Abstract
A web-based online essay exam management and evaluation system were designed and implemented as a tool to help students and teachers to create and evaluate essay exams. The system allows the teacher to give textual feedback in the form of a comment by selecting parts of the essay solution which he/she assumes is not correct. The system has five main modules which are working together: System Management module (Maintenance), Instructors module, Students module, Online Exam Management module, and the Feedback module. The automatic evaluation and scoring of essay answers are performed using a pair-wise automatic essay evaluation method. The Pair-wise approach uses a reference answer (RA), provided by the teacher, and a student answer (SA) to compute the semantic similarity between them and give a score according to the weight of the question. In a survey, conducted to assess the feasibility and usability of the system, teachers responded that the system helps them to provide higher quality feedback in less time than using traditional paper-based grading. These preliminary, test runs are promising and show good indications for further improvement of the developed system.
