在减负的大环境下,怎样做好课堂有效的练习是巩固一堂课所学知识的关键。有效的课堂练习可加深学生的印象,对所学的东西有所利用,练习新旧知识的交融。同时也能让教师了解到学生对学习的内容的掌握情况,及时对课堂的欠缺处补足,为高质量的课堂教学巩固效果。 Under the environment of reducing the burden, how to effectively practice in the classroom is the key to consolidate the knowledge learned in a class. Effective classroom practice can deepen students’ perceptions, make use of what they have learned, and practice the blending of old and new knowledge. At the same time, it also enables teachers to understand the mastery of the students’ learning content and promptly make up for the deficiencies in the classroom so as to consolidate the effect of high-quality classroom teaching.
