新旧人教版化学教材对比--以钠及其化合物为例

Contrastive Study of New and Old Human Education Textbooks on Chemistry--Taking Sodium and Its Compounds as an Example

本论文以金属钠及其化合物为例,对新旧教材进行对比。通过对知识呈现方式、导入、图表、栏目、习题进行分析,发现旧版教材知识呈现主要按专题进行,让学生按块学习,但习题、栏目类型较少,知识难度相对较大,与生产生活联系不够紧密。而新版教材突出分类思想,知识呈现按类别进行,栏目丰富,但习题难度稍大,更注重物质的性质、结构、用途之间的关系。通过对两版教材的比较,希望能给化学教师在使用化学教材时提供更多参考。

This paper takes metal sodium and its compounds as an example to compare the old and new textbooks.Through the analysis of the way of knowledge presentation,introduction,charts,columns and exercises,it is found that the knowledge presentation of the old textbooks is mainly carried out according to the topic,so that students can learn by blocks,but there are fewer types of exercises and columns,the knowledge is relatively difficult,and it is not closely connected with production and life.The new version of the textbook highlights the idea of classification,knowledge presentation according to categories,columns rich,but the difficulty of exercises is slightly bigger,pay more attention to the nature of the substance,structure,the relationship between the use.Through the comparison of the two textbooks,we hope to provide more references for chemistry teachers when they use chemistry textbooks.
