| Abstract: | The purpose of this study is to investigate the effects of the cooperative learning approach based on conceptual change conditions
over traditional instruction on 10th grade students' conceptual understanding and achievement of computational problems related
to chemical equilibrium concepts. The subjects of this study consisted of 87 tenth grade students from two intact classes
of a Chemistry Course instructed by the same teacher. One of the classes was randomly assigned as the experimental group,
which was instructed with cooperative learning approach based on conceptual change conditions and the other class was assigned
as the control group, which was instructed with traditional instruction. Chemical Equilibrium Concept Test (CECT) was administered
to the experimental and the control groups as pre- and post-tests to measure the students' conceptual understanding, and Chemical
Equilibrium Achievement Test (CEAT) was administered to the experimental and the control groups as a post-test to measure
the students' achievements related to computational problems. Science Process Skills Test was used at the beginning of the
study to determine the students' science process skills. Multivariate Analysis of Covariate (MANCOVA) was used to analyze
the data. The results showed that students in the experimental group had better conceptual understanding, and achievement
of computational problems related to the chemical equilibrium concepts. Furthermore, students' science process skills were
accounted for a significant portion of variations in conceptual understanding and achievements related to the computational
problems. |
