Students bring prior knowledge to their learning experiences. This prior knowledge is known to affect how students encode and later retrieve new information learned. Teachers and content developers can use information about students' prior knowledge to create more effective lessons and materials. In many content areas, particularly the sciences,…

Considered are two commonly used techniques, the interview and word association techniques. Highlighted is a third technique called the repertory grid. This third technique can be used to interpret students' knowledge based on an explicit, psychological theory of human behavior. (Author/CW)

The science learning cycle developed by Robert Karplus and others in the 1960's has been a useful model for many science teachers and researchers. This model stresses the use of structured inquiry to organize knowledge acquisition and problem solving. Recent research in the cognitive science tradition, however, has shown that learning and problem…

Explores how some of the work in the history and philosophy of science might develop a more adequate understanding of students' untutored ideas. Describes how students' views can be interpreted. Explains and discusses the merits of commonsense-scientific theory analogy. (YP)

Children's ideas about radiation and radioactivity are reviewed and several common areas of misunderstanding are identified. An approach to teaching the topic at the secondary school level which seeks to specifically address known difficulties is outlined. (CW)

Presented are the results of a study of high school and college students concerning their thinking about functions of the human body. It was shown that students' thinking could be positively changed over the short term from teleologic to mechanistic. Sample survey questions are included. (CW)

Primary school teachers' responses to interview questions about science concepts are described and compared in general terms with views of scientific concepts held by children. Some possible implications of the findings for the development of primary science are outlined. Sample interview questions are included. (Author/CW)

Describes an application of methodology based on the Information Integration Theory to study intuitive mastery by 13-14 year-olds of Archimedes' Effect in physics. (Author/YP)

Discussed are problems revealed in student responses to a practical task which formed part of an advanced level examination. The frequencies with which some misconceptions about cell reproduction and genetics occurred are presented. The nature of these misconceptions is analyzed and their implications discussed. (CW)

Investigated are three misconceptions of probability and the differential effect of two activity-based instructional units. Response categories (law of averages, law of small numbers, and availability) are identified. Treatment differences (evaluation or no evaluation) appear to influence subjects' interpretations of the information. (YP)

Examined are tenth-grade Western Australian students' conceptual knowledge of gravity and the motion of the planets. Students were interviewed with seven cards, and a four-item diagnostic test based on the interview data on the first four cards was developed. A total of 113 students' responses to the test are summarized. (YP)

Discussed is a common error made by students in judging the distribution of the magnetic field of a circular loop along its diameter. Qualitative and quantitative explanations of the magnetic field distribution are presented. (CW)

The results of survey of secondary school biology students used to access misconceptions about cells are presented. A distinction between conceptions, misconceptions, and nonconceptions is drawn in terms of secondary school biology concepts. The resilience of misconceptions is discussed. (CW)

Described are the results of a conceptual physics survey given to a small group of high school physics students with the goal of identifying common misconceptions held by students. Three common misconceptions were identified and are discussed in detail. (CW)

This paper analyzes the misconceptions high school students have about force and suggests that the misunderstanding of Newton's third law is the key to these misconceptions. Clinical interview and diagnostic test data (N=104) indicates that many students have a naive view of force as an acquired or innate property of single objects rather than…
