We investigated what a cognitive framework for measuring classroom teaching could reveal about (a) the impact of a professional development (PD) program on teaching practices and (b) the relationship between teaching practices and student science learning. To conduct this study, we leveraged a collaboration between two entirely independent projects. The first project had developed a framework, the Teacher Tasks and Questions (TTQ) coding framework, for measuring teaching. The second project, the Science Teachers Learning From Lesson Analysis (STeLLA-1) project, possessed a rich body of teaching and student learning data. The two projects’ independence from each other allowed us to examine the generalizability of the TTQ framework and to investigate its validity. The TTQ measures were applied to the data set from the STeLLA-1 project. We examined whether the TTQ measures detected meaningful changes in teaching practice from pre-PD to post-PD and whether they predicted student learning. We found that the TTQ measures did detect changes in teaching practices that were consistent with STeLLA-1’s aims; furthermore, some TTQ measures also predicted student learning. We discuss the value of having generalizable measurement frameworks that can be used across different studies. We also glean lessons about data sharing across independent projects.

In a longitudinal group-randomized trial, we explore the key role of the quality of classroom text discussions in mediating the effects of Content-Focused Coaching (CFC) on student reading achievement (2983 students, 167 teachers). Schools in the United States serving large numbers of minority and English language learning (ELL) students from low-income families were randomly assigned to participate in the CFC literacy-coaching program or to continue with the literacy coaching that was standard practice for the district. The findings identified a positive effect of the CFC program on observed classroom text discussion quality. Supporting the theory underlying CFC, the positive effect of the program on student reading achievement was mediated through the quality of classroom text discussions. Students' language status moderated the direct effect of the program, with stronger effects for ELL students compared to their English-proficient peers.

This study examines the effect of a comprehensive literacy-coaching program focused on enacting a discussion-based approach to reading comprehension instruction (content-focused coaching [CFC]) on the quality of classroom text discussions over 2 years. The study used a cluster-randomized trial in which schools were assigned to either CFC or standard practice in the district for literacy coaching. Observers rated classroom text discussions significantly higher in CFC schools. Teachers in the CFC schools participated more frequently in coaching activities that emphasized planning and reflecting on instruction, enacting lessons in their classrooms, building knowledge of the theory underlying effective pedagogy, and differentiating instruction than did the teachers in the comparison condition. Qualitative analyses of coach interviews identified substantive differences in the professional development support available to coaches, scope of coaches’ job responsibilities, and focus of coaching resources in the CFC schools and comparison schools.

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis-of-practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year-long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi-level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011

Teacher mobility is a factor that impacts schoolwide implementation of professional development programs. In this article, we present interim results of a longitudinal randomized field trial of a comprehensive literacy coaching program (Content-Focused Coaching, CFC) for improving instruction and learning in schools with high teacher mobility.Weinvestigate program effects on 73 new treatment and comparison teachers recruited to replace the large proportion of teachers who left their schools during the first year of the program. HLM analyses indicated that the CFC program predicted significantly higher school-level gains on the state standardized test for English language learners (N=496, ES=.51). By spring, the quality of teachers' self-reported and observed instruction in the CFC schools exceeded that of comparison teachers. Implications for accommodating new teachers into an ongoing and established coaching program to improve instruction and student learning, and conducting randomized trials in schools with high teacher turnover, are discussed.

This study investigates the influence of a school’s pre-existing social resources on the implementation of a comprehensive literacy-coaching program (Content-Focused Coaching [CFC]). Elementary schools were randomly assigned to receive a CFC-trained coach ( n = 15 schools) or to continue with the literacy coaching resources that are standard for the district (n = 14 schools). Ninety-six fourth-and fifth-grade teachers participated in the study (n = 63 CFC and n = 33 comparison). Survey results indicate that teachers in the CFC schools participated more frequently in the coaching activities that emphasized planning and reflecting on instruction, enacting instruction, and building knowledge of the theories underlying effective reading comprehension instruction compared to teachers in the comparison schools. After 1 year, teachers strongly believed that CFC coaching helped improve their instructional practice. Principal leadership was the key resource supporting implementation of the program positively predicting greater teacher participation in coaching activities and perceived usefulness of these activities along with coaches’ training in the CFC program and less experienced teachers. Unexpectedly, a school’s pre-existing culture of teacher collaboration negatively predicted teachers’ coaching experiences. CFC coach interviews contribute to understanding the interactions of social resources within schools that facilitated or hindered program implementation. Implications for the design and implementation of effective instructional coaching policies in districts are discussed.
