Application of Learning and Testing Intelligent System with Cognitive Component Based on Mixed Diagnostics Tests

Relevance of computer based learning and testing of students is discussed. Learning and testing intelligent system (LTIS) is proposed for learning, testing, learning results and dynamics assessment. LTIS is aimed at professional and personal skills and abilities estimation, and also for designing learning trajectory of courses. A new assessment approach called mixed diagnostic tests (MDT) for LTIS construction is discussed. Analysis of the effective MDT and their implementation are proposed. The cognitive component based on 3-simplex and 2-simplex prism is suggested. MDT reduces both time and cost expenses for organization and control of the educational process. Since MDT may replace consultant function of teacher, the proposed approach is promising in the blended learning. The decision-making results are justified via cognitive component.
