Predictive validity, generally taken to be the prime validity that occupationally normed interest inventories should demonstrate, is dependent on the capacity of an instrument to differentiate between occupations. A comparison of two methods of differentiation shows that a method using proportions of each occupational group to assign item-scoring…

The predictive analysis approach to adaptive testing originated in the idea of statistical predictive analysis suggested by J. Aitchison and I.R. Dunsmore (1975). The adaptive testing model proposed is based on parameter-free predictive distribution. Aitchison and Dunsmore define statistical prediction analysis as the use of data obtained from an…

Several analyses are presented on the relationships among the Test of Spoken English, Test of Written English, and Test of English as a Foreign Language. The multivariate prediction of each test from the scores on the others is very accurate; variances with two prominent factors may relate to specific cognitive test-taking skills. (eight…

The predictive and incremental validity of the New Medical College Admission Test (New MCAT) Science Problems Subtest was examined with a sample of over 165 medical students. Criterion measures were National Board of Medical Examiners (NBME) Part I (basic science) and Part II (clinical science) performance. The Science Problems subscore is derived…

This paper reports the results of using a three-layer backpropagation artificial neural network to predict item difficulty in a reading comprehension test. Two network structures were developed, one with and one without a sigmoid function in the output processing unit. The data set, which consisted of a table of coded test items and corresponding…

This report was written to provide guidance in the development and evaluation of alternative instructional approaches that hold promise of improving instructional effectiveness. The main focus of the report is on how to identify and test interactive relationships between individual differences among learners and instructional conditions or…

The 4th International Conference on Educational Data Mining (EDM 2011) brings together researchers from computer science, education, psychology, psychometrics, and statistics to analyze large datasets to answer educational research questions. The conference, held in Eindhoven, The Netherlands, July 6-9, 2011, follows the three previous editions…

The composite of Armed Services Vocational Aptitude Battery (ASVAB) subtests used to select applicants for entry-level training in Army clerical schools was evaluated by correlating composite scores with training performance scores. Comparisons were made between the multiple R for this optimal set of predictors and that for the composite of…
