I usually use PowerPoint presentation and books to teach also videos for make the class more d every class have his quiz.
Every class it is 60 minutes including the word scripts for the class that we used in the teaching and there's alot of quiz at the lesson period.
After we finish the class there is home work every single class that the student have to make and send it back before the next class,to be sure that the student have understand everything that we take it at the class.
