In this paper the contents of CEA, CHEMS and KAGAKU B (four kinds) textbooks are studied comparatively. CBA and CHEMS are based on the spirit of inquiry and the development of chemical concepts, but KAGAKU B is not based on a strong philosophy. In comparison of a number of compounds, KAGA KU B is much than CBA, but less than CHEMS. And among them there are many differences. Many valuable concepts in chemistry are introduced and developed well in CBA and CHEMS, but less in KAGAKU B. Pye and Anderson compared a achievement of students in CBA, CHEMS, conventional, and other approaches in South California, U.S.A. The results that CHEMS and conventional approaches are better than CBA. I think CBA is too logical approach. But KAGAKU B is too factual approach.
