从教学法規点来看权限理论是中学数学课的最困难的章节之一。涉及到的概念的新奇和抽象常常使学生仅仅形式地掌握这一理论,看不出与他們在学校里所学的东西的联系和与他們周围生活中的事物的联系。这些不能容忍的缺点由于在中学課程中引进了高等数学因素就变得特別危险了,要知道,不真正掌握极限概念就不可能理解什么是导数或积分(虽然积分还沒有列入中学大綱,但是希望这次改革不会半途而 Judging from the points of teaching regulations, the theory of rights is one of the most difficult chapters of mathematics lessons in middle school. The novelty and abstraction of the concepts involved often led students to grasp this theory in a form only, not seeing the connection with what they learned in school and the connection with things in their surrounding life. These intolerable disadvantages are particularly dangerous because of the introduction of higher mathematics factors in the secondary school curriculum. It must be understood that it is impossible to understand what are derivatives or integrals without really grasping the concept of limits (although the points have not yet been included in the secondary school syllabus, but I hope this reform will not happen halfway
