Chemical bonding is central to explaining many phenomena. Research in chemical education and the Framework for K-12 Science Education (the "Framework") argue for new approaches to learning chemical bonding grounded in (1) using ideas of the balance of electric forces and energy minimization to explain bond formation, (2) using learning…

Although promoting student interest is a pivotal educational goal, student interest in science, and particularly in physics, declines substantially during secondary school. This study focused on the long-term development of interest in physics at the lower secondary level (grades 5-7) and examined the role of teaching and teaching quality on the…

We present results of an investigation of university students' development of mathematical models of motion in a physical science course for preservice teachers and graduate students in science and mathematics education. Although some students were familiar with the standard concepts of position, velocity, and acceleration from physics classes,…

Finnish students' opinions about the frequency of learning activities and communication in the Finnish science classroom, their interest in science and science studies and careers, their sense of self-efficacy, and their beliefs about their own competence as well as their performance in science are analyzed based on PISA 2006 Scientific Literacy…

Reports on the analysis of science curricula carried out across Canada within the framework of the Second International Science Study by: (1) describing the background to the study and the research methodology employed; (2) showing how data were organized; and (3) discussing meanings derived from the data analysis.

Examines science textbook language and determines some characteristics of them: distant authorial voice, concern for precision, limited context, limited syntax, and rhetorical model. Suggests three further researcher needs. (YP)

Investigates the extent to which thinking skills and mathematical competency would predict the course performance of freshman and sophomore science majors enrolled in physics courses. Finds that algebra ability and critical thinking skills were the best predictors. (Author/YP)

Reviews research on children's ideas about floating and sinking. Describes the Model-Assisted Reasoning in Science (MARS) project curriculum and student responses to a question about helium balloons. Contains 61 references. (DDR)

Presents data on student performance in a competency-based, multiple-opportunity format physics course, indicating that costs are related to character of examination questions and comprehensional modes of students. Compares costs for single/multiple trial formats, showing that multiple-trial opportunity has lower costs and a higher yield of…

Outlines an in-depth case study of teachers' use of image processing in biology, earth science, and physics classes in one high school science department. Explores issues surrounding technology implementation. Contains 21 references. (DDR)

This investigation examines the difficulties encountered by one graduate teaching assistant as she taught "Physics for Elementary Education," a large-enrollment, inquiry-based science course taught at a public Midwestern university. The methodological approach of hermeneutic phenomenology served as the lens to investigate the research question,…

Describes and examines the effects of the eight-week Summer Science Training Program at the University of Iowa. There was no significant differences between students who had completed high school physics and those who had not on the final course examination, course grade, and attitudes toward physics. (Author/YP)

Recent literature in science education suggests that, to transform girls' participation, learning, and identities within school science, we must think about ways to engage girls in different kinds of educational activities that promote broader meanings of science and scientist. This study was designed to examine more deeply this call for a changed…

Argues that research for teacher use would be more effective if it were: (1) of the form referred to as naturalistic case studies and (2) oriented toward discovering cognitive and social interaction mechanisms underlying the learning processes in classrooms. (Author/SK)

Compares changes in attitudes toward science and open-mindedness in treatment and nontreatment groups of preservice elementary teachers enrolled in an inquiry-oriented methods course and an expository freshman physics course, respectively. Concludes that course design effects a difference in attitude and open-mindedness. (CS)
