Describes an assignment in a graduate-level course in sedimentary-basin analysis that requires students to write a research-grant proposal. The assignment forces students to develop a topic suitable for original research. Each year 25 percent of the class turns these assignments into master's thesis projects and/or submits them as student grant…

Explored how elementary school children (n=267) "think" about science vocabulary through an examination of the organizational schemes children employ with science words. A common core of vocabulary was developed from textbooks. Students grouped the words and gave the group a name. One result indicated students had appropriate conceptual…

Describes an instructional program designed to promote scientific literacy among middle grade students. The program used a collaborative group instruction approach and focused on the development of tasks that provided students with opportunities to solve problems and to employ concepts useful to scientific problem solving. (PAM)

Reports a study (n=41) of the effectiveness of in-depth, conceptually integrated instruction delivered via a videodisc program in eliminating children's alternative frameworks in science. This curriculum, which did not directly address alternative frameworks during instruction, changed 92% of the alternative frameworks held by students to…

Through a review of the literature, looks at instructional and curricular issues related to the student-as-scientist model and the critical nature of the teacher's role in expanding school science activities to include this model. (SM)

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)
