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

This study was inspired by VanPatten and Uludag’s (2011) study on the transferability of training via processing instruction to output tasks and Mori’s (2002) work on the development of talk-in-interaction during a group task. An interview was devised as the pretest, posttest, and delayed posttest to compare four intervention types for teaching the simple past passive: traditional intervention as the comparison group and three task-based groups were processing instruction, consciousness-raising, and input enhancement. The interviews and the interactions during the treatments were also analyzed qualitatively. Task-based instruction (TBI) proved significantly more effective than traditional intervention and processing instruction significantly outperformed all others on both posttests. Furthermore, processing instruction was the only task-based intervention to retain its improvement till the delayed posttest. Qualitatively, processing instruction led to true negotiation of meaning and deep-level learning, consciousness-raising led to massive negotiation over the function of the target structure and deep-level learning, input enhancement led to enormous unfocused interaction about meaning, and traditional intervention just led to interaction about the forms. It was concluded that a well-planned processing instruction is a promising intervention for focusing on language form; however, due to the strong points cited for the other two tasks, their roles should not be ignored.

مطالعه ی حاضر به بررسی تاثیر جنسیت براستفاده از مغلطه های بی قاعده بحث و استدلال در نوشته های (مقالات) استدلالی انگلیسی زبان آموزان ایرانی در سطح پیشرفته توانایی زبان انگلیسی می پردازد. مجموعه متون مورد بررسی این مطالعه شامل 120 نوشته ی زبان آموزان دختروپسر بود. سن و رشته ی دانشگاهی زبان آموزان دیگرمتغیرهای مستقل تحقیق بودند. نه نوع مهم مغلطه های بی قاعده در متون بررسی شدند و فراوانی های به دست آمده ازطریق تست آماری مانوا تحلیل شدند. به طورکلی برای مغلطه های بی قاعده ، نتایج تست های آماری مالتی وریت برای همه ی متغیرهای مستقل و تعامل آنها تفاوت معناداری را نشان نداد ولی سه مورد تفاوت مجزا مشاهده شد. در پایان تحقیق ، نتایج مطالعه در مقایسه با پژوهش های قبلی بررسی شده است و دستاوردهایی پیشنهاد شده است.

A long-standing debate among the vocabulary researchers is the depth of processing to learn vocabulary. This paper is a quantitative research which considers a revision in the “involvement load hypothesis” proposed by Laufer and Hulstijn in 2001. It investigates the role of proficiency and evaluation in this hypothesis in order to better reveal its potential contribution to vocabulary learning. It was based on task-induced involvementthat comparesdifferent tasks in incidental vocabulary acquisition in EFL context. The participants were 66 learners fromtwo different English institutes who were classified into two major high and low proficient groups based on Nelson Proficiency Test. The participants in each group were randomly assigned to three tasks prepared to compare“moderate”, “strong”, and “no evaluation” in involvement load hypothesis.The “strong evaluation”subgroup (making original sentences) in low proficiency supported Laufer and Hulstijn’s hypothesis and yielded better retention of the target words. The study suggests that the level of proficiency and evaluation in task induced involvementneeds reconsideration. The results have implications for language teachers, materials developers, and syllabus designers.
