 Abstract
In this study, a survey was conducted of students of elementary through college on their conceptions of phenomenon related with dissolution, saturation, and extraction. The teaching strategies of elementary and secondary teachers related to dissolution phenomena were also investigated. Most of elementary and secondary school students thought of dissolution as a phenomenon in which particles broke into the spaces between other particles. This explanation called `space conception` can be sought in elementary school science textbooks. Some of high school students also had this type of thought. A concept of dissolution phenomenon as `hydration through attraction of solvent and solute` was held by most of students of 11th, 12th grade, and college. This explanation called `attraction concept` can be sought in high school chemistry textbooks for 11th and 12th grade. But many students of elementary through college used analogies and models related to `space conception` when they tried to explain the dissolution phenomena. This indicates that the `attraction concept` was not firmly established in the students` cognition. 90% of elementary school teachers thought and taught dissolution as a phenomenon in which two different size particles were mixing together like as mixing beans and millets. The model does not represent the attractions among solvent-solvent particles, solvent-solute particles, and solute-solute particles. This model only represents the space size effect (smaller size particles fitting into the spaces of larger size particles). Half of the secondary school teachers also had `space conception` and only 20% of the teachers had `attraction concept` Many teachers who had `attraction concept` used to represent explanation related to `space conception` for teaching dissolution.
