问题教学,是数学课堂中最常用的教学方式,著名教育家陶行知先生说过一段名言:“发明千千万,起点在一问,智者问得巧,愚者问得笨.”教学中一个巧妙的问题,往往可以立即打开学生的思维闸门,使他们思潮起伏、奔腾向前,有所发现并顿悟,收到“一石激起千层浪”的教学效果.精彩的问题才会产生成功的教法,因此教师要精心预设教学问题环节,使课堂精彩纷呈,提高课堂教学质量.本文拟以一节区级公开教学课《二次函数2
Question teaching is the most commonly used method of teaching in mathematics classrooms. Mr. Tao Xingzhi, a famous educator, has said something famous: “The invention of tens of millions starts from a question, the wise men ask conscientiously, the fools ask dumb things.” In a clever question, you can often immediately open the student’s thought gate, so that their ups and downs, Pentium forward, some discovery and epiphany, received “a stone aroused Melaleuca wave” teaching effect.
