Abstract: Aiming at the problems of some professional courses in engineering,such as strong theory and abstract concept,heavy theory and light practice in teaching process,disconnection between teaching content and practice,etc.Combined with “Internet +” and the characteristics of college students,it was put forward to cultivate the innovation ability of design in engineering specialty experiment on the computer as the core,in order to improve the teaching quality and students’ innovation ability objective in this paper.Taking hydrology statistics course as an example,combined with the hot topics and difficult problems of the discipline development,the mode,content and assessment method of the comprehensive experiment on the computer are designed.The teaching practice shows that the setting up of the comprehensive experiment on the machine improves the students enthusiasm for learning,makes the distribution of the results more reasonable,and raises and improves the students creative ability.
