Discussed is the teaching of physics with an emphasis on the learning of concepts before problem solving. Examples of this approach are provided. (CW)

The development of suicidal thoughts in children was studied, using life history data from 364 undergraduates. Results suggest that: many children and adolescents contemplate suicide, and those at increased risk of suicidal thought are also at increased risk of suicide. Examining suicidal ideation in non-clinical samples is discussed. (SLD)

Investigates the relationship between knowledge of geometrical optics and the understanding of the phenomenon of colored shadows through adult interviews. Reports that the knowledge of geometrical optics facilitates the pinpointing of the color problem while experience with the mixing of paints may act as a barrier. (Author/YP)

Considers six key concepts in human genetics in a question-and-answer format designed to help guide students to an understanding of the concept. Lists eight workshops in human genetics for high school biology teachers and four curriculum material packages on human genetics. (CW)

Explains the differences between successful and unsuccessful problem solvers' exploration of a problem, translation of information into different forms, approach to devising and executing a plan, and rechecking work. (RT)

This study of sixth grade industrial arts students examined the relationships among declarative, conceptual, and procedural knowledge in the acquisition of ruler measurement skills. Results for 90 sixth graders indicate that the line identification method was superior overall to the fractional method, for both acquisition and retention of skills.…

Examines the development of students' understandings about fractions during six weeks of instruction. Reports that all students possessed informal knowledge disconnected from their knowledge of fraction symbols and procedures and that knowledge of rote procedures often interfered with students' attempts to build on their informal knowledge.…

Discusses how to help children acquire mathematical concepts and teach for precise mathematical concepts. Describes four activities to reinforce the concepts introduced. (YP)

Reports on a study based on the theory of constructive alternativism. Analyzed students' reactions to a photograph of an Indian village to learn what impact the students'"personal geographies" had on the reconstruction of the image. Suggests ways teachers can use these images to enhance students' understanding of world issues. (LS)

Identifies an induced incorrect generalization as a generative cause for the formation of misconception. Analyzes students' protocol of an exploratory learning experiment about the laws of reflection of light. Suggests recommendations for textbook, teaching, and practical work. (Author/YP)

Over half of the 101 preservice elementary teachers studied accepted inductive arguments as valid mathematical proofs, while over 60 percent accepted correct deductive arguments. Over one-third simultaneously accepted inductive and deductive arguments. More examples of the limitations of empirical evidence and of the power of mathematical proof…

College instructors can design discussion classes so that students use the concepts and processes of the discipline to evaluate facts and move toward reliable conclusions. Described are: discussion as a cycle of inquiry; creating tension around ideas; seeking causal relationships; scanning the factual base, etc. (MLW)

Discusses problems associated with teaching non-recursive binary searching in computer language classes, and describes a teacher-directed dialog based on dictionary use that helps students use their previous searching experiences to conceptualize the binary search process. Algorithmic development is discussed and appropriate classroom discussion…

Recent research in science education examines learning from four foci: (1) concept learning; (2) developmental; (3) differential; and (4) problem-solving. These perspectives provide a framework for identifying mechanisms of change in knowledge/thinking processes. In-depth coverage of several science topics may benefit students more than fleeting…

Investigated were the effects of programing instruction with BASIC on mathematical thinking skills and concept development in grade six. Posttests assessed programing ability, generalization, and understanding of variables. Observations and interviews were also used. The groups having programing instruction scored significantly higher than the…
