Profile of Senior High School Metacognitive Ability in Solving Problems of Abstraction on Physics Material

This study aims to determine the ability of students’ metacognition in solving abstract problems in physical material. The study involved students who took through the test. Metacognition ability data obtained through written test consisting of questions metacognitive knowledge and metacognition skills. Data analysis is done descriptively. The result of the research shows that declarative knowledge dominates students metacognition knowledge, that is students can recognize the difficult problem and able to interpret in other forms but less able to recognize method used and how to finish, while students' metacognition skills are more dominant in planning and monitoring fields. Prediction and evaluation skills are still relatively low. Overall, metacognition ability of students included in the low category

Development of Worksheet Based on High-order Thinking Skills to Improve High-order Thinking Skills of the Students

This research aimed to develop high order thinking skills workheet in momentum, impulse, and collision topic for senior high school This type of research is Research and Development follow 4D models, includes : define, design, develop and disseminate. Data collection instruments used validation sheets for given to 5 validator, Aspects assessed include graphic, presentation, language, and the contents of workheet. Based on the result of data analysis showed that all aspects got average score in the range of 3.4 to 4 with categories of very high. Thus, high order thinking skills was valid. For the purposes of testing the worksheet is given on 68 students. to measure the effectiveness of worksheet used Higher Level Thinking Ability Test that amounts to 12 items. Based on the result of data analysis indicate, There is difference of higher order thinking skill of students who use HOTS worksheet than who are not use HOTS worksheet, where the average Higher Order Thinking Skill on students who use HOTS worksheet highe
