The content of oxidation-reduction in the chemistry textbooks from middle school to college was analyzed to see the effective connection of curricular articulation. For this purpose, oxidation-reduction content between the school unit were selected in chemistry textbooks and formed five types of classification from groups of "first concept", "same concept", "overlap", "development" and "gap".
The result indicated that there was a deep big gap from middle school to senior high school and the effectiveness from senior high school to college was looked acceptable. Finally, the new concept maps between the school unit were suggested.
