Molecular biology supported by an intelligent tutoring system

Background and purpose: The purpose of these investigations was to show how molecular biology was supported by an intelligent tutoring system (ITS). Its was made for students education at University to give explanation of transmission mechanism and expression of genetic information which ultimately governs cell structure and function. Material and methods: In this work we describe the application of the intelligent hypermedial authoring shell Tutor Expert System (TEx Sys) in developing knowledge base on fundamental principles of molecular biology. TEx-Sys is used in lecturing students of the biology and chemistry study group within the course of lectures called Computer Aided instruction. Conclusion and future works: intelligent tutoring systems use the techniques discovered in artificial intelligence research to aid in the leaching and learning of some subject ma tier or skill. The results of such application have shown that after first difficulties in acquiring formalized representation of knowledge, students gladly accept this way of learning and testing their knowledge. According to them, the hypermedia characteristics of TEx-Sys are particularly contributing to easier mastering of the domain knowledge. Results: The results are therefore rather encouraging and initiate the gradual widening of the existing knowledge base by evermore complex knowledge structures Besides, we are facing the necessity of enhancing the range of learning up to the level of the entire Cell Biology subject matter through the application of a sophisticated courseware program module. The possibilities of such application are still open, considering that we have only started testing the efficiency of its interrelation with World Wide Web services.
