Eight different methods are reviewed for determining whether two or more tests are equivalent measures. These methods vary in restrictiveness from the Wilks-Votaw test of compound symmetry (which requires that all means, variances, and covariances are equal), to Joreskog's theory of congeneric tests (which requires only that the tests are measures…

A relatively simple procedure for modeling periodic components in time series data is presented in this paper, along with an example of the procedure's use with communication data. Similar to multiple regression analysis, the described procedure has four steps that are based on information about periodic waves and their components, how to create…

AFTER A BRIEF SUMMARY OF THE TEST PROGRAM (DESCRIBED MORE FULLY IN LI 000 318), THE STATISTICAL RESULTS TABULATED AS OVERALL "ABC (APPROACH BY CONCEPT)-RELEVANCE RATIOS" AND "ABC-RECALL FIGURES" ARE PRESENTED AND REVIEWED. AN ABSTRACT MODEL DEVELOPED IN ACCORDANCE WITH MAX WEBER'S "IDEALTYPUS" ("DIE OBJEKTIVITAET…

FIFTY DISADVANTAGED CHILDREN, RANGING IN AGE FROM 33 TO 56 MONTHS, PARTICIPATED IN A 7-MONTH PRESCHOOL EDUCATIONAL PROGRAM DESIGNED TO IMPROVE THEIR LANGUAGE AND SOCIAL SKILLS. THE ILLINOIS TEST OF PSYCHOLINGUISTIC ABILITIES, THE PEABODY PICTURE VOCABULARY TEST (FORM A), AND THE VANCE LANGUAGE SKILLS TEST MEASURED THE CHILDREN'S DEVELOPMENT IN…

A method to calculate the need for academic staff per faculty, based on educational programs and numbers of students, is described which is based on quantitative relations between programs, student enrollment, and total budget. The model is described schematically and presented in a mathematical form adapted to computer processing. Its application…

Employing a background information questionnaire, a policy preference scale, and the Kluckhohn Value Orientation Scale, 40 American Indian tribal leaders and 35 Anglo administrators from 4 North Dakota reservations were surveyed to explore preferences for problem-solving approaches in the field of child welfare. The following hypotheses were…

Data derived via questionnaire from a black and white female subsample (N=1,670) of Louisiana high school seniors were utilized to test eight hypotheses which addressed the relationship between athletic participation and female achievement orientations. School type (public-parochial), residence (rural-urban), and school size (large-small) were…

When repeated measures are obtained on the same subjects, interobservation dependencies frequently are generated. The major ways in which these dependencies can arise are illustrated and it is shown how these dependencies may invalidate the use of analysis of variance (ANOVA) and its extension, trend analysis, as methods of evaluating the data of…

Two educational computer simulations are described in this paper. One of the simulations is STATSIM, a series of exercises applicable to statistical instruction. The content of the other simulation is comprised of mathematical learning models. Student involvement, the interactive nature of the simulations, and terminal display of materials are…

This research tests the implicit assumption that cognitive development is independent of ethnic background. The testing instrument used was a newly designed spatial reasoning test intended to reflect the sequence of acquisition of skills requisite to map reading and drawing. A sample of 270 black, Chinese, and white subjects (90 each at the 5th,…

The purpose of this study was to compare male high school seniors who are talented in mathematics with male high school seniors who are talented in English as to sense of responsibility, level of anxiety, and sociability. The following hypotheses were tested: (1) No difference will be found in levels of responsibility between male high school…

A study was conducted to explore some of the relationships existing between the early behavior of a change agent with a group client system and its subsequent effects on the helping relationship established between them. A review of related literature was made. The model of helping relationship which formed the basis for the design of the study…

The influence of participation in adult basic education on attitudinal changes among a selected group of adults from rural Appalachia was studied. Specific aims of the study were: (1) to determine the relationship between participation in ABE and change in anomia, (2) to determine the extent of anomia among rural Appalachian adults with…

The model described in this paper for the teaching of beginning shorthand through the use of computer-assisted instruction attempted to prevent incorrect responses from occurring during the acquisition of correct responses to beginning shorthand symbols. (Author)

This study was designed to test the following hypothesis: no significant differences will exist in the responses to a questionnaire by student teachers and supervising teachers assigned to two different programs of student teaching--one large group and two small groups. The control program was the normal program of supervision that is typically…
