We explore how experienced informal educators worked towards equitable and consequential opportunities for learning in informal STEM settings through pedagogical practice. Drawing from a justice-centered social practice stance we argue that pedagogical practice that promotes social transformation towards more just futures must confront and respond…

This review examines 105 empirical studies that investigate students' views of the nature of science (VNOS), effects of curricular interventions on changing students' VNOS, and relations between VNOS and demographics, majors, and learning of science. The reviewed studies can be categorized into three theoretical frameworks: the unidimension, the…

Research hypotheses versus statistical hypotheses, null hypotheses and alternative hypotheses, and statistical significance versus practical significance are described and illustrated. (CP)

Partnerships of teachers with scientists are thought to be important for many aspects of science education reform, but it is not always clear how to make such partnerships productive. Between 1994 and 1997, high school teachers were partnered with scientists, to design yearlong ecological research projects in which the teachers were learning for…

Reports the presence of a facilitating effect of exposure to a pretest on the Watson-Glaser score and a posttest following grade 12 biology instruction. (AL)

Lakatos's methodology of scientific research programs is summarized and discussed for Piagetian schools and alternative conceptions movement. Commonalities/differences between these two rival programs are presented along with fundamental assumptions, auxiliary hypotheses, and research policy. Suggests that research findings should not be merely…

Suggests that an evaluation of the questions asked in inquiry training episodes may not reflect the logical progression of steps designed to formulate explanations or hypotheses, but also depend on students' disposition towards approval, tendency to minimize risk, and motivation by external factors. Studies of inquiry behavior should include…

Engagement has been viewed as an important construct to understand students' learning performances in classroom settings. Taking an interactive perspective, the study investigates ninth graders' cognitive, emotional, and behavioral engagement in teacher-centered (TC) and student-centered (SC) technology-enhanced classrooms. 54 students from two…

Findings show that students value homework, that few teachers regularly check homework, and that there are sex differences between Arab and Jewish…

Describes evaluative data obtained during the Colorado Elementary Science Project which used elementary teachers to provide inservice training for other teachers after intensive experience with one of the national elementary science projects. Makes recommendations for implementation and change of this diffusion model. (AL)

This article is the first of a four part series of a study of Canadian high-school graduates' views on science-technology-society (STS) topics. It describes the research scope and methodology and discusses research issues associated with use of the specially constructed survey instrument, Views on Science-Technology-Society (VOSTS). (ML)
