标题：The Effect of Animation Enhanced Worksheets Prepared Based on 5E Model for the Grade 9 Students on Alternative Conceptions of Physical and Chemical Changes
摘要：AbstractThe aim of this study is to determine the effect of teaching material based on 5E model for overcoming the alternative conceptions related to physical and chemical change. A quasi-experimental design and one control group (CG, N = 40) and one experimental group (EG, N = 40) were used. While the control group taught traditional instruction the experimental group received animation enhanced worksheets-based instruction. Teaching material included worksheet enriched with animations related to physical and chemical changes. TheConcept Achievement Testconsisting of 17 open-ended questions was used to collect data as pretest and posttest. Results indicate that while there is no statistically significant difference between groups in pretest, performance of EG students is greater than the CG ones in posttest. And also, the EG students are better in remediating their alternative conceptions related to the physical and chemical change. Based on the study, it is concluded that animation enhanced worksheets may be effective way to improve student's understanding of basic concepts and to dispell students’ alternative conceptions.
