Abstract Through the comparative analysis of the characteristics of time and frequency of teachers' use of instruction behavior chain(IBC) and instruction behavior pair(IBP) in the normal classroom of “acid and alkali” units of novice teachers and experienced teachers, it is found that as for the IBC, novice and experienced teachers both spent more time on a higher level of IBC. The frequency of high-level IBC of experienced teachers is better than the novice teachers, and the rational time in different IBC is more reasonable. As for the IBP, novice and experienced teachers mostly both use the type of “asking” and “lecturing”, and students often use the way of “answering” to start classroom activities. The time of the experienced teachers using the way of “moving” and “thinking” is obviously higher than that of the novice teacher. As for the level of the students participating in the class, experienced teacher is better than that of the novice teacher. This study highlights novice teachers should organize and arrange their classroom teaching behaviors effectively, pay great attention on the mastery of “acid and base” content knowledge and pedagogical content knowledge. Moreover, both experienced and novice teachers should provide opportunities for students to engage in their classrooms.
