| مستخلص: | Two types of classification error are possible in competency tests: erroneous classification of an individual as a "master" of the subject (Type II error), and erroneous classification of a master as a "nonmaster" of the subject (Type I). If steps are taken to minimize Type II errors, an artificially high number of true masters will be classified as nonmasters. The remedy for this problem is to empirically correct for incorrect answers caused by irrelevant factors (fatigue, lack of motivation, etc.). This is done by self-correction: administering the test, checking it, and resubmitting the incorrectly answered questions to the student. The examinee is allowed to correct those incorrect answers. The self-correction technique was used in testing some 4,000 third-grade students in 80 elementary schools in Israel. Forty-one open-ended mathematics questions were answered and corrected. Seventy percent of students with incorrect answers provided correct answers when retested. Based on this finding, the probability of misclassification of true masters as nonmasters (Type I error) was calculated to be 40%. Further analysis showed self-correction to increase the test's internal consistency and its replicability. Retesting two weeks later provided nearly identical results. (MGD) |
