对于苏教版选修2-2第1.2.1“常见函数的导数”的内容,课本是这样安排的.先给出求函数导数过程的流程图,再推导一次函数、几个幂函数的导数,从而给出基本初等函数的求导公式,最后练习、习题.这一过程是将各种求导公式按课本的顺序呈现出来,由于学生的知识准备还不够,且课本中不能展示知识的发生发展过程,也无法告诉学生这部分知识的来龙去 For the content of the 2.2.1“derivatives of common functions” of Jiangsu Elective Elective 2-2, the textbooks are arranged in this way. First, the flowchart of the process of finding the derivative of the function is given, and then the function and several power functions are deduced. Derivatives, which give the formula for the derivation of basic elementary functions, and the final exercises and exercises. This process is to present the various derivation formulas in the order of textbooks, because students’ knowledge is not enough and the textbooks cannot show knowledge. The development process can’t tell students about the ins and outs of this part of the knowledge.
