What is the ABCD Cards app?

The ABCD Cards app can be used in an educational setting as a polling tool and alternate to conventional paper ABCD cards. The simple interface allows for answers to be communicated visually to the instructor quickly and easily. For additional interactive ideas for teaching, see the WWU Teaching Handbook.


The 2023 version of the ABCD Cards app allows for the ability to rotate the display, updated image-based displays to button displays, increased info and ? button sizes, and changed the blue color option to a more accessible contrast level according to WCAG guidelines. Also introduced a web-based version for a non-app choice.


The ABCD Cards app was created by the Center for Instructional Innovation & Assessment at Western Washington University.

Project Lead: Justina Brown
