| 以项目为载体,将知识模块化、问题化,推动基础知识、实践技能与创新能力在递进式项目式课程群中的深度耦合,是持续培养本科生创新能力的重要途径。实验教学是项目式教学的关键环节,结合“新型二次电池项目”课程群设计了综合实验教学项目。以钾离子电池负极材料为研究中心,以阴离子掺杂诱导的异质结构对储钾性能的影响为切入点,设计了集“材料制备、结构表征、性能评价”于一体的综合性实验。学生通过V<sub>3</sub>S<sub>4-x</sub>Se<sub>x</sub>异质结构的合成、表征及电化学测试,探究阴离子掺杂对材料结构与钾离子电池电化学性能的影响规律。该项目的实施拟推动实验教学由传统的“验证式”向“探究式”转变,锻炼学生实验设计与数据分析的能力,为项目式教学背景下化学与新能源材料类实验教学提供案例。 |
| 英文摘要: |
| Using projects as carriers, modularizing and problematizing knowledge, and promoting the deep coupling of foundational knowledge, practical skills, and innovative capabilities within a progressive project-based curriculum group, represent an important pathway for continuously cultivating students" innovative abilities. Experimental teaching plays a key role in project-based teaching. A comprehensive experimental has been designed for the “new rechargeable battery project” curriculum group. Focusing on anode materials for potassium-ion batteries, the experiment mainly studies the influence of heterostructures induced by anion doping on potassium storage performance. As a result, a comprehensive experiment integrating "material synthesis, structural characterization, performance evaluation is established. Through the synthesis, characterization, and electrochemical testing of V<sub>3</sub>S<sub>4-x</sub>Se<sub>x</sub> heterostructures, students investigate the effects of anion doping on material structure and the electrochemical performance of potassium-ion batteries. The implementation of this experiment aims to transform experimental teaching from a traditional "verification-oriented" approach to an "inquiry-oriented" one, to train students" abilities in experimental design and data analysis. This provides a case study for chemistry and new energy materials-based experiment teaching in the context of project-based curriculum teaching. |
