综合性化学实验教学设计与探索——碳量子点的制备及在四环素定量分析中的应用

Comprehensive Chemical Experiments Teaching Design and Exploration:Preparation of Carbon Quantum Dots and Their Application in Quantitative Analysis of Tetracycline

针对应用创新型人才培养要求,为高年级本科生增设综合性化学实验课程,旨在培养学生综合运用知识的能力和科学研究的素养。根据课程特点,开设“碳量子点的制备及在四环素定量分析中的应用”设计实验项目,通过文献查阅、原理阐述、方法研究、性能测试、分析结果等实验环节,学生可掌握纳米材料的水热制备技术、仪器表征的基本手段、复杂样品定量分析的一般步骤等。课程内容贴合科学前沿热点,课程设计以学生为主体,促进以“需求”和“问题”为导向的教学模式,有助于激发学生的学习兴趣,培养创新实践能力。

In order to meet the requirement of cultivating innovative talents,comprehensive chemical experiment course should be set up for senior undergraduates,aiming at cultivating students’ability of comprehensive knowledge application and accomplishment of scientific research.Taking the experiment“preparation of carbon quantum dots and their application in quantitative analysis of tetracycline”as example,through literature review,method study,performance testing,and results analysis,students can master the preparation technology of nanomaterials,instrumental characterization and general steps of quantitative analysis of complex samples,etc.The course content joints scientific frontier spots and curriculum design takes the students as main body.The teaching mode oriented by“need”and“problem”is helpful to stimulate students’interests and cultivate their innovative practical ability.
