W20: Comparing Personally Written Test Items with ACS Exams Items

Log in to save this to your schedule and see who's attending!

This workshop is designed to allow participants view the developing interface that will allow instructors to compare student perfomance on their own test items with national samples of student perfomances on ACS test items on the same topic. The comparison is based on the Anchoring Concepts Content Map (ACCM) for General Chemistry (JCE, 89, 721, 2012). 2000 test items from the past 20 years of general chemistry exams from ACS Exams have been aligned to the ACCM. The interface will help identify probably maps for an entered test item, allow the user to confirm a particular content area, and then provide comparison information about student performance. Feedback from participants will be used to provide features that will enhance the utility of this tool as it is developed. (Note this project is funded by the National Science Foundation.)
