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

该项目正在完成几项任务，这些任务将改进化学教育的评估实践。长期以来，通过美国化学学会(ACS)考试研究所存在的测试计划一直允许化学教师将学生与国家常模进行比较。这个项目通过使用在整个本科课程中反复出现的锚定概念的模板，对照学科内容领域的映射来分析ACS考试的内容，从而增加了这一级别的信息。比对研究然后利用这一分析为教师提供关于化学学生关于化学键、化学反应、分子结构和化学平衡等主题的增强信息。映射内容域和将测试题与该映射的域对齐的过程都提供了重大的研究挑战，并促进了该项目的智力优势。美国国家科学图书馆考试研究所每年提供超过100,000名学生使用的考试，国家科学数字图书馆化学路径也是该项目的合作伙伴，因此其广泛的影响不仅包括ACS考试，还包括通过中国数字图书馆提供的测试题。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，因为电子考试提供的即时数据收集改进了数据分析的所有方面，包括将试题与内容领域的锚定概念联系起来的传统常模参考信息和标准参考信息。

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.
