In the classroom, his classes are often packed, and his elective courses are "harder to grab than the concert tickets of JJ Lin". On the social network platform, he often uploads online classes voluntarily, and more and more students watch his math classes. Some people even "expect him to update the video like an American TV series."

Now, the online mathematics courses uploaded by Teacher Song include four courses: linear algebra, calculus, advanced mathematics, probability theory and mathematical statistics. Song Hao analyzed the reasons why students are willing to watch. First, math classes are difficult. Second, three of them will last for two years, which requires students to study repeatedly.

"Mathematics itself is very difficult, and the consistency is particularly strong. If you can't learn the first chapter, you may not understand the rest. In addition, mathematics also needs to be understood in order to truly master and improve scores. " Song Hao said that from the student's point of view, what he needs to do is to make a knowledge point more detailed. "For example, how did you get this number? Is it a plus sign or a minus sign? How did you get this property? Slowly, students can understand and master something by themselves. "

Song Hao is loved by students, on the one hand, because his online mathematics course is very clear and the teaching method is lively and relaxed; On the other hand, he respects students' feelings very much and often adjusts the way and method of lectures from students' feedback; Thirdly, he often encourages students to study hard, and strive to achieve transformation in the four years of college, so that their lives can reach a new level.
