Online learning has not been unfamiliar to students and teachers since 2020. Technology improvement is one of the ways that online learning can run effectively. However, the reality found in Christian School in Bangka is the lack of student activity in answering, asking, activating camera features, and even doing exercises/tasks. From this problem, the purpose of writing this journal is to know the application of reinforcement to improve students’ activity during online learning. Reinforcement is one of the Operant Conditioning learning theories that prioritizes stimulants such as motivation, reward, and punishment for getting the desired response. This theory is very contrary to the Bible, as it assumes that humans can be conditioned like animals, whereas from the biblical view, humans are made in the image of God. Through this journal, the author tries to explain how reinforcement theory is viewed from a biblical worldview and how it is applied in Christian education. The research was conducted using a qualitative descriptive method supported by observational evidence at a Christian school in Bangka. The results obtained show that the implementation of reinforcement can improve student learning activities during courageous learning and make students aware of their identity as Christ’s disciples in the classroom.
