This paper criticizes the Yeany, Yap, and Padilla paper (1986). Questions the internal consistency about hierarchical relationships of integrated processes and cognitive reasoning concerning procedures used for the generation of subhierarchies, instrumentation used to assess the process skills, and rigor of lexicon.

Proposes a theoretical model of cognitive development and applies this model to the secondary analysis of two large-scale studies which focus on the acquisition of formal operational schemata by adolescents in the United States and Israel. Results support the "unity" hypothesis of cognitive development that the various schemata of formal…

Investigated was the relation between student ability to translate sentences into equations, equations into sentences, and student performance in formal operational reasoning, proportional reasoning, and introductory-level chemistry. Results indicate that students who lack formal operational skills may experience problems in the translation of…

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)

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…

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…

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 is the ability of high school pupils and university students to answer questions based on relationships within food webs using sound ecological principles. Research methods used and the results of this study are discussed. (CW)

Misconceptions, shown to be prevalent in students even at the college level, may affect the cognitive process of making predictions in biology. The purpose of this study was to: (1) identify students' misconceptions about important biological concepts; (2) identify students' cognitive behaviors associated with making predictions about these…

The present study was designed to test how well the measures of the cognitive constructs of M-space, cognitive style, and short-term storage space (STSS) could predict the amount of practice needed to induce successful problem solving behaviors, the ability to transfer behaviors to different contexts, and the readiness to abandon unsuccessful…

Investigates whether distinctions in cognitive structures between formal and concrete operational students effect their ability to produce an accurate cognitive structure, retain geometric content, and retain cognitive structures. Concludes that clear structures can be derived for the students. (Author/YP)

Considers the period of adolescence and describes how cognitive-developmental concerns might apply to the understanding of adolescent problems in interpersonal and affective adaptation. Also investigates ways in which intervention practices with adolescents might be placed within a cognitive-developmental context. (PCB)

Investigates the relationship between the strategies used by preservice elementary teachers in geometric problem solving and two primary mental abilities--spatial visualization and formal reasoning. Reports that the two abilities were related to problem-solving performance, and the strategies used were related to achievement in the geometry…

Determined was the effect that cooperative groups heterogeneously based on proportional reasoning ability have on problem solving in regular and honors high school chemistry. Characteristics of successful and unsuccessful problem solvers individually and in groups are discussed. (KR)

Reviews the neural modeling principles of learning, perception, cognition, and motor control, discusses their applications to sensory-motor problem solving, and explores possible relationships between that pattern of problem solving and aspects of higher order formal operational problem solving. Cites implications for science education. (ML)
