EAC Visual Data
To assist in assessment and accreditation efforts, Grand Valley provides the EAC Visual Data tool to all faculty members, units, and programs. EAC Visual Data is the analytics and reporting portal for Blackboard's Assessment and Accreditation Solution.
Using EAC allows the leveraging of teaching and learning activities that are already happening within Blackboard Learn. Users can obtain data along with automated charts and graphs depicting student performance within a course and across a program.
How EAC can be useful for Faculty Members
- EAC can be used to review test and item reliability statistics to help improve the quality of tests and test questions.
- Identify course-level at-risk students and their areas of strengths and weaknesses.
