Making of Test Instrument Based Higher Order Thinking Skills on Basic of Mechanics and Heat

. This study aims to determine the quality of appropriateness products of test instruments based Higher Order Thinking Skill (HOTS) on Basic of Mechanics and Heat based on the Expert Team. The research method used in this study is Research and Development (R&D) methods. The stages that will be carried out are: (1) preliminary study; (2) development study. In the preliminary stage is to study the learning tools, especially on the learning achievement of subjects and mid-semester exam questions and the final semester questions, where it is found that the learning achievement is still oriented towards Low Order Thinking Skill as well as mid-semester exam and final semester exams are still oriented towards low-level thinking. The next step is to conduct a development study by changing the achievement of learning oriented HOTS. Next, make a test instrument lattice based on learning achievement as a reference for making test instruments. From the results of the test instrument products that have been made then validated by two experts from the Department of Physics. From the results of the validation by the expert team, in general the test instruments were made in good categories according to HOTS criteria.
