Multi-Collaborative C + + Language Experimental Teaching Reformation Based on PTA

The experimental teaching of C + + language course is very important to consolidate the theoretical knowledge of classroom teaching, cultivate students' practical ability, innovation ability and independent ability to solve problems. However, the current experimental teaching of C + + language course still has the following problems: 1 The teaching methods and teaching resources are limited; 2 Students are passive to accept the knowledge; 3 The interaction between teachers and students are limited in the professional teaching process. So the reformation of C + + language programming teaching is imminent. We analyse the characteristics of C + + programming practice course and puts forward a multi-collaborative C + + language programming reformation based on PTA[1], which is an assistant teaching platform for experiment. The reformation proposed in this paper can integrate the multiple advantages of offline teaching, network platform and entity laboratory, which can also take measures to deal with the experimental teaching itself, build a "feature-oriented" practice problem set, improve students' learning efficiency and optimize the teaching effect of C + + programming practice course.
