SUMMARY
The purpose of this study is to evaluate whether learning media with a computer-based branching program can improve learning outcome on Digital System Design course or not. IDI (Instruksional Development Institute) Reseacrh and Development (R&D) has been applied to develop program and to evaluate the effectiveness of learning media with a computer-based program branching on Digital System Design course. There are three stages in this research, defining, developing, and evaluating. Content validity of learning media with a computer-based program branching was found highly valid. Based on the learning outcomes, the effectiveness of learning media was found effective. More over,based on the teachers and the students response, itwas found that the learning media was found very highly practical. Based on the data analysis, it was found that learning media with a computer-based branchingprogram can improve the students' learning outcome on Digital System Design course.
