E-learning is currently quite common. The use of local area networks (LANs) is also common when teaching over the Internet. E-learning to support conventional lectures using a blackboard is a common Internet occurrence these days. When a lecture is recorded with the teacher's voice and stored on a server, students can go over the information as many times as they desire. We used "EduCanvas", a commercial application, as an e-learning system. The system is quite convenient for students. Students filled out a questionnaire after using the e-learning system. The effectiveness of this e-learning system was improved by the Internet review. These lecture files will be useful archives for all types of students.
