随着新课程的实施与深化,数学学科从内容到形式都发生了明显的变化,在课堂中创设丰富的情境教学,引导学生自主探究、合作交流等教学形式已经被广大教师所运用。但我们也发现一些教学走入了一个怪圈:盲目地追求教学的形式和活动的多样化而忽视了教学的本真,教师教得很辛苦,学生的学习效果却不理想。这就引起我们大家的反思,从而更多地来关注课堂教学的有效性。 With the implementation and deepening of the new curriculum, mathematics has undergone obvious changes from the content to the form. The creation of rich situational teaching in the classroom to guide students to explore, collaborate and exchange their teaching forms has been used by a large number of teachers. However, we also found that some teaching went into a vicious circle: blindly pursuing the diversification of teaching forms and activities while neglecting the true nature of teaching, the teachers taught very hard and the students did not learn well. This arouses the reflection of all of us so as to pay more attention to the effectiveness of classroom teaching.
