将解决问题与理解化学概念和实验室实践相结合的能力是本科化学课程培养学生的基本技能。因此，化学课程必须提供机会来回答实际问题，这些问题需要使用实践化学家使用的解决问题的过程，包括实验设计的过程。此外，课程应该评估学生掌握这些技能的程度，并利用结果为课程开发提供信息。这篇手稿描述了一个在化学中解决实验问题的规则，旨在评估学生既能理解化学问题又能设计一个基于仪器的策略来解决它的程度。题目有效地区分了本科化学课程不同阶段学生对实习问题的回答。数据表明，学生解决问题的能力随着课程的进步而提高。
The ability to couple problem solving both to the understanding of chemical concepts and to laboratory practices is an essential skill for undergraduate chemistry programs to foster in our students. Therefore, chemistry programs must offer opportunities to answer real problems that require use of problem-solving processes used by practicing chemists, including those of experimental design. Additionally, programs should assess the extent to which these skills are mastered by students and use the results to inform curricular development. This manuscript describes a rubric for experimental problem solving in chemistry that seeks to assess the extent to which students can both understand a chemical problem and design an instrument-based strategy to address it. The rubric effectively differentiates responses to practicum questions answered by students at different stages of the undergraduate chemistry curriculum. The data show that students improve in their ability to problem solve as they progress through the...
