将过程导向探究学习(POGIL)的原理应用于氢原子发射光谱的分析。在三个学习周期的过程中,学生构建氢原子的能级图,并使用他们对Balmer系列的测量加上Lyman和Paschen系列的发射线的附加信息来分配量子数。作为POGIL物理化学实验室项目的一部分,这种对氢发射光谱的引导查询方法已经在几个机构用各种光谱仪器进行了测试。导致量子数分配的分析需要简单而廉价的材料:尺子、彩色笔和长条纸。
The principles of process-oriented guided inquiry learning (POGIL) are applied to the analysis of the emission spectrum of atomic hydrogen. Over the course of three learning cycles, students construct the hydrogen atom’s energy level diagram and assign quantum numbers using their measurements of the Balmer series plus additional information on the emission lines in the Lyman and Paschen series. This guided inquiry approach to the hydrogen emission spectrum, which was developed as part of the POGIL Physical Chemistry Laboratory Project, has been tested at several institutions with a variety of spectroscopic instruments. The analysis leading to the assignment of quantum numbers requires simple and inexpensive supplies: rulers, colored pens, and long strips of paper.
