Presents a taxonomy that organizes learner activities into the dimensions of mental, social, and physical involvement. Applies the taxonomy or model to speech class activities and reports validity evidence from several research studies. (PD)

This paper presents a reasoning taxonomy to explain reasoning objectives, strategies, and habits available to the advanced thinker. It begins by explaining the first part of the taxonomy, objectives of reasoning, including the need for skilled thinkers to reason with a purpose and to understand how the world works so that they can engage with it.…

Describes a series of exercises designed to develop student's perceptual skills and to improve the processes of comparing, describing, and developing subsets. Includes suggestions for adapting the exercises into science lessons, providing tips for developing each into complete units. Units include human-made objects, leaves, shells, rocks, and…

Presents the results of a study of cognitive components in the diagnostic thinking process in which a content analysis of interviews between patients and clinical medical students, house officers, and graduate medical students revealed 14 categories of cognitive activity in the process. Six tables and a reference list are included. (Author/JL)

Analyzed the Weigl-Goldstein-Scheerer Color-Form Test using a sample of Danish children. Distinguished three dimensions: configuration of sorting, verbalization of the sorting principle, and the flexibility of switching sorting principle. The three dimensions proved themselves to constitute the a-priori-defined gradients. Results indicated a…

The effectiveness of a procedure for identifying certain cognitive processes used during problem solving is explored. The procedure was used to: categorize types of conceptual thinking problem solvers employ; study the use of trial-and-error behavior; and investigate abilities to coordinate multiple bits of information. (Author/GK)

The comprehension of sentences with "because" or "if" was investigated in children aged 2, 9-11, and 11. (Author/MP)

Describing key instructional elements in each of Gagne's five categories of learning objectives, this article outlines numerous teaching strategies drawing illustrations from the social studies area. Also outlined are 10 steps to achieve multiple objectives and reduce problems of matching objectives, learning modes, and teaching strategies. (SB)

Reports on data obtained in Australia on practicing teachers' thinking as they interacted with a professional development interactive multimedia courseware package. Two types of thinking are discussed: (1) cognitive mediating processes related to content; and (2) evaluative thoughts about the instructional design of the courseware, from which a…

Examined the nature of perceptual classification in children and young adults. Found that most children attend selectively to one stimulus dimension when making perceptual classification judgments. Suggests that this developmental trend does not appear to be a holistic-to-analytic shift but rather a trend toward greater consistency in following a…

Examines two methods of differentially classifying language-delayed children as either specifically language impaired (SLI) or developmental-lag language impaired. Results indicated significant differences in classification between the two methods of defining SLI, as well as substantial changes in classification over time using either method. (47…

This study examined the matching and sequencing of quantities, numerals, and arbitrary forms by two individuals with mental retardation. Results showed that sequence training did not readily lead to new matching performances, unlike prior research with college students. Instead, training in matching to sample yielded emergent sequence production…

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classification of mentally retarded children. Results support a distinction between separable and integral stimulus structures, but do not support an integral-to-separable shift in perceptual development. Results suggest implications for…

Second, fourth, and sixth graders were given passage of text whose material could be represented as four-level class inclusion hierarchy. Students were asked to construct external representation of passage and answer questions that required them to reason about contents of passage. Quality of representation and performance on question tasks were…

Two experiments examined preschoolers' and adults' relative reliance on visual and verbal information in identification of animals and machines. Findings include both children and adults can use either visual or verbal cues in categorization, and a stricter definition is used in identifying animals. Results suggest that a perceptual to conceptual…
