练习是课堂教学重要一环,也是教师进行教学反馈的手段,直接影响高效课堂的构建。因此,教师要重视练习题目的设计,注意练习形式的多样性、层次性,内容的梯度性,让学生将课堂所学知识用于解答问题,形成活学活用、举一反三的能力。 Practice is an important part of classroom teaching, but also a means of teachers’ teaching feedback, which directly affects the construction of efficient classroom. Therefore, teachers should pay attention to the design of exercises, pay attention to the diversity of forms of practice, and the gradient of content so that students can use the knowledge they have learned in the classroom to answer questions and form their abilities to learn and use well.
