在圆锥曲线的教学中,教师有目的有意识地引导学生总结一些性质,并谈性质在解有关题目的应用.这样不仅活跃了学生的思维、拓宽了思路,而且激发学生的求知欲望,培养了学生的探索能力.利用课外辅导时间,长期坚持下去,造成良性循环,有利于学生智力的发展和数学能力的提高.为此,本文介绍圆锥曲线的一个有趣性质及其应用,供教学参考.
In the teaching of conic curves, teachers purposefully guide students to summarize some of the qualities and discuss the nature of the application of the relevant topics. This not only invigorates students’ thinking and broadens their thinking, but also stimulates students’ desire for knowledge and trains students. The ability to explore. The use of private tutoring time, long-term adherence, resulting in a virtuous circle, is conducive to the development of students’ intelligence and the improvement of mathematics ability. For this reason, this article introduces an interesting feature of conic curve and its application for teaching reference.
