Electrochemistry is difficult to learn due to its abstract concepts involving macroscopic, microscopic, and symbolic representation levels. Studies have shown that students can visualize and improve their understanding of chemistry by using interactive computer animation and simulation. This study reports the effect of interactive computer animation and simulation module named “Interactive Electrolysis of Aqueous Solution” (IEAS) developed to aid students in learning electrolysis. A pre and post-test control quasi-experimental design was carried out to investigate the effects of the IEAS on students’ achievement and motivation in electrochemistry topics. This study involved 62 16-years-old male students from two different secondary schools. Pre and post electrochemistry achievement tests (EAT) and pre and post- Instructional Material Motivation Surveys (IMMS) were used. For EAT, using one-way ANOVA, it shows that there was a significant difference in the post-test mean score in this study on the understanding of the electrolysis concept between students in the treatment and control groups [F (1, 60) = 5.15, p <0.05]. The qualitative results also provided evidence that the students in the treatment group had a better conceptual understanding than the control group, especially at the microscopic representation level. For the IMMS test, there was a significant difference between the treatment and control groups in terms of the mean score of the post motivation IMMS test where p <0.05 in chemistry learning [F (1,59) = 266.89, p <0.05].  Thus, it can be concluded that IEAS has an impact on enhancing the students’ understanding of the electrolysis concept, and the students are more motivated to learn electrochemistry.

 Aim of this study is to determine the effect of environmental education program integrated into preschool education aged between 48-66 months on children’s mental model development about “environment” concept. Triangular mixed design was used in this research. Quantitative dimension of the study was carried out with quasi-experimental design with control group and qualitative dimension of the study was carried out with using phenomenological method based on social constructivist philosophy. Study group of the research consisted of 52 children from experimental and control groups. Statistically significant difference was observed in the scores of children in the experimental and control groups from DAET-R (U= 44, z= -5.44, p= .000, r= .75). Mental model development about environment of the majority of the children from the experimental group reached to an expected level. However, no development was obtained in the mental model development of the children in the control group. Results also showed that 80.8% of the children from experimental group defined environment as a place which people, animals and plants live together and the amount of the children from control group who defined environment similar to this level is 26.9%. In addition, there was no significant difference in the total pre-test and post-test DAET-R scores of children from the control group (z= -1.401, p > .05) and significant difference was observed in the pre-test and post-test DAET-R scores of children in the experimental group in support of post-test results (z= -4.126, p < .05).
