Abstract
Problem solving skills play an important role in facing challenges and opportunities in the industrial era 4.0. However, these skills have not been trained properly in school. Therefore, the purpose of this study was to describe the feasibility of business and energy teaching materials with a direct teaching model to improve students' problem solving skills. This research uses ADDIE. Implementation test on 25 students of class X MIPA at a high school in Banjarmasin, Indonesia. Collecting data using observation sheets of learning implementation and problem solving tests. The results showed that the direct teaching phases could be implemented well and the students' responses were in good category. In addition, the problem solving n-gain is 0.62 in the medium category. Thus, the business and energy teaching materials developed are feasible to improve students' problem solving skills in learning physics.
