The Self-Description Questionnaire III (SDQ III) was designed to measure 13 factors of self-concept. The reliabilities of the factors were high, and correlations among them were low. Academic achievement measures in language and mathematics were correlated with self-concepts in the same areas but not with other self-concept factors. (Author/DWH)

Results of the investigation suggest that the facet-factorial approach can be an effective technique for the construction of rating scales to measure complex behavior such as music performance. (Author)

This paper assesses the reliabilities of the items and dimensions, determines the extent of agreement among raters, identifies the factor structure, and assesses the influence of sex and age of children on raters' perceptions on a short form of the Teacher Temperament Questionnaire. (Author/PN)

Cognitive holding power is defined as a characteristic of the learning setting that presses students into different kinds of cognitive activity. Development of an instrument to measure cognitive holding power and studies of the instrument's reliability with over 1,500 Australian technical college students are reported. (SLD)

Empirical results from two studies--a simulation study and an experimental one--indicated that, in achievement data of the problem-solving type where a specific subject matter area is being tested, the greater the variety of the algorithms used, the higher the dimensionality of the test data.
