We suggest trying regular video calls so your students can feel connected
Live communication is very important. Students see their teacher and each other, and can better perceive the material for classes. In addition, the opportunity to see each other on video serves as good support and motivation for learning.
Services can work on a PC, smartphones, and tablets, which allows students to participate in a lesson from any available devices.
Possible tools: Skype, Zoom, GoogleHangouts
