摘要
结合农业院校特色和应用化学类专业特点,将科研成果转化为实验教学内容,设计"绿色水热法快速制备荧光碳点"的创新性化学实验。通过本实验项目,学生可了解水热法和碳点相关制备方法及表征技术,掌握透射电镜、荧光光谱仪等大型仪器的结构、原理及操作技能,增强学生的基础知识和实验技能;同时将当前的研究热点引入到实验教学中,激发了学生的探究心理与学习热情,开阔了学生视野,有利于培养学生发掘身边可用资源的科研思维和创新实践能力,提高了学生解决实际问题的能力,开启了农业院校研究型创新化学实验教学模式的新思路。
Combining the characteristics of agricultural university and the specialty of applied chemistry,and in order to convert the scientific research achievements into the experimental teaching contents,an innovative chemical experiment of ＂rapidly preparation of fluorescent carbon dots by green hydrothermal method ＂ was designed. The preparation methods and characterization techniques of the hydrothermal method and carbon dots were well annotated in the project. On the other hand,the structure,working principle and operation skills of large-scale scientific instruments such as transmission electron microscope and fluorescence spectrometer were elaborated. Moreover,experimental teaching closely integrates with scientific research,it can not only stimulate students＇ inquiry psychology and study interests,broaden their horizons,but also cultivate students＇ innovative practical capabilities and scientific thinking. With the improvement of students＇ competence in solving problems,they will open a new path to modified teaching mode of the research innovative chemistry experiment in agricultural universities.
