Abstract

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