Explores the relationships between seventh-grade students' misconceptions of genetics and natural selection and four cognitive variables: reasoning ability; mental capacity; verbal intelligence; and cognitive style. Reports that only the reasoning ability was significantly related to the number of misconceptions. (Author/YP)

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…

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…

Reasoning abilities of Cypriot 12th graders in five forms of formal logical thought were studied in relation to academic achievement and gender differences. Results support proposals that suggest that there are specialized abilities dealing with specific domains of reality. The five reasoning modes were significant predictors of achievement. (SLD)

Contends that student success in introductory science courses at the college and university level depends on formal operational reasoning ability, size of working memory, and the degree of field independence. Reports the study findings related to cognitive predictor variables based on the testing of Venezuelan science majors (N=95). (ML)

Investigated were the relation between functional M-capacity and student performance in solving chemistry problems of increasing M-demand. Student performance decreased as the M-demand of the problems increased. (Author/YP)

A 1-year lag was found between the effect of an intervention intended to promote formal operational thinking in students initially 11 or 12 years of age and the appearance of substantial science achievement in the experimental groups. A one-year lag on cognitive development and an age/gender interaction were also reported. (Author/KR)

Attempts to show that not only can density be taught to lower ability pupils but that by doing so, there is the possibility of assisting pupils to develop their reasoning powers. Lists teaching activities that help in this process. (CW)

Five- to six-year-old children estimated the size of Euclidian objects using an addition rule of Height plus Width, rather than a multiplying rule. Within the framework of information integration theory, tested whether intensive handling of objects would facilitate shift from addition rule to multiplication rule. Found that following handling,…

Studies 94 undergraduate students in introductory statistics and computer science courses. Applies Formal Operations Reasoning Test (FORT) and Kolb's Learning Style Inventory (LSI). Finds that substantial numbers of students have not achieved the formal operation level of cognitive maturity. Emphasizes need to examine students learning style and…
