Recent research in cognitive science and science education suggests that science-naive individuals have an understanding of the natural world based on their interpretation of everyday experience. This can make the process of conceptual change difficult. This paper presents ideas related to the acquisition of knowledge in astronomy. A theoretical…

Developing a constructivist view of scientific inquiry and knowledge is considered to be important to the training of future scientists, as well as to the understanding of scientific information by all citizens. The research reported targets the junior high school grades. Curricular materials that introduce seventh graders to the constructivist…

Describes a multiple-choice instrument that reliably and validly diagnoses secondary students' understanding of photosynthesis and respiration in plants. Highlights the consistency of students' misconceptions across secondary levels and indicates a high percentage of students have misconceptions regarding plant physiology. (CW)

This book brings a philosophical perspective to the topic of children's thinking. It attempts to answer the questions of what it is to think and understand, and how children do so.

Explores what kinds of calculus-related insights seem to typify calculus-related reasoning. Introduces "qualitative calculus" in which learning is focused on synthesis. Discusses the resemblance and difference between traditional calculus and qualitative calculus, advantages of learning qualitative calculus, and how understanding qualitative…

Discussed are the principles of Gestalt psychology and the history and future of the movement. A comparison of Gestalt, Behaviorist, and Structuralist ideas is included. The study of perception, learning, memory, and thinking from the Gestaltist point of view is described. (KR)

Described is a study of 147 students that indicated a high proportion of students did not understand the concept of limiting factors. Textbook presentations that create problems are discussed. Strategies which may be more effective in teaching the concept are suggested. (CW)

Examined 8- and 10-year olds' understanding of the unique features of and potential relations among mental activities. Found a developing tendency to organize mental activities on the degree to which memory was a component of the activity. Results suggest that a constructivist theory of mind develops in later childhood. (AA)

Discussed is the idea that students come into their lessons with already preformed notions for many basic astronomical events. Examples of students' responses during an astronomy lesson are included. Suggestions for uncovering students' alternative frameworks are presented. (KR)

Discussion of computer programing at the secondary level focuses on automation and schema acquisition as two processes important in learning cognitive skills such as programing. Their effects on learning outcomes and transfer of training are examined, the importance of worked examples is highlighted, and instructional design principles are…

Presents a knowledge representation model that was designed for instructional decision making. Topics discussed include classification models for instructional design; artificial intelligence; semantic networks; natural language; and data models, including network and hierarchical models. An example is given of knowledge analysis for a secondary…

Discussed is a constructivist model of science learning and its possible use in the treatment of science misconceptions. Science learning as conceptual and methodological change is described. (KR)

For the past ten years the management literature has increasingly discussed the concept of learning organizations. Yet, more that a decade later, few organizations have figured out how to create the structures and processes necessary to assure continuous learning. This article purports that this problem can be attributed to the mental models of…

People's mental models are viewed as being significant in achieving organizational outcomes, on the assumption that mental models influence people's acts. A fundamental issue in the area of organizational learning, then, is the relation between mental models, learning and performance. We contend that a fruitful line of work is to study persons as…
