In view of the isolation of the software and hardware teaching environment, isolation of various online teaching platforms and lack of coordination of data, it is not conducive for further promotion of ‘Internet Plus Teaching’ and the improvement of online teaching. The Trinity teaching platform, namely ‘Learning in Zhejiang University City College’ is built against the background of digitalisation reform in colleges and universities. The teaching platform integrates the smart classroom, the Zhiyun Classroom (online classroom) and the curriculum platform. The platform breaks through the limitation of time and space, connects the teaching process and implements the integrated ‘teaching, learning, evaluation and management’ based on data collaboration. It is fully applied in Zhejiang University City College, and is stable, efficient and convenient, with a high access rate and better interaction between teachers and students. It effectively implements closed-loop management of the teaching process, changes the educational form of teacher education, student learning and school management. It also adapts to the cultivation of innovative and individualised talents under the new situation, and further deepens reforms of ‘Internet Plus Teaching’. It provides a solid support for the whole process management of student learning.
