E-grading: electronic grading of linear equation using string similarity measure / Mohd Zairol Nazam Kamaruddin

Nowadays most applications are carried out using Information Technology (IT). Through efficient electronic networking system people are able to communicate and interact actively and efficiently in terms of time. Through IT, learning and teaching is now done rather effectively via electronically. This project discusses the effectiveness of using string similarity method in evaluating electronic answers on algebraic equations only for one variable submitted by the students. These electronic answers are then evaluated against given solutions. In order to measure the accuracy of this study, a Dice coefficient measuring approach is employed. The efficiency of this electronic grading mechanism has now preliminary tested on 4 simple algebraic equations on 150 students. Result has shown that electronic answer with average Dice coefficient >~ 0.8600 (86% matched) is accepted as correct answers. This implies that this study implicates a range of feasibility in electronic grading system.
