Guided discovery learning to improving triangular understanding in blind student

The purpose of this study is to study Guided Learning in improving the understanding of blind students. This research is an experimental study with the design of Single Subject Research (SSR) A-B. Students who were used as subjects in this study were students of class VII MTs Yaketunis Yogyakarta. Data collection through tests, observations, and interviews. Data analysis was performed based on results in the baseline phase or interventions that were appropriate for the conditions, namely in conditions and between conditions. This can be seen from the increase in student test results in the initial phase with scores of 43, 41 and 50 to 80, 83, 81, and 90 in the intervention phase. Thus, the conclusion with the results of the analysis in the phase that shows the intervention phase has a direction and direction greater than the basic phase. Through observations and interviews, it is also recognized the consistency of the answers which shows the understanding of students' perspective has been constructed. With discovery-guided learning, students can not only memorize concepts but rather learning activities by constructing and understanding independent concepts, so that learning outcomes last long in student memory.
