高中二年级信息技术课的教学内容中介绍了有关数据表处理的知识(人教版高二的课本是以Excel 2000为例的)。按以往的教学方法,我们会逐节按部就班地教学,但由于教学内容较多,知识点比较零散,全部内容学习完之后,学生头脑中很难形成一个整体的概念,有的学生学完之后连处理一些简单的表格内容都有困难,教学效果并不好。为了增强教学的直观性和效果,课前,我制作了学生们非常熟悉的值周统计表(下表)。
The teaching content of the second grade information technology course in senior high school introduces the knowledge of the data table processing. According to the previous teaching methods, we will follow the instruction step by step, but due to the large number of teaching materials and relatively scattered knowledge points, after the completion of all the contents, it is difficult for students to form an overall concept in their minds. It is difficult to deal with some simple forms and the teaching effect is not good. In order to enhance the intuitiveness and effectiveness of the teaching, before the class, I produced a weekly statistics table (the table below) that students are very familiar with.
