The teaching context in the video is different from the one I've been working in in the following ways:
1 The lecturer is working with his peers, I'm working with my students
2 The live session is a lecture-type session, with input but no interaction. This is very different from my context, where I call on my students to interact with me throughout the class
3 I make a lot more use of emojis and images in my lesson to clarify my instructions , engage my students and keep my students' attention
Similarities include:
1 The use of voice notes - this is so useful . I don't think I could make WhatsApp classes work for me without voice notes
2 The use of images and screenshots - I find these incredibly useful too
