Reports a study of 922 college students that classified the students based on performance on formal operational reasoning tasks. Students were also administered seven logic tasks. Response patterns were analyzed and found to be similar to patterns derived from the multiple-hypothesis theory of advanced scientific reasoning and different from those…

This article reviews Piagetian theory on formal operational thought, the relationship of psychometric intelligence and formal operational thought, the development of formal operational thought in gifted children, problems encountered with Piagetian theory and attempts to modify it, and implications of the post-Piagetian perspective for education…

A nonequivalent control group design study, with a math unit on ratio and proportion as the treatment, was conducted to examine the validity of some written tasks as a measure of formal reasoning. Subjects in the study were 68 fifth grade students who enrolled in two classes in a small urban school. The experimental group learned a 12-lesson math…

Gifted and highly gifted girls in grades four to six were given Piagetian-type manipulative problem-solving tasks reflecting formal operations. Although Flavell suggested that a chronological age of 10 years was necessary for successful completion of these tasks, time allowed was a more valid predictor. (LMO)

Provides examples of if-then and combinatorial reasoning situations that have proved successful with college students and can be used with secondary school students. Proposes that practice with these problem solving processes can eliminate the need to memorize formulas that students may not understand. (ML)

Presented is a study in which students' intellectual reasoning development was evaluated following instruction that emphasized formal operations in a traditional lecture format. Results indicated that formal-operational students had significantly more success in the three reasoning areas than transitional students and transitional students had…

Studied children's transitive inference where representation of premises provided contradictory information depending on position of two elements in a A, B, C series. Eight-year olds did significantly better on the more complex problems than did six-year olds, suggesting the presence of a developmental sequence of algorithms that enable children…

Seventeen college undergraduates, possessing either basic or consolidated formal operations, received eight weeks of interpersonal skills training and pre- and posttraining assessments of social perspective taking and moral reasoning. Gains in moral reasoning were related to subjects' possessing prerequisite cognitive and perspective-taking…

Examined the effect of mothers' familiarity with a formal operations task on performance and monitoring of a cognitive task with their children and on the child's later performance alone. The task-familiar mothers elicted higher level strategies during problem solving and allowed their children to participate more than did the other mothers; their…

Assessed was the level of thinking of 140 students who had been placed in developmental algebra as entering college freshmen. Scores on the Group Assessment of Logical Thinking, Scholastic Aptitude Tests, college placement tests; high school grade point average, and developmental algebra final grade were analyzed. Group characteristics are…

Examines the relationship between adolescent egocentrism and postformal thinking in 163 college undergraduates. Uses the Imaginary Audience Scale and the Social Paradigm Belief Inventory to evaluate participants. Results indicate that females have higher levels of adolescent egocentrism than do males. (Author/GCP)

Describes a science experiment that gives students experiences with the float-sink phenomena and allows them to practice what Piaget called formal operational thinking. The goal of the experiment is to determine some of the variables responsible for cans of soda sinking or floating. (TJQ)

Previous investigations on Piagetian cognitive levels among college students both within and across academic disciplines have not addressed the issue of possible differences in cognitive levels between traditional undergraduates and older returning students. Piagetian cognitive levels were studied among traditional- and nontraditional-age college…

This study examines the developmental status of young mothers' social and logical-physical reasoning in relation to the characteristics of their interactions with their infants. A total of 36 mothers 15 to 21 years of age and their 4-month-old infants were videotaped in their homes during play, infant teaching, and bathing. Selman's "concepts…

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.…
