Improving Understanding of Wiggins Concept through the Application of Blended Discovery Learning Model in Biology Learning

Students are required to have the ability to think, one of which is understanding. In the era of the fast development of information technology, understanding in students is not just knowing facts, but knowing the meaning, and emphasizing the involvement of students in dealing with problems. This research aimed to determine the improvement of students' concept understanding based on Wiggins' aspects of understanding, which are explain, interpretation, application, perspective, empathy and self-knowledge in biology learning by applying a blended discovery learning model. This research is a quasi-experimental research with pretest-posttest control group design. The population in this research were all students of class X Mathematics and Natural Sciences SMAN 1 Sumber in the 2022/2023 academic year with samples of class X Mathematics and Natural Sciences 4 as the experimental class and X Mathematics and Natural Sciences 3 as the control class. Data collection techniques used tests, and questionnaires. The results showed that there were differences in the improvement of students' understanding based on significant aspects of Wiggins' understanding in biology learning using models of blended discovery learning on kingdom plantae material.
