任何一个教学目标的落实,都缺少不了反馈与娇正的紧密结合,因为这是构成目标教学不可缺少的关键性环节.这要求教师通过知识检测,及时获取学生的反馈信息,时刻把握教与学中存在的缺陷、错误及薄弱环节,有针对性的采取补救措施,弥补课堂教学中的缺陷与不足,以提高教学效果和学生掌握知识的能力,因此,学生题误后的跟踪训练十分重要. The implementation of any teaching goal can not be combined with the close combination of feedback and prudence, because it is an indispensable link in the formation of the target teaching. This requires the teacher to acquire the feedback information of the student in a timely manner through knowledge detection and grasp the teaching and learning at all times. There are flaws, errors and weak links in the process, and targeted remedial measures are taken to make up for deficiencies and deficiencies in classroom teaching so as to improve teaching effectiveness and students’ ability to master knowledge. Therefore, it is very important for students to follow up after mistakes.
