Histories of mathematical practice account for mathematical knowledge and action by interpreting presently-available evidence as traces of the events, contexts, and relations that make up the past. Interpretations depend on the assumptions one makes about how mathematical knowledge works, insofar as it is knowledge and insofar as it is…

This guidance report focuses on the teaching of mathematics to pupils in Key Stages 2 and 3. It is not intended to provide a comprehensive guide to mathematics teaching. We have made recommendations where there are research findings that schools can use to make a significant difference to pupils' learning, and have focused on the questions that…

The National Science Foundation funded a synthesis study on the status, contributions, and future direction of discipline-based education research (DBER) in physics, biological sciences, geosciences, and chemistry. DBER combines knowledge of teaching and learning with deep knowledge of discipline-specific science content. It describes the…

Reports on an experiment where novice and expert programmers made decisions about Fortran code segments. The results show that, although expert programmers are better able to extract and use functional information, they don't differ significantly from novices in their ability to use syntactic concepts. (Author/EM)

When two-, three-, four-, and five-year-olds were tested for knowledge of sex role stereotypes and preferences for sex-typed activities, boys' stereotype acquisition lagged behind preference development. Girls' data were ambiguous. Boys displayed equally strong tendencies to endorse same-sex activities; girls displayed a stronger tendency to…

Examines reasons for sex-related differences among adults on horizontality and verticality concepts. Studies the effects on task performance of inadequate knowlege of relevant physical phenomena and pictorial examples. (Author/AS)

Concepts used by two classes of grade eight students, one advanced and the other average, to explain the changes that occur when water is heated to boiling are presented. Little difference was found between groups in terms of the personal misconceptions used to explain boiling. The changes that take place in conceptual knowledge immediately after…

Propositions expressed by students during interviews prior to and after audiovisual instruction served as the basis for Concept Propositional Analysis (CPA) to assess cognitive structure. CPAs for two students are reported and aspects of Ausubelian principles are discussed. The method showed that new learning can be linked to previous…

A small set of relationships has been identified which appears to be sufficient for describing all molecular and cellular reactions and structures discussed in an introductory biology course. A precise definition has been developed for each relationship. These 20 relationships are of four types: (1) analytical; (2) spatial; (3) temporal; and (4)…

Demonstrates the usefulness of the inclusion paradigm as a methodological tool in providing information about the conceptual breadth of selected social and nonsocial superordinate categories in children who exhibit some degree of inclusion logic. (HOD)

A major goal of science education is to turn novices (students) into experts (scientists or science literates) with a minimum amount of pain, effort, and time. However, transfer of biology knowledge from instructor to student usually results in a loss of the rich interconnections that an expert has. The papers in this set describe efforts to…

Studied a limited number of students exposed to teaching materials and strategies (developed from a cognitive perspective on learning), such that their impact would be monitored to determine how the learners constructed new knowledge frameworks as teaching proceeded. Includes background information, comparisons of teacher's intentions and…

The development of children's understanding of the learning process and factors that affect learning was explored with a sample of 18 children from 6 to 13 years of age. Subjects were interviewed, and three levels of their reasoning were identified. The 6- to 7-year-old subjects viewed learning as "doing" and reasoned that…

This paper analyzes the hardware and software features that would be desirable in a computer-based semantic network system for representing biology knowledge. It then describes in detail a prototype network of molecular biology knowledge that has been developed using Filevision software and a Macintosh computer. The prototype contains about 100…

Summarizes findings of a collection of research studies at the University of Aberdeen (Scotland) aiding fundamental understanding of knowledge representation and its applications. Issues arising when a knowledge representation system is incorporated into an authoring language are discussed, including the problems of exteriorization, metacognition,…
