Reports a study involving interviews with 20 physics teachers to determine their awareness of student alternate conceptions in the areas of force and gravity. (PR)

Outlines 39 physics demonstrations that utilize simple objects such as coffee and soda cans to illustrate scientific concepts. (12 references) (MDH)

Course selection of 795 gifted adolescents in a summer residential program differed along traditional gender lines in mathematics, science, and writing/literature. Girls and boys performed equally well in all types of classes; main effects in achievement and motivation were found only for type of class. The Scholastic Aptitude Test served as a…

Studies the simple dynamical system of the pendulum and the chaotic behavior that occurs when the pendulum is both damped and driven. Provides an algorithm and BASIC program for the numerical solution to the differential equations encountered in the discussion. (MDH)

Describes the use of concept mapping (CM) in design, instruction, and assessment related to microbiology lessons prepared for high school students in Israel. Indicates that students utilizing CM displayed an overall, higher achievement gain than students in traditional classes. Recognizes that some teachers did not thoroughly exploit the potential…

Presents a simple mathematical model in which resultant speed is the sum or difference between wind speed and runner speed and a more complex model that assumes that only a proportion of the wind's speed affects one's running speed to describe the time difference between running with and without wind. (MDH)

Provides nine fully developed library media activities designed to be used with specific curriculum units in health, music, reading and language arts, science, and social studies. Library media skills objectives, curriculum objectives, grade levels, instructional roles, activity and procedures for completion, evaluation, and follow-up are…

Uses three methods to analyze the intended curriculum in countries participating in the Third International Mathematics and Science Study (TIMSS). Explains the use of Topic Trace Mapping as a tool to examine the issue of depth versus breadth in the curriculum. Includes three figures illustrating the results of Topic Trace Mapping. (CFR)

Provides fully developed library media activities that are designed to be used with specific curriculum units. Highlights include elementary school activities for reading and language arts (using the "World Almanac," identifying a story's sequence of events, and using autobiographies); science (causes of wind and learning about…

The development of an instructional model based on a learning cycle including correlation, analysis, and generalization (CAG) is described. A module developed for heat and temperature was administered to test its effects by comparing its use with the same unit in the New Physical Science Curriculum (NPSC). The methodology, results, and discussion…

Effects of animated presentations and practice were studied in a computer-based science lesson involving 55 fourth graders and 64 fifth graders. Results suggest that animated graphics can promote learning, and they demonstrate successful application of interactive graphics in the design of cognitively based practice activities. (SLD)

Scientific and everyday knowledge domains are compared so as to reveal the distinctive differences between their goals and the cognitive processes used to attain them. The main goals, working goals, learning difficulties, knowledge structure, concept specification, knowledge organization, role of school science, program-solving instruction, formal…

Author describes how 22 first-year high school students became politically active concerning coastal-zone management and wetlands protection. Students translated regulations of the Maine Department of Environmental Protection into plain English. Students wrote their opinions in a concise manner and appeared at a board meeting to influence its…

Describes an approach to introductory geology that requires students to go into the field to make observations, collect and analyze data, synthesize those data, and hypothesize about inferred geologic relationships. The product of these laboratories is a paper that requires students to test their hypothesis using specific examples from the data.…

Author describes an individual research project involving digital modeling of graded river profiles as part of a sophomore-level geomorphology class. The three-week project gives students the opportunity to choose research topics, design experiments to test ideas, interpret results, and write a research report. (PR)
