The main purpose of activating teaching has nothing to do with any change of the teacher's teaching. It neither tries to overturn his/her original teaching designs. On the contrary, it pursues the goal of achieving a teaching through the adjustment of the teacher’s mental life as well as the revision of his/her teaching concepts to target the active teaching. This paper tries to explore the strategies and practices of active teaching from several perspectives, including subject teaching, subject knowledge, the process of activating the teacher's teaching activities. Some suggestions offered are the meaning and practice of activating teaching, the teaching courses, and related subject knowledge. Taking them and going further with higher volume of teaching practice, as well as putting forward with appropriate strategies, would likely help a teacher better keep in breath with possible changes of teaching activation in the future.
