Online learning has many challenges, and student engagement is one of them. I would like to do my PhD in computer science and my topic is about student engagement online
When I am teaching face to face I can look at students face to face I can decide whether students are following me or not . The question is  if I teach using zoom how I do that . How I really know the students are engaged and if they are not engaged And how we can provide a help to students to be engaged.

So I will investigate the use of a few different  artificial intelligence approaches ,……  , deep learning and deep forest and I will compare between them and choose on of them
