摘　　要：以建构主义“支架式”教学理论为指导,以能源化工领域清洁能源生物乙醇的高效生产技术为切入点,设计了“生物乙醇发酵生产”的探究性实验项目。首先,针对酵母菌株代谢类型和发酵过程影响因素(发酵时间、发酵温度、发酵pH等),设计了单因素分析及双因素(温度和pH)优化两个层次的“支架式”实验项目。通过创设“酵母历险记”情景,引导学生自主学习和小组成员协作会话,设计个性化的探究性实验方案,加强组内分工协作,搭建实验平台,开展生物乙醇发酵生产影响因素探究的实验,并对实验结果进行深度分析。在此基础上,教师深入思考教学评价反馈,拓展第二课堂,持续提升学生的创新能力。该探究性实验有助于学生搭建“生物-能源-化工”的跨学科知识体系,提升学生的综合实践能力、团队合作能力、创新能力和工程思维。Based on the urgent demand for efficient production technology of clean energy bioethanol in the field of Energy and Chemical Engineering,an exploratory experiment project of“bioethanol fermentation production”was designed under the guidance of constructivism“scaffolding”teaching theory.Firstly,a twolevel“scaffolding”experiment project was designed to optimize the metabolic type of yeast strains and the factors affecting the fermentation process(fermentation time,temperature,and pH)using the single factor design and double factor(temperature and p H)design.Through the creation of the“Yeast Adventure”scenario,students were guided to study independently and cooperate with group members to design the experiment schemes,preliminarily completing the meaning construction.During the implementation of the project,students built an experimental platform,carried out research experiments on the influence of different conditions on the ethanol fermentation,and conducted in-depth analysis of the experimental results.Teachers thought deeply about the evaluation and feedback of the experiment,extended the experiment,carried out“the second class”to improve the students'innovation ability.This exploratory experiment helps students build an interdisciplinary knowledge system of“Biology-Energy-Chemical Engineering”,improves students'comprehensive practical ability and engineering thinking,teamwork ability,innovation ability and engineering thinking.
