This article is a record of educational practices to change the learning from contents base to the competency base, and this work was carried out in the teacher license renewal program and some undergraduate classes conducted by the author. In the former, the position of several prefectures, the cultivation of farm products and a characteristic of their circulations were treated. In the latter, the production of tea leaves was the main focus, and exploratory learning was suggested through comparative study for Kagoshima and Kyoto Prefectures. All of these educational goals are not "memorizing" but rather "thinking and understanding".
