Presents an activity to articulate comparison of the hand and foot. Students carefully cut out corresponding hand/foot parts (carpals, tarsals, metacarpals, metatarsals, and phalanges) from enlarged diagrams and paste them on paper for comparative analysis. Sample student inferences and diagrams used for the activity are provided. (JN)

Compares the performance of ninth-grade students on 30 common test items given during the First (1970) and Second (1983) International Science Study, including differences related to sex. Findings, among others, show that overall, students in 1983 scored higher than their predecessors in 1970. (JN)

The level of meaning (membership, partial association, or generalization) that English-speaking (N=1635) and Hindi-speaking students (N=823) preferred when thinking about each of 16 key concept definitions associated with the theme "the nature of matter" was measured for each concept. Results and implications for science instruction are…

Reports a study which investigated the cross-cultural validity, reliability, and distinctiveness of the subscale structure of the Test of Science Related Attitudes (TOSRA). Results from tests of American high school students (N=336) indicated that the seven subscales were highly reliable, but that the discriminant validity was low. (ML)

Compares the professional need of science teachers across subject areas and countries by using the Science Teacher Inventory of Need. Reports the results and compares them with United States' research data. (YP)

Explores the nature of explanations used by 20 middle school science teachers utilizing the constant comparative analysis method in analyzing transcripts of classroom discourse. Discusses a subsuming categorical framework for the 10 types of explanations generated, along with examples of each type, namely: analogical, anthropomorphic, functional,…

Discusses some of the major research in science education published during the last 10 years in order to raise some of the methodological issues involved. Illustrates the progress that has been made along the path toward a science of teaching science. (CW)

Explores the rationale behind the importance of teaching young secondary school students how to look for correlation patterns. Describes two lessons that show how pupils can experience zero, positive, and negative correlation patterns between variables. Indicates the possible success of the Cognitive Acceleration through Science Education project.…

Compares performances of students on gas-law problems that require two distinct approaches, either the algorithmic technique or the conceptual gestalt. Indicates that student effectiveness is considerably different utilizing each approach and that training or experience with the algorithm process should not be expected to facilitate the…

Contrasts the traditional honors program and the Advanced Placement program of the College Entrance Examination Board using the self-reports of 155 high school science teachers experienced in both programs. Examines the perceived influences of each program format upon the use of basic teaching techniques, laboratory experiences, pacing of the…

In this study, American pre-service teachers' responses on Kimball's Nature of Science Survey (NOSS) were used as a basis for analyzing the sense of "the nature of science" held by a group of Nigerian pre-service science teachers. In comparing the responses it was apparent that the Nigerian students were much more inclined to see science…

This report summarizes the characteristics of physics education in 12 countries: Argentina; Brazil; Canada; Chile; Colombia; Costa Rica; Ecuador; Guatemala; Jamaica; Mexico; the United States; and Venezuela. An introductory chapter describes the goals of the Council on Inter-American Conferences on Physics Education, historical background,…

Compares models of the classroom dynamics for a traditional laboratory setting and a problem-solving-centered environment, both at the eighth grade science level. Descriptive data indicate no differences in the models, whereas path analyses suggest that, in the problem-solving model, student behaviors significantly correlate to lesson structure,…
