摘要:

为提高本科生自主学习和探究性学习的能力,指导学生开展了芳香烃体系核磁共振的理论计算研究。在问题引出、文献调研总结、体系建模及模拟、结果分析讨论等研究性教学实践中,学生不仅深入认识了取代基、分子结构、存在状态对化学位移和自旋耦合常数的影响,增进了对微观结构及宏观性质关系的认识,也提高了自主学习、知识应用和解决问题的能力。此外,这种教学活动还提升了学生深入挖掘、不断求证的探究精神和科研素养,有助于创新型人才的培养。

Abstract:

To improve the self-learning ability and inquiry-based learning skills of undergraduates, we guided the students to study the concepts and data in the literature, performed first-principles simulations, analyzed and discussed the relevant results of aromatic hydrocarbon molecules. Through this research-oriented teaching, students understood that the chemical shift is influenced by different substituent groups, chemical structures, and the states of matter, and that spin-spin coupling constants indicate chemical structures. In addition, the students gained further understanding of the relationship between the microscopic structure and macroscopic properties. Moreover, research-oriented teaching improves students' self-learning skills and ability to apply knowledge and solve problems. Furthermore, this activity type improves students' ability to explore in-depth knowledge and develop critical thinking skills, which are essential for training innovative scientists and engineers.
