摘要
以高中"实验化学"模块的"海带中碘元素的分离及检验"为例,依据权威性、针对性与可读性的原则,选取符合要求的文献,创设情境组织教学。学生们在文献阅读与分析的过程中,多角度认知海带处理、氧化剂选择、碘单质提纯与检验等,体会使用文献的价值。实践证明在教学中引入文献,有利于开拓学生视野,提升学习兴趣。
Based on the principles of authoritativeness, pertinence and readability, the paper took the "isolation and testing of iodine elements in laminaria japonica" as an example, relevant and qualified literature were selected to create contexts for further teaching. During reading and analyzing literature, students realized the value of them. Literature guided students in various aspects such as laminaria japonica pretreatment, selection of oxidants, purification and identification of iodine. It has been proved that literature contribute to broaden the horizons of students and inspire their interest a lot.
