Discussed is the purpose of role playing in the classroom. Suggestions for preparing for role playing are enumerated. The advantages and rationale for role playing in the science classroom are stressed. (CW)

National Science Foundation support for instructional innovation in design curriculum is discussed. Programs that illustrate diverse approaches to teaching design are described. A list of programs given engineering curriculum development awards in 1988 and 1989 is provided. (CW)

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)

Extension activities involving the ballistic pendulum beyond its typical use in physics instruction are presented. The construction of apparatus, procedures, and probable results are discussed. (CW)

Classroom demonstrations of selected mechanical properties of polymers are described that can be used to make quantitative measurements. Stiffness, strength, and extensibility are mechanical properties used to distinguish one polymer from another. (KR)

The use of an olfactory acid-base indicator in titrations for visually impaired students is discussed. Potential olfactory indicators include eugenol, thymol, vanillin, and thiophenol. Titrations performed with each indicator with eugenol proved to be successful. (KR)

Included are the general guidelines, outline, a summary of major intermedia transport processes, model features, a discussion of multimedia exposure and health risk, and a list of 50 suggested references for this course. (CW)

Reviews current research in the application of the Neo-Piagetian theory of Pascual-Leone and shows how it provides the science teacher new implements. Hypothesizes that the role of the environment and creativity, if emphasized adequately, can help make science instruction more effective. (Contains 45 references.) (PR)

Describes problems with teaching embryology in the traditional manner. Presents a new approach where students prepare presentations, questions, and discussion topics. During laboratory periods, students conducted their own long-term research projects. (PR)

Describes a project to improve the science curricula and the science teaching skills of instructors in Houston-area two-year colleges in such a way that the program can be replicated in other locations. Two-year college faculty members were teamed with faculty from universities. (PR)

Describes an activity appropriate for college or high school students where they make hypotheses about prearranged patterns in a deck of playing cards. (PR)

Describes a one-week workshop for biology graduate students designed to persuade these future biology teachers of the importance of good teaching; inform them of the techniques, theories, and procedures that can improve instruction and learning; and train them in these techniques. Organization and preparation are emphasized as essential in any…

Describes relatively simple and inexpensive experiments for demonstrating the immune response to honeybee venom in the American cockroach, "Periplaneta americana." (PR)

Describes a technique to isolate unsheared bacterial DNA and subject it to restriction endonuclease enzyme digestion. (MDH)

Describes a program at Drew University, in which retired scientists receive offices, research space, and equipment in exchange for directing the research of advanced undergraduates. (PR)
