This analysis of work interactions emphasizes concepts and principles adults bring to work interactions. It also explores the processes involved in teaching and learning situations, and the questions these processes raise for certain current social accounts of children's cognitive development. (BB)

The reasoning abilities to be expected of the concrete operational and formal operational student, the percentage of secondary science students that are capable of each type of reasoning pattern, and effective strategies to teach science to concrete reasoners are described. Implications for curriculum development are discussed. (KR)

Discussed are the philosophy and procedures behind the introduction of algebra to students in grade 7 in Australia. Included are the importance of concrete experiences, language development, and the consequences involved in this procedure. (CW)

The contrast between the teaching of reading and mathematics is drawn. A new set of learning conditions for mathematics is presented based on a model of reading instruction. Immersion, demonstration, engagement, expectations, responsibility, use approximation, response, refinement, and outcomes are discussed. (CW)

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

Sketches a theory for designing teaching based on mathematical activity, situations, tasks, and interventions, exposing and resolving cognitive conflicts, changes of structure and context, feedback, reflection and review. Reviews the main psychological principles underlying this theory, then considers some examples of teaching designs in light of…

Discusses (1) the need for teachers to understand student conceptions; (2) alternative conceptions that students formulate; (3) changing conceptions; (4) representing conceptual knowledge for studying conceptual change; (5) strategies for inducing change; and (6) a taxonomy of conceptual change. (Contains 61 references.) (MDH)

Conceptual change teaching is an instructional method that helps students modify, extend, or exchange their alternative conceptions for the appropriate scientific conceptions. Provides activities and a diagnostic test to apply the method to the concepts of heat and temperature. (MDH)

Describes the affective factors involved in the academic progress and achievement of newly-arrived bilingual twins in a secondary school in London. Finds that different personality traits and self-perceptions resulted in the development of their divergent personal learning styles, and that task interest, appropriate learning strategies, and…

Information processing models do not account for much of human competence in everyday scientific and lay contexts. Situated cognition models account better for competence in widely differing situations. In situated cognition models, the purpose of science education must be reconceived as preparing citizens to participate in public enactments of…

Compares two experimental programs for teaching mental addition and subtraction in the Dutch second grade (N=275). Discusses realistic program design (RPD) and gradual program design (GPD). Concludes that RPD pupils show a more varied use of solution procedures than GPD pupils. Contains 46 references. (Author/ASK)

This paper describes a framework for researching the Cognition Hypothesis which claims that pedagogic tasks be sequenced for learners on the basis of increases in their cognitive complexity. It distinguishes dimensions of complexity which increase the conceptual and linguistic demands tasks make on communication, so creating the conditions for L2…

This study investigates features of interaction between children that are linked to the development of understanding of mind, and asks whether these associations are evident across different relationships. Comparisons are made of the naturally occurring conversations in a sample of 43 4-year-old children, each observed with a sibling and with a…

This report is part of a long-term research on the construction of mathematical meanings through the interaction with various technologies. The research involved a set of teaching experiments based on body motion with sensors and calculators at different school levels, from kindergarten to secondary school. Here I refer to the one developed in a…

This study investigates young children's humourous activity as a form of play and considers the implications on their cognitive development and learning. The study was conducted in an infant room of a university based group child care center and multiple qualitative data collection methods were used. The findings of this study suggest that during…
