摘要:Guide on the Side (GotS) is an award-winning application that makes developing interactive, online tutorials simple [ 1 – 3 ]. As the “Guide on the Side” name suggests, each GotS tutorial has an instruction panel—which may contain text, pictures, links, and/or interactive questions—on one side of the browser window and displays the online resource that is the focus of the tutorial on the other side. GotS is open source software that is available without charge from the University of Arizona. Even if you are not sure that your information technology (IT) department will be willing to install GotS, you may want to request a free demo account on the University of Arizona server and give GotS a try [ 3 ]. As the Association of College & Research Libraries (ACRL) 2013 Instructional Services Innovation Award committee cochairs have said, the software “allows librarians to easily create tutorials that are both engaging to students and pedagogically sound. GotS serves as a model of the future of library instruction” [ 1 ].
