As the foundation course and core course of civil engineering-related specialties civil engineering construction course teaching is through online platforms in order to achieve the requirement of no suspension of classes during the period of epidemic prevention and control. Because the course of civil engineering construction has the characteristics of large amount of information, strong comprehensiveness and weak correlation between chapters, it is very important to explore an online teaching method that can not only enable students to adapt quickly but also ensure the quality of teaching. This online teaching is based on the civil engineering construction course of a university in South China. It is based on China University MOOC, Architectural Cloud Class, Tencent Class, QQ group and other online platforms. The questionnaire survey is used to evaluation of the effectiveness of online teaching. The results show that teaching based on multiple online platforms provides students with a rich and flexible way of learning, which can significantly improve students’ autonomous learning ability, expand their knowledge, and improve learning effects.
