07/21/97 MOSS Current Problem Believe it or not, there are some students at SIU-E that do not write their own code for programming assignments. Instructors need a way to check multiple sections of programming assignments for similarity. Doing this by hand takes way too long. There exists an application hosted by U.C. at Berkeley called MOSS to compare programs, but the process of submitting them is currently very inconvenient.

07/21/97 MOSS Current MOSS Problems Command line Perl script for UNIX. No GUI or MOSS I/O automation. Not integrated with student drop boxes. 2 week lifetime MOSS reports.

07/21/97 MOSS The Solution The Code Cop System Easy to use GUI Automated MOSS I/O Integrated with current student drop boxes Integrated with instructor class database Web hosted functionality Local archive of MOSS reports

07/21/97 MOSS Sample Scenario: Scenario nameInstructorAddsAssignment Participating Actor InstancesTerry: Teacher Flow of events1. Terry assigned a program to her third section of cs150 for the spring semester of 2001 that is due in one week. She activates the “Add Assignment” function of the Code Cop system. 2. Terry enters the assignment name and the due date. 3. Terry receives a message that acknowledges that the assignment has been successfully added.

07/21/97 MOSS Sample Scenario: Scenario nameInstructorAddsInstructor Participating Actor InstancesTerry, Joe: Teacher Flow of events1. Terry is responsible for the new instructor, Joe. She activates the “Add Instructor” function of the Code Cop system. 2. Terry enters “Joe” as the instructor’s name. 3. Terry receives a message that acknowledges that Joe has been successfully added as an instructor.
