Collaborative Research: Adapting IMMEX to provide problem solving assessment materials from the ACS Exams Institute

该项目是美国化学学会（ACS）考试研究所、克莱姆森大学和IMMEX项目之间的合作，旨在通过采用IMMEX技术为大学化学前两年开发替代评估工具。 目标和目的如下。 1. IMMEX案例的内容重点是化学结构和功能，正在整理和适应总结性解决问题的评估，并根据需要设计更多的案例，以补充现有的案例与结构和功能的内容基础。 2. IMMEX内的个别情况下的动态问题解决行为的分析正在进行调整，以允许跨几个案件的结构和功能的认知域的测量，和认知措施。 3. 内部的可靠性和有效性的结构和功能的问题解决的比较正在建立在多个IMMEX的情况下，使用的措施，包括项目反应理论分析，以及性能和神经网络和隐马尔可夫模型的进展措施的组合。这些措施包括测量rubrics之间的transitionsdynamic问题解决状态的学生，以确定收益的使用成功的问题解决策略的学生在大学化学的头两年。 4. 正在ACS考试所办公室建立一个远程IMMEX服务器，以提高向越来越多的全国学生提供IMMEX案例的能力。 5. 目前正在设计一个报告系统，该系统将由考试研究所发布，以便为教师提供参与该项目的学生在成功解决问题的策略方面的收益报告。一系列的问题，结构和功能之间的关系的基础上，正在开发和由此产生的评估数据被用来开发预测模型，为个别学生的问题解决者。由此产生的学生解决问题的行为数据库也为化学教育工作者提供了一个资源。更广泛的影响这个项目涉及到新的评估技术扩展到全国人口。由此产生的可靠的，规范的评估，从一个值得信赖的来源（美国考试协会），侧重于解决问题的更深层次的方面将提供给更广泛的受众。这些工具的提供预计将促进强调深度学习和解决问题的改革课程的推广。

This project is a collaboration between the American Chemical Society (ACS) Examinations Institute, Clemson University and the IMMEX project, to develop an alternate assessment instrument for the first two years of college chemistry by adapting IMMEX technology. The goals and objectives consist of the following. 1. IMMEX cases with content emphasis on chemical structure and function are being collated and adapted for summative problem solving assessment, and additional cases are being devised as needed to complement current cases with structure and function content bases. 2. Analysis of dynamic problem solving behavior for individual cases within IMMEX is being adapted to allow the measurement of the structure and function cognitive domain across several cases, and cognitive measures. 3. The internal reliability and validity of the comparison of structure and function problem solving is being established across multiple IMMEX cases using a combination of measures including Item Response Theory analysis as well as performance and progress measures derived by neural network and hidden Markov modeling. These include measurement rubrics for transitionsbetween dynamic problem solving states for students to determine gains in the useof successful problem solving strategies for students in the first two years of college chemistry. 4. A remote IMMEX server is being established at the offices of the ACS Examinations Institute to enhance the ability to provide IMMEX cases to a growing national pool of students. 5. A reporting system is being devised that will be published from the Exams Institute to provide instructors with reports of the gains in successful problem solving strategies for their students participating in this project.Intellectual meritThis project is grounded in the prior research on assessment of problem solving usingIMMEX technologies. A range of problems, based on the relationship between structureand function, is being developed and the resulting assessment data are being used to develop predictive models for individual student problem solvers. The resultant database of student problem solving behavior also provides a resource for chemical educators.Broader ImpactThis project involves the extension of new assessment technologies to a nationalpopulation. The resulting reliable, normed assessments from a trusted source (the ACSExaminations Institute) that focus on deeper aspects of problem solving will be availableto a broader audience. The availability of these instruments is expected to facilitate the spread of reformed curricula that emphasize deep learning and problem solving.
