Research on the Construction of Regional “Cloud-Network-Client” Integrated Teacher Development Platform

Teacher professional development is the fundamental guarantee for promoting teaching reform, and there are two means to promote teachers' professional development: “internal promotion” and “external promotion”. At present, the teacher development platform at home and abroad is in a stage of vigorous development. This paper deeply analyzes seven representative domestic and foreign teacher development platforms, and finds that the existing platforms have problems such as system data dispersion, separation of system development and teacher development, and weak ease of use of the platform. Based on this, a teacher development platform with cloud-network integration is proposed, the connection between the cloud data layer, the system application layer and the teacher terminal layer is analyzed, and the design concept of the platform is proposed.
