Language points are explained to students one by one in traditional teaching, and their varieties make the first learning of a computer language rather difficult. All the language points in computer language courses are successive and interdependent, so any defect or misunderstanding would bring barriers to the subsequent learning. Based on the natural way of language acquisition of human beings and iterative models in software engineering, an iterative approach is put forward in this paper in order to maintain the consecutiveness of the language points and help students in their software research and development.
