A hypermedia environment to explore and negotiate students' conceptions: Animation of the solution process of table salt

摘要: This article describes the characteristics and values of hypermedia for learning chemistry. It reports how a environment was used to explore group 11th grade chemistry students' conceptions table salt dissolving in water. then presents by students negotiate meaning two conceptualizations about process water: (a) transformation solid liquid, (b) chemical combination solute solvent. traces nature solution salt. The findings this study indicate that can be explore, negotiate, assess submicroscopic aspects Further, discusses successes difficulties pertaining environment, an account improved version future study.
