引导启发式混合教学在物理化学实验中的探索——以电极制备及电池电动势的测定为例

Exploration on Mixed-teaching Method by Guidance and Inspiration in Physical Chemistry Experiment——Taking Electrode Preparation and Electromotive Force Measurement of Battery as Example

采用信息技术支撑的物理化学实验混合教学模式,贯穿引导启发式教学理念,以《电极制备及电池电动势的测定》为案例,首先引导学生思索已学电化学知识,通过实验设计步骤引导自主实验操作,启发学生自主开展探索电极制备和电动势测试的内在知识,深层次启发学生主动探索该实验的本质,激发学生对实验方法优化改进,升华理论知识。从而实现学生为中心和知识传授及能力培养的内核,提高学生自学水平和动手能力,增强学生综合技能素质。

Mixed-teaching method of Physical Chemistry experiment supported by information technology was adopted,and guidance and inspiration ran through the teaching idea.Electrode preparation and electromotive force measurement of battery was taken as an example in order to explore design of the teaching idea.First,students were guided to preview electrochemical knowledge that they had learned,and then students were required to operate the experiment independently through the design steps of experiment.We inspired students to explore the internal knowledge of electrode preparation and electromotive force test,and deeply urge students to actively explore the essence of experiment.Students werestimulated to optimize and improve experimental methods,and thus sublimate theoretical knowledge.Students were highlighted as the center and knowledge teaching and ability training as the core were realized.Students self-study level and practical ability were improved,so as to further enhance their comprehensive skill quality.
