碱式碳酸铜制备实验的教学设计

Teaching Design of Preparation of Cupric Subcarbonate

针对传统实验教学中存在的＂教师讲授-学生实验＂的验证模仿式教学模式的弊端,以实验教学目标的多维化和建构主义学习理论为教学设计的理念指导,设计了碱式碳酸铜的制备实验的教学过程：通过创设碱式碳酸铜及其应用的相关情境,激发学生学习兴趣;进而围绕制备路线的确定、反应条件的控制和实验方案的设计提出5个问题,启发学生积极思考和交流讨论;在此基础上引导学生自主完成实验方案的设计;最后,提供拓展性实验资源,促进知识的迁移应用。该教学设计有利于教师从单纯注重知识传授转变为引导学生学会学习,全面提高实验素养。

Based on the disadvantages of verified and imitated teaching mode in traditional experiment teaching,guided with multi-dimensional teaching objectives and the constructive learning theory,this article explored the teaching design of preparation of cupric subcarbonate.Firstly,the teachers should try to motivate the students＇ learning interests by constructing contexts about cupic subcarbonate and its application.And then five questions aiming at the preparation route,the controlling of reaction conditions and the designing of experiment program were put forward in order to inspire the students to think deeply and discuss actively.Based on the above questions,the students were guided to complete the design of experiment program independently.Finally,some extended experimental resources were provided to promote the students＇ application of what they have learned.This teaching design is helpful to change knowledge impartment into guiding students to learn how to learn,and can enhance students＇ experiment literacy.
