《普通高中数学课程标准(实验)》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、自主探究、动手实践、合作交流、阅读自学等都是学习数学的重要方式。”为此,丰富学生的学习方式、改进教学方法,打造课堂的有效性成为新课程改革背景下高中数学课程追求的基本理念。 The “General High School Math Curriculum Standard (Experiment)” states: “Students' mathematics learning activities should not be confined to the memorization, imitation and acceptance of concepts, conclusions and skills, independent thinking, self-exploration, hands-on practice, cooperation and exchange, reading self- Are all important ways to learn mathematics. ”Therefore, enriching students' learning methods, improving teaching methods and building classroom effectiveness have become the basic ideas pursued by high school mathematics curriculum in the context of the new curriculum reform.
