一道好的压轴题,既要体现数学知识、技能与经验、能力的内在价值,又要体现数学的人文价值,关注学生的精神世界、情感需求和个性差异,使之成为学生与知识、情景、命题者(教师)之间自然对话的良性载体,成为心灵交汇、情感交流的畅通渠道。压轴题是经过命题者精心编制,具有典型性、示范性、拓展性、研究性。只有教师认真钻研,学会拓展延伸、类比迁移,才能让自己从单纯的执行者转变为开发者,从而更好地训练学生的创造性思维,教学也必将更加有效。 A good finale is not only to reflect the intrinsic value of mathematics knowledge, skills and experience, but also to reflect the humanistic value of mathematics, to pay attention to the students’ spiritual world, emotional needs and personality differences, making it a student and knowledge, Proponents (teachers) of the natural dialogue between the benign carrier, as the heart of the exchange of emotion, smooth communication channels. Finale of the title is carefully prepared by the proponents, with a typical, exemplary, expanding, research.
