THE EFFECTIVENESS OF TEACHING BOOK BASED ON REPRESENTATION OF VERBAL PICTURES AND TABLES (R-VGT) IN BIOTECHNOLOGICAL MATERIALS TO IMPROVE STUDENTS CRITICAL THINKING

Education

The process of teaching and learning biology subjects requires teaching materials in the form of textbooks. The availability of textbooks determines the level of learning success in the classroom. Biology subjects, by some students, are still considered difficult because of the high level of complexity and character of the material. R-VGT-based textbooks are one of the books that are expected to help teachers and students make it easier to learn and understand biotechnology material that is classified as a new science in high school (SMA) learning, and the limitations of school facilities that support students and teachers to carry out learning practicum-based in the laboratory. This R-VGT-based textbook is needed for High Order Thinking Skills. The purpose of this study was to examine the effectiveness of using R-VGT-based textbooks on biotechnology material to improve the students' critical thinking skills. The method in this study was the One Shoot Case Study, with two meetings in three different classes. The data analyzed were obtained from the score of critical thinking skills by giving questions (HOTS). Then, the scores were analyzed using the Recognition method to find out the categories of students' critical thinking skills. The results of this study indicate that three schools are included in the good criteria with post-test scores respectively are 81.13 (A class); 82.03 (B class) and 81.76 (C class).
