In the epidemic period, online teaching has become the most important teaching form. On the basis of questions-centred massive open online courses (MOOCs) teaching, the online teaching mode of college physics was studied and discussed using the Tencent classroom, WeChat/QQ and Wisdom Tree Platform. MOOCs before class, Tencent classroom during class, WeChat/QQ in the whole process including solving problems after class, and Wisdom Tree Platform for quality inspection of online teaching were practiced in the teaching of each chapter including mass point kinematics. Due to the problem-oriented implementation of the three stages, the results of the online mock test were better than expected. In other words, the online teaching supported by various online tools could effectively guarantee the quality of teaching.
