三角形是数学家族中的一个重要分支,是人们早已熟知了的图形,它常被用于生活和生产实践中,时常被作为数学问题的背景来提出,并与其他数学知识结合起来以考查人们综合分析问题和解决问题的能力,引起人们的高度重视。从三角形“五心”的实践教学出发联想到如何以研促教,加强应用教学,以提高数学教学的实用效率。
Triangles, an important branch of the mathematical family, are well-known figures that are often used in life and in production practice, are often presented as a background to mathematical problems and combined with other mathematical knowledge to examine people’s synthesis Analysis of the problem and the ability to solve the problem, aroused people’s attention. Starting from the practical teaching of the triangle “Five Hearts ”, I think of how to promote research and teaching and strengthen the application of teaching so as to improve the practical efficiency of mathematics teaching.
