菱锰矿脱氯实验教学研究
|
摘要
为激发学生对无机实验的学习兴趣,培养学生学习的主观能动性,该文对无机实验教学的内容进行了丰富和完善,将菱锰矿脱氯研究设计成探索性实验引入无机实验教学中,并适当增加实验难度,让学生根据所学知识自己探索实验条件,同时考虑到实验的时长和复杂性,对学生进行分组,由学生自行分配时间,分工协作来完成实验,从而得出正确的实验结论。实践表明,该设计实验不仅提高了学生的实验素养和研究能力,还增强了学生的合作意识和合作能力。
In order to ignite the students' interest in learning of inorganic experiment,and develop the students' subjective initiative to learn,the content of inorganic experimental teaching has been enriched and perfected.The rhodochrosite dechlorination study has been designed exploratory experiment and introduced into inorganic experiment teaching,the difficulty of experiment has been enhanced suitably,the student was required to grope for conditions according to their study.While considering the length and the complexity of the experiment,the students were grouped,and allocated time and work by themselves to complete the experiment.Through teaching practice,it is found that the design experiment not only improves the students' experimental literacy and research ability,but also enhances students' cooperative consciousness and cooperation ability.
