Abstract
The aim of this study is to elicit the level of understanding of students at different grades on “dissolution” as a concept and to identify how they visualize the dissolution process at microscopic level. To reach these aims, a test, which comprises of drawings and open-ended questions, was devised and administered to 441 students at different grades (from Grade-7 to Grade-10). The data obtained shows that students have misconceptions on dissolution. Specifically, students used terms such as melting, disappearing and decomposition instead of dissolution. Moreover, it was found out that students have difficulties in visualizing dissolution process at microscopic level and tend to attribute macroscopic properties to events at microscopic level. As a consequence, it is concluded that although there is no clear certain results that show a direct relationship between grade and understanding level, in most cases, understanding level of students at Grade-9 and students at Grade-10 are better than those at lower grades. In the light of the results, it can be suggested that HyperCard, hypermedia environment or simulations should be developed to help students to visualize dissolution process at microscopic level.
