A Comparative Analysis of Mathematics Placement Test Using Item Response Theory.
Obiekwe, Jerry C.
The first purpose of this study is to do a comparative analysis in terms of the item difficulty and discrimination index between Mathematics Placement Test Form A and G. The results seem to suggest that items on both forms of the placement test are equally difficult. However, items on form A appear to have more discrimination power than items on form G. Perhaps form A should be used more frequently than form G in making math placement decisions. The second purpose was to determine a subset of items from form A that can better predict students' success in mathematics classes. The third purpose was to determine a subset of items from form G that can better predict students' success in mathematics classes. Those items whose item discrimination power were greater than 1 were the reliable items. The identified reliable items can be used exclusively or they can be weighted more and then used in conjunction with the less reliable items in placing students into math classes. This process, perhaps, may guard against placing students into classes where they do not belong. (Contains 17 references.) (YDS)
