In this article, the practitioner aims to evaluate the effectiveness of “Concept Categorization Learning (CCL)” as a lesson theory by analyzing his own lesson record of “What makes Kappa Ebisen ‘Classic’?”. Two main results are as follows; 1) the author successfully proved CCL effective in Social Studies at the elementary school level through the lesson analysis. Prior to this, the author had provided in publication its structure, methods or patterns of CCL, but not the actual lesson record or the lesson structure of the whole unit due to the limited space. The detailed lesson record as well as the lesson analysis with the goals, contents, methods of the unit are provided in this article. Using the lesson structure of the known unit, the effectiveness of CCL was efficiently demonstrated in the concrete for the future dissemination of CCL. 2) The lesson analysis of the known unit described clearly the characteristics of CCL learning process. Based on the knowledge structure diagram and lesson plans, the author analyzed the relationship between its educational content (learning objectives of the unit) and required knowledge that shall guide students’ understanding, or between target questions and knowledge, or the method of scientific verification in learning process. The results confirmed that the unit contained three known learning processes :problem-solving, concept-categorization, and deepening social cognition of the attained concept. These findings should encourage curriculum development using of CCL. Further research will focus on CCL effectiveness in practices and CCL learning process for wider application.
