speaking accuracy

This study explored the relationship among working memory (WM), speaking accuracy and length of utterance of Iranian Intermediate EFL learners. The data were collected from 38 female EFL learners whose age range was between 12 and 15 studying English at a language institute in Tehran. First, an Oxford Placement Test (OPT) was administrated to ensure the homogeneity of the participants and based on the results of the test thirty homogenous learners were selected as the main participants of the study. Next, a working memory capacity test developed by Daneman and Carpenter (1980) was administered to the participants. Later, the researcher administered a speaking test on a topic appropriate to the level of the participants which was taken from Top Notch 1 (Saslow & Ascher, 2011). Then, the researcher recorded their voices and transcribed them in order to calculate the number of lexical words the students could articulate based on a formula developed by Gilmore (2004). Speaking accuracy was also measured using a formula developed by Gilabert (2004); In fact, the students' performance was rated by two experienced teachers.  Then, the Pearson correlation formula was utilized to analyze the obtained data. The results revealed a significant correlation between working memory capacity and speaking accuracy. Based on the findings, no significant correlation was shown between working memory and length of utterance. And finally, no significant correlation was depicted between length of utterance and speaking accuracy.

Dynamic assessment offers a holistic approach to evaluation by embedding assessment within instruction. Despite evidence suggesting the effectiveness of DA in language classrooms, there remains a reluctance among teachers to adopt DA practices. This reluctance stems from a lack of understanding of how DA models impact specific learning outcomes, particularly in speaking skills. One main contributing factor is the dominance of quantitative DA studies, which do not contextualize the differences between DA models. With an inductive thematic analysis design, this study explored the perceived effects of interactionist and interventionist DA models on speaking accuracy, fluency, and complexity among Iranian EFL students. Thirty undergraduate intermediate EFL learners from Islamic Azad University, North Tehran Branch, were recruited through purposive sampling. Each participant had received one hundred hours of speaking lessons with one of the DA models embedded before participating in a semi-structured interview. The analysis of participants' perceptions and reflections revealed that both DA models were well-received for improving speaking skills but had different effects on subskills. Learners perceived the interactionist model as an effective teaching method that improved their speaking accuracy and complexity but reduced fluency, while the interventionist model favored fluency at the expense of grammatical accuracy and complexity.

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.
