These video comments can resolve many points of confusion for learners. However, finding relevant content in a separated discussion forum is challenging and disruptive to learning flow. This paper introduces Adjacent Display of Relevant Discussion (ADRD): it displays threaded comments in a panel adjacent to the video and dynamically updates the content of the panel based on the time of the video. In a between-subjects lab study (n=20), ADRD helped participants resolve confusion points, skim and read comments, and encouraged video interaction.<\/jats:p>","DOI":"10.1145\/3449217","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T17:49:24Z","timestamp":1619113764000},"page":"1-11","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Adjacent Display of Relevant Discussion Helps Resolve Confusion"],"prefix":"10.1145","volume":"5","author":[{"given":"Matin","family":"Yarmand","sequence":"first","affiliation":[{"name":"University of California, San Diego, La Jolla, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Srishti","family":"Palani","sequence":"additional","affiliation":[{"name":"University of California, San Diego, La Jolla, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott","family":"Klemmer","sequence":"additional","affiliation":[{"name":"University of California, San Diego, La Jolla, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"Akshay Agrawal Jagadish Venkatraman Shane Leonard and Andreas Paepcke. 2015.
