基于网络构建的仪器分析实验立体化教学研究

Constructing Multiple Teaching System of Instrumental Analysis Experiment Based on Network Platform

针对目前仪器分析实验教学中存在的学生不预习实验、实践机会少、成绩考核和教学评价不能完全量化等主要问题,开展了基于网络平台的、从实验预习到科研应用的仪器分析实验立体化教学研究。学生上网预习实验并考试,教师通过网站出题并分析试卷,找出教学薄弱环节,将“提问互动式”实验教学与网络平台辅助教学有机地结合在一起。经对比实践研究,采用教改方式学习的学生,其平均成绩提高了2.26分,对基于网络的立体化教学对创新型和应用型人才培养起到了积极作用。

There are several problems in the current experimental teaching of instrumental analysis.Students are not motivated to preview the experiment and have rare opportunities to practice.The student achievement assessment and teaching evaluation cannot be well quantified.To solve these problems,the multiple teaching system of instrumental analysis experiment was constructed for students based on a network platform from previewing the experiment to practicing in scientific research.A number of teaching stages have been implemented,including the exam,setting papers for examination,instrument booking for research purpose,and examination paper analysis to find out the weak link of teaching.It is necessary for the“question-answer”teaching in laboratory and network platform aided teaching to be combined together.Through practice researching,the average score of the students taught by the reform method was increased by 2.26 points.The multiple teaching system based on the network platform can play a positive role in training innovative and application-minded talents.
