摘要
染料废水处理是环境类人才必须具备的专业技能,如何提高学生们在实验学习中的主人翁意识是人才培养的关键。以BL蓝和亚甲基蓝染料水溶液为脱色对象,开放现有的实验室资源,引导学生自主查阅文献,制定方案,从而掌握废水处理的操作技能。撰写小论文记录实验过程、结果、分析原因、提出改进方案,并制作ppt交流学习心得。学生为主、老师为辅的学习过程,能充分调动学生的积极性。在此基础上提出承上启下式教育的模式,鼓励同学们课后继续参与实验将方案优化进行到底,并将最优方案应用于印染厂,实现教学成果的转化,达到素质教育的目的。
Dye wastewater treatment is a professional skill that environmental talents must have.How to improve students'sense of ownership in experimental learning is the key to talent training.Taking BL blue and methylene blue dye aqueous solutions as decolorization objects,opened existing laboratory resources,guided students to independently consult literature and formulated plans,so as to master the operation skills of wastewater treatment.Wrote a small paper to record the experimental process,results,analyze the reasons,propose improvement plans,and maked ppt to exchange learning experience.The student-centered but teacher-assisted learning process could fully mobilize the enthusiasm of the students.On this basis,a model of linking up and down education was proposed,and students were encouraged to continue to participate in experiments after class to optimize the plan to the end,and applied the optimal plan to the printing and dyeing factory,which could realize the transformation of teaching results and achieve the purpose of quality education.
