Defeating the Cheating: Redesigning a Web-based Mastery Test during Heavy Usage

• In Event: D&D - Design Cases in Evaluation and Analytics

Short Description

We present a design case on modifications to a heavily-used tutorial and test on the web: How to Recognize Plagiarism ( https://www.indiana.edu/~istd/ ). Changes were necessitated by reports of cheating, evidenced by a YouTube video with test answer keys. We designed a new test with items randomly selected from a large inventory. We further improved the test and tutorial via logs of user behaviors, observed failures, and a communication feedback loop between users and the designers.
