Three studies investigate the role of competence factors (defined as acquisition of Piagetian formal reasoning) and performance factors (defined as influences from content and expectations) with respect to adolescents' reasoning about advertisements reporting product tests. (Author/MP)

The present study investigated: (a) the relationship between IQ test scores and ability to follow specific instructions for solving matrices; and (b) the relationship between IQ test scores and the ability to follow strategy instructions for solving matrices. Findings from this investigation may clarify the relationship between intelligence and…

Gender differences in predicting displaced volume did not reflect gender differences in spatial ability, field-dependence-independence, or Piagetian formal reasoning. In addition, gender differences were not accounted for by science and math course-taking experience. (Author/PN)

To investigate the role expectation based rules governing formal reasoning performance, a battery of group and individual aptitude measures and formal reasoning tests were administered to 17-year-olds. Individual differences in usage of these rules were clarified by establishing an overlap between an aptitude model and formal reasoning.…

Discusses whether and how computer programing courses can teach problem solving. Provides results of an integrated set of studies of middle school programing students whose problem solving skills increased in a programing class. Argues that "exemplary" instruction is more efficient than "typical" instruction. Examines the influence of students'…

Compared laboratory and naturalistic content influences on formal reasoning tasks of 90 13-, 15-, and 17-year-olds, focusing on tasks requiring ability to control variables. Results indicate that 8 to 20 percent of performance variance was associated with task content. Content effects were also shown to reflect expectations about task variables.…

Illustrates advantages of research on practical factors in reasoning. Discusses role of factual knowledge and diagnosis of specific task-based errors in reasoning, influence of individual aptitudes on reasoning, and effect of educational interventions designed to change reasoning. Presents Piagetian position for each position, discusses evidence…

It has been suggested that cognitive style interacts with performance on tasks measuring formal thought. It is hypothesized that cognitive style interacts with task context rather than with the underlying formal thought processes. Experiments are reported to clarify the type of task that elicits an interaction and to determine whether such…

The procedures, major findings, and conclusions of the Adolescent Reasoning Project are summarized in this final report to the National Science Foundation. Eleven different experiments were conducted to investigate the role of naturalistic and laboratory task content on scientific reasoning. Participants involved 1500 seventh, ninth, eleventh, and…

Surveys recent literature on computer programing focusing on psychological studies of the programing task and selected instructional issues related to precollege programing. The cognitive demands and outcomes of programing, the influence of instruction on learning, and individual differences in outcomes of programing are specifically addressed.…
