数学中并不缺少美,而是缺少欣赏数学美。欣赏均值不等式,就是欣赏其体现出来的几何之形态,代数之神韵,思辨之简洁,应用之和谐,让人心旷神怡。“欣赏,是教育的一部分。欣赏是需要指导、培育的”~([1])。因此,张奠宙先生指出“数学教育是为了欣赏数学文化和数学思维的真善美”。然而,工作在一线的数学教师,大多数将数学教育重点放在了如何做题上,强调怎样才能既快又准确的解题,很少从欣赏的角度去认识所讲的数学知识,这不得不说是数学教师 Mathematics is not lack of beauty, but the lack of appreciation of mathematical beauty. Appreciation of mean inequality, is to appreciate the shape of its geometry, algebraic charm, concise speculation, the application of harmony, people relaxed and happy. “Appreciation is part of education. Appreciation is the need to guide and nurture ” ~ ([1]). Therefore, Mr. Zhang Dian-zhou pointed out that “Mathematics education is to appreciate the truth, kindness and beauty of mathematical culture and mathematical thinking.” However, the math teachers who work in the front line, most of them focus on how to do math education, stressing how to solve the problem quickly and accurately, and rarely understanding math knowledge from the perspective of appreciation. Not to be a math teacher
