Drawing on the team-teaching model of multiple instruction, this study aimed to investigate the impact of team-teaching on the English language achievement of Iranian high school students. The study employed a sequential explanatory mixed-method design, consisting of two phases for data collection and analysis. In the quantitative phase, 40 male and 40 female students aged 16-18 were conveniently sampled from tenth-grade high schools in Lahijan, Iran. They were divided into two experimental and two control groups. The experimental groups received instruction using the team-teaching model, while the control groups received traditional instruction. Data analysis was conducted using one-way ANOVA, which revealed a statistically significant improvement in the performance of the experimental groups compared to the control groups. Due to gender differences, the results showed no significant disparities in the outcomes achieved by male and female students. In the qualitative phase, the same participants from the experimental groups were asked to provide open-ended responses regarding the advantages and disadvantages of the team-teaching method, using a questionnaire developed by Jones and Harris (2012). The responses were carefully examined using open coding techniques, and common themes were identified through systematic comparison of the codes. The findings indicated that team-teaching offered a wide range of benefits. Considering gender differences, it was evident that male participants perceived the benefits of the team-teaching model to outweigh the drawbacks more than their female counterparts. These findings have pedagogical implications for Iranian teachers and theoreticians in the field of English language instruction.

The current study attempted to investigate the effect of a newly tailored curriculum on students’ general English achievement across gender as compared to the standard curriculum at Iranian tertiary education. The participants were 120 non-native undergraduate students of Pre-requisite General English course majoring in different disciplines at Ayandegan Institute of Higher Education in Tonekabon city. They were assigned into four groups including female control and experimental as well as male control and experimental. The experimental groups received teaching through the tailored curriculum and the control groups through the standard one. All the groups were given pretest and posttest on general English achievement. In order to analyze the data, a Kolmogrove-Smirnov test and an Independent Samples T-test were utilized. The findings of the study indicated female participant’s outperformance compared to the male ones, after being treated with tailored curriculum (TC) and standard curriculum (SC). However, the male participants experienced higher degree of progress after receiving TC as compared to SC, while such progress was not seen for the female.

The current study examined the effect of scaffolding through presenting examples and pictures on EFL learners’ vocabulary learning and retention.For this purpose, six research niquestions were posed and a quasi- experimental design was applied with two groups of learners who were selected as experimental groups. This research was carried out with a sample of 60 English students from Iran Zaban Institution. The data were collected using three instruments. Primarily, a standard test of Nelson which had 50 items was used to assess general proficiency of the learners for the purpose of their homogeneity. Then, in order to investigate the learner’s lexical knowledge before executing the scaffolding strategies used by examples and pictures, the researcher prepared a vocabulary test used as pretest. At the end of the treatment the students’ lexical knowledge was assessed by a posttest. Also a vocabulary test was used in order to measure their vocabulary retention after two weeks. The results indicated that employing examples helps vocabulary learning as well as retention. In addition, it was shown that using pictures helps both vocabulary learning and retention, and employing examples and pictures have almost the same effect on vocabulary learning. Finally, the results are discussed and compared with the previous ones, implications are explained, and some suggestions and recommendations are provided.

The proficient use of parallel structures in essay writing plays a vital role in enhancing language proficiency among English as a Foreign Language (EFL) learners. Exploring effective instructional strategies, such as input flooding, can contribute significantly to improved writing outcomes. This study investigates the impact of input flooding techniques on the utilization of parallel structures in essay writing among EFL learners, comparing two instructional settings: flipped online and flipped face-to-face. A total of 73 participants were randomly assigned to three groups: the flipped online group (n=24), the flipped face-to-face group (n=22), and a control group (n=27). In the flipped online approach, the participants were exposed to input flooding through pre-recorded videos and received online feedback on their essays, allowing for extensive exposure to parallel structures. In the flipped face-to-face approach, the participants received the same instructional materials emphasizing relevant structures and engaged in activities to promote the use of parallel structures. The control group followed their regular instructional method without any specific intervention. Following the treatment sessions, all participants underwent a post-test essay assessment to evaluate their proficiency in utilizing parallel structures. The results indicate that the flipped online group demonstrated the highest level of proficiency, highlighting the effectiveness of input flooding techniques in promoting the use of parallel structures in essay writing. Nevertheless, the flipped face-to-face group also exhibited improvement compared to the control group, suggesting the potential benefits of incorporating input flooding in the face-to-face approach. The study indicates that employing input flooding techniques, particularly in a flipped online instructional environment, can significantly improve EFL learners' proficiency in using parallel structures in essay writing. Moreover, the implications extend beyond the classroom, offering valuable insights for educators and policymakers to refine instructional strategies and shape language learning policies effectively.

Corpus linguistics has developed a new avenue of research in the field of language teaching. One important aspect of corpora is concordancing. Drawing on the concept of concordance, this study aimed to explore whether concordancing can effectively improve the vocabulary learning and retention of Persian EFL learners. To this end, 50 homogenous learners were randomly assigned to experimental and control groups. Vocabulary pre-test and post-test, and interviews were employed to collect the data. The results of this mixed method study revealed a statistically significant difference between the control and experimental groups on post-test scores; furthermore, the experimental group’s retention of these items was weaker in the delayed post-test. Finally, the results of interviews showed that this approach increased learners' enjoyment and interest in learning, led to a greater appreciation of particular uses of words in various contexts, enhanced learners' command of the target language's linguistic rules and patterns, facilitated the development of autonomy, and improved learners' language awareness.

Although there is an increasing amount of research examining the efficacy of Witten Corrective Feedback (WCF) in enhancing the grammatical accuracy of EFL learners, only a few studies have explored the perspectives of EFL teachers regarding Formulaic-oriented Witten Corrective Feedback (FWCF) in EFL settings. Using a mixed-method approach, this interpretive exploratory study sought to understand the attitudes of Iranian EFL teachers toward FWCF. The analyses were based on quantitative data from a 13-item anonymous bespoke online survey, qualitative data from semi-structured interviews, and an open-ended question at the end of the survey. EFL teachers (n =137) responded to the online survey, and 7 participants participated in semi-structured interviews. The findings indicated that female teachers' favorable opinions about the effectiveness of WCF for improving EFL learners' writing performance resulted from their belief that the learners' capacity to use more formal and courteous language in their writing assignments was positively impacted by using these formulaic sequences. Moreover, the findings demonstrated that EFL teachers preferred direct WCF methods over indirect tactics. The most essential component that affected teachers' practices in the classroom was training designed to change their perspective of the valuelessness of WCF. The teachers' lack of satisfactory understanding of formulaic sequences stemmed from their lack of information. In addition, teachers' hesitancy to use them in the lower proficiency levels emanated from their misconceptions of their uselessness in the language learners' writing tasks.

This investigation aimed to examine the impact of spaced and massed education on the reading comprehension and vocabulary gain of Iranian EFL students. The researcher selected 150 Iranian participants out of 300 based on their enactment in the Oxford Quick Placement Test (OQPT). The selected medium participants were unsystematically assigned into two empirical groupings (spacing and massed) and one control group. The participants' reading comprehension and vocabulary knowledge in English were estimated using a pre-test. Three groups were provided with instruction on reading skills by English texts and new words from American English File 3. The massed group received a 90-minute session for each text, whereas the spaced group received three 30-minute sessions; the first session lasted 30 minutes, followed by two more sessions, each lasting 30 minutes, scheduled two days apart. Behind the teaching, a reading and vocabulary post-test post-test were distributed to the three classes. The results of data analysis utilizing independent samples t-tests and one-way ANOVA showed a considerable distinction between the post-tests of the spaced and massed groups compared to the control group. The findings demonstrate that the spaced grouping, which followed the specific recommended steps in their community, outperformed the massed and control groups (p < .05). This has consequential implications for English instructors, learners, and curriculum developers.

Self-reflection as a crucial human activity involves assessing experiences and developing strategies to tackle challenges in language instruction and acquisition. It can be pursued through several methods. This study seeks to implement scenario-based assessment (SBA) model and dialogue journal writing (DJW) in an entire process to examine their impact on enhancing the writing self-reflection strategies of Iranian EFL learners. To achieve this objective, 60 EFL learners were selected through convenience sampling. These participants were then randomly divided into two experimental groups and one control group. The first experimental group underwent treatment using a SBA model, while the second experimental group followed the requirements of treatment through a DJW model. The control group, on the other hand, received instruction using a traditional teacher-centered method. Both the experimental groups and the control group underwent pre-test and post-test assessments to evaluate their writing performance. The gathered data were analyzed using MANCOVA and the findings revealed that the SBA group outperformed the DJW and control groups in terms of improving their writing self-reflection strategies.This study's results offer more evidence to show the positive impact of using a SBA design on the writing self-reflection skills of Iranian EFL learners as a whole. The study showed that the SBA approach had a greater impact on improving engagement in self-reflection and insight. The findings of this study suggest that SBA can generate higher levels of assistance and function to create a successful pedagogical tool as well as an assessment device for classroom teachers, experts, and parties involved.
