The use of knowledge integration framework will result in relating different individual ideas of learners and will lead to a collective idea about concept of a phenomena among learners. Using dynamic visualizations, learners will be able to view and test phenomena in the non-visible levels. So, this study was conducted with the aim of examining the effect of using dynamic visualizations and knowledge integration framework on chemistry learning of tenth grade high school female students. In this research, the pretest-posttest, quasi-experimental method with control group was used. Statistical Population consisted of all tenth grade high school female students in Tehran, using convenience sampling method, 34 students were selected as the sample and were randomly assigned into two experimental and control groups. Measuring the instrument was a researcher-made tool for measuring academic achievement in chemistry lesson consisted of 13 items designed to test the relationship between learners' ideas towards a concept and different levels of chemistry. Before starting the course, a pre-test was performed in both groups, dynamic visualizations and knowledge integration framework strategy was used in experimental group in six 60-minutes sessions while the control group were taught using traditional teaching method in five 60-minutes sessions. Post-test was conducted in both groups. Results of covariance analysis confirmed the effect of using knowledge integration framework and dynamic visualizations in comparison with the traditional teaching method and the difference between the experimental and control group in terms of chemistry performance after the posttest (F=41. 462, p<0.0001). Findings showed that the group which has been taught using the dynamic visualizations and knowledge integration framework, established a better relationship between different levels of chemical reactions. In addition, the use of knowledge integration framework helped students to have a common understanding toward concepts of phenomena and systematically understand the connections between different ideas in a phenomenon.
