Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory…

Concept-map construction was tested as a means of increasing the conceptual learning of first-year, non-major college chemistry students (n=32). No significant differences between the control (essay-writing) and treatment (concept-map-constructing) groups were found on post-lab multiple-choice achievement tests. Interviews with students indicated…

An interactive computer/videodisc learning approach to the conventional laboratory approach for learning biology concepts and science process skills were compared. The two approaches appear equivalent when evaluated by traditional learning outcomes, but the interactive videodisc strategy was significantly more time efficient than a traditional…

Identifies and describes the differences in the problem-solving methods used by faculty teaching introductory chemistry and students enrolled in an introductory chemistry course. Results indicate that students correctly solve algorithmic-mode problems more frequently. Contains 33 references. (DDR)

The use of inquiry-based laboratory in college science classes is on the rise. This study investigated how five nonmajor biology students learned from an inquiry-based laboratory experience. Using interpretive data analysis, the five students' conceptual ecologies, learning beliefs, and science epistemologies were explored. Findings indicated that…

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

Teaching strategies associated with a conceptual change model of science teaching were examined in a study of seventh-grade life science teachers (n=13). Greater use of conceptual change teaching strategies was associated with use of the special instructional materials, not with the training. Students in classes where teachers were provided with…

Reports a study (n=27) concerning the knowledge about image formation exhibited by students following instruction in geometrical optics in an activity-based college physics course for prospective elementary teachers. Student diagrams and verbal comments indicate their knowledge can be described as an intermediate state: a hybridization of…
