The focus is on the ability to create and relinquish hypotheses in problem solving. Given are activities that illustrate how to stress the importance of producing and evaluating new ideas. A hidden rule game, microcomputer software, and an attribute game are described. (MNS)

Reports the results of a high-speed search task administered to overactive and distractible (hyperactives), normoactive and distractible, and normoactive and attentive (controls) children. Instructions emphasized speed, accuracy, or both speed and accuracy. Indicates that controls and distractibles conformed to the fast guess model, which relates…

Fourth-grade students' understanding of the order and equivalence of fractions was investigated in an 18-week teaching experiment. Three related characteristics of thinking are hypothesized to be related to success of such tasks, involving flexibility and reasoning that becomes increasingly independent of specific concrete embodiments. (MNS)

In one school, algorithmic development has been infused in the mathematics curriculum. An example of what occurs in mathematics classes since the teachers began using the computer is given, with two students' conjectures included as well as the algebraic justification. (MNS)

Proposals for teaching concepts have been dominated by traditional paradigms. A review of research on concept structure and formation reveals evidence for alternative paradigms, e.g., exemplar, probabilistic, and schematic models. The research also indicates problems regarding the traditional models. Implications for relating alternative models to…

The research and development of mental (standardized) testing and its relationship to educational practice is traced historically from its pre-World War I roots to its controversial national prominence in the 1970s. How standardized tests have been used in research and in schools is analyzed. (BS)

Describes a study done to determine whether the degree of children's familiarity with component words was related to (1) their ability to produce productive patterns as opposed to associative and grouping patterns, and (2) their ability to use broader scope rather than lexically based patterns. (SED)

Reviews the background leading to the development and evaluation of problems to examine student ability to do qualitative reasoning, applying concepts rather than algorithms. Describes creation of quantitative and qualitative problem papers, summarizes results, and proposes distinctions based on cognitive difficulty. (JM)

The study of trigonometric functions in terms of the unit circle offer an example of how students can learn algebraic relations and operations while using visually oriented thinking. Illustrations are included. (MNS)

Research on when and how geometric concepts are learned is briefly discussed. Several teaching suggestions are included. (MNS)

Using 80 female undergraduate students, this study investigated the hypothesis that field-independent individuals are more efficient in verbal restructuring tasks than field-dependent individuals. Results of an analysis did not support the hypothesis. (Author/LMO)

This study investigates whether groups of children on a microcomputer task show superior performance to individuals and whether the differences are due to social-cooperative or individual-cognitive facilitation. Considers the relationship between expressed knowledge and problem-solving performance across three conditions. (Author/CT)

Describes a metacognitive study method, LETME, designed to help students manage the entire study process by facilitating the understanding, selection, organization, retention, and analysis of information from expository text. (DF)

Surveys artificial intelligence and the development of computer-based tutors and speculates on the future of artificial intelligence in education. Includes discussion of the definitions of knowledge, expert systems (computer systems that solve tough technical problems), intelligent tutoring systems (ITS), and specific ITSs such as GUIDON, MYCIN,…

The article stresses the importance of teaching deaf children to think and learn through the development of meaning-making and meaning-sharing capacities. Classroom practices should thus be content focused and actively engage students in American Sign Language to develop general literacy. (CL)
