Eighteen children (mean age 10.2 years) with mild mental retardation were pretested on a variety of measures and then instructed on Piagetian concepts twice per week for 4 months via a learning set technique. When posttested at semester's end, the children had, with few exceptions, mastered the concepts and made significant gains on the Peabody…

The constructivist hypothesis that the acquisition of domain-specific conceptual knowledge (declarative) requires the use of general procedural knowledge was tested. Students (n=314) were classified as reflective, transitional, or intuitive thinkers and presented with four concept-acquisition tasks. Skill in hypothetico-deductive reasoning…

The development of students' (n=80) conceptions of matter was investigated. Students' ideas about matter were examined by asking students to verbally explain what matter means and to classify items into matter and nonmatter. A major difficulty is indicated by students regarding the concept of matter. (KR)

New methods for representing the structural properties of domain-specific knowledge were studied. Network representations of data from 40 college students' ratings of the relatedness of domain concepts were derived using the Pathfinder scaling algorithm, and similarity between students' and instructor's networks was then assessed using a…

The role of analogical mapping in the formation of conceptual misrepresentations was studied by analyzing target-domain inferences generated by 193 third graders learning from an analogy. Explicit knowledge of the instructional goal decreased the number of conflicting inferences. Implications for learning are discussed. (SLD)

The concept of metacognition is discussed, with a review of attempts at definition. A. Brown's (1987) four historical roots of metacognition--verbal reports as data, executive control, self-regulation, and other-regulation--are summarized. Influence from the developmental theory of L. S. Vygotsky (1978) may result in a clearer conceptualization of…

Discusses Hilda Taba's ideas and influence on the social studies curriculum and her work on a project to develop instructional guides for social studies teachers. Explores the importance of developing multiple objectives and organizing subject matter into key concepts, organizing ideas, and specific facts. Recommends emphasis on thinking, people,…

Discusses two authors' views on critical thinking. McPeck denies the possibility of critical thinking, stating it is burdened by informal logic. Paul believes critical thinking includes logical, epistemological, psychological, and social dimensions springing from moral and political concerns. The paper examines the debate over general versus…

Assessed differences in teaching of the theme of "the shop" in four Swedish preschools and outcomes in terms of children's understanding. Interviews of children were used to assess their levels of comprehension of the workings of a shop. Results indicated that children from experimental groups developed a significantly better…

Proposes a systematic way of defining the concept of professional development and revealing its structure through use of a mapping sentence based on analysis of the concepts of development and profession. The mapping sentence may guide teacher developers in planning programs to suit varying concepts of professional development. (SM)

This article introduces a series of papers that explain and illustrate how a higher order thinking curriculum can be designed for a full spectrum of students, including students with learning disabilities. The article discusses an approach in which concepts, rules, and strategies are taught by organizing content around the process of noting…

The complex interactions between picture, text, and learner are examined, based on a 3-D model which describes the context of the learning task. The different strategies that children of various ability levels use in reading from illustrated texts are described. (KR)

The manner in which seven male expert credit administrators and seven male trained nonexpert credit administrators differed in their ability to generate and verify inferences was studied. Results suggest that the ability to reason within a complex domain requires more than simply acquiring knowledge. (SLD)

Results indicate that curvilinear trend in children's understanding of word "big" is not obtained in all stimulus contexts. This suggests that meaning and use of "big" is complex, and may not refer simply to larger objects in a set. Proposes that meaning of "big" constitutes a dynamic system driven by many perceptual,…

Describes three episodes illustrating teacher's and preservice teacher's difficulties in teaching evolution. Presents a series of activities for teaching evolution using the conceptual change approach to teaching science. (PR)
