Abstract

This research aims to prove that a parallel test can be constructed by randomizing the test item numbers and or alternative answers' order. This study used the experimental method with a post-test only non-equivalent control group design, involving junior high schools students in Yogyakarta City with a sample of 320 students of State Junior High School (SMPN) 5 Yogyakarta and 320 students of SMPN 8 Yogyakarta established using the stratified proportional random sampling technique. The instrument used is a mathematics test in the form of an objective test consisting of a five-question package and each package contains 40 items with four alternatives. The test package is randomized in the item numbers' order from the smallest to the largest and vice versa. The options in each item are also randomized from A to D and vice versa. Each item is analyzed using the Classical Test Theory and Item Response Theory approaches, while data analysis is done using the discrimination index with Kruskal-Wallis test technique to see the differences among the five-question packages. The study reveals that the result of item analysis using the Classical Test Theory and Item Response Theory approaches shows no significant difference in the difficulty index among Package 1 until Package 5. Nevertheless, according to the Classical Test Theory, there is a category shift of the difficulty index of Package 2 until Package 5 when compared to Package 1 – the original package – which is, in general, not a good package, because it contains too easy items.

Abstract

This study is aimed at: (1) understanding the characteristics of Accounting Vocational Theory trial test items using the Item Response Theory and (2) determining the horizontal equation of Accounting Vocational Theory trial exam instruments. This was explorative-descriptive research, observing the subject of the eleventh-grade students. The research objects were test instruments and responses of students from six schools selected through the stratified random sampling technique. The data analysis employed review sheets and BILOG program for the Item Response Theory 2PL. The findings were as follows. (1) The test item review of test packages A and B found 37 good quality items, the Item Response Theory using 2PL showed that Package A Test generated 27 good questions, Package B Test contained 24 good questions. (2) The question equating using the Mean/Sigma method resulted in the equation of = 1.168bx + 0.270, with the Mean/Mean method resulting in the equation of  = 0.997bx - 0.250, the Mean/Mean method at 0.250, while Mean/Sigma method at 0.320.
