since the outbreak of COVID-19 some international students who traveled to their home countries can no longer return to their host countries for example China. As a tentative solution, online teaching and learning have been used as a substitute to bridge the disrupted gap in education. at this time, many international students complain that online learning is not very effective and most teachers on the other hand complained that it is very difficult to effectively engage students in an online class. somen international students are already demotivated to even continue their studies abroad, especially those whose's research projects demanded that, they use a laboratory (pure sincere) in their host university abroad, yet online studies can not solve this problem.
while most host countries like China, UK, and American still have strict regulations on the return of international students, most international students who are in this "Limbo" are gradually losing interest in further studies abroad if this situation persists for some time.
what is your take on this?
