Abstract

The Praktisi Mengajar program is thought to have an important role in improving the quality of student learning in tertiary institutions. Universities invite practitioners as guest lecturers for certain courses with the hope of providing practical experience to students so they are better prepared to face the world of work after graduation. However, there are still many unanswered questions regarding the effectiveness of Praktisi Mengajar in improving course outcomes. The purpose of this study is to investigate how the Praktisi Mengajar program effects course outcomes and to describe student perceptions of the program. The study's findings indicate that the Praktisi Mengajar Program has an impact on KPMI course outcomes, and a description of students' positive perceptions toward the program was collected.
