The effects of passive and active learning classes are investigated in a basic mathematics training for electrical engineering. The characteristics are considered from the viewpoint of the teacher. The level of understanding of all of the students and the degree of difficulty of the problems of coursework can be checked in real time. However, some contrivance is needed to move the students, such as use of the blackboard by students. Also, the setting of coursework problems is important for the active learning style.
