Development of the Exams Data Analysis Spreadsheet as a Tool to Help Instructors Conduct Customizable Analyses of Student ACS Exam Data
Brandriet, Alexandra; Holme, Thomas
Journal of Chemical Education, v92 n12 p2054-2061 Dec 2015
The American Chemical Society Examinations Institute (ACS-EI) has recently developed the Exams Data Analysis Spread (EDAS) as a tool to help instructors conduct customizable analyses of their student data from ACS exams. The EDAS calculations allow instructors to analyze their students' performances both at the total score and individual item levels, while also providing national normative results that can be used for comparison. Additionally, instructors can analyze results based on subsets of items of their choosing or items based on the "big ideas" from the Anchoring Concepts Content Map (ACCM). In order to evaluate the utility and usability of the EDAS for instructors, the EDAS went through trial testing with 10 chemistry instructors from across the country. The instructor feedback confirmed that the EDAS has multiple implications for the classroom and departmental assessment, but some additional revisions were needed to increase its usability. This feedback was also used to make a video user-guide that will help instructors through specific difficulties described during trial testing. Currently, an EDAS tool has been developed for the GC12F, GC10S, and GC13 exams.
