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)

Describes Pedagogical Content Knowledge and focuses on the empirical research directly concerned with the relationship between science teachers' subject matter knowledge or structures and actual classroom practice. Concludes there is little evidence that a relationship exists. (PR)

Reports an instructional application of a theory of analogical reasoning. Uses the grinding of a sugar cube as an explanatory-predictive analogy for state transitions of water as a stimulus for promoting associations with other appropriate experiences in elementary school students. (PR)

Explores the use of narrative as a vehicle for sharing, communicating, and understanding personal experience. Argues that the narrative is a useful form of expression that is too often neglected in science education. Through stories students may begin to more successfully see the subtle dimensions of science and understand the ways in which…

Proposes methods by which laboratory practical exams may be structured to assess outcomes from laboratory instruction. Presents eight general considerations for writing and using practical exams. Describes four example laboratory exams involving a box camera, circuit boxes, floating objects, and light. (MDH)

Investigated the effects of studying an ecological system via computer simulation on 14- and 15-year-old students' (n=9) abilities to pose hypotheses; control and manipulate variables; and learn via icon, graph, and table display formats. Working with a simulation encouraged students to think hypothetically and test their hypotheses by controlling…

Presents two activities for introducing the topic of carbon dioxide: (1) Investigating Some Properties of Carbon Dioxide and (2) Building a Carbon Dioxide Generator. (PR)

Describes a class activity in which New York City high school environmental science students take a field trip to visit an active sewage treatment facility and landfill operation. (MDH)
