物理化学实验多方案激励式教学法

Multi-program Incentive Teaching Method in Physical Chemistry Experiments

物理化学实验是一门综合性研究性较强独立设课的实验课程,学生来自不同学院不同专业,化学知识计算机知识程度不同。市售仪器高度智能化,直接给出结果。实验教材中通常是一种实验方案。设计采用多方案激励式教学法,以溶解热测量和BZ振荡反应实验为例,改制仪器设备,编写软件,在一个实验项目中设计多种实验方案,难度不同,学生可以单选,也可以多选,选择不同的方案得到不同的成绩,激励学生挑战自我。大部分学生先选择容易的方案,再选择更难的方案,进一步学习理解实验原理,练习用通用软件处理数据,按照更难的方案完成实验报告,提高了实践研究及创新能力,激发了进一步学习探索的热情。

Physical chemistry experiment is a comprehensive research expe：iment course. Students come from different schools with different majors. Their chemistry and computer knowledge is also different. Commercially available instruments are highly intelligent, and the results are given directly. Multi-program incentive teaching method is designed in the paper, for example, the dissolution heat and BZ reactions, it requires students to restructure equipment, write software. Multi-program with different difficulties is designed in an experimental project. The students themselves choose the program, one or more options. Different programs lead to gel different grades, and motivate students to challenge themselves. Most of the students first choose the easy program, tlaen choose the program more difficult, study and understand more experimental principles, data processing by common software, report writing. It can improve the ability of students in practice and scientific research.
