Physical Learning Using Model Direct Instruction Assisted Application Plickers to Measure the Understanding of the Concept of Students

This research is a quantitative research that aims to determine the effectiveness of physics learning by using a direct instruction model assisted by the Plickers application, knowing the students 'understanding of the concept after being taught using a direct instruction model assisted by the Plickers application, and knowing the percentage of students' achievement for each understanding concept. The research subjects were students of class XI MIA 1 Sayegan 1 State High School consisting of 32 students and were selected using a purposive method. Data collection techniques were carried out using multiple choice test instruments presented in the Plickers application. The results showed that learning using direct instruction learning models assisted by the Plickers application was effectively used in the physics learning process in terms of the achievement of the KKM. In addition, the average understanding of students' physics concepts is 80.00 with a total of 27 people in the high category, 5 people in the medium category, and no students in the low category. Furthermore, the percentage of each concept understanding concept is in the high category and only one indicator is in the medium category with a percentage of 77%.
