摘 要:将教材酚醛树脂制备实验的改进作为项目基础,以制备水溶性酚醛树脂胶为项目主题,通过“分析教材实验装置的不足并设计新的实验装置”“探究反应物药品用量对产物的影响”“探索催化剂的选用对产物的影响”“探究反应时间对于水溶性酚醛树脂制备的影响”“酚醛树脂胶的制备与项目汇报总结”等5个子任务,使学生深刻理解有机化学聚合反应与高分子材料的相关内容,促进学科知识与工业生产等生活实际相联系。在项目实施过程中,学生通过小组合作的方式,挖掘并整合关键信息,进行证据推理与实验探究,培养学生的“宏观辨识与微观探析”“证据推理与模型认知”“科学探究与创新意识”等3方面的化学学科核心素养。The improvement of the preparation experiment of phenolic resin in the textbook was taken as the project basis,and the preparation of water-soluble phenolic resin glue was taken as the project theme.Through the five sub-tasks of“analyzing the shortcomings of the experimental device of the textbook and designing a new experimental device”“exploring the influence of the usage amounts of the reactants on the product”“exploring the influence of catalysts selection on the products”“exploring the influence of reaction time on the preparation of water-soluble phenolic resin”“preparation of phenolic resin glue and summary of project report”,students could deeply understand the related contents of organic chemical polymerization reaction and polymer materials and promote the connection between subject knowledge and real life such as industrial production.In the process of project implementation,students excavated and integrated key information through group cooperation,carried out evidence reasoning and experimental inquiry,and cultivated core literacy of chemistry in three aspects:macro identification and micro analysis,evidence reasoning and model cognition,scientific inquiry and innovation consciousness.
