A Cross-Age Study of Different Perspectives in Solution Chemistry from Junior to Senior High School
Calik, Muammer
International Journal of Science and Mathematics Education, v3 n4 p671-696 Dec 2005
This study reports on research examining what students think about aspects of solution chemistry and seeks to establish what alternative conceptions they hold in this area. To achieve this aim the researchers developed a test comprising of open-ended questions that evaluated students understanding of solution chemistry. The test was administered to 441 students selected randomly from different grades, grade 7 through grade 10. The research findings suggest that students have difficulty at comprehending the investigated concepts in solution chemistry. Alternative conceptions about the concepts of dissolution, chemical bonding, evaporation and condensation influence latter learning. Interestingly, the grade 9 students have the least percentages, except for Item 3, amongst grades in terms of alternative conception. Also, students' alternative conceptions are also stored in long-term memory and interact with each another. In the light of the findings, it can be suggested that the future research may need to focus on classifying of students' responses in terms of categories in understanding such as propositions, strings, images, episode, intellectual skills and cognitive strategies.
