The current study aim's Finding out the effect of Triangle Listening Strategy on Iraqi intermediate pupil's achievement. Finding out the effect of triangle listening strategy on EFL Iraqi intermediate pupil's listening comprehension.Finding out the effect of triangle listening strategy on EFL Iraqi intermediate pupil's reading comprehension. To achieve the aims of this research and verify its hypotheses, non-randomized control Group pretest -posttest have been chosen. The pupils have been taught during the academic year 2024-2025 in English subject. The sample of the study consists of (60) pupils selected from the first class at janat AL-Iraq School for Girls in samaraa City. The sample has been divided into two groups Group (A) represents the experimental group who consists of (30) pupils who have been taught by using TLS Strategy. Group (B) represents the Control Group which also include of (30) pupils who have been taught using the prescribed method. Both groups have been equalized in such variables as parents' academic attainment, pupils' scores in previous schooling years, and the pretest of both groups. A posttest contains five questions, which are constructed to collect data. Face and content validity have been achieved. The reliability coefficient has been verified, and the researcher herself teaches both groups. The data is collected from the results of the posttest have been analyzed statistically by using a t-test for measuring the pupils' performance. The results show that there is a statistically significant difference between the mean scores of the experimental group and control group in posttest. Moreover, there is a statistically significant difference between the mean score of the experimental group in pre and posttest. which indicates that triangle listening strategy is more effective than the prescribed method. The study ends with recommendations and suggestions for further studies based on the obtained results.
