Purpose of this study was to examine the effects of the true change-true initial score correlation on one aspect of the true simple change estimate, namely its error variance. (Authors/CB)

The most consistently used scoring system for the rod-and-frame task has been the total number of degrees in error from the true vertical. Since a logical case can be made for at least four alternative scoring systems, a thorough comparison of all five systems was performed. (Author/CTM)

Forty adolescent subjects with behavior problems at home or at school were administered the Woodcock Reading Mastery Tests. Subjects ranged in age from 12 to 18, and included 25 males and 15 females. The Passage Comprehension Test for each subject was rescored using three different ceiling criteria: (1) five errors in six consecutive responses,…

It has been shown that Guttman weighting of test options results in marked increases in the internal consistency of a test. However, the effect of this type of weighting on the structure of the test is not known. Hence, the purpose of this study is to compare the factor structure of Guttman-weighted and rights-only-weighted tests and to relate the…

Reports the results of several test-reliability experiments which compared a modified confidence weighted-admissible probability measurement (MCW-APM) with conventional forced choice or binary type (R-W) test scoring methods. Psychometric properties using G theory and conventional correlational methods are examined, and their implications for…

A simulation study was designed to assess the severity of regression effects when a set of selection scores is also used as pretest scores as this pertains to RMC Model A of the Elementary and Secondary Education Act Title I evaluation and reporting system. Data sets were created with various characteristics (varying data reliability and…

To assess the impact of various rating scale formats in rating student teachers, a Likert-type scale (Highly agree/slightly agree/neither/slightly disagree/highly disagree) was derived from the graphic scale currently used by the cooperating teachers and university supervisors. They rated the music student teachers on an eight-point scale from…
