Concepts used by two classes of grade eight students, one advanced and the other average, to explain the changes that occur when water is heated to boiling are presented. Little difference was found between groups in terms of the personal misconceptions used to explain boiling. The changes that take place in conceptual knowledge immediately after…

Determined how 430 eighth-grade students perceived science teaching as a career. One area investigated was the relationship between student ratings of science teaching as a career and such variables as sex, race, age, educational aspirations, and mother's/father's education and job type. (JN)

This research explores the moment-by-moment understanding students exhibit in the learning of a non-physical science domain--the human circulatory system. The goal was to understand how students learn by capturing the nature of their initial mental models (naive conceptions), and by seeing how new information gets assimilated into their mental…

This paper presents a literature review related to the time spent teaching science and a study designed to test the hypothesis that student achievement in science is related to classroom hours devoted to science instruction. The study involved testing two groups of eighth grade earth science students (N=200) over instructional material presented…

The conceptual frameworks of Thai children (n=48) related to causes of health and sickness were analyzed using the "Interview-about-Instances" and the "Conceptual Profile Inventory" techniques. The results indicate that Thai schoolchildren hold considerable personal knowledge about the causes of health and sickness that does…

A multiple-group, single-intervention intensive time-series design was used to examine the achievement of an abstract concept, plate tectonics, of students grouped on the basis of cognitive tendency. Two questions were addressed: (1) How do daily achievement patterns differ between formal and concrete cognitive tendency groups when learning an…

This research evaluated the desirability of science teaching as a career as rated by eighth grade students. An instrument was developed on which respondents placed their own choice of best and worst possible careers as endpoints on a 10 point scale. Forty-five additional careers, including careers in science teaching, science, and teaching of…

The research reported in this study was done to evaluate the understandings developed by students who meet science concepts through a textbook. Findings indicated that concrete concepts were better understood by eighth grade students than formal concepts and that students achieved some understanding of some formal concepts. (CW)

Results of this study indicate that students' (N=155) self-concepts and gender role perceptions were related to both achievement and attitudes toward science, but more related to attitudes than achievement. In addition, these relationships became more pronounced for students as they matured from seventh to eighth graders. (Author/JN)

Examined the relationship of attitude toward science, spatial ability, mathematical ability, and scientific personality (measured by the Myers-Briggs Type Indicator) on the achievement of eighth-grade students (N=98). One finding noted is that males and females with science grades of C or D had the most characteristics not associated with science.…

Investigated differences between middle school and junior high instructional strategies and the effects on adolescent attitude toward science in school and science achievement (n=570) and evaluated variations within grade level, gender, race, general ability, and socioeconomic group. Discusses results in terms of effectively implementing changes…

This paper reports the results of a longitudinal study of the relationship between affect and achievement in high school science. The conceptual model for science-related affect proposes that students' enjoyment in, and enthusiasm for science are determined by their perceptions of their past performance in science, their expected future…

Describes study of eighth grade students conducted to test the effectiveness of mnemonic techniques to recall attributes of minerals. Results indicate that mnemonic instruction, when accompanied by experimentor-provided keywords and mnemonic illustrations, produced superior recall on both immediate and delayed performance tests. (Author/LRW)

This study reports the application to classroom dialogue of the Thematic and Structural Analysis (TSA) Technique which has been used previously in the analysis of text materials. The TSA Technique identifies themes (word clusters) and their structural relationship throughout sequentially organized material. Dialogues from four Year 8 science…

The effects of using a microcomputer for electronic research on the achievement and attitudes of eighth-grade boys and girls (N=247) were investigated. The study analyzed three dimensions of student themes, two sets of computer achievement measures, and three attitudinal dimensions for each of three treatment groups. Results showed no unpredicted…
