Chinese is a complicated subject, but I will start with the simplest Pinyin and work my way up. The class will adopt the ppt mode, as long as students have any questions we can discuss at any time, to ensure that we can learn the most knowledge efficiently in a short time. I used to teach elementary school students, a class of forty, and they all finished their course well. I have also taught foreigners that as long as you need some patience, you can progress quickly, you just need to believe in the teacher and believe in yourself!
