Development of Multidimensional Computerized Adaptive Testing Program for Grade 12 O-NET Mathematics

Abstract

This research aimed to develop the item pools strategies by using interval aparameter stratification with content balancing and development of Multidimensional Computerized Adaptive Testing (MCAT) program for grade 12 O-NET mathematics. Using the O-NET mathematics exam form the National Institute of Educational Testing Service (public organization) and selecting the O-NET mathematics items from 2008-2010 and 2012- 2016 with the 3- PL item response model, which resulted in 193 items. These results indicated that the items in the O-NET item pools were in a difficult level. The Java-based MCAT system with SQL was developed based on the framework published by Reckase and Thompson and Weiss. The MCAT website system was completed and was evaluated in December, 2017 by three experts selected by Purposive sampling and 30 students selected by Convenient sampling using the Black-Box Testing method. The MCAT system was found to perform well and the feedback from the experts and students was satisfactory and positive.
