新课程理念倡导教师在课堂上引导学生积极参与各种探究性学习活动,从而调动学生学习数学的兴趣,培养学生发现问题、提出问题的能力,促进学生的思维在更广阔的空间得到发展.所以教师自主研发设计探究性活动在中学数学教学中的重要性日益显得突出. The new curriculum concept advocates teachers in the classroom to guide students to actively participate in a variety of inquiry learning activities, thereby mobilizing students interest in learning mathematics, students develop the ability to identify problems, ask questions and promote students’ thinking in a broader space to be developed. The importance of teachers’ independent research and design inquiring activities in middle school mathematics teaching has become increasingly prominent.
