This action research study aimed to improve phonological awareness of young learners in Turkish EFL context. In total, there were 56 students from the 5th, 6th, and 7th grades at a secondary state school. The students' phonological awareness levels were measured via the Phonological Awareness Skills Test (P.A.S.T.) in pre-test, immediate post-test and delayed post-test design. Their scores were analysed through statistical procedures. When the mean scores of the pre-test, immediate post-test and delayed post-test were compared, it was found out that the scores in the immediate post-test and delayed post-test increased. A non-parametric Friedman test of differences among repeated measures was conducted and rendered a significant Chi-square value. Thus, it was revealed that there was a statistically significant difference among the P.A.S.T. scores of the participants measured before the in-class activities, after the in-class activities, and after a six-week follow-up. The findings displayed the importance of employing various activities to improve the phonological awareness of young learners. Educational implications are also discussed.
