L1

The current inquiry aimed at examining the effect of first language by Iranian learners as Foreign Language (EFL) in task preparation on their speaking accuracy, fluency and complexity. For this purpose, 40 Iranian EFL learners with intermediate level were selected based on a placement test, and divided into two equal groups. Then, the speaking fluency, accuracy, and complexity test was administered as the pretest. The treatment lasted for five sessions of 60 minutes. In these sessions, the learners did oral opinion tasks. In the first group, participants were supposed to spend 10 minutes to cooperate with a partner to read a proposed problem, discuss their solutions, and jot down by in a planning sheet. Within 10 minutes, they prepared for the task using only their L1 (Persian) for improving both speaking and writing skills. Following that, the participants were separated in various rooms, and were given two minutes to plan the task in English prior to doing the task. In contrast, the second group completed the planning sheet and prepared the task in English as their second/foreign language. The instruction lasted five sessions. At the final session, the speaking fluency, accuracy, and complexity posttest was conducted. The effects of the task planning conditions were analyzed and compared during and after the task performance. The data were analyzed via ANCOVA. The findings indicated that using L1 by Iranian EFL learners in task preparation significantly affected speaking accuracy, fluency and complexity. Finally, the pedagogical and theoretical implications of the study are provided.

Lewis (1993) recognized significance of word combinations including collocations by presenting lexical approach. Because of the crucial role of collocation in vocabulary acquisition, this research set out to evaluate the rate of collocations in Iranian EFL learners' writing production across L1 and L2. In addition, L1 interference with L2 collocational use in the learner' writing samples was studied. To achieve this goal, 200 Persian EFL learners at BA level were selected. These participants were taking paragraph writing and essay writing courses in two successive semesters. As for the data analysis, mid-term, final exam, and also the assignments of L2 learners were evaluated. Because of the nominal nature of the data, chi-square test was utilized for data analysis. Then, the rate of lexical and grammatical collocations was calculated. Results showed that the lexical collocations outnumbered the grammatical collocations. Different categories of lexical collocations were also compared with regard to their frequencies in EFL writing production. The rate of the verb-noun and adjective-noun collocations appeared to be the highest and noun-verb collocations the lowest. The results also showed that L1 had both positive and negative effect on the occurrence of both grammatical and lexical collocations.
