The development and evaluation of prototype hands-on equipment, job sample performance tests for a high skilled technical Military Occupational Specialty (MOS) are described. An electronic maintenance MOS (26C20) was used as the research vehicle. The results led to the conclusion that valid and reliable performance tests could be constructed, but…

This report presents the final scope, methods, and results of the evaluation of proficiency measures in occupational therapy. The intended purpose of the investigation was to evaluate and analyze the reliability and validity of measurements that are predictive of competence and proficiency at entry levels in occupational therapy. Each level of the…

This paper describes by illustrative examples from therapeutic encounters the nine stages of an Intrapersonal Exploration (DX) scale. It is a revision of an earlier scale, based upon the theoretical conception of intrapersonal exploration as a sufficient antecedent condition for constructive personality change in psychotherapy. The scale is…

Relatively few research studies on the determinants of academic achievement focus on the exchanges that take place within the classroom as a social system. This paper focused on such exchanges and on the research of Coleman (1966) and of Rosenthal and Jacobson (1968). (Author/RK)

Two multiple choice forms of two cloze reading tests were developed from responses to the cloze forms by college undergraduates. These tests were investigated using the original keys, empirical keys, and option weighted keys. Reliability and validity data are reported. (Author/JKS)

The standard growth expectations for various levels and categories of the Quarterly Profile Examination were reported in this study as an approach to assessing edumetric validity. The results demonstrated the usefulness of computing standard growth expectations for tests used in the measurement of within-individual growth. (Author/JKS)

For each of two revised forms of the Dimensions of Self-Concept measure (intermediate and secondary forms), statistical information is presented concerning the intercorrelations of each of five factor scales, the reliability and standard error of measurement of each scale, and the results of item analyses. (Author/JKS)

The decline in test scores is demonstrated to be a result of changing philosophical attitudes toward tests and learning. It is suggested that traditional standardized tests may no longer be appropriate. (JMF)

A Behavior rating scale, usable for parents and teachers, was devised to measure overt behavioral characteristics of children with learning disabilities. (SBH)

The focus here is on category observation instruments which typically record classroom behaviors in the form of tallies, checks, or other marks which code them into predefined categories and yield information about which behaviors occurred and how often they occurred during the period of observation. Discusses the essential properties of the…

A multiple true-false item is one where a testee has to identify statements as true or false within a cluster (of two or more) of such statements. Clusters are then scored as items. This study showed such a procedure to yield less reliable results than traditional true-false items. (JKS)

The feasibility of measuring responding desirably with attitude-opinion items is discussed, and an index based on 16 such items is presented. Estimates of reliability and validity for this index, and examples of its use as a covariate (control) in attitude research are presented. Similarities and differences from related scales are discussed.…

An instrument used to assist teachers in the prescription of appropriate print size for the partially sighted student, the Teacher's Evaluation for Low Vision Needs, was field-tested for reliability with 54 legally blind and partially sighted students (7-14 years old) who used large print books. (Author/DLS)

Textbook calculations of statistical power or sample size follow from formulas that assume that the variables under consideration are measured without error. However, in the real world of behavioral research, errors of measurement cannot be neglected. The determination of sample size is discussed, and an example illustrates blocking strategy.…

The results of initial validity and reliability studies on the Rational Behavior Inventory are presented. The instrument was developed to be used for assessment, treatment planning, and evaluation of clients by counselors who use Rational Emotive Therapy. (Author/JKS)
