The purpose of this study was to determine the effects on test scores of employing a separate answer sheet using the California Test of Mental Maturity with 117 pupils in the primary grades of one through three. The CTMM was administered twice to all students; once employing the usual answer marking format contained in the test booklet and once employing a separate answer sheet. A counterbalanced design was used to control for order effects. The mean raw differences between marking format conditions decreased from 23.67 to 10.79 to 3.32 for students in grades one through three respectively, indicating that the need for the test booklet marking format decreases sharply as the grade level of the Ss increases. 相似文献
