Recent research on hypothesis testing strategies (the strategy a person uses to determine the correctness of a specific hypothesis) has produced contradictory results. The three strategies available have been labeled confirmatory, neutral, and disconfirmatory. Some research has found that a confirmatory testing style predominates, while other…

This study examined the effect of three aspects of the testing context--physical privacy, anonymity, and offers of help from a tester--on children's expectations. Performance of 96 11-year-old boys and girls on a pictorial recall memory task in a simulated test was evaluated. The subjects were divided into eight different groups varying on the…

Describes the construction of a knowledge representation from the identification of the problem (nephrotic syndrome) to a running computer simulation of causal reasoning to provide a vertical slice of the construction of a cognitive model. Interactions between textbook knowledge, observations of human experts, and computational requirements are…

This report summarizes an investigation of the attitudes of elementary students, teachers, and parents toward the use of educational computer games and simulations in a teaching/learning situation. Following a statement of the project purpose and a literature review, the courseware selection process is described. (This process resulted in use of…

Reviews two case studies which evaluate the use of gaming/simulation as a participatory method for including users in the design of community projects. Questionnaires and interviews are used to compare visual gaming methods with verbal discussion methods in designing an activity center for handicapped residents and a community garden project. (LRW)

Some diverse fields in which the effects of mental representations have been noticed are first discussed, largely through illustrations of differing problem-solving experiences. Then the LAKOS Project (Logical Analysis of Cognitive Organizational Structures) at the University of Osnabruck is described. A central concern is the specification of a…

A new framework for designing qualitative studies is described to optimize the emergence, representation and presentation of insights. The framework, called Reflection Methodology, is presented as a "Conversational Paradigm" that includes four components--interviewer (researcher as participant); child, task situation, and observing…

Against the background of research indicating that women are underrepresented in educational administration, this study examines the question of gender bias in the selection of superintendents. Choosing for their sample population 15 school districts from central Oklahoma, the researchers sent simulated resumes for 3 male and 3 female candidates…
