极限思想在高中数学教材中多处出现,并呈现出螺旋式上升的状态,学生在初次模糊接触、感知到逐渐运用,直至熟练掌握并用以解决实际问题的过程中,思维得到了不断的锻炼和提升,并从量变达到了质变,充分认识到数学的无穷魅力。在近几年的高考试题中,频频出现了利用极限思想解决问题的试题,因此极限思想越来越得到师生的高度关注和重视。下面,笔者总结了极限思想在教学中的渗透要点,与读者交流。
The limit thinking appears in many places in high school mathematics textbooks and shows a spiraling state. Students make the initial use of the fuzzy touch and perceive them gradually until they are mastered and used to solve practical problems, and their minds are continually trained Enhance, and qualitative change from quantitative change, full recognition of the infinite charm of mathematics. In recent years, college entrance examination papers, frequently appeared to use the limit thinking to solve the problem, so the limit thinking more and more teachers and students get the attention and attention. The following, the author summarizes the essentials of teaching in the infiltration of essentials, and readers exchange.
