The present study was conducted to "investigate the role of teachers' media literacy and the new communication technology 'Madyar' on students' learning in the experimental science course of the sixth-grade primary school boys in sari city." The research method was descriptive-survey. The statistical population of the current research was considered to be all sixth grade students of Sari city boys' schools along with their teachers who are working in the academic year of 2014-2015. Due to the limited number of sixth grade teachers, 200 samples were selected by simple random sampling from the students along with the teachers of the same grade. The methods of information collection are in the form of library study and field research. To collect data, a media literacy questionnaire, a questionnaire created by a researcher of the modern communication technology of the Madyar system, and a learning questionnaire were used, and the reliability of the test through Cronbach's alpha coefficient was calculated as 0.83, 0.82 and 0.80 respectively. Two statistical methods including descriptive statistics (central and dispersion indices) and inferential statistics (t test) were used to analyze the data. The results of the research showed that the media literacy of the teacher and the modern communication technology of the Madyar system have an effect on the students' learning in the experimental science course of the sixth grade, and in line with other researches, it will indicate the positive role of the use of the new communication technology on the students' learning.
