《义务教育数学课程标准》要求学生学有价值的知识,有实用性的知识,促使学生的发展,提高课堂教学的有效性。高效课堂就是老师教学理念必须高效;学生所获必须高效;教学投入产出必须高效。在我校,以“导学案”为载体,学生自主探究为主旨的高效课堂教学改革试验已经得到广泛的推进。教改后,我们的数学课堂发生了惊人的变化:课堂上老师讲得少了,学生讲得多了;学生的思维活了,问的问题多了,解决问题的方法多了,学生的视野开阔了。 “Compulsory education mathematics curriculum standards” require students to learn valuable knowledge, practical knowledge, to promote the development of students and improve the effectiveness of classroom teaching. Efficient classroom is the teacher teaching philosophy must be efficient; students must be efficient; teaching input and output must be efficient. In our school, guided by the “case” as the carrier, the independent research of students for the purpose of efficient classroom teaching reform experiments have been widely promoted. After the reform, our mathematics classroom has undergone astonishing changes: the teacher said less in the classroom, the students speak more; the student’s thinking is alive, they ask more questions, and there are many ways to solve the problem. The students have a broad vision It’s
