The current study adopted a qualitative-quantitative design to compare the effects of output-based production (OBP) and input enhancement (IE) as two teaching techniques on a group of EFL learners’ writing and also to seek those learners’ perceptions on the two instruction procedures. Accordingly, 65 intermediate learners were selected through convenience nonrandom sampling from among 94 students in intact classes based on their performance on a sample proficiency test (the test had already been piloted among 30 learners). These 65 learners were subsequently divided into two groups consisting of 33 learners in the OBP group and 32 in the IE group. The researchers also made sure that the learners in both groups were homogeneous in terms of their writing prior to the treatment. Next, the treatment in both groups commenced. Once the treatment was over, the researchers gave both groups the same writing posttest. The results of the statistical analysis indicated that the IE group outperformed the OBP group significantly in their writing. The participants further sat for a semi-structured interview comprising five questions about their perception regarding both instructions which demonstrated that the IE group was generally more satisfied with the course than the OBP group. The findings of this study suggest more attention to the incorporation of IE in both English language schools and pre- and in-service teacher training programs.
