数学往往与解题是分不开的。教师在教学过程中使出了各种招数,精心准备了各道“盛宴”给学生品尝,而学生却在无穷无尽的“题海战术”中疲惫不堪。究其原因,一方面是由于高中数学内容跨度大,抽象性强;另一方面由于多数学生对数学学习都是浅尝辄止,不够深入。如果师生能够加强互动,全面交流,实现教学相长,师生双方就能更好地把握数学。本文拟以圆锥曲线的教与 Mathematics is often inseparable from problem solving. Teachers used various tricks during the teaching process and carefully prepared various “feasts” for the students to savor. However, students were exhausted in endless “sea tactics”. The reason for this is on the one hand because of the large span of high school mathematics content and its strong abstraction; on the other hand, because most students are learning about mathematics, they are not deep enough. If teachers and students can strengthen interaction, fully communicate, and achieve teaching expertise, both teachers and students can better grasp mathematics.
