Discusses the results of a study that explored first year university students' ideas about measurement in the physics laboratory. Uses the 'point' and 'set' paradigms as a model to analyze responses to written probes. (Contains 21 references.) (DDR)

Examines third year university physics students' use of models when explaining familiar phenomena involving interaction between metals and electromagnetic radiation. Concludes that few students use a single model consistently. (Contains 27 references.) (DDR)

Explores high school students' collaborative efforts in solving qualitative physics problems and investigates how and whether confronting students with varying views improves problem solving skills. (Contains 22 references.) (DDR)

Describes trends in students' explanations of biological change in organisms. Student responses to questions on how graphically depicted phenomena occur were analyzed and most students were unable to offer causal explanations. (Contains 27 references.) (DDR)

Users of educational hypertext are faced with the challenge of creating meaning both within and between texts. Cohesion is an important factor contributing to whether a reader is able to capture meaning and comprehend text. When readers are required to fill in conceptual gaps in text, comprehension can fail if they do not have sufficient…

Explores whether construction of integrated knowledge structures by students can be stimulated by concept mapping and better visualization of concepts and their interrelationships. Significant effects of concept mapping as an instructional method could not be detected. (Contains 18 references.) (DDR)

Considers the role of library and information science professionals as knowledge engineers. Highlights include knowledge acquisition, including personal experience, interviews, protocol analysis, observation, multidimensional sorting, printed sources, and machine learning; knowledge representation, including production rules and semantic nets;…

Examines some of the misconceptions about the nature of critical thinking. Focuses on the characterization of critical thinking in terms of processes or skills and the separation of critical thinking and knowledge. Offers a different conception of critical thinking. (Contains 46 references.) (DDR)

Focuses on student and in-service primary teachers' learning about balanced and unbalanced forces in a range of contexts and identifies significant features of the learning process from the learners' perspectives. (Contains 33 references.) (DDR)
