Rectify the new teaching time and space project and stop the project operation. "Teaching New Time and Space" is a multi-functional teaching and education software jointly launched by the teaching research office of primary and secondary schools in Jiangsu Province and the Basic Education Department of the Education Department of Jiangsu Province. It integrates three systems: resource sharing, lesson preparation integration and teaching evaluation. At the same time, it has five functions: instant communication of language and video, free sharing of high-quality resources, online interaction of teaching and research, remote menu self-study, and dynamic and timely push of information. The reason why the new teaching time and space was removed is that Jiangsu Telecom Industry Group Co., Ltd. and Jiangsu Audio-visual Education Center (Jiangsu Education TV Station) stopped the operation of the new teaching time and space project because of rectification.
