一、关于知识逻辑和结构方面的比较分析知识逻辑和结构有助于我们认识“重力”这节内容的整体框架,所以,我们先从知识逻辑方面进行比较分析,各个版本的情况如表1所示。由表1可知,“重力”内容主要的知识逻辑是:重力的概念、重力的大小、重力的方向、重心。《义务教育物理课程标准(2011年版)》对“重力”内容的要求是:通过常见事例或实验,了解重力,认识力的作用效果。要使学生了解力,就必须知道力的三要素,然而,
First, the comparative analysis of the logic and structure of knowledge Knowledge logic and structure help us to understand the overall framework of the content of this section. Therefore, we first make a comparative analysis on the logic of knowledge. The various versions are shown in the table 1 shown. As can be seen from Table 1, the main logic of knowledge of “gravity” is: the concept of gravity, the size of gravity, the direction of gravity, and the center of gravity. The compulsory education physics curriculum standards (2011 edition) “on the” gravity "content requirements are: Through common examples or experiments, understand the effect of gravity, cognitive effect. For students to understand the power, they must know the three elements of power. However,
