基于微信公众号构建无机化学实验微课平台的研究与探索

Research and Exploration on the Construction of Inorganic Chemistry Laboratory Micro-Course Platform Based on WeChat Public Account

微课是在信息化时代和新教学理念下提出的新型教学模式,针对无机化学实验教学的现状,利用微信公众号构建微课平台,辅助教师进行课堂教学,解决了无机化学实验教学中安全培训、学生预习、学时少及实验内容多、实验药品购买使用受限、不能做有毒实验等问题。通过微课教学还实现了实验内容多样化、演示操作可视化,从而提升学生学习的主观能动性,增强动手能力,规范实验操作流程,便于学生对实验重点难点的掌握,同时增强师生交流,满足各层次学生要求,提高课堂效率。

A new teaching model,micro-teaching,is proposed in era of information,and the new teaching design philosophy focusing on the features and the present situation of inorganic chemistry laboratory teaching,micro class platform was built by using WeChat public account to assist the classroom teaching.It solved the problem of the inorganic chemistry laboratory teaching,such as the safety training,students’preview,more contents but less lecture time,limited resource of experimental reagents,lack of the protection from toxic reagents.Through micro-teaching,experimental content diversification and demonstration operation visualization were realized.It improves students’subjective initiative in learning,strengthens their hands-on ability,standardizes the experimental procedures,facilitates students to grasp the key and difficult points of the experiment,strengthens the communication between teachers and students,meets the requirements of students at all levels,and improves the efficiency of the classroom teaching.
