Mask Manufacturing Approach Using Case-Based Learning

This research was conducted to (1) investigate the activities and cost drivers in the mask manufacturing process, (2) investigate the effectiveness of activity-based costing lessons, and (3) perform a comparison of learning achievements attained through the case-based learning of mask production using the activity-based cost method. The study results were reported as means, standard deviations, and dependent samples (t-test) results. The analyses revealed that five activity centers are involved in the production of valveless surgical masks and costs were determined by both volume and duration, whereby the Process Efficiency/Product Efficiency (E1/E2) ratio of 82.25/81.55 met the predetermined standards. Moreover, students' academic achievement after completing the case-based learning activity increased at a significance level of 0.01. Thus, these research findings can be of value for teachers aiming to develop lessons for students in accordance with the 21st century teaching and learning strategies.
