The aim of this study is to determine the effect of variables such as gender, class and parental education level, family income level on motivation levels of students to learn science and do research, performance, communication, collaborative work and participation. The study group of the study was in the 2015-2016 academic year, public schools in…

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 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…

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…

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…

Learner and program control of content review within computer assisted instruction (CAI) were studied to determine their effects on the posttest performance and attitudes of eighth grade students. The science-related instructional treatments were completed by 98 students who were blocked by gender and reading ability and randomly assigned to…

Adjunct questions were inserted after each of 12 computer-animated graphics sequences shown to 160 eighth-grade science students. These sequences presented two relationships in a purely spatial fashion. Four randomly assigned treatment groups received questions targeting one of the two relationships (temperature or molecular motion) over all or…

This study investigated the effects of three instructional strategies and student entry characteristics on student engagement and the acquisition of skills necessary for the construction and interpretation of line graphs. The strategies examined were an activity-based approach, a written simulation-based approach, and a combination of activity-…

This study investigated the potential influence of female science teachers as sex role models for eighth-grade girls' science and engineering (SE) career interests. Subjects were 30 eighth-grade science teachers (14 men and 16 women) and their 1,937 eighth-grade students (992 girls and 945 boys). Using an SE career interest survey (CIS) developed…

Designed to evaluate the use of microcomputer-based labware (MBL) in junior high school science, the Computer as Lab Partner Project examined classroom experience of using MBL; system features used and curriculum designed; classroom procedures, processes, and interactions; gains and benefits of MBL use; and potential difficulties in MBL…

Most school curricula include the study of health as a separate subject or as part of science. Despite this, students often leave school without a clear understanding of many health concepts. This study investigated a group of grade eight and nine students' knowledge of personal health and physical fitness concepts and its relation to locus of…

Reports on student attitudes toward science-technology-society (STS) after visiting a science-technology museum and considers what variable factors of the visitation impacted these attitudes. Results indicated that significant differences in attitudes were present between visiting and nonvisiting students and between grade levels. (TW)

This study combines quantitative and ethnographic methods to analyze middle-school students' uses and understandings of microcomputers and videotex. As an experiment in teaching library research skills, 27 eighth graders were assigned to search an online encyclopedia in preparation for writing a science theme. The students' operational practices…

Asserts that students' opportunities to learn subjects can be organized into sequences that span grades and schools. Examines national patterns in opportunities for learning mathematics and science from grade 8 to grade 10. Finds that the level of mathematics in grade 8 is closely related to that taken in high school, but this is not true of…

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,…
