Applications to the Promax Rotation are discussed, and it is shown that these procedures solve Thurstone's hitherto intractable "invariant" box problem as well as other more common problems based on real data. (Author/RC)

This report series defines and measures the "information activity" within the national economy. "Information activity" is defined to include those specific industries and occupations whose primary function is to produce, process, or transmit economically valuable information. This volume consists of input-output tables showing…

The document recounts in a narrative scenario how fictional nursing teachers and a consultant in a work-session developed a matrix which helped the teachers organize their clinical nursing courses more effectively by discriminating carefully among knowledge, performance, and attitude objectives. Placing the objectives on the matrix revealed the…

Part and bi-partial canonical correlations were developed by extending the definitions of part and bi-partial correlation to sets of variates. These coefficients may be used to help researchers explore relationships which exist among several sets of normally distributed variates. (Author)

This report describes the results of preliminary work by the Human Resources Research Organization to develop a comprehensive theory for structuring subject matter. The report focuses on the first three of five components that any comprehensive model of instruction should include: (1) a representation of the subject matter to be taught; (2) a…

The paper describes the task matrix procedure for determining the task content for work samples in entry-level occupations within a specified occupational group or industry. The procedure enables the work sample developer to systematically obtain and organize task information from the Dictionary of Occupational Titles in order to identify those…

Order analysis is a measurement technique for the quantitative and generalizable description of complex structures. Relations between the manifest elements of a data matrix and its underlying latent entities and attributes are considered in terms of magnitudes as basic scale units. Magnitude is conceptualized as a difference relation, translated…

This paper presents several aspects of task analyses for maintenance jobs when these analyses are used as bases for the development of Job Performance Aids (JPAs) and job oriented training. It starts with a brief history of the development of task analysis technology and the part that Air Force research has played in this development. The fact…

Beginning with the results of Girschick on the asymptotic distribution of principal component loadings and those of Lawley on the distribution of unrotated maximum likelihood factor loadings, the asymptotic distributions of the corresponding analytically rotated loadings is obtained. The principal difficulty is the fact that the transformation…

This twenty-fourth unit in the SMSG secondary school mathematics series is the teacher's commentary for Unit 23. For each of the chapters in Unit 23, a time allotment is suggested, the goals for that chapter are discussed, the mathematics is explained, some teaching suggestions are given, and answers to exercises are provided. In the appendix is a…

Suggests 11 dimensions of cognitive style which influence learning, and proposes a three-step instructional design plan to move beyond individual instruction to individualized instruction, so that differences in learners need not result in differences in learning. (Author/JEG)
