At Illinois College of Optometry a peer-review committee evaluates the exams of both basic science and clinical courses to provide an objective means of evaluating a faculty member's teaching ability. Five aspects of the exam (content, construction, statistical analysis, adjusted questions, instructor's rationale) are evaluated to determine the…

Medicine and epidemiology currently dominate the study of the strong association between socioeconomic status and mortality. Socioeconomic status typically is viewed as a causally irrelevant "confounding variable" or as a less critical variable marking only the beginning of a causal chain in which intervening risk factors are given prominence. Yet…

Researchers studying monitoring accuracy currently use two different indexes to estimate accuracy: relative accuracy and absolute accuracy. The authors compared the distributional properties of two measures of monitoring accuracy using Monte Carlo procedures that fit within these categories. They manipulated the accuracy of judgments (i.e., chance…

Structural equation modeling (SEM) refers to a family of statistical techniques that explores the relationships among a set of variables. Structural equation modeling provides an extremely versatile method to model very specific hypotheses involving systems of variables, both measured and unmeasured. Researchers can use SEM to study patterns of…

In the scientific literature, the debate around the school and class effect is polarized, because the variance between schools and classes is explained either by school and class process or by group composition. The first aim of this article is to shed light on this debate and move beyond it by reviewing qualitative and quantitative studies…

The study evaluated the comparability of two versions of a teacher certification test: a paper-and-pencil test (PPT) and computer-based test (CBT). Standardized mean difference (SMD) and differential item functioning (DIF) analyses were used as measures of comparability at the test and item levels, respectively. Results indicated that effect sizes…

The problem of determining optimal test lengths with fixed total testing time has proved to be a difficult one for criterion-referenced test developers. An algorithm is needed which can be used by test developers to allocate available testing time to maximize the validity of their total criterion-referenced tests or testing programs. To be…

Meta-analytic research techniques were used to compare the General Aptitude Test Battery (GATB) validities of blacks and non-minorities. The sample consisted of 7,854 black and 15,769 non-minority subjects from 113 Specific Aptitude Test Battery (SATB) validation studies analyzed since 1972. The first approach was to compare average validities…

Six methods of equating Test of English as a Foreign Language (TOEFL) test scores for samples consisting of the usual groups of examinees and groups controlled for native language representation were evaluated in terms of scale stability. The equating methods included three item response theory (IRT) variants (fixed b's scaling, a one-parameter…

THE PATTERN OF PREDISPOSITIONAL AND MEDIATIONAL FACTORS RELATING TO DIFFERENTIAL MATERNAL SUCCESS IN COPING WITH THE CRISIS CREATED BY FATHER ABSENCE IN MILITARY FAMILIES WAS EXAMINED. MOTHERS IN 23 FAMILIES WHOSE HUSBANDS WERE ABSENT ON EXTENDED MILITARY TOURS, WERE ADMINISTERED AN EXTENSIVE BATTERY OF SOCIOMETRIC AND PSYCHOLOGICAL TESTS PRIOR TO…

THE PRIMARY PURPOSE OF THIS EXPERIMENT WAS TO DETERMINE WHETHER HIERARCHICALLY DIFFERENTIATED GROUPS WERE AS PRODUCTIVE ON PROBLEM-SOLVING TASKS AS HIERARCHICALLY UNDIFFERENTIATED GROUPS. THE EXPERIMENT ALSO INVESTIGATED THE EFFECTS OF FORMALLY BASED STATUS DIFFERENCES ON GROUP EFFICIENCY AND RISK-TAKING. TWENTY GROUPS CONTAINING FOUR SUBJECTS…

In a study to determine factors which cause or inhibit change in a school organization, 30 schools in five Western States were classified according to degree of innovativeness and organizational climate. Correlations were determined by analyzing four selected variables: Expenditures per student, age of staff, years of staff service, and size of…

Employing similar variables, along with an assessment of the participation-aspiration hypothesis for athletes residing in rural Louisiana, a partial replication was attempted of previous studies of the athletic participation-aspiration relationship. A further extension of past studies was made by assessing the effects of selected predictor…

The major objective of the Carroll County Competency Based Teacher Certification (CBTC) Project is the development of a system for the recertification of teachers with classroom experience. A major goal is the development of a model for the identification and measurement of teacher competency areas; and the assessment of the extent to which these…

This explanatory booklet and the materials that accompany it have two major purposes. The first purpose is to provide local school officials with information regaing the performance on basic skills achievement of each student who took the 1971-72 Michigan Educational Assessment Battery. The second purpose is to provide local officials with…
