Abstract

The purpose of this paper is to discover the effect of convergence teacing using NOS in acid and base. The samples were treatment group 1 class and control group 1 class. As a result, treatment group's the understanding of acid and base was higher than the control group. The control group understood only text book's statement way. But treatment group knew reason and process of science knowledge formation. Through the result we can assure that convergence teaching using NOS is positive effect of concept development process. So convergence teaching is demanded.
