The Effectiveness of Using, Visual organization Knowledge, Understanding and Using the Empirical Concepts

The purpose of this study was to evaluate the effectiveness of using visual organizers on the knowledge, understanding and application of the concepts of the sixth grade elementary experimental sciences. The research design used in this study was a quasi-experimental design with post-test pretest with comparison groups in which the effectiveness of training based on the presentation of visual organizers on the three cognitive efficiencies of knowledge, perception, and application was evaluated. The subjects of this study were 120 sixth grade elementary school students in Bonab city who were selected by multi-stage cluster sampling method with validity and reliability. The subjects' learning rate before and after presenting the visual organizers in the groups, the teacher-made academic achievement test was valid and reliable. The results of data analysis using multivariate analysis of covariance showed that the use of video organizers during teaching and when reviewing and summarizing lessons, has a significant effect on increasing the learning of learners' cognitive domains. The findings of this study show the practical implications of using video organizers in the education process.
