化学专业的理论化学课程

Theoretical Chemistry Course for Students in Chemistry

Qingyong Meng

摘要:

本文对理论化学课程的教学内容进行了改革,建立了从微观到宏观的理论内容体系,全面地向化学专业本科生介绍化学反应理论。为了在普通理化课程的基础上开发此类TC课程,我们着眼于物理与化学课程之间的最后一公里问题,对化学专业本科生的批判性思维进行训练。为了清楚地表明这一点,聚合物分子动力学的简化方案作为一个例子进行了讨论,它显示了不同的理论内容,在高分子化学。此外,我们提出了一系列的经验和依赖的措施,可以提供有关学生的知识和理解水平的信息。本次评估测验旨在测试学生对TC基本概念和应用的了解,例如动力学、统计系综、动力学等。从36名学生的实际教学中发现,这些学生的表现比目前的TC内容有显着提高。对每个问题的进一步分析表明,大约三分之二的学生学习了新知识。虽然目前的TC课程可能会被认为是一定程度的难度,化学家,这些分析表明,学生可以有效地接受这些复杂的概念。

英文摘要:

In this work, the teaching content of a theoretical-chemistry (TC) course is reformed, establishing a theoretical contents from micro- to macro-system, and comprehensively introducing the theory of chemical reaction to undergraduate students in chemistry. In order to develop such TC course based on the general physical-chemistry course, we focus on the last-mile problem between the physics and chemistry courses to train the critical thinking of undergraduate students in chemistry. To clearly show this, a reduction scheme of polymer molecular dynamics was discussed as an example, which shows a different theoretical content in polymer chemistry. Moreover, we propose a series of experiences and dependent measures that can provide information regarding students' levels of knowledge and understanding. This assessment quiz was designed to test students on the fundamental concepts and applications of TC, such as dynamics, statistical ensemble, kinetics, and so on. From the actual teaching for 36 students, it was found that these students performed significantly improvement from the present TC content. Further analysis of each individual question revealed that approximately two-third of the students learn new knowledge. Although the present TC course might be considered to be a certain degree of difficulty for chemists, these analyses show that students can effectively accept these complicated concepts.
