Complexity

Research findings reported to date indicate that carefully planning speech while performing a task increases second language (L2) learners’ attention to formal aspects of their discourse. The evidence, however, is mostly based on performance analysis with respect to the linguistic measures of complexity, accuracy, and fluency. To enhance the psycholinguistic validity of current findings, the present research adopted a process-product approach to analyze L2 learners’ performance and attention shift as indicated by the occurrence of pauses in their speech. The study involved thirty Iranian learners of English as a foreign language (EFL) who were divided into two groups of fifteen. Whereas participants in the first group were given unlimited time to carefully plan while performing a narrative task, their counterparts in the other group completed the same task under time constraint. Following participants’ performance, both performance analysis and retrospective interviews were conducted to collect their protocol data. The results revealed that carefully planned speech is characterized by increased complexity and accuracy and reduced fluency stemming from attention being primarily focused on syntactic encoding, lexical choice, and phonology instead of conceptualizing the message. The outcomes are discussed in light of their theoretical and pedagogical implications.

Purpose: This study aimed at investigating the effect of competency-based approach on enhancing complexity, accuracy, and fluency of writing of pre-service teachers. Methodology: To this end, an Oxford Quick Placement Test (OQPT) was administered to 100 Iranian pre-service teachers studying at Farhangian University, of whom 40 upper-intermediate learners were selected and assigned to an experimental group (n = 20) and a control group (n = 20). The selected participants were both male and female and aged from 19 to 22. Both selected groups were then given a writing test as the pre-test. Subsequently, the experimental group received the competency-based treatment and were proposed to some real-world issues and there was no time limit. However, the traditional styles used for improving the writing skill of the subjects in the control group and a specific time limit was considered for the subjects to do the job. After that, a writing post-test and an attitude questionnaire were delivered to the participants. The obtained data was analyzed using one-way between group analysis of covariance (ANCOVA) and one-sample t-test. Findings: The results indicated no significant difference between pre-test and post-test scores of the control group, whereas, the post-test scores of the participants in experimental group were significantly better than their pre-test scores especially regarding complexity. Conclusion: The findings suggest that the teachers should take competency-based approach into consideration in their target language classes to have a more fruitful educational process.

There is ample research evidence indicating that task implementation options and design features differentially affect the linguistic quality of second language (L2) oral output. The overarching aim of the current research was to add to the available body of research findings by investigating what effects the combination of two task implementation options, namely pre-task planning and post-task transcription, exerts on L2 learners’ focus on form. The study involved sixty Iranian L2 learners who were presented with a picture story to be narrated under one of the following four conditions: pre-task planning (PTP), post-task transcription (PTT), both pre-task planning and post-task transcription (PTP/PTT), and control. Findings showed that while pre-task planning increased fluency and complexity, the anticipation of post-task transcription enhanced focus on form as indicated by more accurate performance. More importantly, pre-task planning along with the foreknowledge of post-task transcription of performance made for an exponential increase in accuracy, a gain which was achieved to the detriment of complexity. The outcomes are of pedagogical significance in that they lend support to the efficacy of using pre-task planning opportunity along with the anticipation of post-task transcription to elicit the highest accuracy level while learners are primarily concerned with conveying meaning.

Though applied linguistics has observed a rise in language acquisition investigations within the complex dynamic systems theory (CDST) paradigm, the majority of research endeavors have been centered on the development of learners' first language (L1) or second language (L2). Limited research exists on multilinguals’ L3 acquisition/development, with even fewer studies considering the development of learners’ speaking skill in L2, and L3. The present study aimed to address these gaps by adopting a CDST approach to analyze the development of fluency, accuracy, and complexity in L2 (English) and L3 (French) speaking skills among five undergraduate Iranian EFL junior students of Translation Studies at Jahrom University over one academic year. The students were at an intermediate level in English language and their French language proficiency was at the beginner level. The participants’ speaking ability in both languages was closely examined and analyzed regarding their development of fluency, accuracy, and complexity within a quantitative design. Findings depicted that the aspects were developed in non-linear, chaotic, and emergent patterns in multilingual learners’ L2 and L3 speaking skill. Moreover, the findings indicated that these elements in multilingual learners' speaking were interconnected and influenced each other over a period of time. The discoveries have some significant implications for L2 and L3 language teaching, such as creating flexible learning and teaching environments, fostering emergent behavior in language classrooms, encouraging learners to have a self-organizing and autonomous role in language learning, having sensitivity to the diverse needs of learners, and fostering a collaborative learning environment.  

Findings on recast as feedback on learners’ erroneous forms tend to be less than conclusive or confirmatory. Also, the conventional formulations in literature give partial accounts of recasting as an effective methodological practice. The present study proposes recast enriched by negotiation (REN) on the learners’ part as an alternative. For investigating the hypothetical effect, three all-female groups were concentrated on, namely explicit feedback, recast and REN. Summary writing task as post-test concentrated on the learners’ accuracy in terms of error-free T units, and complexity regarding word per sentence ratio as well as lexical density. One-way ANOVA for three independent samples and post hoc analyses revealed that accuracy and word per sentence ratio did not vary significantly; however, lexical density improved as a result of REN. Findings and implications of the study are discussed in the light of methodological potentials and literature.  

Writing by which students can be assessed plays an important function in the education process. By considering this fact, investigating the impact of graphic organizer strategy on improving Iranian intermediate EFL learners’ complexity of written performance was the main goal of this study. 40 intermediate EFL learners were selected as the participants of the study on the basis of findings of Preliminary English Test. After that, they were randomly divided into two experimental and control groups. To assess the initial writing ability of participants, two groups were given a pre-test prior to the treatment. After applying traditional method to the control group and the graphic organizer strategies to the experimental group, both groups received a post-test to examine the effect of materials. To examine the effectiveness of the treatment, an independent samples t-test was conducted. To see the progression amount between pre-test and post-test of the experimental group, a paired samples t-test was also employed. The findings of the study indicated that graphic organizer strategies improved the learners’ complexity of written performance. The results have some implications for EFL/ESL teachers, students, test and materials developers, and syllabus designers.

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.

This study examined how Iranian intermediate EFL learners' writing complexity, accuracy, and fluency were affected by collaborative online writing using Wikis. The language proficiency of 75 EFL learners was gauged based on their performance on the Oxford Quick Placement Test (OQPT). They were intermediate male and female EFL learners studying English at three language institutes in Shahrekord, Iran. The participants were then split into two groups at random: a Wiki group (WG), and a control group (CG). Afterwards, learners in the control and experimental group were given a cause-and-effect prompt as a pre-test, and their writing complexity, accuracy, and fluency were assessed using CAF measures. Following the pre-test, the participants in the experimental group began a six-week training period in the collaborative environment of Wiki. The same instructional materials and procedures were presented to the control group, but in a non-collaborative, face-to-face setting. Similar to the writing pre-test, a writing post-test was given to both groups at the end of the intervention, and the writings were graded. In comparison to the conventional methodology, the results obtained revealed that the instructional method via Wiki was advantageous and effective in enhancing writing skills. This result is consistent with theories supporting the use of technology-based approaches in EFL writing settings. The main outcome of this research is that the ease and viability of teaching and learning writing are significantly and meaningfully influenced by giving learners control over their learning through Wiki.

In recent decades, many second language acquisition (SLA) researchers have identified the leading role of organizing sequentially cognitive tasks in Task-Based Language Teaching. Presenting types of different task sequence has become increasingly crucial for syllabus designers. This investigation examines the theoretical basis of task sequencing, which claims that pedagogical tasks should be developed and ordered cognitively from easy to complex. The current study aims to compare the performance of English learners in sequenced and isolated familiar tasks. Sixty EFL learners studying at the intermediate level in two private language institutes participated in this research. They were randomly selected as one experimental and one control group, each comprising 30 subjects. Before starting treatment, all the participants took a listening comprehension test as a pretest. The treatment took place over one semester, during which the subjects performed simple-complex familiar sequenced tasks while the control group received familiar randomized tasks. After treatment, the posttest of listening comprehension, which contained two complex task features, i.e., - Here-and-Now and - Planning time, was employed. The independent-samples t-test showed that the experimental group who received simple-complex sequenced tasks outperformed the control group in listening to complex tasks. The findings supported the employment of simple-complex sequencing tasks to foster listening task complexity performance.

This study examined the impacts of providing regulatory focus feedback (RFF) in the forms of prevention and promotion as well as reference of comparison feedback (RCF) in the forms of normative and self-referential on EFL learners’ speaking complexity, accuracy, and fluency (CAF) in online speaking courses. For this purpose, 100 intermediate EFL learners in a language institute were randomly assigned into four experimental groups and one control group (N=20). Language learners were required to respond to two speaking tasks from the IELTS exam before and after receiving 16 sessions of the intervention. The data were subjected to ANCOVA analysis and paired samples comparisons. The results showed that the participants’ speaking performance was better in all four experimental groups compared to the control group. Moreover, the superiority of self-referential feedback in improving the participants’ oral production ability over normative feedback was demonstrated. Prevention-focused feedback was shown to be influential in improving accuracy. Finally, practical implications for how EFL teachers can enhance language learners’ oral production ability are discussed.

This study investigated the effectiveness of two different scopes of corrective feedback on enhancing the complexity, accuracy, and fluency of L2 written productions among 150 intermediate EFL learners participating in intact online courses. The corrective feedback scope includes highly focused and comprehensive feedback delivered via digital platforms in synchronous and asynchronous formats. Participants were divided into five groups: synchronous highly focused feedback, synchronous comprehensive feedback, asynchronous highly focused feedback, asynchronous comprehensive feedback, and a control group receiving corrective feedback via traditional methods, characterized by the indiscriminate identification and marking of all errors. Results across the feedback groups regarding their impact on complexity, accuracy, and fluency in EFL learners' written productions indicated a significant effect on accuracy, while complexity and fluency showed no significant differences based on feedback scope and delivery modality. The results of this study have several important implications for educators, material developers, and policymakers in the field of language education. For teachers, adopting synchronous feedback strategies could significantly enhance the accuracy and complexity of students' written work.
