当前,高中数学课程标准修订组进一步强调培养学生的数学核心素养,提出:用数学的眼光观察世界,用数学的思维分析世界,用数学的语言表达世界。那么如何在数学课堂教学中,培养学生的数学素养呢?笔者认为,数学课堂需突出数学本质,教师应引导学生主动参与知识的建构过程,将发现问题、解决问题的思想方法和思想观念教给学生。“直线的参数方程”一课就是围绕“尊重教学规律、关注学生的发展”这一理念进行教学设计的。
At present, the revision group of high school mathematics curriculum standards further emphasizes the cultivation of students’ core knowledge of mathematics. It proposes: to observe the world from the perspective of mathematics, to analyze the world with mathematical thinking and to express the world in mathematical language. So how to cultivate students’ mathematical accomplishment in mathematics classroom teaching? The author believes that mathematics classroom should highlight the nature of mathematics, teachers should guide students to take the initiative to participate in the process of knowledge construction, to find problems, to solve the problem of thinking methods and ideas to teach student. “A straight line of parametric equation ” lesson is around the “respect for teaching law, concerned about the development of students, ” the concept of instructional design.
