Conceptual Change in Regard to Childrens' Ideas about Solutions

Abstract

In this study, the types of teaching methods and strategies necessary to change the students' present understanding of solutions into a scientific concept are addressed, based on experimental teaching methods. To improve the teaching of solutions, ( 1) the concept of particles and (2) poster making like that used in model teaching methods such as CLIS were introduced. Based on these, experimental classes were conducted in order to observe the changes in the students' learning process of solutions. The following are the results : 1 . The advantage of the introduction of particles is that students can easily grasp the concept of solution as an image. This helps students form a more scientific concept of solutions. 2 . Poster making proved to be visually helpful for students to deepen their understanding of solution while they were forming images and modeling the phenomenon. Furthermore, it helped them re-evaluate their own understanding of what a solution is, through interaction with other students.
