The author examines current techniques used to teach elementary school children how to analyze and compare. Emphasis is placed upon developing these modes of mental activity while teaching biological concepts. (DE)

Psychological equilibration (internal mental process by which individuals develop intellectually) is discussed in terms of its origin in the biological theory of evolution and in the thinking of Jean Piaget. The importance of equilibration theory for biology instruction is then considered. (Author/JN)

Argues that much of current science curricula and instructional strategies do not accommodate the thinking and reasoning capabilities of students. Level of capacity for abstract logical reasoning, whether the capacity can be cultivated/enhanced, consequences of mismatched intellectual levels and instructional modes, and what thinking/reasoning…

Determined if student questioning skills could be taught within framework of an ongoing chemistry course and if acquisition of these skills depends on high school students' (N=108) level of intellectual development. Results indicate that questioning skills can be acquired by students, regardless of their level of Piagetian intellectual…

A model for the development of elementary and secondary instructional materials covering the broad range of intellectual skills is presented. The document is a result of a search to identify and evaluate existing instructional materials, classification schemes, models, hierarchies, and taxonomies of cognition. It is presented in four sections.…

Discusses a study that examined which reasoning patterns are necessary for success in high school chemistry. Based on student (N=170) scores from the "Classroom Test of Formal Reasoning," it was revealed that students who use formal reasoning patterns are capable of greater achievement in chemistry. (ML)

The level of thinking that is characteristic of the typical college freshman and the skills needed by college science courses are addressed, and the Development of Reasoning in Science project (Project DORIS) at California State University, Fullerton, is described. While the typical college freshman functions at the concrete level of thinking,…

Examined influence of teaching methods on content achievement of concrete and formal concepts by students differing in level of operational thought and influence of concrete/formal teaching on the intellectural development of students (N=86 grade 9-10 biology students). Methodology, results, conclusions, and implications are discussed. (Author/JN)

Discusses whether formal thought constitutes a structured whole and role of propositional logic in advanced reasoning. Presents aspects of advanced reasoning model, considering hypothesis generation/testing as central processes in intellectual development. Argues that advanced reasoning schemata are linked by these processes and should be…

Outlines the constructivist model of knowledge and describes how this model relates to Piaget's theory of intellectual development. Contrasts the constructivist model with the traditional views of knowledge. Discusses how this model can help explain some of the things that happen in chemistry classrooms. (TW)
