Development of The Thermochemistry- Hots-Tawheed Multiple Choice Instrument

This research is part of the development research in thermochemistry-hots-tawheed teaching materials. the purpose of this research is to develop the thermochemistry tawheed High Order Thinking skills (HOTs) test instrument. the stages of the research began by designing 45 multiple choice items with five options. The instrument assessed by three science education experts, and pilot tested to 56 chemistry students. analysis of the test items was carried out using the rasch measurement model approach, the multiple choice test analyzed with winsteps software, and expert validation analyzed using facets software. Multirater validation test results showed 27 of 45 test items were in good quality (60%) according to the experts. The multiple choice items results : (1) the reliability of the test items was good quality (reliability index 0.89); (2) test of item fit, 34 out of 45 test items are good in fit statistics indices (75.6%); (3) person map item test, showing difficulty level, easy: medium: difficult = 50%: 33%: 17%; (4) the test distractor work well for 23 of the 45 test items (51%); (5) there are 19 of 45 valid test items based on pilot tested results that are in accordance with expert judgment.
