However, conducting successful peer assessment remains challenging as peer graders often do not have sufficient guidance to make fair assessment and to provide useful feedback. In this thesis, we explore the potential of using a chatbot to facilitate the execution of peer assessment. We conducted two studies in two university courses. The first one was a within- subject study, which focused on understanding the effect of chatbot use for peer assessment over time. The second was a between-subject study, which addressed the differences between providing guidance by a chatbot and giving suggestions through a regular form. Our results show that, using a chatbot for several times, students improved the performance of conducting peer assessment by providing more accurate scores that were closer to the TAs’ scores. Also, when the chatbot provided guidance, high-performing peer graders were more likely to give positive comments with constructive suggestions than low-performing peer graders did. Our results provide insights into designing interaction technologies to improve both the quality of peer assessment and students’ learning.","Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2022-05-01","The student, Dennis Wang, accepted the attached license on 2020-05-14 at 15:34.","The student, Dennis Wang, submitted this Thesis for approval on 2020-05-14 at 15:38.","This Thesis was approved for publication on 2020-05-15 at 08:03.","Embargo set by: Seth Robbins for item 115968 Lift date: 2022-08-27T00:51:40Z Reason: Author requested closed access (OA after 2yrs) in Vireo ETD system","Author requested closed access (OA after 2yrs) in Vireo ETD system","Limited"]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Supporting students’ peer assessment using chatbots"]}]}],"canonical_facts":{"dc:contributor":["Huang, Yun"],"dc:creator":["Wang, Dennis"],"dc:date":["2020-08-27T00:51:34Z","2022-08-27T00:51:40Z","2020-05-15","2020-05"],"dc:description":["DSpace SAF Submission Ingestion Package generated from Vireo submission #15397 on 2020-08-25 at 17:44:28","Made available in DSpace on 2020-08-27T00:51:34Z (GMT).
