基于网络的问题教学模式在材料化学选修课教学实践中的应用

Application of Problem-based Teaching Mode in Materials Chemistry based on Network

运用基于网络的问题教学模式在材料化学课程教学中进行了教学实践探索。该教学模式旨在摒弃单一的“满堂灌”课堂授课形式，采用以学生自学、讨论为主，教师引导、点评为辅的方式，并且将网络化手段引入教学过程中。具体过程是：教师设置问题，学生则根据问题查阅相关文献资料并展开讨论，进而对讨论结果进行归纳、汇总；而教师根据汇总的结果有针对性地进行点评和指导。实施结果表明，该授课形式有利于学生自主学习、提高学生解决问题的能力，是建立多元化授课形式的教学体系的有益探索。

Problem-based teaching mode based on network has been applied in materials chemistry teaching. In the new teaching mode, students learned autonomously and teachers gave supplementary guidance by means of network. In the specific process, teachers set questions; students consulted relevant documents, discussed according to the given questions, and then summed up the discussed results; in the end, teachers gave corresponding comments and guidance in view of the summarized results. Practical results indicated that the new teaching mode was in favor of cultivation of autonomous learning and abilities of problem solving for students, which was useful for estab- lishing diversified teaching forms.
