The purpose of this study is to analyze the connection of contents about metabolism contained in the biology textbooks from elementary school to college. For this purpose, the six subjects(photosynthesis, digestion, circulation, respiration, excretion, biological energy) of biological contents were selected from textbooks.
1. The contents about metabolism was classified according to six main subjects based on biology Ⅱ textbook. They were analyzed in terms of published section parts, learning objectives and contents from the view of each school unit.
2. 6(100%) of 6 subjects were introduced at the level of elementary school.
3. Connection from elementary school to middle school was C type(100%), that from middle school to high school showed B(50%) and C(50%). Connection from high school to college was analyzed as 17 and 83% for B. C type, respectively.
4. Considering theses results about connection of the biology sphere among school units, new concept diagrams were proposed.
