Abstract:Heat transfer is a course with characteristics of numerous contents especially rich theoretical analysis, independent knowledge and many related courses. The problems such as boring mathematical analysis, non-expanded theoretical knowledge, single teaching form and disjointed theoretical and practical teaching appeared one after another during the whole teaching process. Aiming at the above problems, the following aspects related with teaching contents were improved, including merging research problems into teaching, strengthening theoretical background, selecting outstanding textbook and reforming test mode. In addition, teaching methods, including strengthening process assessment and practical capability, carrying out problem oriented teaching and WeChat classroom, were employed. The results showed that students' learning interest was improved, and the knowledge of heat transfer was more firmly mastered.
