TEST ITEM ANALYSIS PROGRAM DEVELOPMENT WITH RASCH MODELudONE PARAMETER FOR TESTING THE ITEM DIFFICULTY LEVEL OF udMULTIPLE-CHOICE TEST USING BLOODSHED DEV C ++ APPLICATIONS

摘要

This article was made in Item Response Theory lecture to improve the ability ofudstudents to learn the application of the theory of grain analyst using the model of Raschudmodel. This article is aimed to get a test item analysis program with Rasch model oneudparameter for testing the item difficulty level of multiple-choice test and to determine theuddistribution of the item difficulty level of the test which is analyzed using the result programudof the development. The development of test item analysis program were performed using 4Dudmodels which is consist of define, design, develop and disseminate. The results of programuddevelopment named RASCHAM. RASCHAM using Item Response Theory (IRT) whichudadapt the Rasch model one parameter. Based on the result of validation from four validators,udthe test item analysis program judged worthy used for test item analysis. Based on testingudperformed by comparing the analysis results of the QUEST can be concluded that theudaccuracy of RASCHAMprogram reached 92.80%. The analysis results of the item difficultyudlevel with RASCHAM on the odd semester of final examination test items of the physicsudsubjects from XI class of 2th Wonosari State Senior High School academic year 2013/2014 inudGunungkidul for code A is about 7.5% with a very easy category, 12.5% easy, 25%udmoderate, 47.5% difficult, 2.5% very difficult and 5% not good. While for code B is aboutud12.5% with a very easy category, 32.5% easy, 45% moderate, 45% difficult, 2.5% veryuddifficult and 2.5% not good.
