This study compared the convergent and discriminant validity of two confidence marking techniques with that of conventional choice testing. Achievement in vocabulary, social studies, and science (traits) was measured by a 60-item test containing true-false and 5-alternative items (methods). The test was administered to three randomly assigned groups (one for each response system), totaling 535 Ss. The results indicated very slight differences in convergent and discriminant validity that favored conventional choice testing over confidence marking techniques. 相似文献
