In the age of artificial intelligence, the mainstream educational form is characterized by the large-scale personalized education that provides learners with precise and personalized learning services by means of modern information technology according to the characteristics of learners. Teachers' defects in general knowledge, cognitive ability, emotional management and physiological quality are increasingly exposed. According to Stigler's theory of "human nature structure", AI teaching assistant system based on artificial intelligence will be a "key technology" in future classroom teaching to effectively make up for teachers' defects and stimulate teachers' potential. On the basis of in-depth investigation of teaching activities in the age of artificial intelligence, the function of the existing AI teaching assistant system and the current situation of human-machine collaborative teaching, this paper holds that the AI teaching assistant system is better at cognition, but the emotional and creative intelligence of teachers are irreplaceable. Then, this paper proposes a future classroom teaching behavior analysis framework and a AI teaching assistant system model, which include four different functional relations of "AI substitution", "AI assistance", "AI enhancement" and "AI empowerment". Finally, the future challenges of AI teaching assistant system research are prospected so as to provide theoretical references and ideas for the study of AI teaching assistant system in the intelligent era.
