Collaborative Research: Electronic Delivery and Criterion Referencing of Assessment Materials for Chemistry

化学12该项目正在完成几项任务，将改善化学教育的评估实践。 通过美国化学学会（ACS）考试研究所存在的测试计划长期以来一直允许化学教师将学生与国家标准进行比较。 该项目通过分析ACS考试的内容来增强这一信息水平，并使用在整个本科课程中反复出现的锚定概念模板来映射主题的内容域。 然后，对齐研究使用这种分析为教师提供有关化学学生对化学键合，化学反应，分子结构和化学平衡等主题的了解的增强信息。 映射内容域和将测试问题与映射域对齐的过程都提供了重大的研究挑战，并提高了该项目的智力价值。 ACS Exams Institute每年提供超过10万名学生使用的考试，国家科学数字图书馆的化学途径ChemED DL也是该项目的合作伙伴，因此广泛的影响不仅包括ACS Exams，还包括通过ChemED DL提供的试题。另一个关键部分是将ACS考试材料移植到电子交付平台。 这一过程提供的不仅仅是增强的访问，因为电子交付考试提供的即时数据收集改善了数据分析的各个方面，包括传统的规范参考信息和标准参考信息，这些信息将测试问题与内容领域的锚定概念相关联。

Chemistry 12The project is completing several tasks that will improve assessment practices for chemistry education. Testing programs that have existed via the American Chemical Sociey (ACS) Exams Institute have long allowed chemistry instructors to compare students to national norms. This project is augmenting this level of information by also analyzing the content of ACS Exams against a mapping of the content domain of the subject using a template of anchoring concepts that recur throughout the undergraduate curriculum. Alignment research then uses this analysis to provide instructors with enhanced information about what chemistry students know about such topics as chemical bonding, chemical reactions, molecular structures and chemical equilibrium and several others. Both the process of mapping the content domain and aligning test questions to this mapped domain provide significant research challenges and advance the intellectual merit of this project. The ACS Exams Institute provides exams used by over 100,000 students annually, and the Chemistry Pathway of the National Science Digital Library, ChemED DL, is also a partner on this project, so the broad impact includes not only ACS Exams but also test questions available via ChemED DL. The other key component is the porting of ACS Exams materials to an electronic delivery platform. This process provides more than enhanced access because the instant data collection afforded by electronically delivered exams improves all facets of the data analysis, including the traditional norm-referenced information and the criterion-referenced information relating test questions to the anchoring concepts of the content domain.
