This article examines how international differences in age-grade distributions and grade effects contribute to science scores among 27 Organization for Economic Cooperation and Development countries. As shown in the 2006 Program for International Student Assessment, countries vary substantially in the grade distribution of 15-year-olds. The costs…

Undergraduates entering science curricula differ greatly in individual starting points and learning needs. The fast pace, high enrollment, and high stakes of introductory science courses, however, limit students' opportunities to self-assess and modify learning strategies. The University of Washington's Biology Fellows Program (BFP) intervenes…

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…

This paper reviews Ghana's performance in the TIMSS 2011 survey in comparison with other African and some high performing countries which participated in the TIMSS assessment. Students' achievement in the science content areas assessed were summarized and teacher preparation constructs of teachers of the students who took part in the assessment…

The current research aims to explore the effects of a haptic augmented simulation on students' achievement and their attitudes towards Physics in an immersive virtual reality environment (VRE). A quasi-experimental post-test design was employed utilizing experiment and control groups. The participants were 215 students from a K-12 school in…

Various indicators suggest that math and science students in many developing countries are lagging behind their counterparts in other nations. Using Madagascar as a case study, we aimed to: (1) evaluate the effectiveness of education among those enrolled in science and math programs at primary, secondary, and university institutions; and, (2)…

This year-long, quasi-experimental study investigated the impact of the use of netbook computers and interactive science software on fifth-grade students' science learning processes, academic achievement, and interest in further science, technology, engineering, and mathematics (STEM) study within a linguistically diverse school district in…
