Discusses the epistemology and typical applications of learning models focusing on practical methods to operationally introduce the distinctive, alloseric models into the educational environment. Alloseric learning models strive to minimize the characteristic resistance that learners typically exhibit when confronted with the need to reorganize or…

Describes how an eight year old devised a part-whole schema during a school mathematics process involving the development of a geometric model to conceptualize fractions. Provides examples that utilize this schema in dealing with the relative size of fractions, as well as addition and subtraction, multiplication, and division of fractions.…

A postsixties intellectual tendency is emerging within universities, often under the umbrella of cultural studies. Postmodern discourse is increasingly forcing in the receptivity of established disciplines to considering new knowledge objects. New movements are the context for challenges to liberal practice in contemporary higher education. (SLD)

Mothers' ways of structuring conversations about past events are related to children's abilities to structure personal narratives. When mothers provided temporally complex and informationally dense narratives about the past to their 2 1/2-year olds, the children recounted similar accounts a year later. (Author/BB)

Compared are the van Hiele levels of geometric thinking and the geometry curriculum recommended by the National Council of Teachers of Mathematics Curriculum and Evaluation Standards for School Mathematics. Activities which illustrate the various levels are provided by grade level with procedures. (CW)

A study compared university chemistry students' (n=19) performances in creativity exercises, concept mapping, and traditional examinations. Performance in all three correlated with deep study strategy, but low correlations between the three methods suggests that they test different aspects of chemistry knowledge. Use and integration of all three…

A conceptual framework is presented for organizing and relating terms pertaining to select knowledge constructs. In constructing this framework, definitions are derived for 27 basic terms essential for understanding literature on learning and literacy. Implications of this terminology for research and instructional practice are discussed. (SLD)

Reports an experimental study of 80 ninth grade biology students randomly assigned to treatment and control groups to determine whether the use of human examples in instructional strategies on Mendelian genetics increases acquisition and retention of genetics concepts. Results indicate that use of human examples in contrast to traditional examples…

Reported is a naturalistic study of the role of mathematical paradoxes in the preservice education of high school mathematics teachers. Findings indicate that the model of resolving paradoxes as applied in this study has relevance to such aspects of mathematics education as cognitive conflicts, motivation, misconceptions, and constructive…

The relationship between concept mapping and comprehension was investigated in conjunction with science instructional laboratories. Measured were student skills and aptitudes applying aptitude treatment interaction procedures to investigate interactions between a concept mapping treatment and student aptitudes. (KR)

Interviewed 10 students in a secondary school teacher education program to determine the students' understandings of environment. Four conceptualizations of environment were portrayed: social, political, bio-physical, and inclusive. Four conceptualizations of human-nature relationships were described: connected, separate,…

The main thesis of the paper is that geometry deals with mental entities (the so-called geometrical figures) which possess simultaneously conceptual and figural characters. The paper analyzes the internal tensions which may arise in figural concepts because of their double nature, developmental aspects, and didactical implications. (Author/MDH)

Reports on a study of 129 secondary students' cognitive style as related to instructional effectiveness. Finds that graphic and pictorial information improves fact retention. Recommends that teachers and teacher trainers should be aware of students' learning styles and attempt to meet their needs. (CFR)

Investigates conceptions of the geosciences held by a university geology instructor and five students before and after a teaching intervention. Argues for the use of repertory grids to elicit personal constructs. Advocates targeting the societal aims of geological education within a constructivist framework. Contains 54 references.

Explores African students' use of traditional Sotho cultural metaphoric reasoning in classifying everyday situations as "hot" or "cold" in order to document the extent to which such metaphoric reasoning is related to science misconceptions of heating. Finds that university students were able to distinguish between types of…
