Discusses a three-week summer college honors course for talented high school juniors with three exams, lab six days a week, a research paper, field trips, and student panel discussions. Presents an overview of the course. Describes the lab which uses "E. coli" for DNA recombination. (MVL)

To improve elementary science instruction in rural and small schools, the University of Tennessee at Martin developed a successful research-based model for inservice teacher education that included teacher developed curricular materials, multidisciplinary content, hands-on science instruction, local team leadership development, and joint training…

Discusses ways in which children's language arts skills, cognitive knowledge, and emotional growth are developed when international children's literature is used in the teaching of a content area. A description of a unit of study includes activities and books that might be used in the study of nocturnal animals. (NH)

Investigated were the effects of interactive computer-generated homework on unit tests, a final examination, and a comprehensive test given near the end of a Physical Science I course. The results indicated that the use of the homework reduced the effectiveness of the American College Test scores as a predictor of course achievement. (YP)

Discusses the use of computers in the classroom, suggests visions of an educational future, and describes a project developed at the University of Maryland to examine the effects of computers on the college-level physics curriculum. Topics discussed include microcomputer-based laboratories, increased modeling power, and access to large databases.…

Discusses the need to encourage increasing numbers of persons to enter analytical chemistry, educate them thoroughly in basic chemical science, and expose them to the most modern methods and instrumentation. Examines some problems and several university's efforts to overcome them. (MVL)

Described is a university physics course bridging the gap between educational methodology, content, and applications of physics in identifying and resolving both societal and physical problems. Discussed are students' goals, instruction, and evaluation. Provides supporting texts list, a sample schedule, and sample ideas for independent…

Reports on a study which was conducted to provide a sample of biology teachers an opportunity to describe their experiences and opinions regarding the controversial issue of evolution and creation as it relates to teaching about the origins of life. Provides the objectives, sample selection, an analysis, and a conclusion. (RT)

Explains an activity that allows students to visualize antigen-antibody type reactions and learn about antibodies and antigens without performing blood typing tests. Provides directions for students and a comparison chart of a blood typing simulation with procedure which is based on the reactions of certain ionic solutions when mixed. (RT)

Follows the increase of the pH in a solution of vinegar during neutralization with commercial antacid tablets. Provided are background information, equipment details, procedures, and details of the data analysis. (MVL)

Discussed is a method to teach undergraduate students how to complete a conceptual design. Presents three tools to use: (1) how to use order-of-magnitude arguments to simplify problems, (2) how to derive design heuristics, and (3) how to decompose large problems into a set of small, simple problems. (Author/MVL)

Models which demonstrate the concept of moment of force in two- and three-dimensional cases and have been well received by students are described. Photographs and instructions for each model are provided. (MVL)

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)

Addresses whether or not science laboratory activities should become a thing of the past. Discusses the impact of the curriculum reforms of the 1960s and 1970s, physical restraints which cause teacher overload, rationale, and objectives of laboratory work. (RT)

Describes one successful secondary science model involving a child-centered plan of instruction that uses several nontest evaluation and documentation strategies to verify mastery of essential elements. (MS)
