Pair Programming for Enhancing Communication in the Fundamental C Language Exercise

C language is a required course in information science. Students not only need to develop a strong interest in the subject, but also lay a good foundation for C language in studies. The discipline plays a very important role in professional courses, and therefore we need to provide a pleasant environment in which students can complete the fundamental C exercise. Pair programming reduces the pressure of solving a task because in pair programming two programmers tackle the challenge not just one programmer. Moreover, pair programming makes it easy to start a discussion of the subject even if two programmers have different levels because this is the fundamental C exercise. In this study, we design an experiment featuring the pair programming technique to enhance communication in the fundamental C exercise. The experimental results show that pair programming is an effective tool for enhancing communication in the fundamental C exercise.
