This paper emphasizes the need to go beyond structural models of personality and intellect to develop sequential models of psychological process, particularly for such complex phenomena of prime concern to theory and application as learning, problem solving, and creativity. It is further argued that factor analysis, in a multitude of studies of…

Decisions concerned with the use of alternative Air Force training methods require several types of data. Among these are capacity to train, cost of the training, and quality of the trained airmen. The two methods of formal training in the Air Force are on-the-job training (OJT) and technical school training. The data currently being provided to…

Violations of four selected principles of writing multiple-choice items were introduced into an undergraduate religion course mid-term examination. Three of the flaws significantly increased test difficulty. KR-sub-20 values were lower for all of the tests containing the flawed items than for the "good" versions of the items but significantly so…

The harmonic mean and Kramer (1956) unequal n forms of the Tukey multiple comparison statistic were investigated for Monte Carlo Type I and Type II errors under conditions of assumption violations. The two major questions concerning the sensitivity of multiple comparison statistics for different types of pairwise contrasts and the affect of…

A new form of the Purdue Elementary Problem Solving Inventory which presents real-life problem situations as three-dimensional models is described and developmental data is presented. Second and fourth graders in an advantaged and a disadvantaged school were given either the model version or the original slide version of the Inventory. The model…

The two purposes of this investigation were to study the effects of variance heterogeneity on three selected multiple comparison procedures and to determine if either of two nonstandard methods would be superior to the conventional methods based on mean square within. The three procedures studied were the Wholly Significant Difference Test (WSD),…

The development and evaluation of a system for designing instructional plans and resource patterns for those plans are described. Development of the system, which was in three stages, was based on the premise that decisions concerning efficient allocation of resources and the use of resources for effective instruction cannot realistically be made…

Using the grade equivalent composite scores on the Iowa Tests of Basic Skills of Iowa fourth grade public school pupils who took the tests in January 1970, a study was made to determine the relative precision with which an estimate could be made of the individual percentile norms from different types of cluster sample designs. Five scores ranging…

The final volume of The Study of Junior Colleges contains the measurements and instrumentation derived from the project for future evaluation surveys. Part One, Prediction of Student Outcomes: Multivariate Analysis of the Survey Data, provides: an introduction to the analyses; data reduction, factors, and scales; students' objectives and…

Two studies were done to examine aggressive behavior in humans. In Experiment One, adults working on a plunger pulling task could receive a 3.5 ma shock at 75% probability every two minutes. The shock was unrelated to their plunger pulling behavior. Subjects could press a toggle switch to deliver electric shock to the experimenter, who was in the…

An exploratory study into the bias associated with faculty self-reporting of time and effort is reported. The paper delves into the question of whether or not there is bias in faculty reports of time and effort and whether a pattern to any such bias might appear. The methodology for conducting the study involved gathering faculty estimates of…

Programs in Michigan, North Carolina, and Oklahoma, under the Vocational Rehabilitation Act were reviewed by the General Accounting Office to determine the ability of the programs to meet the needs of all handicapped persons and their effectiveness in helping individual handicapped persons. Under the act, before vocational rehabilitation services…

This paper describes and illustrates the use of a recently developed management simulation-information model, suggesting it as one possible step toward partial solution of two longstanding concerns in educational administration. These problems are (1) the myopic and parochial "problems" view of education and (2) the schism between professor and…

In measuring attitudes by Semantic Differential, bipolar adjective scales with high loadings on an evaluative factor derived by Principal Components Analysis are used typically as unidimensional attitude measures. Komorita and Bass, using conventional statistical techniques, report the discovery of more than one evaluative factor. This paper…

The study focuses upon preparation programs of graduate students who aspire to become school principals. The design of the study is experimental with differing curriculum patterns for the principalship being the independent variable and potential placement of candidates the dependent variable. The method employed is unique inasmuch as controlled…
