摘要
综合性、设计性实验能更好地激发学生的学习兴趣和培养学生的科研思维。为促进新疆大学“双一流”专业教学改革和实验室建设,培养学生成为应用型创新人才,该文设计了一个基于电位滴定测定植物叶片中甲酸脱氢酶活性的综合性实验教学案例,并已成功应用于化学专业本科生实验教学中。实践结果表明,该案例紧密衔接本科生基础课实验教学,强调“问题引出”“解决思路”和“实践验证”的流程完整性及连贯性,不但设计性和能动性强,且兼顾综合性与实用性,能够有效地启发和培养学生的创新思维和实践能力,适用于化学、环境、生物等相关专业的高年级本科生的实验教学。
Comprehensive and designed experiments can better stimulate students’interest in learning and cultivate their scientific research thinking.To promote the teaching reform and laboratory construction of Double First-Class major in Xinjiang University and train students to become application-oriented innovative talents,a comprehensive experimental teaching case was designed based on the determination of the activity of formate dehydrogenase in plant leaves by potentiometric titration,which has been successfully applied to the experimental teaching of undergraduate students in chemical specialty.The teaching practice showed that the case was closely connected with the experimental teaching of undergraduate basic course,emphasizing the process integrity and coherence of problem elicitation,solution thinking and practice-based verification.The design was not only creative and initiative,but also comprehensive and practical.It could effectively inspire and cultivate students’innovative thinking and practical ability,suitable for chemical,environmental,biological and other related professional senior undergraduate experimental teaching.
