The paper deals with an e-learning system for language learning. An e-learning system is viewed as an expert system working under uncertainty. Input information is acquired on the basis of didactic tests assessing student?s language level, questionnaires gathering information about student?s learning style, study prerequisites, etc., which is stored into a database and used for adaptation of content and learning style (topics, composition and form of the proposed study materials, etc.). Adaptation and automated passing are achieved by dividing the process of studying into four basic processes - (M1) acquisition, completion and evaluation of the input information; (M2) definition of language learning objectives and admissible solutions; (M3) modelling the progress of proposed solutions; (M4) approving one of the proposed solution as the best variant to achieve the learning objectives. The decision-making process making the choice of further progress is dealt with by an expert system using IF-THE.
