Gives a rationale for, and benefits of, having preservice science teachers conduct a science exhibition for high school students and teachers. Provides organizational hints and recommendations. (WRM)

Develops a history and philosophy of science framework based on a rational reconstruction of experimental observations that led to the Millikan-Ehrenhaft controversy, and evaluates 31 chemistry books for coverage of the controversy. Finds that most books lacked a history and philosophy of science perspective and did not adequately address several…

Describes a constructivist chemistry laboratory approach based on students' personal experiences where students had the opportunity to develop their own experimental processes. Points out both the fruitfulness and difficulties of using a graduate student as a teaching assistant. (YDS)

Explains why it is important for chemistry educators to know about metacognition, provides some examples to illustrate main points, and discusses some instructional tools that have been employed to promote metacognition in introductory science courses. (Contains over 50 references.) (WRM)

Presents a project in which students create a chemistry resources World Wide Web page. Responds to the goal of applying new computer technology to student learning in a meaningful way. Emphasizes the role of planning and preparation in student projects. (DDR)

Provides an activity in which students create small classroom factories and investigate several aspects of production including design, engineering, quality control, waste management, packaging, shipment, and communication. (DDR)

Student-led workshops are helping undergraduate students learn from each other as they tackle organic chemistry. Each week, small groups brainstorm tough problems in sessions guided by upper-class students who have taken and passed the course. Debating and discussing chemistry problems with peers engages students with the material and boosts…

Presents an exercise in which an eighth-grade science teacher decorated the classroom with a periodic table of students. Student photographs were arranged according to similarities into vertical columns. Students were each assigned an atomic number according to their placement in the table. The table is then used to teach students about…

Outlines the development of a kinetic study using the enzyme Lactaid to hydrolyze the synthetic substrate of lactose into an undergraduate laboratory experiment. Provides students with experience doing order-of-magnitude estimates. (DDR)

Reconstructs students' and teachers' understanding of the structure of the atom based on a framework characterized by considering the history of science as competing research programs and by believing that some great scientific research programs progress on inconsistent foundations. Contains 107 references. (DDR)

Explores the interrelationships between students' general science achievement, scientific epistemological beliefs, and cognitive structure outcomes derived from instruction of basic atomic theory. Contains 19 references. (DDR)

Presents results from a study of the conceptions of chemical reactions held by middle school students, high school students, and general chemistry students at the university level. Results suggest that very few students understand what a chemical reaction is. Contains 19 references. (DDR)

Describes the development of a semester-long course that addresses issues of scientific integrity in a practical way as they arise in the daily lives of working scientists. Shares the topical organization of the course and other details. (DDR)

Explains how population growth can be used to illustrate the concepts of chemical kinetics. Provides an illustration of how one can use concepts and mathematics to take information that is known and obtain a result that is not initially obvious. (DDR)

Examines student success in a freshman chemistry course that involves students who are at risk of failure. (Contains 14 references.) (YDS)
