ABSTRACT
Due to the COVID-19 pandemic, the teaching of Biopharmaceutical Engineering course was carried out online and completed with satisfactory outcomes. In order to improve the efficiency of online teaching, ensure the substantive equivalence between online and offline teaching and achieve effective teaching, this article summarized the exploration and practical experience of online teaching, taking the Biopharmaceutical Engineering course as an example. This includes analysis of learner characteristics, selection of online teaching platform, development of teaching resources, optimization of teaching contents, BOPPPS teaching method-based design of teaching structure, and reflection of effective teaching. This paper is expected to provide a useful reference for online teaching.
