近几年,在教材教法及教研活动中,广泛开展“三课”(即说课、做课和评课)活动,促进了教师相互对教材、教法的研究、经验交流.通过这项活动使新教师能较快的成为教学骨干,也促使加快老教师对旧知识更新和旧教法的改革,对全面提高教学质量和素质教育的实施起到双重作用. In recent years, the “Three Lessons” (ie lectures, classes, and assessments) activities have been widely carried out in teaching materials and teaching and research activities, which have promoted teachers’ mutual study of teaching materials and teaching methods and experience exchanges. This activity has enabled new teachers to become the backbone of teaching faster, and has also contributed to accelerating the reform of older teachers’ old knowledge and old teaching methods, and has played a dual role in the overall improvement of teaching quality and the implementation of quality education.
