For this purpose, a sample of 120 male students from a private school in Tehran was selected through convenience sampling and based on availability. The participants were divided into four groups, and each group was given a different treatment. The first group was taught through meaning-focused input-oriented vocabulary tasks; the second group was instructed through meaning-focused output-oriented tasks; the third group received form-focused input-oriented vocabulary tasks, and the fourth group received form-focused output-oriented vocabulary instruction. At the end of the treatment, the participants in all the four groups were given a vocabulary comprehension and a vocabulary recall posttest. The results indicated that meaning-focused tasks were more effective than form-focused tasks on both vocabulary comprehension and recall. At the same time, input-oriented tasks turned out to be more effective than output-oriented tasks on only vocabulary comprehension. In vocabulary recall, input-oriented tasks were more effective when they were form-focused, while output-oriented tasks were more effective when they were meaning-focused. The results of this study can have implications for teachers, learners, and curriculum designers. %U https://ilt.atu.ac.ir/article_8061_32627960d7ff00142f9d1a2d0e2a4fde.pdf
