the help of mobile tools for teaching mathematics in primary school

The purpose of this study was to investigate the effectiveness of blended learning using mobile technology on academic achievement of elementary fifth grade students in mathematics by semi-empirical method (pretest and posttest with control group). the statistical population is all fifth grade students of eqbaliyeh city which was selected using the available sample method of a 30 person class and were randomly divided into two groups: experiment 15 and control 15. the tools used include the researcher-made software of mathematical decimal numbers and the researcher-made test of mathematical decimal numbers. the validity of the researcher-made test was confirmed by experts opinion, and the reliability of the test was calculated to be 0.85 by cronbach's alpha. covariance analysis test was used to evaluate the research hypotheses. the results of the data analysis showed that the mean scores of the experiment group were higher than that of the control group and the application of the blended learning by using mobile technology (mobile) was effective in the academic achievement of the elementary fifth grade students.
