Around the world, there have been curricula reforms involving the incorporation of the inquiry-based teaching and learning strategy in secondary school science education in general and in practical work in particular. Research in inquiry-based practical work (IBPW) has focused, for example, on aspects of the strategy itself, on teacher…

Although the practice of giving examples is central to the effective teaching and learning of science, it has been the object of little educational research. The present study attends to this issue by systematically examining the exemplification practices of a university professor and his students' learning experiences during a biology lecture on…

This study investigated the effectiveness of a web-based learning environment in enhancing 10th grade high-school students' understanding of the concept of "chemical bonding". Two groups participated in this study: an experimental group (N = 161) and a comparison one (N = 93). The teachers in the experimental group were asked to implement four…

Reports results of a survey developed to assess the use of learner-centered techniques in undergraduate science and mathematics classrooms. Reveals that learner-centered techniques are used infrequently, but when used, they are applied to all aspects of teaching. Suggests that federal funding has been slightly effective in promoting its use. (KHR)

This study investigates the understanding of 18 first-year undergraduate students when simultaneously presented with two contrasting dynamical situations: the idealized (without air resistance) and real-world cases of balls being dropped or thrown. Previous work has shown that getting students to recognize flaws in their mental models helps them…

This project consisted of a meta-analysis of U.S. research published from 1980 to 2004 on the effect of specific science teaching strategies on student achievement. The six phases of the project included study acquisition, study coding, determination of intercoder objectivity, establishing criteria for inclusion of studies, computation of effect…

Explores the differences between deep and surface approaches to learning science. Findings indicate that the deep-surface learning differences fall into five categories: (1) generative thinking; (2) nature of explanations; (3) asking questions; (4) metacognitive activity; and (5) approach to tasks. Suggests that teachers can encourage a deep…

Examines the relationship between high school students' perceptions of their science learning environments and their motivation, learning strategies, and achievement. Discusses the focus of shared perceptions and instruction and indicates that shared perceptions focused on understanding and independent thinking positively predicted students'…

Describes a study designed to determine whether the Biology Critical Thinking (BCT) project (which incorporates activities for developing specific critical thinking skills into the biology curriculum) enhances critical thinking skills and how it affects students' biological knowledge and classroom learning environment. Results indicate that BCT…

A control group of 40 eighth graders completed a unit on elements and compounds. An experimental group of 42 completed concept maps on the same topic. Results of a one-tailed T test demonstrated the usefulness of concept maps as advance organizers. (KR)

Discussed is the relationship of concept-mapping by students to the meaningful learning of genetics and ecological concepts. The implications of these results for teacher education in biology are addressed. (KR)

Describes the use of an intervention stressing the metacognitive, regulatory, and strategic aspects of knowledge co-construction. Finds that eighth grade students who received the intervention gained in metacognitive knowledge about collaborative reasoning and ability to articulate their collaborative reasoning processes compared to students in…

Presents data indicating that learning can be enhanced when information is presented that illustrates how science information can be used to solve problems. The experiments showed positive results through use of video-based macro-contexts. (ML)

Presents a study involving students (n=46) enrolled in an introductory physics course designed to describe and understand students' experimenting and problem-solving strategies in a constructivist learning environment. Concludes that students should be provided with problem-rich learning environments in which they learn to investigate phenomena of…

Presents the focus of this theme issue that is devoted to examining critical, feminist, and poststructural theories and the implications these theories have for considering the ideal, a science education for all children. (PVD)
