摘要:

主要介绍厦门大学专门为“化学拔尖计划”学生个性化培养“量身定制”的“trans/cis-[Co(en)2Cl2]Cl配合物的制备及其光谱鉴定”实验教学实施结果及探讨。以“trans/cis-[Co(en)2Cl2]Cl配合物的制备及其光谱鉴定”实验为载体,围绕着合成两大目标“质”和“量”,也就是以如何才能得到又“好”又“多”的trans/cis-[Co(en)2Cl2]Cl配合物等问题为导向,以所展示的详细直观的制备流程和紫外-可见吸收光谱图为基础,以实验结果为依据,以设问、探讨的方式对合成过程、条件等进行仔细分析和深刻反思、判断,以展示实验教学过程中如何有效地培养学生的批判性思维。

Abstract:

This article mainly introduces the laboratory teaching results and discussions of "preparation and spectral identification of trans/cis-[Co(en)2Cl2]Cl", which is specially designed for the top talented chemistry-majored students in Xiamen University. Focusing on the two synthetic targets of "quality" and "quantity", i.e., how to get "pure" and "multiple" trans/cis-[Co(en)2Cl2]Cl complexes, the synthesis process and conditions were analyzed, reflected, and judged by questions and discussions based on the detailed and intuitive preparation process and UV-Visible absorption spectrum. Through this practice, we want to show how to effectively cultivate students' critical thinking in the laboratory teaching process.
