This paper proposes a new presentation system integrating a Microsoft PowerPoint presentation in a two-layer method, called the TL system, to promote learning in a physical classroom. With the TL system, teachers can readily control hints or annotations as a way of making them visible or invisible to students so as to reduce information load. In addition, the system can synchronize a teacher's lecturing actions for a PowerPoint presentation with his/her voice and also create web-based multimedia materials. By reviewing these multimedia materials, students can recall the problem-solving skills the teacher taught them in class. In this study, an exploratory test was carried out with 12 teachers and 91 students in a college of technology. Research data were collected through the instructional technology use questionnaire (ITUQ) for teachers as well as through the course attitudes scale (CAS) and the mathematics achievement test (MAT) for students. The results revealed that the TL system helps teachers to have a smooth teaching process of presenting teaching materials. The students in the experimental group had a better course attitude and achieved higher MAT scores than did those in the conventional group. (Contains 8 figures and 4 tables.)
