Four reports are presented including "Alternative Approaches to Assessment of Practical Work in Science"; "Introducing Multicultural Science Teaching to a Secondary School"; "A Case Study on the Relative Performance of Boys and Girls in Chemistry Part II"; and "An INSET Technique--Developing a New Consensus." (CW)

Describes the effects of teacher subject-matter knowledge on classroom discourse at the level of individual utterances. Details analyses conducted in a year-long study of language in the classrooms of four new biology teachers. Among the findings are that these teachers talked more, asked more questions, and relied heavily on low cognitive level…

Explains how Darwin's observations and experiments can be used to show the true nature of science and good scientific methods. (PR)

Describes experiments by Thomas A. Knight on geotropism. These experiments took place about 200 years ago and used a centrifuge. (PR)

Discusses the necessity of effective AIDS/HIV education in the secondary schools, its inclusion in the biology curriculum, and methods of educating teachers concerning the topic. Provides recent data related to AIDS and proposes that science teacher stress abstinence and behavior modification as possible solutions. (MDH)

Describes using the common house plant, "Coleus blumei," to illustrate gravitropic effects, phototrophic effects, and hormonal effects in plants. (PR)

Provides reasons for pursuing interdisciplinary study, reviews past interdisciplinary efforts, presents in detail a course model, and summarizes student and faculty reaction. (PR)

Describes strategies that use trade books to teach science to primary students. Strategies include (1) developing concepts and vocabulary; (2) using concrete manipulatives to reinforce learning; (3) encouraging retelling; (4) developing class summaries; and (5) developing visual imagery. (MDH)

Describes a high school pilot program to meet California's science curriculum guidelines to adopt a Scope, Sequence and Coordination (SS&C) approach. The SS&C curriculum offers four science subjects for each year of high school. Concrete, phenomenological, and descriptive topics are covered during the early years and theoretical and…

Explains the origin and purpose of the National Science Education Standards. Defines what is meant by the term standards and describes the function of the National Science Education Standards as contributing to the development of a scientifically literate population. Contains 22 references. (DDR)

Outlines the development of a curriculum in molecular science that prepares those students who have a deep understanding of chemistry concepts and principles, have collaboration skills, are able to use modern technology, and can write about chemistry. (DDR)

Describes a course for non-chemistry majors that uses a distance-education format. Utilizes lectures on videotape, electronic communication, thematic research assignments, and take-home lab projects. (DDR)

Reports on a study to determine whether the presence of coordinate axes in a test of spatial-visualization ability affects scores and response times on a mental-rotations task for students enrolled in undergraduate introductory graphic communications classes. Based on Pavios's dual-coding theory. Contains 36 references. (DDR)

Reports on a project that attempts to inform faculty of female-friendly changes in curriculum content and pedagogy derived from research in women's and ethnic studies. Supports the hypothesis that more inclusionary techniques help reverse the trend of increasing student attrition. (DDR)

Focuses on an extended learning experience with worms as the main topic in which students collect and organize information and choose an experimental question. Based on the constructivist theory of learning. Contains 17 references. (DDR)
