摘要
遵循实验改进的科学原则,立足中学化学教学实际,对文献中“木炭还原氧化铜”的实验改进从反应物的选取、热源和反应装置3个方面分类比对、分析.结合教学实际对该实验进行了显性化设计,提出具体改进建议.
According to the scientific principles for experiment improvement and based on the practice of high school chemistry teaching, this paper compared and analyzed these experiment improvements regarding "reduction of cupric oxide by charcoal" in literatures from three aspects respectively, including selection of reactants, heat source and reaction apparatus. Through combining with the teaching practice, this paper also made an explicit design for the experiment and put forward specific suggestions for improvement.
