Educational Thesaurus for Learning Electronics

The paper focuses on the information system the core component of which is an educational thesaurus. The learning management system is proposed based on the appropriate educational thesauri. Also, effective procedures of the thesauri filling and ranking are discussed. An analysis carried by the authors revealed the drawbacks of the conventional learning tools and became the initial point for the development of the new knowledge resource. To meet learners’ expectations, the principles of the educational thesaurus design are proposed in the paper. Following these principles, effective procedures and algorithms of data filling and ranking were developed that prevent conceptual recursion and repetition, restrict the number of predetermined concepts in the articles, and promote concept redefining. Cited examples and implementation results confirm the thesaurus suitability for learning management. As opposed to the traditional environment, the system allows finding the starting position at which concepts may be introduced. The thesaurus simplifies conceptual understanding both for students and teachers. Key-Words: electronics, learning, thesaurus, object-oriented approach
