Describes a method of demonstration and modeling used to improve the science teaching ability of eight elementary teachers. Designed to increase teachers' knowledge of physics, the course documented changes in the teachers' knowledge and practice. Results are discussed in relation to case methods and cognitive-apprenticeship models of training.…

Programs designed to enable Australian aborigines who had not successfully completed high school to qualify for science- and mathematics-related courses in higher education emphasize diagnostic testing, individualized instruction, short-term goals, and learner independence. Tutors have instructional, management, and support roles. Some early…

Reports results of the Second International Science Study concerning achievement in physics of U.S. high school students. Makes comparisons between students of 13 other countries and U.S. students, between first- and second-year U.S. physics students, and between U.S. students tested in the mid-1980s and those tested in 1970. (MDH)

Author describes use of writing assignments to help ninth grade students learn earth science and increase their interest in it. Presents advice for both formal writing assignments (laboratory reports and library-research papers) and informal assignments (learning logs or journals and role writing). Frequent review and encouragement with lots of…

The author describes her use of writing assignments, small-group discussions, note-taking strategies (learning logs), and professional simulations in an introductory geology course. The learning log process consists of note taking on one side of a divided page. After taking notes, students review the notes and record their questions, reactions,…

Explains how students can learn basic petrographic techniques by using a thin-section collection prepared from the rock units in a geological area under study. Each student defines a particular problem to investigate and is responsible for collecting samples in the field, making additional thin sections, and preparing formal written and oral…

Describes a study of undergraduates in a biology course for nonmajors that examined the effects of four methods of immediate corrective feedback during computer-based instruction (CBI). The relationship between types of corrective feedback and types of errors made by learners during CBI and during a later retention test is also examined. (33…

Reports results of an 18-item questionnaire mailed to all 730 school board presidents in the state of Ohio. Among the findings are that 52.8% of the presidents thought that "creation science" and 67.3% thought that evolution should be favorably taught in public schools. Only 13.7% thought that creation science was currently taught in…

Argues the urgency associated with school reform must be tempered by the fact that much reform is being guided by the rhetoric of a conservative ideology. Urges science educators to resist conservative ideological rhetoric that seeks to sway the masses. Science education must move beyond the positivistic, ahistorical, and depoliticized orientation…

Presents a study to develop and partially validate an instrument to measure the self-efficacy beliefs of teachers related to utilizing microcomputers in science instruction. The resulting instrument contained two subscales: the Outcome Expectancy and Personal Self Efficacy Scales. Appendices include the instrument and scoring instructions. (17…

Presents research data that demonstrates current disparities in science proficiency among subgroups defined by gender and race. Discusses differences in achievement, science experiences out of school, and academic support. Presents seven guidelines for structuring science activities that motivate and respond to the interests of all students. (19…

This study examined the relationship that exists between high school teachers' (n=25) understanding of the Piagetian developmental model of intelligence; its inherent teaching procedure, the learning cycle, and classroom teaching practices. The teachers who exhibited a sound understanding of the model were more likely to effectively implement the…

Classroom interactions were examined for gender differences that may contribute to the underrepresentation of women in physics and engineering courses and subsequent careers. (PR)

Selective illustrative examples of students' learning difficulties and misconceptions in first-year general and organic chemistry are presented in the students' terms, followed by strategies the author uses to overcome the difficulties. Suggests that student misconceptions in first-year chemistry are not interrelated logically and are not prone to…

Provides examples of how concept mapping can be used to help overcome misconceptions in college chemistry. (PR)
