Paper Abstract:	Code Tutor is a Web-based intelligent tutoring system that facilitates learning of radio communications to the students of a telecommunications college. There exist a number of other Web-based intelligent tutoring systems, but their descriptions in the open literature seldom expose important architectural and design details for the sake of showing interesting aspects of cognitive modeling, discussing the systems' usability, and analyzing their learning effects. The paper presents explicitly Code Tutor's architecture, design, and implementation, as well as some details of both students' and teachers' sessions with the system. Code Tutor was built using modern intelligent and Web-related technologies, such as ontologies, Java-based expert system tools, Java servlets, Apache HTTP Server and JServ package, and XML. The system is actively used in practice, and experience shows that students are happy using it as a support for learning different topics in the domain of radio communications. The system is simple to use and update, and exhibits intelligence in organizing and presenting the learning material, assessing the students' knowledge, and giving them recommendations on further learning steps.
