在高中数学课堂教学中,如何科学地设置问题,是提高课堂教学有效性的关键。一个精彩问题的设置,必须做到:难度要适中,问题背景必须是学生熟悉的,呈现的时机要适当,既要具有有趣味、挑战性,还要具有实际意义,对学习、理解、掌握、应用前后数学知识有很好的作用。设计的问题必须具有导向作用,必须具有针对性,有利于学生成功地构建数学理论;有利于学生对数学知识和数学方法的整合;有利于培养学生的探索精神和创新意识,有利于面向全体学生,因材施教。
In high school mathematics classroom teaching, how to set the problem scientifically is the key to improve the effectiveness of classroom teaching. The setting of a wonderful problem must be: the difficulty is moderate, the background of the problem must be familiar to the students, and the timing of the presentation should be appropriate. It is not only interesting and challenging, but also has practical significance. It is necessary to learn, understand, master, Before and after the application of mathematical knowledge has a very good effect. The design problem must have the guiding function, must have the pertinence, is advantageous to the student successfully constructs the mathematics theory; Is advantageous to the student to the mathematics knowledge and the mathematics method conformity; Is advantageous in cultivating the student exploration spirit and the innovation consciousness, is advantageous to the entire student , Teaching students according to their aptitude
