A Knowledge-Based Approach of Modeling an Internet-Based Intelligent Learning Environment for Comprehending Common Fraction Operations

The goal of the study in this chapter is to support learners to engage in the active learning of common fraction operations from the constructivists’ perspective. An Internet-based Fraction-learning Intelligent Learning Environment (IFILE) is designed under the knowledge-based approach to model the learning process of the target topic. It is intended to optimize the interaction opportunity of learners by providing pedagogical tools and intelligent features. The two pedagogical tools provided are graphical support and electronic blank sheet. The intelligent feature discussed in this chapter is the Next Step Support for helping learners to break the impasse in fraction operations. The key activity of the construction of the Next Step Support of this knowledge-based application is designing rules as embedded units to sense and react to all facets of the fraction evaluation process. This chapter discusses further how the IFILE is designed for developing learning properties from the constructivists’ standpoint.
