摘要
围绕太阳能光-热-电三场协同处理甲醛废水的研究,设计了一套综合实验教学方案,旨在提升学生专业素养与科研能力。实验以“问题导向”和“科教融合”为核心,进行系统化的教学设计,内容涵盖基础引领、实操展示、结果分析和自主探索4个环节。两轮教学实践表明,通过优化材料制备参数、剖析降解机理等训练,学生的实验操作技能与团队协作能力得到显著提升。问卷调查结果显示,93%的学生认为“该实验激发了科研兴趣”、85%的学生表示“加深了对绿色化学理念的理解”。该方案验证了其在培养学生跨学科能力和创新意识方面的有效性,为环境类实验教学改革提供了可复制的范例。
This study designs a comprehensive experimental teaching scheme for formaldehyde wastewater treatment based on the solar photo-thermo-electro triple-field coupling process,aiming to enhance students’professional competence and scientific research capabilities.Focusing on the principles of“problem-oriented learning”and“integration of scientific research and education”,the experiment employs a systematic instructional design that integrates theoretical guidance,practical demonstration,result analysis and self-directed exploration.Two rounds of teaching practice demonstrated that training in optimizing material preparation parameters and analyzing degradation mechanisms significantly improved students’experimental skills and teamwork abilities.Questionnaire results revealed that 93%of the students reported that“the experiment stimulated their research interest”,while 85%stated it“deepened their understanding of green chemistry principles”.This validates the feasibility of the experiment in cultivating students’interdisciplinary abilities and innovative thinking.The scheme provides a replicable model for reforming environmental engineering experimental teaching.
