基于PBL模式的化学实验设计与实施——以光催化降解染料脱色实验为例

Design and Implemention of Experiment of Photocatalytic Degradation of Dye Based on PBL

以染料废水的降解脱色实验为例，探讨了PBL模式在化学实验教学中的应用，提出了基于PBL模式的化学实验教学运行程序及教学评价。在实验教学中，基于PBL的模式，以解决问题为任务驱动，发挥问题对学习过程的指导作用，鼓励学生积极参与教学过程，调动了学生学习的主动性和积极性，提高了学生掌握知识并应用于实践的能力，培养了学生的创造精神和创新能力。

Taking the experiment of decolorization and degradation of dye wastewater as an example, this paper discussed the application of PBL mode in chemical experiment teaching and put forward the operation procedures and teaching evaluation. The experiment teaching took problem solving as task driven based on PBL mode, played the guiding role of problems in the learning process, encouraged students to actively participate in the teaching process. These methods could mobilized students＇ learning initiative and enthusiasm, improved students＇ ability to master the knowledge and practical ability, cultivated students＇ creative spirit and innovative ability.
