2016_09_GIFT Cloud: Improving Usability of Adaptive Tutor Authoring Tools within a Web-based Application (HFES 2016)
GIFT Cloud is the recently released web-based application version of GIFT, an open-source computer based tutoring architecture that supports authoring, deployment, and evaluation of intelligent tutoring system technologies. This paper presents the GIFT Cloud Authoring Tools, through the lens of usability. Each major element within the authoring tools is described, along with usability design considerations that were made in order to reduce occurrence of error, to organize information, and to support end-user goals. The initial release of GIFT Cloud supports an iterative design approach, informed by user data and feedback, with an overall goal of making tutor authoring practical for subject matter experts without computer programming or instructional design knowledge. As such, lessons learned from this release, as well as plans for future research and usability improvements, are discussed.
