决定学生做题是否顺利的一个关键性的因素是解题方法的选择,能否在第一时间选择正确、恰当的最优解题方法对学生来说至关重要.方法选择错误会使解题过程受阻,纵使绞尽脑汁也止步不前.解题方法选择正确但不恰当则会使计算过程繁琐,解题时间太长会影响做其它题目,无形之中降低了解题效率.笔者所在的学校是山东省一所县级重点高中,针对山东省2016年理科第20题的第(Ⅱ)问,调查高三毕业的理科生发现,此函数大题貌似简单,但
One of the key factors that determine the success of a student’s questioning is the choice of problem-solving method, and it is very important for the student to choose the correct and appropriate method of optimal problem solving at the first time. The process is blocked, even though brains are also halted.The choice of correct method of problem-solving method is not appropriate but will make the calculation process cumbersome, the problem-solving time is too long will affect other topics, invisible to reduce the problem-solving efficiency. The school is a county-level key high school in Shandong Province, Shandong Science 2016 Question 20 (II) Q, the investigation of science graduates found that the function of the big problem looks simple, but
