The issues of treatment assignment is ordinarily dealt with within the framework of testing aptitude treatment interaction (ATI) hypothesis. ATI research mostly uses linear regression techniques, and an ATI exists when the aptitude treatment (AT) regression lines cross each other within the relevant interval of the aptitude variable. Consistent…

A multiparameter, programmable model was developed to examine the interactive influence of certain parameters on the probability of deciding that an examinee had attained a specified degree of mastery. It was applied within the simulated context of performance testing of military trainees. These parameters included: (1) the number of assumed…

Analyses of data obtained from 790 questionnaires collected from a sample of public high school seniors in a relatively low income, sparsely settled county in northern New York State in May, 1962, revealed some of the effects of 2 family systems--the immediate family and the extended family--on the migration planning of high school seniors.…

Variations in the level of female political participation were examined in the context of the "standard" model of political participation (higher socioeconomic status, urbanism, living at society's center, increased participation) and the "decline of community" model (decreased group membership, increased mobility, decline of…

Time-lapse photography was used to record the gross play activity of preschool children, rated according to three measures of equipment use and three measures of movement. The definition and derivation of these measures was outlined, and five hypotheses were presented and tested concerning the variability and interrelation of the measures.…

A Monte Carlo technique was used to investigate the small sample goodness of fit and statistical power of several nonparametric tests and their parametric analogues when applied to data which violate parametric assumptions. The motivation was to facilitate choice among three designs, simple random assignment with and without a concomitant variable…

In order for research on the educational utility of simultation games to advance, there must be some stipulation of a set of significant variables. This, in turn, requires the building of testable theoretical models and the formulation of strategic propositions to test their validity. An example of the process involved is as follows. Focusing upon…

The necessity of evaluating research methodology is discussed, and a profiling approach is proposed. Explanatory statements about the research process, directions for doing the actual profiling of the research report, a research profiling flow chart, a research profile sheet, and two additional graphic aids to understanding are included. The…

The authors offer proposals for studies of human behavior in the courtroom, with respect to communications interaction among jurors and source credibility of attorneys. They refer to innovations in videotaping procedures, which make it possible to examine communications principles and dynamics in the courtroom situation. The first proposed study…

A field study to describe common characteristics of three "most successful" vocational programs in each participating northern California community college is presented. The study was divided into distinct phases. In Phase I, a procedure for identifying three "most successful" programs on each college campus was developed and…

The effects of two social contexts on the risk -taking behavior of elementary boys on a shuffleboard task were investigated. It was predicted that Atkinson's motive-probability-incentive (M-P-I) model would be supported in the peer-competitive context, in that the success-oriented subjects would choose more goals with median Ps values than the…

Three hypotheses gave direction to this study conducted with a stratified random sample of fourth grade students. The chief purpose was exploration of the relationship between a subject's understanding of conjunctions and his reading comprehension. Another purpose was to explore the difference in the difficulty of various conjunctions. The third…

The major objectives of this study were: to determine whether information feedback provided during a difficult task would reduce State-Anxiety (A-State) and whether learner control of feedback would lead to further reductions in A-State. Another objective was to attempt to bridge cognitive and affective domains by examining relationships of the…

A program of experimental research has established a relationship between associative reaction time (RT--the time between the presentation of a verbal unit and the first association produced) and performance in verbal learning. Initial studies established that the RT value of verbal units used as response terms has a significant facilitative…

This article discusses 11 hypotheses that may explain why respect for the school as a rule-governed organization has slipped to such a low status. It suggests that improvement in student behavior may require basic changes in the ways schools are organized and managed. (Author/RK)
