Abstract

Abstract: Adaptive E-Learning systems are needed to efficiently support lifelong learning activities. To check goal attainment, learners need to take tests or assessment activities. Large efficiency gains may be made if the assessment and associated grading or evaluation process could be supported with adaptive systems sensitive to user parameters. Hand made tests are a timeconsuming and tiresome task. If the tests are hand scored there is the inevitability of either interrupting the learning whilst the assessment outcome is pending, or the danger of proceeding with the attempt at learning possibly unsuitable content. As a contribution to solving the problem stated so far we have designed the E-TESTER. In this paper we describe the implementation solution and its integration into the AdeLE system, point out the potential of the E-TESTER by an application example, and discuss the experiences of the prototype implementation. Keywords: adaptive E-Learning, knowledge acquisition, auto-generated questions, automatic answer assessment, AdeLE, E-TESTER, LMS, Learning Management Systems. Background E-Learning is a promising and widespread solution in a variety of application scenarios. According to the 2003 IDC study (IDC 2003), some 934 million USD was invested in E-Learning worldwide in that year.
