Iterative Evaluation of a Large-Scale, Intelligent Game for Language Learning

Educational content developers, including AIED developers, traditionally make a distinction between formative evaluation and summative evaluation of learning materials. Although the distinction is valid, it is inadequate for many AIED systems because they require multiple types of evaluation and multiple stages of evaluation. Developers of interactive intelligent learning environments must evaluate the effectiveness of the component technologies, the quality of the user interaction, and the potential of the program to achieve learning outcomes, in order to uncover problems prior to summative evaluation. Often these intermediate evaluations go unreported, so other developers cannot benefit from the lessons learned. This paper documents the iterative evaluation of the Tactical Language Training System, an interactive game for learning foreign language and culture. This project employs a highly iterative development and evaluation cycle. The courseware and software have already undergone ...
