Abstract: Following the educational philosophy of outcome -oriented approach and sustainable development, this paper puts forward and practices an applied course group teaching system to cultivate students' professional behavior and ability, which integrates teaching, learning and practicing. For the teaching, the coverage or close connection of knowledge points among different professional courses in software development direction result in repeated teaching and isolation of course content in the course teaching process. To deal with this problem, this paper proposes project-oriented applied course group collaborative teaching mode. The framework of software development course group is first introduced; then this paper expounds this cooperative teaching mode in three aspects: designing comprehensive teaching cases, collaborative teaching method for the same ability stage and smooth course transfer among different ability stages. For the learning and practicing, this paper proposes taking curriculum design as the starting point to form cooperative practice platform for solving the problems of limited class hours, outdated teaching content and simplistic teaching mode and gives detailed explanations from content design in curriculum design, implementation route, multi-level and multi-dimensional assessment mechanism. For the comprehensive ability training, considering that it is difficult to improve students' ability of "solving complex engineering problems" resulting from the discontinuity of ability cultivation caused by isolated teaching, this paper discusses how to construct a comprehensive training system oriented around professional behavior and ability in line with the software development cycle.
