In the context of online learning, the teacher's role would be to create a conducive environment for learning that promotes social interaction, modeling, and observation. The teacher should provide opportunities for learners to observe and interact with others, create activities that promote reflection, and provide feedback on performance (Glanz et al., 2010).

According to Bandura's Social Learning Theory, teachers play an important role in facilitating the learning process by providing a model for appropriate behavior and providing feedback on the learners' performance. In the context of teaching "ethics in substance abuse," teachers can use a range of instructional strategies to model ethical behavior and decision-making. For example, teachers can use case studies or scenarios to help learners explore ethical dilemmas and identify possible solutions. In addition, teachers can use role-playing or other experiential learning techniques to allow learners to practice making ethical decisions in a safe and supportive environment (Glanz & Bishop, 2010).
