Since the reform and opening up, Sino?foreign cooperation in running schools has become an important part of China's education system. International curriculum is the carrier and the specific form of cooperative running schools. The quality of curriculum teaching directly affects the quality of talent training, which is the top priority in Sino?foreign cooperative running schools. Online course teaching is one of the important teaching methods for Chinese?foreign cooperative schools. Due to the differences between Chinese and foreign teaching modes, there are some problems to be solved for course teaching in video teaching, language communication, teacher team, ideological and political courses, and assessment methods. For this purpose, taking the course "Power System Foundation" as an example, it puts forward the specific countermeasures of teaching team construction, teaching resource optimization, curriculum structure optimization, teaching mode innovation, curriculum integration of ideology and politics, and the application of modern science and technology. The implementation of these countermeasures is conducive to the improvement of course teaching quality and achievement of good teaching performance. Through teaching reformation, 74% of the students in the international class of Electrical Engineering in Grade 2019 have achieved excellent results in the comprehensive evaluation mechanism, which proves that the students have a good grasp of the course "Power System Foundation", and the course teaching reform has achieved preliminary progress.
