How to Implement the Practice of "Researching Learning" in Chemistry Class Teaching

从“研究性学习”作为一门必修课程提出了对化学课堂教学中实施“研究性学习”的构想;并以过氧化钠与水反应后溶液滴加酚酞试剂产生异常现象的探究课例实践阐述。

As a reauired course,' Researching Learning' advances the conception on how to implement the practice of Researching learning in Chemistry Class teaching, in order to expound the conception, the author studys the soludon produced by reaction between Na2O2 and H2O and deeply researches the abnormal phenomena of solution which is dropped into phenolphthalein test reagent,by means of results above,author gives following statement.
