What do you guys think is the best method to teach juniors web dev? What are some things that would make you love a uni class and learn it?

I am teaching web dev and I find it very hard to engage all the students as almost half of them are not interested and I think they see the class too difficult(web basics?!). This is my first class teaching and I want to gather some feedback here and implement it in my class.

So, basically let me know of anything that makes you love and hate abclass because of the teacher's methodology. Thanks a lot
