Teaching biochemistry well is not an easy job for teachers and so is learning biochemistry well for students. Just as many students often complain, they virtually always fail in either physiology or biochemistry. I have been teaching biochemistry at Nanjing University for over 25 years and am very successful in my biochemistry-teaching career. The way and style that I teach biochemistry is highly praised by both my students and my fellow teachers. As an instructor, the most important thing is, I think, you have to do your best to arouse or ignite students' interest in biochemistry learning. But how? In this article, I will introduce many first-hand practical tips on how to arouse the students 'interest in studying biochemistry from giving the first lecture to last lecture, from how to combine advanced teaching methods with traditional teaching methods to how to combine classic biochemistry with latest biochemical developments, from the main classroom teaching to organization of extracurricular activities as the second classroom, and so on. These tips are proven very useful and then can be followed by other professors who are teaching biochemistry. Hopefully, they can help many professors improve their skills for teaching biochemistry.
