A usability study was conducted by the Research and Innovation Network and Assessment Solutions Design to assess the usability of a drawing response interaction type. The Partnership for Assessment of Readiness for College and Careers (PARCC) commissioned a multi-part study to determine the viability of using the drawing response interaction on the PARCC Mathematics Assessment. In the first part of the study, participants in grades 3, 9, 10, and 11 (during the 2014-2015 school year) participated. Participants completed a series of math questions on the computer or iPad that included the drawing response interaction, while observation and video recording took place. The goal of this study was to test the usability of the drawing response interaction feature and determine if and how it assists participants in problem solving. The team also wanted to gather feedback from the participants on how they would change the drawing response interaction to best help them solve problems.
