南北朝的萧统在《纂要》提到“一年之计在于春,一天之计在于晨”。我们把这句脍炙人口的名句引用到我们的教学也是无可厚非的。新的课程改革也接近尾声了,回想这八次的课程改革,我们可以看出:“问题情境”仍是每一次课改的重要内容。当然,具体到数学这门特殊的自然科学,“问题情境教学”也是经历了曲折的漫长的岁月。一堂好的数学课,“问题情境”这一环节的设置显得尤为重要。问题是学生学习的原动力、内驱力,没有问题的学生永远都不会是最好的学生。当然,作为教师要在学生没有问题的情况下,要给学生创设一定的问题情景。本文就征对数学“问题情境”教学,从“问题情境”的含义和作用、创设问题情境的必要性、创设有效问题情境的策略等方面去分析讨论。
Southern and Northern Dynasties Xiao Tong in the “compilation” mentioned “a year’s plan is in the spring, the day’s plan is in the morning ”. It is understandable that we quote this famous quote to our teaching. The reform of the new curriculum is also coming to a close. Recalling the eight-time curriculum reform, we can see that “the problem context” is still an important part of every curriculum reform. Of course, specific to the special natural science of mathematics, “problem situation teaching” is also experienced a long twists and turns years. A good math class, “problem situation ” this part of the setting is particularly important. The problem is the driving force behind student learning, internal drive, students without problems will never be the best students. Of course, as a teacher, students should be given no problems in the circumstances, to create a certain problem scenarios for students. In this paper, the author expounds the meaning and function of “problem situation”, the necessity of creating problem situation, the strategy of creating effective problem situation and so on.
