This paper reports on the development of a web-based learning system called “Information Theory Hands-on Center” for combined learning of information theory. While general textbooks and materials allow students to understand individual concepts, it has been difficult to grasp the overall communication flow by combining these concepts. Our system provides an interactive learning environment covering fundamental concepts such as information content and entropy, source coding with Huffman codes, and channel coding with Hamming codes. Students can experience not only individual theories and algorithms, but also the complete process where a sender transmits messages through noisy channels using Huffman and Hamming codes, and a receiver decodes messages while correcting errors. In an evaluation experiment conducted with the cooperation of undergraduate students, no significant difference was found in test scores before and after system use. However, the five-point scale questionnaire showed an average rating of 4.48 for “promotion of understanding” and 4.28 for “content richness.”
