Object-oriented Collaborative Course Authoring Environment supported by Concept Mapping in MyEnglishTeacher

This paper presents an English upgrading course authoring environment for multiple authors collaborating via a distance education system. The course authoring follows a rigorous object-oriented structure, which allows easy search and retrieval functions for both the authoring and the learning environment counterpart. Moreover, authoring is supported by the concept mapping paradigm, where in our case the concepts are built by the keywords of the individual course building bricks (subjects), and the mapping involves manual and automatic linking of these concepts. The full system consists of both authoring and learning environment and is called MyEnglishTeacher. The focus of the paper is on the authoring environment, on the enforced object-oriented structure and on the concept mapping based course linking supporting function.
