This study investigated the comparative effect of teaching idiomatic expressions through practicing them in conversation and paragraph writing on intermediate EFL learners’ idiom learning. The participants were sorted out of a population of 134 intermediate students in Zabansara Language School in Khorramabad based on their scores on a Preliminary English Test (PET) and an idiom test piloted in advance. The selected 84 participants were divided randomly into three groups: two experimental groups, namely, conversation and paragraph writing groups, and one control group. The two experimental groups received different treatments. In one class, idioms were taught and learners were asked to make a conversation practicing the new idioms, and in the other class, they were asked to write short paragraphs using the idioms. In the third class, the control group, the new idioms were presented and then practiced through different written exercises. At the end of the treatment period, the researchers administered an idiom posttest. The analysis of the collected data revealed that using new idioms in conversation and paragraph writing helped students learn idioms more efficiently than just practicing them through different written exercises. Moreover, the use of idioms in conversation proved to be more effective than using them in paragraph writing. The findings can have implications in preparing materials, teaching/learning foreign languages, and designing syllabus.

This study investigated the role of interactive output tasks in developing EFL learners’ vocabulary knowledge. The participants were 103 elementary female Iranian EFL learners who were randomly divided into three groups: input-only, input-output-no-interaction, and input-output-interaction. After all participants took a placement test and a vocabulary pretest, the input-only group was exposed to input tasks, while the other two groups received both input and output tasks with or without interaction. Then, all the participants took a vocabulary posttest. The results of ANOVA and Kruskal-Wallis tests showed that the participants in both the input-output-no-interaction group and the input-output-interaction group outperformed the ones in the input-only group in the vocabulary posttest (in both the overall vocabulary test and in the productive vocabulary section). Moreover, the results of the t-test and the Mann-Whitney test revealed that the participants in the interaction and no-interaction groups performed similarly on both the overall vocabulary posttest and the productive vocabulary section. The findings of this study support the idea that output is a facilitative factor for the acquisition of L2 vocabulary and, specifically, productive vocabulary development. The results also suggest that both interactive and non-interactive output-plus-input tasks can lead to higher achievement in vocabulary knowledge compared to the input-only condition lacking output tasks
