浅析物理化学实验课对理论课教学的促进作用——以蔗糖水解反应数据处理为例

Promoting effect of experiment on theoretical teaching of physical chemistry taking sucrose hydrolysis reaction data processing as an example

探究物理化学中的实验数据信息,以蔗糖水解反应实验为例并结合相关理论知识进行反应级数的反推求算,关注学生对物理化学理论教学中几种反应级数测定方法的理解.结果表明,在物理化学实验中用理论知识分析讨论实验数据和结果能够很好地促进学生对理论知识的理解,极大地提高学生实验积极性,并在培养学生综合素质方面取得了成效.

Taking sucrose hydrolysis reaction experiment as an example,the data from physical chemistry experiments is explored.The reaction progression is calculated with the relevant theoretical knowledge.The students’ understanding of several reaction series determination methods in the teaching of physical chemistry theory is analysed.The findings show that experiments promote the students’ understanding of theories,enhance students’ motivation in experiments and their comprehensive qualities by analyzing experimental data and results in physical chemistry experiments.
