Digital communication technologies could play a pivotal role in the realm of learning, entertainment, and education for children, and could significantly affect the nature of commercial relations with children. The use of media as new communication technologies for children over the past decade has hosted many researches. The present study aimed to determine the effect of advertising literacy education on 6th-grade primary school female students' critical thinking skills in facing the media commercial messages in the city of Dezful in 2019-2020. The population consisted of all the 6th-grade primary school students in the city of Tehran, of which 60 students were selected using the random clustering method and randomly assigned into two groups of experiment and control. The tool used in this study was Cornell Critical Thinking Test (CCTT), and analysis of covariance was used to analyze the data. The results showed that advertising literacy affected students' critical thinking. The effects on students' inductive reasoning, deductive reasoning, and observational analysis of advertising messages, credibility, and hypothesizing power were found significant.
