一尝试的目的:为何要上一节数学活动课“函数”这一内容是高一新生进入高中后的第一章内容,也是高中数学的重点,还是学生感觉学习最为吃力的部分。因为他们不重视函数图像的问题,有的学生或许根本就没有数形结合的数学思想。因此,在初二学完函数、一次函数之后把和教材配套的《数学活动》中的“看图说话”这节课穿插进去,目的是想进一步巩固一次函数、一元一次方程、一元一次不等式之间的联系和转换;更是想看看学生在“图”上知识的迁移能力,能否利用数形结合的思想方法去解决其他还未学过的函数问题;也想在学生的能力上提高一个层次,
The purpose of the attempt: Why do you want to go to the previous section of the math activity class “Functions” This is the content of the first chapter of a freshman’s entry into high school. It is also the focus of high school mathematics, or the most difficult part of student learning. Because they do not pay attention to the problem of functional images, some students may not have a combination of mathematical ideas. Therefore, after the completion of the function and the first function in the second year of the second year, the lesson “Making words” in the “Mathematical Activities” that is associated with the teaching materials was inserted in order to further consolidate the first function, the one-ary-one equation, and the one- The connection and transformation between inequalities; more is to look at the students’ ability to transfer knowledge on the “graph”, whether they can use the combination of number and shape to solve other problems that have not been studied; also want to be students.
