Distributed Proctoring in Distance Education Courses Ping-Herng Denny Lin, California State University Fullerton Abstract Teachers designing distance education courses may require some assignments to be graded by students. Schneier, Kelsey, and Walker developed a protocol for distributed proctoring that allows a network of graders to grade individual problems solved by a network of test takers. Anonymous MIX, public-key cryptosystems, distance education. Introduction Encouraging student interaction has been one of the pedagogical problems for distance education course designers.
Peer grading in a distance education environment can happen in several ways.
In a synchronous learning environment, there is no complete anonymity of the student grading the work of a peer. In an asynchronous learning environment, there are no facilitators to monitor the exchange of work between peers, thus peer grading becomes logistically difficult, if not impossible.
