The purpose of this research is to investigate the effectiveness of using multimedia in the flipped class on learning, retention and motivation of elementary school students in mathematics. The importance of choosing this topic is because the students of the new generation use technology more and traditional teaching methods can no longer meet the needs of students. For this reason, it is necessary for education specialists to use new teaching methods and especially new educational technologies in their teaching. One of the new teaching methods is using multimedia in the flipped classroom. The current research is one of the types of quantitative-experimental research in which a researcher-made test was used to collect learning and retention data, and Tuan, Chin and Sheh questionnaires were used to collect motivation data. The statistical population of this research was all elementary school students of Selmas city, who were selected by cluster sampling of ۴۰ students, and of these, ۲۰ people were in the control group (the group that was taught by the traditional method) and ۲۰ people were in the experimental group (the group that was taught by the researcher's multimedia made in the flipped classroom method) were placed. Analysis of covariance was used in data analysis. It was used to measure the validity of learning and retention and motivation tests according to primary education experts and professors. Also, for the reliability of learning and memorization tests, the halving method was used, and Cronbach's alpha was used for the reliability of the motivation questionnaire. The results of data analysis showed that the use of multimedia in the flipped class has a positive effect on retention , but it has no effect on learning. Also, this method was effective on two components of motivation, but not on the other four components of motivation.
