摘要
将本科基础实验中产生的甲醇废液,用于开发探索性教学实验。在实验中,学生自行搭建反应装置,设置不同反应条件,得到不同实验结果,并利用多种常规仪器和大型仪器进行未知样品分析。实验强调学生的主动性,引导学生综合利用现代分析手段,探索实验现象的起因,培养学生的科学思维和动手能力,克服了传统实验教学偏重于验证性实验的不足,为化学基础实验改革提供了新的方法和思路。
Lab wastewater containing methanol was utilized to develop an exploratory experiment for undergraduates. In the experiment, students were required to build up apparatus, carry out reactions and analyze samples. Several instrumentations were used by students for sample analysis. The experi- ment stresses not only the capability of lab practice but also the logical thought of science research in- cluding observation, investigation and conclusion.
