The Online Teaching Practice of the Tunnel Engineering During the COVID-19 Pandemic

: To cope with the constraint of the COVID-19 pandemic, online teaching is widely used in education. However, the adaptation from conventional face-to-face dominated classroom teaching to that of online mode is generally in a swift way. Considering the significant features of the online learning and teaching situation, both instructors and students would be confront with various challenges. Here is the presentation of the online teaching practice of the Tunnel Engineering during the COVID-19 pandemic. The practice indicates that the major challenges of the instructors are to perform the multiple roles of content expertise and presenter, student work assessor, online teaching procedure facilitator and manager. The students are confronted with the requirements of competence in terms of learner, presenter and respondent. The course design and implementation plan are initially tuned at the beginning of the online teaching to adapt to the new situation. With a new teaching strategy being set up, the online teaching activities have been progressively tailored in corresponding to the feedback from students, peer reviews, the results of formative and summative assessments on the learning and teaching activities. The experience and lesson learned from the Tunnel Engineering online teaching for six classes from the three academic years 2020 to 2022 are presented in terms of course design and implementation plan, assessments, effective interaction and online teaching community.
