Evaluation of an Intelligent Web-Based Language Tutor

摘要

In this paper we present and discuss the results of the evaluation of an Intelligent Computer Assisted Language Learning system that operates over the Web. In particular, we aimed at evaluating the learning outcome and the system's ability to provide individualized support to students that leads to more effective use of the system. To achieve this, we conducted an empirical study, where we compared the intelligent system with a non-intelligent version of it. The results of the study revealed that the students of the intelligent version of the Web-based CALL had gained more knowledge of the domain and had been able to interact with the system more effectively as compared to the students that had used the non-intelligent version of the system.
