What is High School Math Fragment Teaching 5

On the basis of the lecture, a fragment of a chapter in the course is taken to explain or teach, and the time is about 10 minutes.

To put it in layman's terms, you have 4 contents in 40 minutes of a class, and the fragment teaching is to go to one of them, which is a 10-minute teaching clip.

Definition of fragment teaching.

Intercept a certain part of the teaching content of a certain lesson and let the teacher teach, and the time is roughly limited to about ten minutes. That is to say, fragment teaching is only a section in the process of teaching implementation, and teachers can show their teaching ideas, teaching ability and basic teaching skills by completing the assigned teaching tasks.

Fragment teaching is different from classroom teaching, the former is local, virtual, the function is teaching and research or evaluation, and the participants are leaders, peers, experts, and judges; The latter is holistic and practical, and its function is to "preach and receive karma and solve doubts", and the listeners are students.

Fragment teaching is different from teaching fragments, the former is taught according to the specified "fragment", and the instructional design and implementation process are independent; The latter is just a part of the record taken from the complete classroom teaching process after class.

Fragment teaching is different from "lecturing" in that the former is a simulated classroom teaching, while the latter just talks about classroom teaching.
