A recent analysis of the Longitudinal Study of Young People in England (LSYPE) indicates a White British-Black Caribbean achievement gap at age 14 which cannot be accounted for by socio-economic variables or a wide range of contextual factors. This article uses the LSYPE to analyse patterns of entry to the different tiers of national mathematics…

This dissertation consists of three chapters that examine the effects of school and students improvement interventions. The first chapter investigates whether, for whom, and under which conditions high school mathematics and science course graduation requirements (CGRs) affect student achievement and educational attainment. Drawing on data from…

Steven F. Maier, winner of the Award for Distinguished Scientific Contributions, is cited for his work in the fields of learned helplessness; cytokines, depressed mood, and cognitive interference; and the brain structures that produce and counteract learned helplessness. In addition to the citation, a biography and selected bibliography of Maier's…

This second volume of the Third International Mathematics and Science Study (TIMSS) 1999 Video Study Technical Report focuses on every aspect of the planning, implementation, processing, analysis, and reporting of the science components of the TIMSS 1999 Video Study. The report is intended to serve as a record of the actions and documentation of…

Instructional strategies in science that fail to identify students' initial understanding of scientific concepts may leave students' flawed ideas unchanged, thus affecting their ability to synthesize, differentiate, and connect to new information in science. The purpose of this quantitative study was to examine the relationship between concept…

The aim of this study was to investigate the effects of teacher-centered and student-centered analogies on student academic achievement, conceptual understanding and attitude, concerning the topic of the circulatory system in a science and technology lesson. A quasi-experimental design was used. The sample consists of 49 sixth grade students in…

Recent advances in mobile and wireless communication technologies have enabled various new learning approaches which situate students in environments that combine real-world and digital-world learning resources; moreover, students are allowed to share knowledge or experiences with others during the learning process. Although such an approach seems…

The purpose of this study is to examine the effect of two strategies for negotiating the question for exploration during science inquiry on student achievement and teachers' perceptions. The study is set in the context of the Science Writing Heuristic. The first strategy (small group) consisted of each group of four students negotiating a question…

The success of the United States in the 21st century will depend on the ideas and skills of its population. These have always been the nation's most important assets. As the world becomes increasingly technological, the value of these national assets will be determined by the effectiveness of science, technology, engineering, and mathematics…

Research and development of measures to document ongoing learning within the content areas are in the beginning stages. As such, the current study adds to efforts in the development of the vocabulary-matching measure. Using a modified format of the previously studied vocabulary-matching measure, 63 middle school students completed alternate forms…

Submicrorepresentations (SMRs) are a powerful tool for identifying misconceptions of chemical concepts and for generating proper mental models of chemical phenomena in students' long-term memory during chemical education. The main purpose of the study was to determine which independent variables (gender, formal reasoning abilities, visualization…

The purpose of this study was to investigate the effects of the Common Knowledge Construction Model (CKCM) lesson sequence, an intervention based both in conceptual change theory and in Phenomenography, a subset of conceptual change theory. A mixed approach was used to investigate whether this model had a significant effect on 7th grade students'…

The purpose of this study was to investigate the influence of gender and knowledge on scientific creativity among form three biology students (third year in secondary school cycle) in Nakuru district in Kenya. The cross- sectional survey research was employed. A sample of eight schools with a total of 363 students was selected from the population…

In this study, an attempt was made to develop a method of measurement and evaluation aimed at overcoming the difficulties encountered in the determination of the effectiveness of chemistry education based on the goals of chemistry education. An Analytic Hierarchy Process (AHP), which is a multi-criteria decision technique, is used in the present…

The purpose of this study was to investigate Turkish primary students' scientific process skills under the theoretical framework of cognitive domain. The sample set consisted of 306 sixth and seventh grade students from public, private, and bussed schools. The Turkish Integrated Process Skill Test was used to measure scientific process skills, and…
