《义务教育数学课程标准》提出:要“使学生在掌握基础知识的同时,智力得到发展,能力得到提高。”“要遵循学生的认知规律,重视学生获取知识的思维过程。”这就为我们改革教学、提高学生素质指明了方向,要使学生既长知识,又长智慧,就必须把打好知识基础和培养学生智能两者统一在教学过程中,要重视学生思维能力的训练,不但要重视学生得出结论,更要重视学生获得结论的思维过程。对于结论,教师历来是重视的,因为它反映着学生的认识是否正确。但是,学生得出正确结论的思路并不是完全相同的,这反映 “Compulsory education mathematics curriculum standards” put forward: to “enable students to master basic knowledge at the same time, intellectual development, ability to improve. ” “Students should follow the law of cognition, emphasis on students to acquire knowledge of the thinking process. ”This points out the direction for us to reform teaching and improve the quality of students. To make students both long-term and long-term wisdom, we must lay a solid foundation for knowledge and develop students ’intelligence in the process of teaching.
