Intellectually disabled (ID) students in secondary education are often taught in an individual setting where video instruction is used. Especially, when the instruction is about complex assignments, many students may forget parts of it. In this study, we tried to find out if prompting ID students to explain video instruction would help them to impr...
For primary school students, mathematical word problems are often more difficult to solve than straightforward number problems. Word problems require reading and analysis skills, and in order to explain their situational contexts, the proper mathematical knowledge and number operations have to be selected. To improve students' ability in solving wo...
In the last two decades Dutch primary school students scored below expectation in international mathematics tests. An explanation for this may be that teachers fail to adequately assess their students’ understanding of learning goals and provide timely feedback. To improve the teachers’ formative assessment practice, researchers, curriculum experts...
In the Netherlands, students with intellectual disabilities (ID) attend practical education (PE). Teachers generally use demonstration as a form of direct instruction (DI) and students have difficulty working independently. Strategy instruction (SI) is a question-answer-based method that stimulates students' autonomy by getting them to verbalize ta...
Teachers in primary education experience difficulties in teaching word problem solving in their mathematics classes. However, during controlled experiments with a metacognitive computer programme, students' problem-solving skills improved. Also without the supervision of researchers, metacognitive computer programmes can be beneficial in a natural...
Metacognitive monitoring and regulation play an essential role in mathematical problem solving. Therefore, it is important for researchers and practitioners to assess students’ metacognition. One proven valid, but time consuming, method to assess metacognition is by using think-aloud protocols. Although valuable, practical drawbacks of this method...
Pupil population in practical education consists mainly of 12-18 year olds with a (slight) mental retardation. The main goal of practical education is to teach these pupils to exercise a profession independently. There are doubts about the effectiveness of teaching methods in practical education (Blik & Harskamp, 2005). Thirty-eight teachers in yea...
The aim of this study is to examine the effectiveness of collaborative learning with hints and peer tutoring with hints, and individual learning with hints in chemistry laboratory education in a secondary school. A total of 96 eleventh graders participated in this study. The study has a randomized pre‐test and post‐test design with a delayed post‐t...
The aim of the study is to investigate the influence of gender and gender pairing on students’ learning performances and knowledge elaboration processes in Computer-Supported Collaborative Learning (CSCL). A sample of ninety-six secondary school students, participated in a two-week experiment. Students were randomly paired and asked to solve severa...
This study examines the impact of interventions in mathematics education in K-6 classrooms through a systematic review of research literature in the period 2000 -2010. A meta-analysis of 69 independent effect sizes extracted from 40 primary studies involving a total of 6817 students indicated a statistically significant positive average effect (Coh...
Introduction: The study investigated the degree to which students' statistical reasoning abilities, statistics self-efficacy, and perceived value of statistics improved during a reform based introductory statistics course. The study also examined whether the changes in these learning outcomes differed with respect to the students' mathematical back...
Despite frequent instructional reforms, statistics remains the most difficult and stressful course domain for many university social science students. It is assumed by some researchers that students' self-efficacy beliefs and their feelings about teacher support affect students' achievement and exam results. In this study, we tested empirically whe...
Solving word problems plays an important role in primary school mathematics education. However, many students have difficulty solving such tasks. In order to improve students' metacognitive and problem-solving skills, a computer program was developed consisting of word problems and metacognitive hints. The experimental group of Grade 5 (n = 23) pra...
This study investigates the effectiveness of computer-delivered hints in relation to problem-solving abilities in two alternative indirect instruction schemes. In one instruction scheme, hints are available to students immediately after they are given a new problem to solve as well as after they have completed the problem. In the other scheme, hint...
Background: Cooperative learning may help students elaborate upon problem information through interpersonal discourse, and this may provoke a higher level of thinking. Interaction stimulates students to put forward and order their thoughts, and to understand the ideas or questions of their peer learner. However, partner gender is an important varia...
Many students experience difficulties in solving applied physics problems. Most programs that want students to improve problem-solving
skills are concerned with the development of content knowledge. Physhint is an example of a student-controlled computer program
that supports students in developing their strategic knowledge in combination with supp...
Many students experience difficulties in solving applied physics problems. Researchers claim that the development of strategic knowledge (analyze, explore, plan, implement, verify) is just as necessary for solving problems as the development of content knowledge. In order to improve these problem-solving skills, it might be profitable to know at wh...
This paper evaluates the effectiveness of a student controlled computer program for high school mathematics based on instruction principles derived from Schoenfeld’s theory of problem solving. The computer program allows students to choose problems and to make use of hints during different episodes of solving problems. Crucial episodes are: analyzi...
This study demonstrated that the modality principle applies to multimedia learning of regular science lessons in school settings. In the first field experiment, 27 Dutch secondary school students (age 16–17) received a self-paced, web-based multimedia lesson in biology. Students who received lessons containing illustrations and narration performed...
Many theories on college retention recognize the significance of student satisfaction as a positive factor in students’ persistence.
Yet, there are few theories that address the relationship of degree program satisfaction to study behaviour and dropout. This
paper explores the impact of degree program satisfaction on academic accomplishment and dro...
Empirical evidence is presented that males working in mixed-gender dyads on science problems do better than their female partners. This is not the case when males and females work in same gender dyads. There is a difference in communication style in mixed gender dyads in comparison with same gender dyads. In mixed gender dyads females ask more ques...
The research issue in this study is how to structure collaborative learning so that it improves solving physics problems more than individual learning. Structured collaborative learning has been compared with individual learning environments with Schoenfeld's problem-solving episodes. Students took a pre-test and a post-test and had the opportunity...
Mathematics teachers often experience difficulties in teaching students to become skilled problem solvers. This paper evaluates the effectiveness of two interactive computer programs for high school mathematics problem solving. Both programs present students with problems accompanied by instruction on domain-specific knowledge required in different...
Research has shown that female students cannot profit as much as male students can from cooperative learning in physics, especially in mixed-gender dyads. This study has explored the influence of partner gender on female students’ learning achievement, interaction and the problem-solving process during cooperative learning. In Shanghai, a total of...
The main goal of most physics textbooks is to develop declarative and procedural knowledge. Exercises provide pupils with opportunities to apply this knowledge. However, when confronted with more complicated exercises many pupils experience difficulties in solving them. A computer program about the subject of forces was developed containing hints f...
In a one-year functions and calculus course using a common textbook, three classes of Grade 10 students worked with graphics
calculators throughout, five classes worked with graphics calculators for about two months, and four classes did not use graphics
calculators. Posttest results showed that the students who had worked with graphics calculators...
Explores how the use of the graphics calculator may lead to changes in students' solution approaches and how these changes affect student achievement. Concludes that only prolonged use of the graphic calculator leads to enrichment of the solution repertoire of students and a better understanding of functions. (Contains 11 references.) (Author/ASK)
Presents an experiment carried out at the University of Groningen where pretest-posttest design was used including two experimental conditions with the graphics calculator (TI-81) and one control condition without the calculator. Results point toward a change in teacher instructional behavior and in pupils' problem-solving approaches. Contains 14 r...
Pass rates in courses for vocational (re)schooling of adults are generally low. Lack of mathematical skills is one of the factors that can be responsible. To enhance pass rates, most courses supply additional mathematics schooling. The present study investigated whether the effectiveness of additional mathematics schooling can be improved by new ma...
Research on education often faces the problem of measurement of the opportunity to learn. This is also the case with mathematics education. Researchers may choose either a retrospective measurement approach (e.g., a questionnaire) or an immediate recording approach (e.g., logbooks). In the present study, the accuracy, reliability, and predictive va...
Many students often experience difficulties in solving applied physics problems. The causes of failure can be traced back to a lack of knowledge of the concepts and procedures of physics, or to a lack of strategic knowledge required to solve problems systematically. Many researchers claim that the development of strategic knowledge is just as neces...
Al heel lang probeert men leerlingen vaardigheden aan te leren door de vaardigheden op te splitsen in deelvaardigheden en deze achtereenvolgens te oefenen. Voor het uitvoeren van de eindvaardigheid moeten de deelvaardigheden worden samengevoegd door de lerende. Dat kan vooral problemen opleveren bij de lerende wanneer de eindtaak complex is. Daaren...
Door de landelijke pedagogische centra zijn er ontwikkelingen in gang gezet richting vraaggestuurd Praktijkonderwijs. De traditionele handelingsplannen zijn aan verandering toe en worden vervangen door individuele ontwikkelingsplannen waarin de nadruk ligt op de wensen en de mogelijkheden van de leerlingen. Het werken met individuele ontwikkelingsp...
