Bulletin of the Faculty of School Education, Hiroshima University. Part I

The purposes of this study are to clarify the structure and characteristics of the concept 'photosynthesis' of teacher trainees by analyzing their concept maps, and to discuss problems of learning and teaching about photosythesis. The main results are as follows: First, the idea has been established that 'photosynthesis' is a function that makes 'sugar' from 'carbon dioxide' under 'light'. Secondly, in their concept maps 'molecule' links to 'photosynthesis' indirectly through 'carbon dioxide' or 'sugar' rather than directly. Lastly, in spite of importance of the relation between 'photosynthesis' and 'energy' in science teaching, knowledge about energy is not enough scientifically exact, and appropriate relations are not made between the concept 'energy' and other concepts. In order to promote understanding of energy in the concept 'photosynthesis', therefore, it is necessary to improve not only means and methods of teaching about photosynthesis, but slso science curricula in schools.
