The purpose of this study was to empirically determine the effects of quantified violations of the underlying assumptions of parametric statistical tests commonly used in educational research, namely the correlation coefficient (r) and the t test. The effects of heterogeneity of variance, nonnormality, and nonlinear transformations of scales were…

The two objectives of this study were to compare the results of the teaching of written composition to high school students, using a problem-solving approach, with the results obtained using a traditional approach, and to determine if a problem-solving approach produces a significant difference in reflective thinking skills. Three null hypotheses…

Results of this validation study of a slightly modified version of the Coppersmith Self-Esteem Inventory substantiate its use with seventh graders to assess Goal I (concerning self-understanding and appreciation of self-worth) of the Educational Quality Assessment Program in Pennsylvania.

Utilizing data derived from two surveys (1967 and 1970) of the rural population of Novosibirsk province in the USSR, the migration plans and orientations of rural dwellers were compared with actual migration behavior to test the hypothesis that it is possible to predict migration patterns via orientation data. Three types of migration orientations…

This study examines the actual and the desired performance of school librarians in areas of planning, accessing networks, instructional and curriculum development, and production of learning resources.

Examines the importance of levels of questioning and types of feedback in designing courseware for computer-based education. Test results are analyzed for four groups of high school students who completed different versions of a computer-based science lesson, and recommendations for future research are given. (Author/LRW)

Library circulation records for five years in one Hawaiian elementary school were analyzed to discover patterns according to sex and grade level; identify titles, subjects, and types of books circulated; and determine circulation of Hawaiiana and books about Asia. Bibliography of 129 titles mentioned in text is included. (11 references) (EJS)

A descriptive model of how people make judgments under ambiguity is proposed. Two factors are reflected in the model: (1) the amount of ambiguity, which affects the size of the simulation, and (2) one's attitudes toward ambiguity. The model is tested in four experiments using individual and group analyses. (Author/LMO)

Examines thought processes closely linked with intellectual development and transcending boundaries of many disciplines. Among the topics discussed are: nonuniform change without calculus; discrimination between observation and inference; asking one's own questions; hypothetico-deductive reasoning; and types of knowledge.
