Abstract

For Computer Science and Technology students, the development of practical programming skills is crucial. In order to cultivate students’ practical programming skills, Online Judge (OJ) system has been developed rapidly and widely used by many universities. However, the OJ system-based teaching model has not been sufficiently analyzed in terms of teaching effectiveness. Therefore, in this paper, we analyze the problems in teaching programming courses, the current application status of OJ systems and teaching models in many universities. We propose a teaching model of programming courses based on OJ system in Beijing University of Chemical Technology (BUCT). Besides, we apply this model to the course teaching of Computer Science and Technology in BUCT for nearly 10 years and accumulate a large amount of raw data of programming practice activities. After scientific and reasonable data analysis, it is proved that the teaching model has achieved good teaching effect. The results of the experiment show that students’ use of the OJ system was positively correlated with their scores in the programming course. The more students practiced programming in the OJ system, the higher the students’ scores in their programming courses.
