Discusses the use of autobiography and personal memoirs as teaching tools in the history classroom. Presents information from Henry Watterson's autobiography that discusses the life of Jane Cazneau. Points out flaws in which incorrect information is presented as true. Includes a complete lesson plan for use with the example. (DK)

Describes an experiment to determine which of four objects, hollow cylinders, solid cylinders, hollow balls, and solid balls, will reach the bottom of an inclined plane first when released simultaneously. Provides solutions to the problem and supplementary exercises. (MDH)

This study compares inservice (n=30) and preservice (n=30) earth and space science teachers on general mental abilities, content knowledge, Gagnean levels of content knowledge, and procedural knowledge in solving earth and space science problems. Results support Norman's theory of learning that inservice teachers function at the tuning mode of…

Presents study results showing that a range of modes of interactive organization coexist in expert-novice problem-solving activity and vary with the asymmetry of the relationships. Reports that by combining high achieving status with task-related expertise, the resulting interactive dynamic is guidance/tutoring. Argues for multidimensional…

Discussed is a method of approximating the roots of a quadratic that allows the discovery of relationships between parabolas and circles and between the use of geometry and algebra. Included are the procedure and justification of the method. (KR)

Discussed is the type of evidence children find to be convincing using either empirical or deductive methods to justify propositions which they consider to be true. Included are the problem, research design, and the conclusion. (KR)

Described is a computer software package suitable for teaching and research in the area of multicomponent vapor-liquid equilibrium. This program, which has a complete database, can accomplish phase-equilibrium calculations using various models and graph the results. (KR)

Explains factors that influence novice teachers' discipline problems to help students, novice teachers, and teacher educators deal with the problems. The article describes assertiveness as a process for dealing with and preventing such problems and discusses reasons why it can be useful and effective. (SM)

Analysis of medical residents' clinical performances in five teaching hospital anesthesiology departments revealed that noncognitive performance in some areas was a powerful predictor of overall clinical performance and was related to the occurrence of critical incidents. Noncognitive predictors included conscientiousness, management, confidence,…

This paper presents a theoretical framework for investigating the role of algorithms in mathematical thinking using a combined ontological-psychological outlook. The intent is to demonstrate that the processes of learning and of problem solving incorporate an elaborate interplay between operational and structural conceptualizations of the same…

An open-ended data-analysis activity, prompted by a Royal Mail advertisement, explores the claim that the real cost of first class postage has fallen below the inflation rate. The activity provides realistic exercises in both arithmetic and statistical indices, and in logical interpretation of, and deduction from, the data. (JJK)

Presents six learning activities dealing with planetary motion, the launching of satellites, and Halley's comet, all of which utilize the three laws of Johannes Kepler. These three laws are discussed in detail, and answers to the activities are provided. (KR)

Presents illustrated examples that promote problem solving through the student's consideration of a visible predicament from a three-dimensional viewpoint rather than the typical planar perspective. Includes six student exercises involving rays, circles, quadrilaterals, and hexagons, with hints and solutions provided. (JJK)

Reports on specific problem-solving difficulties of 240 chemistry teachers from 5 Nigerian states who volunteered to take part in 3 written tests and an interview. Describes the contrasts between successful and unsuccessful problem solvers, and discusses the pedagogical and psychological implications of the findings. (16 references) (JJK)

Suggests that a reductionist and mechanistic epistemology of present Environmental Education (EE) systems impedes the ability of EE to be an agent of environmental problem solving. Using an action research approach, presents EE as a transforming agent to enable epistemological change. (22 references) (Author/MCO)
