Calculous is one of the required courses for non-arts students in vocational and technical institutes. Many students have difficulties in learning Calculous because of the characteristic of the course and basic knowledge level of students, so that the situation of teaching Calculous is not optimistical in vocational and technical institutes. Hence, it is necessary to properly reform the teaching of Calculous in those institutes.
