试卷讲评是数学教学中的一个重要环节。可以及时揭示教与学双方存在的问题,促进教师改进教法,学生改进学法,使教与学得到优化。讲评时我们应坚持做到:课前师生共诊断、课中师生共参与、课后师生共反思。 Examination paper evaluation is an important part of mathematics teaching. It can promptly reveal the problems existing in both teaching and learning, promote teachers to improve teaching methods, improve students’ learning methods, and optimize teaching and learning. When commenting, we should insist on: pre-teacher and student total diagnosis, teacher-student participation in class, after-school teacher-student reflection.
