DEVELOPMENT OF STUDENT WORKSHEET WITH GUIDED DISCOVERY ORIENTED TO TRAIN HOTS ON THERMOCHEMISTRY MATTER
This research purpose to describe the feasibility of student worksheet with guided discovery oriented to train HOTS on thermochemistry matter. Research methodology that used was research and development which consist of 10 stages, but this research is limited to product trial stages. The result shows that student worksheet is feasible on validity aspect which viewed from content and construct validity. The content validity get percentage of 85.76% for student worksheet 1 and 85.91% for student worksheet 2. The construct validity obtained percentage of 87.16% for student worksheet 1 and 2. Practicality aspect is viewed from student responses that get percentage in range 75-100% and observation of students activities shows overall relevant activities are greater than irelevant activities. Effectiveness aspect is viewed from student’s HOTS test result that get gains score in range 0.58-0.96 with medium (21.875%) to high (78.125%) criteria and knowledge domain test result with >80% of classical completeness
