基于超星学习通的化学实验教学模式的探索——以“醋酸电离度与电离常数的测定”为例

Exploration of the Teaching Model of Chemistry Experiment Based on Superstar Learning——Take"Determination of the Ionization Degree and Ionization Constant of Acetic Acid"as an Example

实验教学是化学教学中的生命,但传统的实验教学模式存在很多弊端,在互联网教学迅速发展的今天,线上线下的混合教学模式带来了教学方式的变革,学生通过线上实验课程的学习极大提高了预习效率,实现了线上学习和线下操作的有机结合,提高了学生自主学习的效率和实践能力。本文以“醋酸电离度与电离常数的测定”为例,学生使用超星学习通在线上预习、测试,测试合格后再进实验室,激发了学生的学习主动性,加强了师生线上互动交流,促进了教学效果的改善。

Experimental teaching is the life of chemistry teaching,but the traditional experimental teaching model has many drawbacks.Today,with the rapid development of Internet teaching,the online and offline mixed teaching model has brought about changes in teaching methods.Students learn through online experimental courses.It has greatly improved the efficiency of pre-learning,realized the organic combination of online learning and offline operation,and improved the efficiency and practical ability of students'independent learning.This article takes"the determination of ionization degree and ionization constant of acetic acid"as an example.Students use super star learning pass to preview and test online,and then enter the laboratory after passing the test,which stimulates students'learning initiative,strengthens the online interaction between teachers and students,and promotes the improvement of teaching effect.
