Describes a case study of an advanced physics class that analyzes the implications of using computerized journalizing. Reports that this technique provides a vehicle for students and teachers to make their knowledge public, builds an atmosphere for valuing the conceptual understanding of others, and mediates an ongoing dialog between the…

Presents the following activities for teaching elementary students about the metric system: Metric Soda Fountain, Metric Meals, Metric Moola, and Metric Golf. (PR)

Botany meets computer science in this activity, which challenges students to create a computerized seed catalog. Class members work together to develop a database of plants, much like the major seed companies do. (PR)

Describes an intelligent tutoring system designed to help students remedy misconceptions of physics concepts based on a teaching strategy called bridging analogies. Highlights include tutoring strategies; misconceptions in science education; the example situation network; confidence checking; formative evaluation with college students, including…

Although many students complain that the research-and-write about a favorite scientist is boring, a sixth-grade teacher offers successful alternatives. Through creative writing and hands-on activities, this assignment is made meaningful and fun for students. Excerpts from completed projects and evaluation tips are presented throughout the article.…

Details two studies: (1) Study A describes a close replication of a Bishop and Anderson study (1990) using the same conceptual-change teaching module to teach a unit on evolution to nonmajor biology students; and (2) Study B used high school students, and the instruction was based on the inquiry approach to science.

The use of cellular automata to analyze several pre-Socratic hypotheses about the evolution of the physical world is discussed. These hypotheses combine characteristics of both rigorous and metaphoric language. Since the computer demands explicit instructions for each step in the evolution of the automaton, such models can reveal conceptual…

Identifies the attitudes of secondary school students toward several science-related topical areas (i.e., nuclear energy, environmental issues, energy concepts, science concepts, space exploration, and metrication) for the purpose of enhancing students' attitudinal development toward science-related topical areas. Discusses respondents attitude…

Describes a qualitative study in which eight elementary school teachers read research articles in children's science and were interviewed. Results fall in three categories: comments relating to the teachers' need to verify the findings of research reports, expressions of self-doubts and questions raised as teachers read the articles, and…

Calculates an approximation to Avagadro's number for one mole of water by assuming the mole to be in cubical form and then halving the cube three times, thereby doubling the surface area of the original cube. The calculations are derived from the work necessary to perform these divisions. Presents calculated values for several liquids. (MDH)

Analyzes problems with traditional teacher education, reviews the basic elements of the constructivist learning views, and discusses the advantages of a constructivist approach to science teacher education. (PR)

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…

Seventh-grade students (n=397) were studied to determine the effect on immediate achievement and retention of a unit designed to promote the development of estimating skills involved in metric measuring. Identical metric instruction was used with the exception of activities in estimation for the treatment group. The treatment group retained…

This study sought to find out whether concept mapping reduces anxiety and thereby enhances achievement in biology. A total of 51 grade-10 students participated in the experiment. Findings indicate concept mapping is significantly more effective than traditional teaching in enhancing learning in biology and reducing student anxiety toward biology.…
