The basic assumption underlying the assessment of motor learning through mathematical analysis is that motor learning behaves exponentially when described as a function of practice time. It is assumed that motor learning will continuously taper off (minimizing errors) with increased practice and eventually approach as asympote. Although many…

A study was conducted in which the infants' behavior was allowed to control stimulus duration. A group of five infants were tested once a week from 3 through 14 weeks of age. A second group of five infants were tested once a week from 8 through 14 weeks of age. A third group of 18 infants were tested once at 3, 8, or 14 weeks of age. Once a…

Quality assurance is viewed as a means of maintaining desired performance levels during the operational use of a developed instructional program. Presented here is an analysis of the functions and the basic requirements of a quality assurance system. Procedures for implementing the system are described and discussed. The procedures include…

Results of a comparative study of F and Q tests, in a randomized block design with one replication per cell, are presented. In addition to these two procedures, a multivariate test was also considered. The model and test statistics, data generation and parameter selection, results, summary and conclusions are presented. Ten tables contain the…

Five models are introduced for the factor analytic treatment of a set of measures obtained for the same sample of persons on two different occasions. The models differ in terms of the assumptions made regarding the constancy of the (1) factor (actually component) score and (2) factor pattern matrices from occasion 1 to 2. Least-squares procedures…

A study designed to obtain information regarding vocational evaluation programs, their staff, and the vocational evaluation services they provide is presented. A survey questionnaire was constructed and distributed on a national level to facilities identified as having at least one full-time vocational evaluator. Data was analyzed with respect to…

Computational formulae for the following three tests of significance, useful in the interrupted time series design, are given: (1) a "t" test (Mood, 1950) for the significance of the first post-change observation from a value predicted by a linear fit of the pre-change observations; (2) an "F" test (Walker and Lev, 1953) of the…

The need for career education evaluation studies to integrate implementation and outcome data are examined. Various kinds of implementation and outcome data are examined. Various kinds of implementation, three analytic models, and the interpretation of data and findings are discussed. Seven approaches to solving the problem are listed. (BP)

The purpose of this study was to determine whether significant differences exist in the measured values of elementary school children in grades four, five, and six in relationship to the variables of sex, grade, parochial school and public school students, and socioeconomic level as measured by the Social Values Inventory (SVI).

It is a maxim in decision making that individuals who are affected by decisions should partake in making these decisions. The purpose of this paper is to examine practices in decision making in the field of curriculum in light of this maxim. (Author)

Seventy patients who averaged 155 percent overweight and requested jejunioleal bypass surgery as a treatment intervention for morbid obesity were studied preoperatively for prominent psychological characteristics. (Author)

Since the life change questionnaire and the A scores (physiological response) purport to measure the level of stress that is being experienced, the degree of agreement between the two measures is of importance. The present investigation compares the results of a questionnaire (Modified Schedule of Recent Events) with scores of autonomic balance…

An examination of employment trends in families with two or more workers is presented. Such families increased from 36 percent to 49 percent between 1970 and 1975. The influence of some factors such as fertility, recession and inflation, and the relation between the occupations of working parents is discussed. (EC)

Presents a model designed to allow communication analysts to predict the most promising approach to improving acceptance of a competitive service or idea. (MH)

Humphreys' comments on double-median splits (TM 504 009) are essentially correct, but are not relevant to the original Kirby and Das article (EJ 182 444). His comments do not weaken our findings. (Author/RD)
