The purpose of this study is to probe whether there is a significant effect of 5E learning cycle model as compared to traditional instruction and gender on tenth grade students&rsquo / understanding in the particulate nature of matter concepts and their epistemological beliefs and to investigate whether there is an impact of 5E learning cycle model and traditional instruction in promoting the understanding of the nature of science.
Pilot study was performed for the instruments in the between April and June 2009. Treatment was conducted between October and December 2009. Participants were 113 students from one high school in Ankara. Two experimental groups and two control groups were randomly formed from four classes. Before and after the treatment, pre-tests and post-tests were administered and semi-structured interviews were conducted. Treatment was executed throughout the five weeks. While 5E learning cycle model was used in the experimental group, traditional instruction was used in the control group. According to MANCOVA results, there was a significant mean difference between groups on the collective dependent variables of the particulate nature of matter concepts and epistemological beliefs toward chemistry and chemistry courses. This effect was favor of the experimental groups. Also, there was no significant mean difference between post-test mean scores of girls and boys and for the interaction of treatment with gender on the collective dependent variables of the particulate nature of matter concepts and epistemological beliefs toward chemistry and chemistry courses. Moreover, the mean scores of students in the experimental group on the understanding of the nature of science were higher than those of students in the control group. Responses of the students in the interviews supported their responses in the tests.
