摘要：This research aims to determine the characteristics of THOTSIC in class X chemistry material and to develop a valid and reliable package of questions.The results of PISA study in 2015 showed that the performance of Indonesian students was still relatively low.National Examination,as a benchmark for national standards,should consist of questions component with higher level thinking skills.Chemistry is a central science because it connects various other scientific fields.This is development research based on Research & Development (R & D) using the Plomp model.The results showed the average score of the material expert validator assessment was 99.27%.Limited trials consisted of 1 chemistry teacher and 10 students in class XI.Data analysis showed that teachers’response questionnaires were 4.93 as a very good category and students’were78.95% as a good category.The analysis of the reliability level of the questions was 0.62 in the high category level.The level of difficulty of the questions was 0.3 as a difficult criteria and the problem differentiator was 0.39,Dp≥0.3 = as the question was accepted.
