The End of an ERA: REQUIEM for the GLH. RIP.
Powell, J. C.
Current Scoring practices for multiple-choice tests are rooted in early Associationist Theory and are based on a two-step procedure: (1) right answers counted as ones and wrong answers are zeros, and (2) number of right answers form a total-correct score. The author contends that if either step is invalid, the use of the general linear model (GLM) after tests are scored would invalidate its results. Based on a series of studies, evidence is presented to indicate that the scoring procedures are incorrect. Invalidation on psychological grounds is based on the observation that wrong answer selection is caused by item interpretation which may lead to considering logically correct answers to be wrong. Statistical invalidation is based on the development of new procedures for interpreting contingency tables. It is suggested that present scoring procedures are not applicable for higher-order multiple choice tests and that even with low-level skills, these scoring procedures may be misapplied when the discrimination level of the test and the performance levels of the learners do not match. When systematic curvi-linearity is found, current scoring procedures are inappropriate until valid transformations for the data have been found and can be applied. (Author/MH)
