SOFTWARE SUBMISSION AND ASSESSMENT TOOL

MOTIVATION

PROCESS

The Computer Science department at RIThas used various automated systems that enable students to submit programming assignments electronically.

Currently the most popular such tool is ‘try’ developed by Professor Kenneth Reek withthe last major release coming in the early 1990’s.

The advantages to electronic submission isthe ease of file management, logging, and the value added by automated testing of the students’ code.

The Computer Science department wantsto develop a multi-platform replacementfor ‘try’ that expands its applicability, removes some of its shortcomings, and enables its integratability with other front-end tools being developed.

The solution should consist of:

1) Student software tools should allow students to submit electronic files.

2) Grader software tools that will assess and report the results of submissions.

3) Instructor software tools that will speed up the creation of new assignments.
