Interactive teaching has advantages and is worth adopting, but not every class is suitable for interactive teaching. Interactive teaching requires teachers to carefully prepare questions and design possible situations. However, the teacher's design may be different from the actual situation, and students may not be able to explore according to the teacher's requirements, resulting in the phenomenon of ineffective exploration. In the interactive classroom, students' enthusiasm is very high, but there will also be problems that students don't read carefully and have poor thinking ability. Students' study may be very different. Students at different levels have different understanding of the problem, and what they get in the inquiry will be very different. Some students may not really understand the problems in their studies. Interactive teaching, because it involves a lot of inquiry questions, requires students to spend a lot of time exploring, so it is impossible for teachers to dig deep into the content of teaching materials. There are also differences in students' understanding ability and thinking angle of teaching materials. Simply let students think, the teacher explains too little, the teaching content may not be understood thoroughly, and the learning is not deep enough, which is not conducive to mastering the teaching content completely and accurately, and the depth of learning may be problematic.
