This pilot study tested the hypothesis that the logical thinking skills of middle-grades students are enhanced by teaching them computer programming using the BASIC programming language. A quasi-experimental design was used with 36 students randomly selected and assigned to one of two treatment groups: 18 students received no instruction in…

Examines the line graphing ability of middle/high school students (N=625) to provide baseline data on the mastery of line graphing subskills. Results show that seventh- and eighth-grade students were less successful in graphing than high school students, suggesting that graphing skills should be introduced and emphasized in earlier grades.

Determined if the number of operational questions asked by fifth- and sixth-grade students (N=72) increased by teacher modeling or by practice at writing such questions. One finding is that students experiencing two types of teacher modeling asked more operational questions than students in a control group. (JN)

This study describes strategies fifth- and sixth-grade children used to solve the problem of determining how to control a "vehicle" they "drove" by pressing particular keys on a computer. The problem involves identifying or discovering a set of cause-effect relationships. (Author/JN)

Word association techniques were used to examine the growth of biological knowledge over a period of years, from fourth-grade to college students. Results were analyzed by classifying stimulus-response word pairs according to the nature of the relationship between the words in each pair. Three hypotheses were tested: (1) the proportion of enactive…

Provides guidelines for translating university science laboratories into middle school science activities. The need for guidelines is based on the authors' discovery that teachers teach what they were taught. Discusses six expected outcomes of middle school science activities: developing science concepts; practicing process skills; quantitative…

Investigated spatial thinking abilities of sixth- and tenth-grade students from two locales--a school on the Navajo reservation and schools in Mesa, Arizona. Overall findings support the contention that there were no substantial time delays or advances in development of selected spatial abilities of Navajo students compared to parallel non-Indian…

Fifth- and sixth-grade students (N=154) participated in a study which found that cooperative learning situations, compared to individualistic ones, promoted more positive cross-sex and cross-handicap relationships. It was also found that males achieved higher and had more positive attitudes toward science than did females. (Author/JN)

Examples of explanations students give during science lessons are used to demonstrate that there are a number of very different modes of explaining. In addition, it is suggested that the peculiarly scientific method of explanation is fraught with difficulties, some of which current learning theories may just be able to describe. Areas discussed…

Cognitive and affective outcomes of a class visit to a participatory science museum were examined by comparing responses of 416 fifth and sixth graders randomly assigned to four conditions (control, exhibit, lesson, exhibit followed by lesson) and two tests (verbal and visual). Results and implications for science education are presented.…

Students from 15 intact classes in grades 6 and 7 (N=142) from suburban schools in Perth, Australia, were used to investigate their time on task and achievement in process-oriented lessons. One finding noted is a positive relationship between achievement and student reasoning ability and engagement in planning and collecting tasks. (JN)

Conducted an ethnography to evaluate the usefulness of the notion of community of practice in classroom settings. Documents how collectively available knowledge of a classroom community was transformed as resources and practices were adopted by more and more members. Discusses implications for the organization of classroom environments that…

Student questioning within the Search, Solve, Create, and Share (SSCS) problem solving instructional model was investigated. The results suggest that the SSCS problem-solving instructional model increases student questioning in the presence of the teacher (n=22) when compared to a teacher-directed laboratory instructional model. The implications…

This study was part of a project to develop science and technology (STS) issue investigation and action materials with the potential for use across science and social studies classes at the secondary level. Special emphasis was given to learning teachers' perspectives on the development of a unit on the impact of pesticides on society. Seven areas…

This study examined the effect of formal and concrete instruction upon science achievement and intellectual development of sixth grade students. Formal instruction, which emphasized oral and written language, included lecture, discussion, oral quizzes, written assignments, reading assignments, films, film strips, written tests, and quizzes.…
