“聚焦课堂”是当前教育、教学研究的方向,这已在教育界达成共识。中国有句俗语:“授人以鱼,莫若授人以渔。”意思就是说:给人吃鱼,不如教他学会捕鱼的方法。对于数学课堂也是如此,是授人以鱼还是授人以渔?在科学技术日新月异的今天,技术的发展、应用的增多、计算机的影响,以及数学自身的发展大大拓展了数学的范围和应用。越来越多地渗入到各个领域,使得数学教学在教育中显得尤为重要。所以应更好地研究数学课的教学方法,使学生更好地掌 “Focus on the classroom ” is the current education, teaching and research direction, which has reached a consensus in the education sector. There is a Chinese proverb: “To teach people to fish, Mo to teach people to fish. ” The meaning is that: giving fish, it is better to teach him how to learn to fish. The same is true for the math class, is to teach people to fish or grant to fish? In the ever-changing science and technology today, the development of technology, increased applications, the impact of the computer, as well as the development of mathematics itself greatly expanded the scope and application of mathematics. More and more infiltration into all fields, making mathematics teaching in education is particularly important. Therefore, we should better study the teaching methods of math class so that students can better grasp it
