve as the bridge between university-based faculty and school employees. OSTEs are aware of the realities of classroom spaces, yet work outside of them, giving them a hybrid capacity to support teacher learning. In this exploratory qualitative multiple case study, the perspectives and practices of three OSTEs are examined as they supported elementary science teachers (n = 119) in multi-year professional development. Findings indicate that OSTEs have strong alignment between their professional development practices and their beliefs about knowledge and learning. OSTEs revealed that they are introspective about managing the gap between university faculty and classroom teachers. Cross-case analysis revealed that OSTEs identify a tension between affirming teachers as professionals and productively challenging teachers' assumptions. To address this, they use modelling, co-teaching, and dialogue inside a stance of teaching as intellectual work. In sum, this research suggests that professional development provided by OSTEs can lead to transformative change in schools. ARTICLE HISTORY

Educational change and innovation are needed to improve the quality and equity of education around the world. Teachers are therefore expected to make changes and to innovate both in their theoretical approaches and their practice. However, considerable variation can be found in the profession with regard to change and innovation. In particular, differences can be identified depending on teachers' age, career stage and generation. There is a paucity of research on these differences. To address this gap, a qualitative study focused on teacher orientation towards change and innovation was conducted. Data collected from discussion groups and interviews were analysed thematically. The findings indicated that the participants shared a similar understanding of change and innovation. However, data also showed differences regarding participants' orientation towards change and innovation that they attributed to age, professional experience, and various circumstances in their careers that were linked to their professional generations.

Background and Context Based on issues arising around how to best prepare CS teachers and the constantly changing nature of the CS education content, curriculum, and instructional methods, it is crucial to examine the needs of secondary CS teachers. Objective The primary purpose of this study was to identify secondary computer science (CS) teachers’ needs and make recommendations for future CS education research and practices in the U.S. Method Using a mixed-method research design, the data were collected from Computer Science Teachers Association (CSTA)’s email listserv member discussions (n = 1,706 from 482 unique members), questionnaire responses from 222 secondary CS teachers, and semi-structured interviews with eight CS teachers in the US. Findings Updating curriculum resources was an important ongoing need for secondary CS teachers. Curriculum resources, materials to assess students learning, and embedding the principles of computational thinking into curriculum were reported as major needs for secondary teachers. Teachers also reported that they need to learn more about student-centered teaching strategies (e.g. problem-based learning and pair programming) and guide students’ learning using scaffolding and team-management strategies. The findings suggest that teachers perceived the need for administrators’, parents’, and other CS teachers’ support. Having an online community for teachers was critical to address their curricular and pedagogical needs. Furthermore, increasing student enrollment and interest in CS was critical for the future of CS education.

This chapter briefly reviews the research related to the construct of pedagogical content knowledge (PCK) over the past 25 years. Despite the remarkable implications of the PCK conceptualization, questions remain concerning the vagueness of the construct and the studies conducted on the PCK research line, questions which may lead to new developments in defining the nature of the conceptualization, its validity, and its utility. However, agreement exists concerning the need to portray specific cases of PCK of successful teaching. The work argues for a need to develop models of teacher learning and professional development that are subject matter specific. The chapter ends with a call for basing professional development on the conceptualization of PCK.

Why is technology not used more in schools? Many researchers have tried to solve this persistent puzzle. The authors of this article report on their study of technology uses in 19 schools. They suggest an ecological metaphor, using the example of the introduction of the zebra mussel into the Great Lakes, to integrate and organize sets of factors that affect implementation of computer uses. Their findings suggest that an ecological perspective can provide a powerful analytical framework for understanding technology uses in schools. That perspective points out new directions for research and has significant policy and practical implications for implementing innovations in schools.

Since its emergence over two decades ago, the construct of pedagogical content knowledge (PCK) has significantly impacted preservice and inservice teacher education, educational policy, and educational research. PCK has served to re-focus educators' attention on the important role of subject matter in educational practice and away from the more generic approach to teacher education that dominated the field prior to 1975. This ambitious text is the first of its kind to summarize the theory, research, and practice related to pedagogical content knowledge. The audience is provided with a functional understanding of the basic tenets of the construct as well as its applications to research on science teacher education and the development of science teacher education programs. The authors are prominent educators representing a variety of subject matter areas and K-12 grade levels. Although the focus of the text is science education, it should provide valuable reading for any individuals with interests in professional teacher education.

The current science education reform movement emphasizes the importance of professional development as a means of improving student science achievement. Reformers have developed a vision for professional development based upon intensive and sustained training around concrete tasks that is focused on subject-matter knowledge, connected to specific standards for student performance, and embedded in a systemic context. Using data from a National Science Foundation Teacher Enhancement program called the Local Systemic Change initiative, this study employs hierarchical linear modeling to examine the relationship between professional development and the reformers' vision of teaching practice. The findings indicate that the quantity of professional development in which teachers participate is strongly linked with both inquiry-based teaching practice and investigative classroom culture. At the individual level, teachers' content preparation also has a powerful influence on teaching practice and classroom culture. At the school level, school socioeconomic status was found to influence practice more substantially than either principal supportiveness or available resources. (C) 2000 John Wiley & Sons, Inc.

Learning progressions are the successively more sophisticated ways of thinking about an idea that follow one another over a broad span of time. This review examines the research on science teachers’ pedagogical content knowledge (PCK) in order to refine ideas about science teacher learning progressions and how to support them. Research published between 1986 and 2010 relevant to science teacher learning and PCK was examined for what ways teachers’ knowledge becomes more developed and what appears to be the sequence. Analysis indicates that it is helpful for teachers to think about learners first, then to focus on teaching, and points out the essential role of reflection for teachers to rearrange their ideas in ways that develop their PCK. This review takes a unique approach to thinking about research on what science teachers learn and can support teacher educators in designing professional programs that support beginning and advanced learning for science teachers.

Providing support focused on real challenges is critical in retaining highly qualified new science teachers, but the field lacks a systematic description of these teachers’ needs. The authors of this article examine the areas that science teachers are expected to understand: (1) the content and disciplines of science, (2) learners, (3) instruction, (4) learning environments, and (5) professionalism. They review the literature on challenges facing preservice and early-career science teachers, identify issues on which conventional wisdom is supported or called into question, and highlight the areas where the existing research is inadequate as a basis for generalization. For example, the authors found few studies on how new science teachers use curriculum materials or how they understand scientific inquiry. Their overview of challenges is followed by a discussion of how these teachers can be supported.
