Abstract
The purpose of this study is to consider the significance of the instructional concept in Klafki's plan "epochaltypische Schliisselprobleme". His plan has attracted further attention as the theme of "Facherubergreifender Unterricht" that has been developed as an attempt of the curriculum reform in Germany. His plan gives "Facherubergreifender Unterricht" a theoretical framework and practical direction and shows a new plan of school curriculum. In this paper, I analyze Klafki's Plan "Schlusselprobleme" as a new plan of school curriculum. Then I show the instructional concept and learning principle in his plan and refer to the concrete examples of instructions. And I analyze characteristics, possibilities, and practical problems of this plan and suggest some idea to curriculum reform in Japan.
