task-based instruction

While many English language learning textbooks provide exercises on the difference between present simple and present progressive tenses, they often lack meticulous explanations regarding their meaning and contextual usage. Having been inspired by cognitive linguistic studies on English present tense and the theory of Cognitive Grammar, an empirical study was devised to incorporate the elements of cognitive linguistics analysis of English present progressive tense into EFL grammar teaching material. This quasi-experimental study included 53 adult EFL learners being homogenized in terms of their English proficiency based on their scores on Quick Oxford Placement Test, and randomly assigned to three groups. The course of instruction lasted for three weeks during which the groups met 6 times. The cognitive group (N = 18) received cognitive linguistic explanations followed by examples indicating inherited epistemic contingency in English present progressive tense (including, current ongoingness, historical present progressive, future present progressive, temporary validity, duration, iteration, repetition, and modality) and structural construal indicated by present simple. The task-based group (N = 16) received conscious-raising tasks lacking cognitive linguistic explanations. The control group (N = 19) did not receive any explicit instruction. Pretest and posttest scores were used to measure the effectiveness of the types of instruction. The results of paired samples t-test and one-way ANOVA revealed that the cognitive group outperformed the task-based group and the control group showing a higher level of construing usage context of present simple and present progressive tense.

Language learning platforms or channels have always been a challenge and source of inspiration for the respective SLA researchers. The two widely used channels are learning exercises and tasks, which have received much research but which is more effective in developing language skills (listening here), is still controversial. Additionally, learners' features, including their learning styles, might be either an effective or an affected factor in applying either channel. To shed light on both problems, this experimental research employing 55 conveniently sampled Iranian intermediate EFL learners categorized into experimental and control groups was conducted. The experimental groups exposed to both pre-and post-tests received task- and exercise-based listening instructions separately for ten sessions. Their perceptual learning styles were also measured after the interventions. The respective parametric statistical analysis (i.e., independent-samples t-test) showed that both groups performed roughly equally in the post-test, and there was statistically no significant difference between intervention types. ANCOVA was run concerning each sub-style to address the status of the learning styles. Similarly, the relationship between listening ability and method type showed no statistically significant differences, regardless of whether the effectiveness of either treatment was natural. Both listening activities worked efficiently to enhance learners' listening comprehension abilities. Statistically speaking, the results confirmed the non-significantly differentiating effects of both independent variables on developing listening skills and modifying learning styles. The findings are more challenging rather than concluding, which, while bearing specific pedagogical insights, motivates further research.

This study aimed to investigate the impact of flipped task-based instruction (TBI) on EFL learners' speaking skill and attitude towards this mode of instruction. Four intact classes consisting of 60 EFL learners were assigned to control and experimental groups. The data were collected by administering two speaking tests and a questionnaire investigating the participants' beliefs about flipped TBI. The scores of the participants on the two speaking tests were statistically analyzed through an ANCOVA. The results showed that flipped TBI has a positive impact on EFL learners' speaking skill. In addition, the analysis conducted on the participants' scores on the attitude questionnaire revealed that the attitudes of the participants in the experimental groups towards flipped TBI changed positively. The findings of this study can be theoretically and practically employed by EFL teachers and applied linguists.

The purpose of this study is to investigate the effects of task-based instruction (TBI) and project-based instruction (PBI) on the improvement of EFL learners' referential and expressive writing performance. To accomplish this objective, 60 students majoring in English translation participated in Oxford Quick Placement Test (OQPT), but out of them 50 students were selected as the members of a homogeneous sample. Then, they were assigned into two experimental groups. They were exposed to IELTS module task-based writing pre-test, treatment, and post-test, to assess the participants' writing performance. The participants in first experimental group received TBI to practice the referential and expressive types of writing, while those in the second group received PBI. The results showed that TBI and PBI affected the development of both referential and expressive writing among EFL learners. In addition, the results revealed that there was not any statistically significant difference between the effect of PBI and TBI on developing expressive and referential writings among EFL learners. The pedagogical implications of the study are discussed at the end of the paper.

L2/FL writing ability, which per se includes many different types, is considered a major skill in academic settings. However, little research has been done in this area and even less has focused on the effectiveness of task-based writing instruction on the two specific kinds; namely, referential writing and expressive writing. To this end, 60 English Translation sophomores of both genders were selected and divided into two classes after ensuring their homogeneity through the Quick Placement Test (OQPT). For the pre- and post-tests, the participants were required to take IELTS writing tests requiring referential and expressive types of writing. As for the treatment of the study, all participants were instructed based on the same content materials of advanced writing and a task-based framework. The results of the statistical analysis indicated significant improvements in the participants’ writing abilities in referential and expressive written tasks. Besides, the effectiveness of task-based writing techniques was approved in terms of referential and expressive types of language functions in the academic writing of Iranian EFL learners.

Although Task-Based Instruction (TBI) has received large attention on the part of English practitioners throughout the world, it seems that there is yet a huge gap between the Iranian EFL teachers’ perceptions and practices in implementing it in real classes. Hence, this study set out to unearth the possible sources of difficulties in using TBI in EFL classes. To meet the goals, a total of 120 male and female EFL teachers were selected through stratified random sampling from Iran language institute (ILI) branches in Tehran, Iran. After critically reviewing the literature and using a flow chart technique, a questionnaire including 20 items was developed, piloted, and distributed among the participants. Then, the collected data were analyzed through the Confirmatory Factor Analysis (CFA). Results indicated that three main factors, namely lack of appropriate assessment methods, cultural difference, and efficacy of the method received the utmost significance from the EFL teachers’ perspectives that have led to not using TBI. In the end, the implications of the findings were discussed for different stakeholders.
