We assessed the impact of teaching methodological aspects of physics on students' scientistic beliefs and subject interest in physics in a repeated-measurement design with a total of 142 students of upper secondary physics classes. Students gained knowledge of methodological aspects from the pre-test to the post-test and reported reduced…

"Problem-based learning" (PBL) is one of an innovative learning model which can provide an active learning to student, include the motivation to achieve showed by student when the learning is in progress. This research is aimed to know: (1) differences of physic learning result for student group which taught by PBL versus expository…

This mixed method study explored Christian teachers' beliefs in religious schools on evolution, their attitudes toward evolution, and their perceptions on the effect of those beliefs on the teaching of evolutionary content. Teachers (N = 52) from Association for Christian Schools International (ACSI) accredited schools in California and Hawaii…

This study examined the effects of teachers' biology-specific dimensions of professional knowledge--pedagogical content knowledge (PCK) and content knowledge (CK)--and cognitively activating biology instruction, as a feature of instructional quality, on students' learning. The sample comprised 39 German secondary school teachers whose lessons on…

Theories on learning with Multiple External Representations (MER) claim that low prior knowledge learners in science have difficulties using MER, which are seen as necessary to achieve a conceptual understanding. In two experiments, we analyze the mechanisms underlying the learning of chemistry with MER. Our first experiment focuses on how MER can…

Many conventional science courses contain subjects embedded with laboratory-based activities. However, research on the benefits of positioning the practicals within the theory subject or developing them distinctly from the theory is largely absent. This report compared results in a physiology theory subject among three different cohorts of…

Findings are reported from a study which compared the effectiveness of specialized and general fifth-grade science teachers (N=86). A causal model, derived from path analysis, was constructed to explain the apparent lack of effect on student achievement of the superior preparation and instruction of specialized teachers.(IAH)
