数学课堂教学在传授数学知识的同时,更重要的是提升学生的数学素养,即学会阅读、学会归纳与整理、学会质疑、学会思考、学会研究等.笔者以为,联想和类比是落实这些“学会”的行之有效的手段之一.下面从一个问题出发,展示研究性学习的思维过程.问题直线l:x/a+y/b=1(a>0,b>0)与x轴、
While teaching mathematics knowledge in mathematics classroom teaching, it is more important to improve students’ mathematical literacy, that is, to learn to read, to learn to summarize and organize, to learn to question, to learn to think, to learn to study, etc. The author believes that associations and analogies implement these “ Learning ”one of the effective means of the following starting from a problem, demonstrating the process of thinking of the study of learning the problem line l: x / a + y / b = 1 (a> 0, b> 0) and x axis,
