Both students and teachers consider the economic concepts as to be difficult. They need the medium approaching the economic concepts easily. In this point, prototype model is better than attribute model, and using diverse examples flexibly better than applying average-representative prototype strictly. In order to solve these problems, this study selects, develops, and shows the examples of economic concepts. These concepts include scarcity, opportunity cost, factors of production, capital, distribution, comparative advantage, and FTA. Using these examples of economic concepts, teachers can teach the difficult economic concepts easily and protect students from misconception.
