在新课标下高中数学教学中,教师需用适当题量,训练学生的转换思维能力,引导学生通过一类问题性质对其他类型的问题加以研究.构造法体现了思维的转换,在构造法中,其核心是依据已知条件特点来恰当、灵活地构造其他新形式.换而言之,在解数学问题时,当运用常规方法难以求解时,则可依据题设特点进行联想,找出其他思路与方法来解题.一、构造函数解答数学问题在高中数学中,知识点是十分丰富的,并且各知识之间也有着密切关系,环环相扣.在数学学习过程中,若学生能够从整体上把握,懂得将不同知识加以联系,才能活用知识,学好数学.在数学知识中,一些问题表面似乎和其他知
Under the new curriculum standard of high school mathematics teaching, teachers need to use appropriate questions to train students’ ability to transform thinking and guide students to study other types of questions through a kind of question nature.The constructive method embodies the transformation of thinking, , Its core is based on the known conditions and characteristics to properly and flexibly construct other new forms.In other words, when solving the mathematical problems, when using the conventional method is difficult to solve, you can find the association Other ideas and methods to solve the problem. First, the constructor to answer mathematical problems In high school mathematics, knowledge points are very rich, and there is a close relationship between the knowledge, interlocking.In mathematics learning process, if the students To grasp the whole, know how to contact different knowledge, to use knowledge, learn mathematics.In mathematical knowledge, some of the problems seem to surface and other knowledge
