In this paper, we propose a scheme for evaluating learners' knowledge level on concept mapping tasks. The assessment process focuses on the propositions presented on learner's map as well as on the missing ones with respect to the propositions presented on expert map. The evaluation of learner's knowledge level depends on the weights assigned to the(More)
In this paper, we present a comprehensive framework for assessment, developed through the web-based module named PASS-Personalized ASSessment , which can be integrated in an Adaptive Educational Hypermedia System to provide personalized assessment. PASS estimates learner's performance through multiple assessment options-pre-test, self-assessment and(More)
