Determined is the logical reasoning necessary to construct line graphs including a straight line with a positive or negative slope and an exponentially increasing curve. The responses of subjects (grades 6-12) were classified into one of nine categories fitting with Piagetian operational structures. (Author/YP)

Investigates the effect that manipulation of the extent of formal reasoning required for solving chemistry problems has upon student performance, and presents a cognitive model for the qualitative analysis of that effect. Concludes that the developmental level of students is the most important predictor of problem-solving success given significant…

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.…

Research focused on two factors that may be influencing females in choice of careers. Factors are role-specific self-concept in science and self-perception in terms of stereotypical masculine and feminine characteristics. Logical ability and mathematics and science courses were also examined as factors in career choice. Results of data for 177…

Examines the hypothesis that there are preliminary stages in problem solving that are often neglected in teaching chemistry. Discusses correlations calculated between the student's ability to handle disembedding and cognitive restructuring tasks in the spatial domain and ability to solve chemistry problems. (TW)

Examines the influence of both locus of control and three instructional strategies to foster an understanding of the nature of science. Reports that the nature of science was most predictable for a separate process/content/teaching methods and logical thinking ability was the best predictor of the nature of science. (Author/YP)
