Concept map was used as a tool for research, teaching, learning and assessment. It’s applied in paper and pencil style. This style is inconvenient for modification and lack elasticity. Therefore, it’s unable to feedback to learner immediately. Through computer aided concept mapping tools can be constructed to allow students modify concept maps. This thesis uses interactive manner to create concept maps. An assessment tool for concept mapping using web-Based Kelly’s Repertory Grid Technique is devised through Kelly’s triad, learner’s construct and link names are draw out, and then proceed further analysis to create concept mapping.
