Physics Learning Using Contextual Teaching and Learning Assisted by E-Book Android to Measure High Order Thinking Skills of High School Students

This study aims to determine the effectiveness of physics learning by using the Contextual Teaching and Learning approach with the help of Android E-book measuring the High Order Thinking Skills (HOTS) of students after being taught using the CTL-assisted Android e-book approach and find out the presentation of each HOTS indicator used. Research subjects are students of MAN Sleman 3 consisting of 32 students. The sampling technique uses purposive sampling. Data collection techniques use a description test provided during the learning process with the CTL approach in the form of Student Discussion Sheets. The results show that learning using the Contextual Teaching and Learning approach is effectively used in the physics learning process in terms of the achievement of the Minimum Competence Criteria. In addition, HOTS measurement of students through the CTL approach obtained data from 30 students, where 26 students have very high abilities and 4 students had high abilities. The average achievement of the HOTS indicator is in the "very good" category. The achievement of the ability to analyze indicators of students is in the "good" category while the ability to evaluate and create is in the "very good" category.
