Videoscribe with Mastery Learning to Improve Critical Thinking Skills and Learning Interest of Vocational High School Students in Geometry

Mathematical critical thinking ability is a process of thinking by recognizing and analyzing something to formulate an answer or find a solution. The importance of mathematical critical thinking is to help students to be able to identify, analyze and solve the problem/question creatively and logically so as to produce the right decision. The research method used is convergent. The sample in this study were students of class XI Multimedia at SMK Mahaputra, Bandung Regency. The critical thinking ability test instrument given was 6 questions accompanied by a learning interest questionnaire, observation sheets and interviews with each student. Then the results obtained were analyzed descriptively and inferentially. The results show that students who receive learning using videoscribe products through mastery learning show better results than students who receive conventional learning. This study shows that learning using videoscribe products through a mastery learning approach is more effective in improving mathematical critical thinking skills of class XI Multimedia students at SMK Mahaputra, Bandung Regency compared to conventional methods, because this approach facilitates students in analyzing and solving problems logically and creatively. These findings reinforce the importance of using interactive media and learning strategies that are oriented towards mastery of the material, so that they can be considered in developing more adaptive and technology-based mathematics learning methods.
