This presentation will demonstrate how students like a win-win teaching approach in a foundation finance course. Automating the traditional case teaching method in an online course (which can also be applied to face-to-face classes) not only increases students’ confidence and enjoyment of their learning but also reduces instructors' consultation and grading workload. In Finance, it is unavoidable that assignments, including but not limited to case studies, involve a lot of calculations, the amount and complexity of which depend on the level of the courses. Students will easily lose interest in working on a large assignment (such as a case study in this presentation) if they are unsure whether their calculations are correct or not throughout their work. Providing the opportunities to check instantly their calculation work bit by bit (intermediate answers in the calculation steps and final answer) without the fear of making many mistakes before proceeding further in the assignment will help engage students to work on the assignment and, in turn, in the course. This approach can be applied to courses in accounting, statistics, marketing research, and any course in which assignments call for/allow specific formats or highly standard structures. The approach has been presented at multiple conferences, while some more findings were presented at the 2023 IU East Faculty Scholarship Celebration on November 1, 2023.
