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…

This paper is concerned with the kind of messages about science conveyed to 23 young gifted children enrolled at the McGill Summer School for Gifted and Talented Children in Montreal while utilizing a particular teaching model. Five science lessons were analyzed by applying a newly developed scheme to classroom interactions. The scheme helps to…

Clinical interviews were conducted with 25 seventh- and eighth-grade students to determine: (1) the extent to which they could produce correct graphical representations of familiar situations; (2) to what extent they could infer relationships from graphs; (3) what are the most commonly held graphing misconceptions and how stable they are; and (4)…

Analyzes three approaches (physical, mental, combined practice) to improving freshman chemistry psychomotor laboratory skills. Although no significant differences were found between treatments, there were significant differences when each was compared to the control sections. Mental practice appears to offer an efficient methods for reinforcement…

Reports efforts and results associated with the development and validation of a test of graphing skills for grade seven through twelve science students. Concludes that the Test of Graphing in Science (TOGS) is a valid and reliable instrument. Also discusses TOGS value to the teacher and educational researcher. (ML)

Computerized science simulations were employed by high school biology students in an attempt to enhance their problem-solving skills. The simulations were administered under unguided (discovery learning) and guided (guided discovery learning) conditions while a control group received no simulations. To ascertain the effectiveness of the…

Presents a comparative analysis of the psychometric properties of three group tests of logical thinking used in science education research. Findings dealing with Longeot's Test of Logical Thinking, Lawson's Test of Formal Reasoning, and Tobin and Capie's Test of Logical Thinking demonstrate a lack of concurrent validity. Includes recommendations.…

Investigated secondary-level students' (N=66) understanding of three-dimensional structures in biology. Results suggest that student performance is highly correlated with age, scientific ability, and sex. Suggestions for instructional improvement in spatial relationships are offered. (ML)

Determined whether significant differences exist in cognitive achievement and in the level of acquisition of practical skills among ninth-grade students (N=1025) in cooperative, competitive, and individualistic learning conditions in science laboratories. Results are discussed in terms of their implications for more productive science laboratory…

Examined the effectiveness of cooperative, competitive, and individualistic interaction patterns in promoting acquisition of science process skills during biology laboratory activities. Results (from 720 secondary students--352 girls and 368 boys) show that competitive interaction was superior to cooperative and individualistic interaction…

This study compared the process skill achievement of students (N=107) completing traditional laboratory exercises with students (N=127) not only completing the same exercises but also receiving instruction in such integrated process skills as identifying variables and stating hypotheses. The relationships among process skill achievement, cognitive…

Defies the assumption that laboratory teaching skills are gained by preservice secondary science education majors through their undergraduate science programs, and presents expertise areas which every teacher should possess. Outlines activities for each skill which can become part of a methods course under the direction of science educators. (DH)

The interaction effect between two process skills (application and interpretation) and two task contexts (scientific and everyday) was investigated. Korean students (n=255), ages 13 and 15, were the subjects of this study. Results reveal that there was an apparent interaction between process skills and contexts. Sex-skill interaction and…

Commissioned for use during the design phase of the "Skills Essential to Learning" (SEL) video project, this concept paper makes a number of suggestions for facilitating effective scientific learning. These include: (1) establishing a positive climate for science learning in which the student can ask and pursue questions, change routes,…

Students' attitudes, expectations, and opinions about a desirable preparatory preacademic program were investigated before and after 1 year of science studies in the Preacademic School (PAS) of the Hebrew University. A questionnaire was pre- and post-administered to 150 PAS students (70 percent of whom were classified as academically disadvantaged…
