Abstract
Web-based learning should move away from static transmission of instruction to dynamic pages
for effective interactive learning. Furthermore, automated assessment of learning should move
beyond rigid quizzes or multiple-choice questions.
This study describes the design, development, implementation, testing and evaluation of two
prototypes of an electronic assessment tool to enhance the effectiveness of automated
assessment. The tool was developed in the context of a distance-learning organisation and
was built according to a development research model entailing a cyclic design-intervention-outcomes
process.
The first variant, E-Grader, was developed to test an algorithm for assigning marks to open-ended
textual responses. The second variant, Web-Grader, was an interactive web-based
extension of E-Grader. It provided immediate interactive support to students as they responded
textually to content-based questions.
This multi-disciplinary study incorporates principles and techniques from software engineering,
formal computer science, database development and instructional design in the quest towards
electronic assessment of web-based textual inputs.
