在新课程改革和开展高效课堂活动的双重背景下,教师要重视通过问题启发学生积极的思维活动,以问题为主线来组织和调控课堂教学,通过问题启动探究、深化探究、反思探究。把问题的解决与新知识的学习紧密结合起来,把问题的解决与归纳数学知识紧密联系起来,把问题的解决作为实现高效课堂的有效途径。 Under the dual background of new curriculum reform and efficient classroom activities, teachers should attach importance to inspiring students’ active thinking through questions, organizing and regulating classroom teaching with questions as the main line, initiating and exploring, deepening and introspecting through questions. The problem solving and new knowledge learning are closely integrated, the problem solving and induction of mathematical knowledge are closely linked to the problem solving as an effective way to achieve efficient classroom.
