随着中学教学改革的不断深入,我国中学教育教学改革取得了很大的发展,但在中学课堂中传统的教学模式占据统治地位,不能较好地体现新课标中突出学生主体地位的理念。数学教学活动中要注重培养学生主动获取知识的兴趣和能力,而学案导学则是实现学生主动学习、积极参与学习的一条行之有效的途径。同时,它还为学生与教师之间的合作交流创造空间,让学生积极参与到数学学习的全过程中来,让学生主动去获取知识,培养学生的自学能力和创新精神。 With the continuous deepening of middle school teaching reform, great progress has been made in the reform of middle school education and teaching in our country. However, the traditional teaching mode in middle school classrooms occupy a dominant position and can not well reflect the concept of highlighting the dominant position of students in the new curriculum standard. In mathematics teaching activities, we should pay attention to cultivating the students ’interest and ability of taking the initiative to acquire knowledge. However, guiding students in case studies is an effective way to realize students’ active learning and active participation in learning. At the same time, it also creates space for cooperation and exchange between students and teachers so that students can actively participate in the whole process of mathematics learning so that students can take the initiative to acquire knowledge and develop students’ self-learning ability and creativity.
