Abstract

Technology affords the ability to make new measurements that are not available with traditional paper-and-pencil assessments. Many of these measurements can be achieved because of new interactions made possible between test takers and the technology used in the assessment. Because the goal of any such assessment tool is to measure content, it is imperative that these new interactions do not introduce extraneous factors by which measurement errors can occur. Usability testing can be employed to prevent measurement errors from occurring by ensuring that users understand how to effectively use new technologies. In this chapter, a usability study completed for a computer-based chemistry assessment system that measures how students use multiple external representations is discussed to understand how a person's perceived usability of the system can be measured while accounting for the possible influence of their assessment outcomes.
