Problem solving is a complex process valuable in everyday life and crucial for learning in the STEM fields. To support the development of problem-solving skills it is important for researchers and curriculum developers to have practical tools that can measure the difference between novice and expert problem-solving performance in authentic…

A new formula for the correction for chance success due to guessing was advanced and investigated, the mathematical solution of which has the property of equating the scores of fast and slow examinees of equal ability. (Author/JKS)

Four methods are outlined for estimating or approximating from a single test administration the standard error of measurement of number-right test score at specified ability levels or cutting scores. The methods are illustrated and compared on one set of real test data. (Author)

Discussion of the relationship of personality variables to programing ability highlights a study of undergraduates that investigated the influence of cognitive style on the programing skill of debugging. Use of the Group Embedded Figures Test (GEFT) is described, scoring schemes for diagnostic tasks are explained, and suggestions for further…

The purpose of this study was to determine whether it would be possible to equate rights-scored to formula-scored tests without causing a discontinuity in the meaning of the score scale. Several other subsidiary studies--of the characteristics of the two scoring methods, of nonresponse and guessing, and of reliability and parallelism--were also…

A number of strategies are described for adapting ability test items to individual differences in ability levels of testees. Each strategy consists of a different set of rules for selecting the sequence of test items to be administered to a given testee. Advantages and disadvantages of each strategy are discussed, and research issues unique to the…

Four systems for scoring student essays were used to classify eleventh grade and undergraduate students according to writing ability. The reliabilities of the raters and the validities of the systems in classifying students were emphasized. Two analytic scoring systems--which assume that quality writing is characterized by the inclusion of certain…

To improve the accuracy of college placement, Rasch scoring and person-fit statistics on the Comparative Guidance and Placement test (CGP) was compared to the traditional right-only scoring. Correlations were calculated between English and mathematics course grades and scores of 1,448 entering freshmen on the reading, writing, and mathematics…

A sample of 260 colleges was surveyed during the years 1972-1976 to determine the validity of predicting college freshmen grades from standardized test scores and high school grades using the American College Testing (ACT) Assessment Program, an evaluative and placement service for students and educators involved in the transition from high school…

Development of The Assessment of Basic Competencies (ABC), a test battery based on the three-parameter logistic model, is described. Eleven dimensions of intellectual growth are measured, from the pre-kindergarten level through ninth grade. An educationally relevant skill domain is represented by each test. Unique properties of the test, based on…
