1.结论的产生复习完抛物线的相关内容后,学生普遍感到所学知识比较零散,缺乏对知识的内在联系的理解和掌握,解决比较复杂的问题时没有头绪。究其原因,主要是对一些结论掌握得不够透彻,解题时缺乏联想。为此,又安排了一节复习课,通过对两个典型例题的研究,对抛物线中的一些重要结论做了进一步的探讨,学生课堂表现非常活跃,并创造性的提出了一些重要的结论。 1. Conclusions After reviewing the relevant contents of the parabola, students generally felt that the knowledge they learned was rather fragmented, that they lacked the understanding and mastery of the intrinsic linkages of knowledge, and that they had no clue about the more complicated issues. The reason is mainly due to lack of thorough understanding of some of the conclusions, lack of association when solving problems. To this end, we also arranged a review class. Through the study of two typical examples, we further discussed some important conclusions of the parabola. Students' classroom performance was very active and creatively made some important conclusions.
