The ABCD Cards app can be used in an educational setting as a polling/Q&A tool and as an alternate to the conventional paper ABCD card method. The simple interface provides students with a paper-free way to easily display an answer to an instructor's question and for the instructor to quickly look across the room for the general consensus of answers. Clicking on a letter/color fills the screen with that letter/color; clicking again brings you back to the main screen. ABCD Cards was created by the Center for Instructional Innovation & Assessment at Western Washington University (WWU). Updated 2023.
