摘　　要：基于问题导向的学习模式(PBL)是化学实验课堂中备受推崇的教学理念。本文以学生自主完成科学前沿的分子荧光实验CsPbX_(3)(X=Cl,Br,I)晶体的合成、表征及光学性质为基础,在PBL理论体系下探讨实施该实验如何影响学习者内在动机,分析增强内在动机的核心因素。结果表明,学生历经获取信息、设计实验步骤、分析实验数据、优化实验等过程的自主性学习能显著增强内在动机,促使学生发挥主观能动性,提高学习效率。Problem-based learning(PBL)is a highly regarded teaching concept in chemistry laboratory classes.This study explores how implementing the synthesis,characterization,and optical properties of CsPbX_(3)(X=Cl,Br,I)crystals within a PBL framework impacts the intrinsic motivation of learners.It analyzes the key factors that enhance intrinsic motivation.The results show that autonomous learning,in which students go through the processes of acquiring information,designing experimental steps,analyzing experimental data,and optimizing experiments,can significantly enhance intrinsic motivation.This encourages students to actively engage and improves learning efficiency.
