Problems and countermeasures of online teaching in the post-epidemic era

The outbreak of the COVID-19 epidemic has accelerated the transition of offline teaching to online teaching at colleges and universities in China which are speeding up the construction of information and intelligent education. Offline teaching is conducive to constructing a new type of education and talent training paradigm in the intelligent era. Through literature review and investigations, it is found that in the post-epidemic era, online teaching still has some problems, such as insufficient information technology guarantee, insufficient interaction between teachers and students, single teaching effect evaluation indicators and students’ poor self-discipline. To cope with the above-mentioned challenges, this paper has proposed the following suggestions for online teaching in the post-epidemic era: increase investment in information infrastructure, improve teachers’ information literacy and online teaching ability in an all-round way, update and improve the academic evaluation system and enhance students’ independent learning ability. All those suggestions aim to promote online teaching and create a new model of college education.
