初中数学中的“实际问题”以方程(组)、不等式(组)、函数等为基本数学模型.如何设置恰当的“问题”或“问题串”进行课堂教学,将有助于开拓学生的思维,提高学生运用数学知识解决问题及语言表达能力:有助于把握课堂的生成性资源,不断地调控课堂教学,激发学生对数学学习的兴趣.从而使得教师的“教”与学生的“学”完美结合,达到“教”与“学”共赢.1_以“问”导引揭示课题.苏霍姆林斯基曾说过“思维是从疑问开始的,只
In junior high school mathematics ”practical problems “ to the equation (group), inequality (group), the function as the basic mathematical model.How to set the appropriate ”question“ or ”question string “ for classroom teaching, there will be Help to develop students’ thinking and improve students’ ability of using mathematics knowledge to solve problems and express their language: help to grasp the productive resources of the classroom, constantly regulate classroom teaching and stimulate students’ interest in mathematics learning. ”And student “ learning ”perfect combination, to achieve “ teaching ”and “ learning ”a win-win situation.1_“ ”asked “ to reveal the subject.Suhomlinski said ”Thinking is from doubt, only
