This report addresses the problem of sample size in developing prediction equations for college freshman grade averages under the American College Testing (ACT) Assessment Program. For the ACT Assessment, the prediction weights are estimated by standard least squares procedures. Because prediction weights are estimated regression coefficients…

In 1986, a study was conducted by the Rancho Santiago Community College District (RSCCD) to evaluate the relationship between reading placement scores and classroom performance. The study sample consisted of students from fall 1985, spring 1986, and fall 1986 who had been tested using the College Board Assessment and Placement Test upon…

With the proliferation of suicide prevention centers in the United States, the task of rapidly and effectively assessing an individual caller's suicide potential has become an important research problem. However, the social science researcher is often confronted with an ethical problem when the results of his predictive equations can be used to…

Results are described for the first two phases of a study to develop and evaluate models of student progress in a technical training course being offered in a computer managed instructional environment at Lowry Air Force Base, Colorado. Several categories of models were developed in Phase I and defined by model type and by the type of variables…

Studies were conducted to determine whether measures of intellectual merit that are used as criteria for admission to the University of Karachi in Pakistan have predictive validity. The predictive validity of the intermediate examination score was studied with recent graduates of the pharmacy, medicine, and engineering schools. Additional studies…

Least squares and Bayes methods were used in a cross validation study conducted for comparison purposes. The study applies to situations with the following conditions: predictor data are given on the same scales; criterion data may be given on different scales; and it is necessary to pool data even though criterion scale differences exist. Such a…

This paper presents evidence bearing on the predictive validity of the College Board (CEEB) Achievement Average--defined as the arithmetic mean of all Achievement Test scores included on a candidate's CEEB Admissions Testing Program score report and now routinely reported to colleges--for women students in several liberal arts colleges. The…

A procedure for predicting categorical outcomes using categorical predictor variables was described by Moonan. This paper describes a related technique which uses prior probabilities, updated by joint likelihoods, as classification criteria. The procedure differs from Moonan's in that the outcome having the greatest posterior probability is…

From some simple and schematic assumptions about information processing, a stochastic differential equation is derived for the motion of a student through a computer-assisted elementary mathematics curriculum. The mathematics strands curriculum of the Institute for Mathematical Studies in the Social Sciences is used to test: (1) the theory and (2)…

Alternate admission systems are reviewed in respect to the minority applicant in an attempt to assess the nature of the bias frequently referred to in connection with standardized testing. The connection between the use of the Graduate Record Examinations (GRE) as a standardized test and the admission system was explored, concluding that the role…

Evaluated the Wechsler Intelligence Scale for Children-Revised (WISC-R) as a tool for understanding children's learning problems. Analyzed the predictive utility of several WISC-R subtest recategorizations with regard to academic achievement for 105 children referred for psychoeducational evaluation because of classroom learning problems. Stepwise…

A retrospective study was performed to determine whether graduates of a baccalaureate program in nursing who failed or were within a chance level of failure on the National Council Licensure Examination could have been identified as "risk" students during their undergraduate nursing program from data that are routinely collected.…

Examines the importance of levels of questioning and types of feedback in designing courseware for computer-based education. Test results are analyzed for four groups of high school students who completed different versions of a computer-based science lesson, and recommendations for future research are given. (Author/LRW)

This study examined the predictive validity of the Coopersmith Self Esteem Inventory with adolescents relative to each of the criterion measures representing communication satisfaction toward each parent and feelings toward each parent, and the differential validity of the self-esteem, communication satisfaction, and feelings toward each parent…

An investigation of study habits of 540 Australian college sophomores casts doubt on the validity of one model and suggests some adjustments in it. The relationship of study habits to subject area, age, and sex, and the model's usefulness in predicting academic achievement are examined. (MSE)
