It is urgent that we re-examine models of knowledge and knowledge-making within the university, at this time of open learning and deregulated multi-million dollar and euro open science hubs and portals. For otherwise, we are bound into "crude" instrumentalism, "delivering" "knowledge packets" rather than seeing our…

Two thinking strategies, concept formation and dialectical reasoning, are discussed and illustrated. The need for schools of education to teach thinking skills is stated, and concepts which should be addressed are suggested. (Author/MT)

The results of a study of the meiosis models utilized by individuals at varying levels of expertise while reasoning about the process of meiosis are presented. Based on these results, the issues of sources of misconceptions/difficulties and the construction of a sound understanding of meiosis are discussed. Five individuals from each of three…

Data analysis revealed that a post-organizer had a significant facilitating effect on immediate free-recall in a controlled lecture in college statistics, but no effect on immediate content recognition or delayed free-recall. (MP)

It has been shown previously that many students solve chemistry problems using only algorithmic strategies and do not understand the chemical concepts on which the problems are based. It is plausible to suggest that if the information is presented in differing formats the cognitive demand of a problem changes. The main objective of this study…

Approximately 500 nonscience major university chemistry students were surveyed to record their interpretations of specific chemical symbolism before presenting modern concepts of atomic and molecular structure, in an attempt to understand the thought processes entering students use as they interpret symbolism. Results are reported and discussed.…

Abstracts and abstractors' critiques are presented for six studies dealing with concept formation and misconceptions and for five studies dealing with cognitive development. The first six studies investigated: children's naive conceptions of the human body; students' understanding (or misunderstanding) of states of matter and density changes; the…

This paper presents a challenge to a widely cited report by Elkind which states that a large proportion of college students, particularly females, are unable to conserve volume. (BD)

This study observed and documented the changes of college students' notion of mathematics functions in a virtual environment that integrated a synchronous and asynchronous Computer Mediated Communication system. Four Arizona State University undergraduates were teamed into pairs and solved function problems in the virtual classroom over a one…

Describes the problem-solving behaviors of six novice subjects attempting to solve an electrostatics problem in calculus-based college physics. The level of qualitative thinking exhibited by these novices was determined. Sound procedural knowledge and problem representation were suggested as an integral part of skilled problem solving in physics.…

Two inquiry-based teaching activities that are structured to cause cognitive disequilibrium and enable the student to alleviate the disequilibrium with the resultant equilibration at a higher cognitive level are presented. The first activity uses a Cartesian diver and the second a short film in which students are asked to determine the main idea…

An overview of the research on the cognitive effects of higher education is presented. It is suggested that studies exist on three levels: (1) measurement of the increment of specific factual knowledge; (2) understanding the basic concepts in a certain area, studied by qualitative analysis; and (3) the development of awareness of the nature of…

Discussed are categorization schema, with elaborations about attendant epistemological obstacles, concerning the twin notions of understanding and comprehension, per se, as well as the processes affecting their attainment. Included is an example of such a schema involving the concept of the limit of a numerical sequence. (JJK)

Endorses concept mapping as the way to achieve the most meaningful learning. In concept mapping, concepts are organized according to their hierarchical relationships. Concept-mapping skills can help to organize and integrate information, assess existing knowledge, gain more insight into all knowledge, and relate basic science concepts to the…

This study explores the nature of professional expertise in economics. Two experiments were conducted to examine the existence of problem categories in economics as a basis for problem representation. Findings are that experts use categories that reflect major economics principles, and novices sort by literal cues contained in the problems. In the…
