Abstract |
In this study, we compared the content of textbooks of 2009 revised curriculum with the contents of textbooks of 2015 revised curriculum in order to check whether there is a change in "development and use of model" which is emphasized in 2015 revised curriculum. To do this, we analyzed 4 kinds of chemical Ⅰ textbooks and 4 kinds of chemistry Ⅱ textbooks in the revised 2009 curriculum and compared them with 7 kinds of chemistry Ⅰ textbooks and 5 kinds of chemistry Ⅱ textbooks in 2015 revised curriculum. The scope of the analysis was focused on only the explanations and experiments presented in the textbooks. In order to compare the contents of electrolyte, we analyzed contents of 9 kinds of middle school science textbooks of 2009 revision curriculum and 3 kinds of middle school science textbooks of 2015 revision curriculum. As a result of the analysis, the same experiment was explained by different models according to grade and unit, and all explanations were limited to a single model. Also, the tendency to limit the use of electrolytes with experimental results, which may not be consistent with the model, is more pronounced in the 2015 revised curriculum than in the 2009 revised curriculum. These results suggest that emphasis should be need the "development and use of models" in textbook experiments and explanations of the 2015 revised curriculum. |
