Difficulties and challenges in online teaching and learning
Abstract: Teaching and learning in general and at higher education in particular are constantly changing in the recent period. With the influence of the Covid-19 pandemic worldwide, online teaching and learning has now become the mainstream method in Vietnam and other countries. It is widely believed that online teaching should be considered as the main method that can completely or partially replace face-to-face teaching. However, online teaching involves many dilemmas that make it difficult to widely apply and replace the traditional teaching method. This article aims to clarify some of the problems encountered in online teaching and learning.
Abstract: Since its birth in the second half of the 20th century, the Internet has been developing strongly in recent decades, providing a variety of services to meet the diverse needs of individuals, families, organizations, and countries. With the increasing use of the Internet and related services, people are empowered with more rights, especially freedom of expression, to overcome geographical distances and promote the spread of information. However, the disproportionate development, the inadequacy in regulations and unequal order in cyberspace are increasingly evident, creating a widening gap among countries and regions. In addition, a great number of activities in cyberspace have left serious consequences on society, posing a dilemma of cybersecurity for countries and the international community.
