普通高中数学课程标准(实验稿)在教学建议中明确指出:“学生的数学学习活动不应只限于对概念、结论和技能的记忆、模仿和接受,独立思考、自主探索、动手实践、合作交流、阅读自学等都是学习数学的重要方式.”课标的这一要求对于那些只习惯讲授式教学的高中数学教师来讲是一种挑战,高中数学教学如何丰富学生的学习方式、改进学生的学习方法?脱以“椭圆及其标准方程”的教学为例,从创设问题情境;经历概念的形成;建立数学模型三个层面让学生经历知识的形成过程,同时丰富学生的学习方式.划 Ordinary high school mathematics curriculum standards (experimental draft) clearly pointed out in the teaching suggestion: “Students’ mathematics learning activities should not be confined to memory, imitation and acceptance of concepts, conclusions and skills, independent thinking, self-exploration, hands-on practice and cooperation Communication and reading self-study are all important ways to learn mathematics. ”“ This requirement of curriculum standard is a challenge for those high school mathematics teachers who are accustomed to teaching. How high school mathematics teaching can enrich students ’learning styles and improve students’ Take the teaching of ”ellipse and its standard equation" as an example, from the creation of the problem situation; the formation of the concept; the establishment of a mathematical model to enable students to experience the formation of three levels, while enriching students’ learning styles .Draw
