Summarizes research on inquiry and investigative strategies for teaching laboratory science. Concludes that meaningful laboratory instruction is distinguished by: student engagement in science inquiry processes, student manipulation of experimental materials, and the experiential teaching of specific scientific concepts. (RT)

Speculative philosophical methodology was used to generate ideas about ways science teachers might help students recognize and unlearn erroneous notions about science and replace them with sound new science concepts without lessening students' intellectual self-confidence or alienating their receptivity to further science learning. The research…

The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an…

Much of the focus in science education has been on the theoretical constructs and practical implications of conceptual change. History of science, cognitive theory, and alternative conceptions have been used as backdrops for the study of the child's conceptual movement away from naive beliefs about scientific phenomena. In this study, conceptual…

This study explores general-chemistry instructors' awareness of and ability to identify and address common student learning obstacles in chemical equilibrium. Reported instructor strategies directed at remediating student alternate conceptions were investigated and compared with successful, literature-based conceptual change methods. Fifty-two…

In this study 34 spontaneous analogies produced by 16 college freshmen while solving qualitative physics problems are analyzed. A number of the analogies were invalid in the sense that they led to an incorrect answer from the physicist's point of view. However, many were valid, and a few were powerful in the sense that they seemed not only to help…

This paper, designed to be used in conjunction with a video-tape developed by the Learning in Science Project (Primary)--LISP(P)--shows excerpts from some of the interview schedules used to examine children's ideas about floating and sinking. These interviews involved the use of "interview-about-instances" (IAI) cards (included in an…

This study investigated the meanings and ideas held and questions asked by children (ages 7-14) about floating and sinking (in water). Data were collected from interviews using "interview-about-instances" (IAI) cards (included in an appendix) and 10 objects which either floated or sank. Additional data were collected from classroom…

Discussed is the philosophy of the educational purpose of science education, the science involved, and the relationships of students and learning and students and content. A list of 14 references is included. (CW)

Reports on the assessment of student thinking in the area of commitment to the laws of conservation of matter and energy during a study of conceptual change among introductory chemistry students. States four conditions upon which strategies for conceptual change are based. (RT)

Two booklets were developed by the Learning in Science Project (Primary)--LISP(P)--to help teachers adopt an approach to primary science teaching which would enhance children's understanding of floating and sinking. Both booklets were designed to enable teachers to reconceptualize their teaching task from activity-driven, didactic teaching to…

The Scientific Theory and Method Project (STAMPS) is concerned with students' understanding of two areas of science in secondary schools. One is understanding what a scientific theory is, and the other is understanding the methods used in conducting scientific research. In the science curriculum these topics are often described as the process of…

This paper is a summary of much of the available research on college science laboratory instruction of the past decade with a focus on the effects of specific laboratory teaching strategies upon student learning outcomes. Some tentative interpretations from a review of the literature found are: (1) inquiry or investigative approaches in college…

The Educational Technology Center (ETC) has devoted the last five years to studying ways of using the computer and other information technologies to teach understanding in science, mathematics, and computing in the nation's elementary and secondary schools. The Center's research has focused on targets of difficulty, topics and concepts that are…
