Describes a study, involving 120 first grade children, which supports the hypothesis that the rate of attainment of conservation skills is significantly enhanced by experiences made possible by the first grade program of SCIS. Describes the six conservation tasks used for pre-tests and post-tests: number, liquid amount, solid amount, length,…

Studied discriminative and investigatory response behavior and effects of response training on children 4-5 to 6-5 years of age. (DR)

"A new sort of concept attainment or decoding-encoding experimental paradigm based on the model is developed and an experiment on 5-, 7-, and 9-year-olds is reported. (Author)

Discusses children's acquisition of non-nominal, abstract words and argues that the use of these words parallels the child's cognitive development in trial-and-error problem solving and in development of insight. (EKN)

The author discusses how to select microcomputer software for an accounting program and what types of instructional modes to use. The following modes are examined: problem solving, decision making, automated accounting functions, learning new accounting concepts, reinforcing concepts already learned, developing independent learning skills, and…

Investigates the interaction between semantic knowledge and process skills in eighth-grade students' (N=27) performance in solving two types of problems (analogies and set-membership) of inducing structure drawn from physical geology concepts. (DS)

Two experiments were carried out in order to test the effects of task sequence on the speed of rule learning and problem solving. Experiment I involved numerical rule-learning tasks and Experiment II tested the effect of task difficulty and task precedence using problem-solving tasks. (Editor/RK)

Shows how attention to transcending functions provides a new integrative approach to mathematics that can improve the critical thinking and problem-solving skills required for addressing large-scale problems. Contains 38 references. (DDR)

Discusses the value of introducing students to problems that lend themselves to long-term, in-depth analysis at different levels of intellectual accomplishment. Focuses on one such problem in detail. (DDR)

Describes a study which concluded that, to restructure the mathematics curriculum, modification of existing teaching practices is required. Recommends that practices be modified to enable students to construct effective knowledge bases and become active learners. Contains 38 references. (DDR)

Discusses the nature of tasks used to elicit the development of such systems by middle school students. Analyzes mathematical reasoning development of students across tasks and the diversity of thinking patterns identified on problem tasks. Discusses student reasoning about the relationships between and among quantities and their application in…

Presents a case study in which two 8th grade students developed knowledge for modeling a physical device called a winch. Demonstrates that students have and can use criteria for evaluating algebraic representations. Explains how students can develop modeling knowledge by coordinating criteria with knowledge for generating and using algebraic…

Investigates the relationship between traditional physics textbook problem solving and conceptual understanding. Reports that students had many of the well-known conceptual difficulties with basic mechanics and that there was little correlation between the number of problems solved and conceptual understanding. (Contains 21 references.)…

Describes similarities and differences between modeling cycles and stages of development. Includes examples of relevant constructs underlying children's developing ways of thinking about fractions, ratios, rates, proportions, or other mathematical ideas. Concludes that modeling cycles appear to be local or situated versions of the general stages…
