识字需要阅读理解，培养阅读技能是写作技能发展的必要前提和协同推动因素。化学科学中的阅读理解不仅包括对文本的理解，还包括对数据表、方案和图表的阅读和处理。因此，化学科学写作的教育不能只注重写作，而必须着眼于培养更高水平的阅读和写作技能；此外，阅读指导应该与写作练习同时进行或先于写作练习。在此背景下，本文描述了一个计算机实验室实验，该实验培养了学生阅读光谱的能力。计算机实验室实验培养学生的Excel技能，具体目标是教他们光谱中单个跃迁如何重叠。讨论了定性分解和自动求解器扩展方法。定性分解最适合培养学生对重叠跃迁和光谱的理解，并提高他们的概念知识。学习使用Solver是一项有价值的附加技能，但是自动化的过程不能替代由定性分解提供的学习经验。
Literacy requires reading comprehension, and fostering reading skills is an essential prerequisite to and a synergistic enabler of the development of writing skills. Reading comprehension in the chemical sciences not only consists of the understanding of text but also includes the reading and processing of data tables, schemes, and graphs. Thus, education in scientific writing in chemistry cannot focus on writing alone, but such efforts must aim both at the development of higher level skills in reading and writing; moreover, the reading instruction ought to occur concurrently with or precede the writing exercise. In this context, a computer laboratory experiment is described which develops students' ability to read spectra. The computer laboratory experiment cultivates students' Excel skills with the specific objective of teaching them how individual transitions overlap in spectra. Qualitative decomposition and an automated Solver extension method are discussed. Qualitative decomposition is best suited to develop students' understanding of overlapping transitions and spectra and to advance their conceptual knowledge. Learning to use Solver is a valuable additional skill, but the automated process is no substitute for the learning experience provided by the qualitative decomposition.
