task difficulty

This article reports on the findings of a study that investigated the impact of manipulating task performance conditions on listening task performance by learners of English as a foreign language (EFL). The study was designed to explore the effects of changing complexity dimensions on listening task performance and to achieve two aims: to see how listening comprehension task performance was affected and to investigate possible overlaps between EFL learners’ perceptions of task difficulty and hypothesized task complexity. A purposive sample of 54 first-year EFL learners randomly assigned to two parallel conversation classes in an English department of a major public university participated in the study and performed listening tasks in a language lab. The instruments used for data collection were seven tasks taken from a TOEFL Test Preparation Kit, each followed by listening comprehension questions and an item on the participants’ personal perception of the difficulty of the task. During counter-balanced administrations, the tasks were manipulated for one of the four dimensions of task difficulty (adequacy, immediacy, perspective, and prior knowledge). The resulting data included the participants’ perception of difficulty as well as their performance scores under less complex and more complex conditions. One-sample T-test and correlation analyses of the data revealed that for all of the four complexity dimensions, the hypothesized less complex task condition led to better learner performance. The correlation between learner-assigned difficulty score for the task at hand and theoretical task complexity level was significant only for the immediacy dimension (r=-0.67, p<.05). The results offer support for task complexity frameworks, raise doubts about learners’ perceptions of tasks, and imply possibilities for task manipulation in language learning contexts.

Task difficulty across different macro-genres continues to remain among less attended areas in second language development studies. This study examined the correlation between task difficulty across the descriptive, narrative, argumentative, and expository macro-genres. The three components of task difficulty (i.e., code complexity, cognitive complexity, and communicative stress) were also compared in the four macro-genres. The design included the administration of short reading texts with comparable length and readability indices based on the four macro-genres followed by task difficulty questionnaire. The macro-genre-based reading textsalong with the task difficulty questionnaire were administered to 50 EFL students in the University ofLorestan, Iran. Task difficulty questionnaire explored the learners’ perceptions of task difficulty in the code complexity, cognitive complexity, and communicative stress domains. The results revealed that there were no significant differences among the task difficulty components in the four macro-genre-based text types. The findings also showed that there was no significant correlation between task difficulty of each macro-genre with those of the other genres except thoseofthe narrative and expository genres.The findings hold implications for the use of macro-genres with different task difficulty indices in task-oriented programs, teacher training, and testing.

This study investigated the quality of metacognition at its inter-individual level, i.e., socially-shared metacognition, across two collaborative writing tasks of different difficulty levels among a cohort of Iranian EFL learners. Moreover, it examined the correlation between the individual and the social modes of metacognition in writing. The analysis of think-aloud protocols of a number of pre-intermediate and advanced EFL learners revealed instances of episodes in which peers used metacognitive activities at pair level. Besides, comparing think-aloud protocols of tasks indicated more frequent and longer use of socially-shared metacognitive episodes in more difficult writing tasks. The study also found high correlation between the social mode of metacognition in L2 writing and learners’ individual metacognition. The pedagogical implications include the provision of learning opportunities in which learners are challenged to exploit metacognitive strategies, such as planning, monitoring, and self-evaluating.

The present study was an attempt to provide a psycholinguistic account of cognitive processes underlying responding and questioning. It also strived to identify the potential differences between responding and questioning cognitive processes in Target Language Use Situation tasks. To accomplish the objectives, 65 Iranian general IELTS applicants from two foreign language learning institutes in Shiraz, with two different language proficiency levels (intermediate and advanced), were randomly selected. They were administered a normal responding and a reverse questioning IELTS oral tasks. Two seven-point Likert scale questionnaires were also used to measure the task difficulty and mental effort that the applicants perceived while doing the tasks. Additionally, the applicants’ recorded voices in tasks were transcribed and analyzed to assess the number of grammatical errors and pause lengths. The analysis of the numerical data through descriptive statistics and paired-samples t-tests indicated that, in general, the cognitive processes underlying oral responding and questioning are significantly different in terms of mental effort, task difficulty, length of pauses, and the number of grammatical errors. More specifically, the results suggested that the applicants took more mental effort and perceived more task difficulty while constructing the questions for given responses irrespective of their proficiency levels. Both groups also paused significantly longer and committed significantly more grammatical errors when completing the questioning tasks. The paper discusses the study implications for second language teachers and assessors.

Regardless of the appreciation of language learners’ achievement in task-based language teaching, not much has been hinged upon learners’ perception and reception of various elements. This study examined task complexity and modality effects on Iranian EFL learners’ comprehension of task difficulty, competencies, and difficulty-skill balance as well as the learners’ task experience. The Flow Outlook features were also applied to investigate how difficulty-skill balance anticipated flow experience. Via a repeated-measures design, and with a focus on task complexity (simple vs. complex) and task modality (written vs. spoken), 49 EFL learners carried out four argumentative tasks (two simple written and spoken vs. two complex written and spoken tasks); then, they ticked the flow questionnaire to gauge their perception of task difficulty, competence, and task experience. Repeated-measures MANOVA revealed although task complexity influenced task difficulty and difficulty-skill balance significantly, the skill was not affected significantly; task modality influenced task difficulty and skill significantly while difficulty-skill balance received no significant effect. The follow-up post hoc test indicated that complexity and modality significantly influenced flow, attention, and control, but not interest. Linear regression revealed difficulty-skill balance was a predictor for learners’ flow experience for both writing tasks and simple speaking task but not for complex speaking tasks. Pedagogically, the findings of this research may have some implications for English language teachers, learners, and materials developers.
