task-based teaching

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-based language teaching is considered an effective way to achieve a harmony between grammar and communication. The present study investigates two different ways of teaching modal verbs: task-based versus traditional approaches. To this purpose, an Oxford Placement Test was administered to select 40 homogeneous participants out of a larger population who took this test. The selected participants were randomly divided into experimental and control groups of 20 students each. Those in the experimental group attended an English class six days a week, practicing grammar through tasked-based approach, while the control group did not receive any task-based work. The OPT was administered at the end of the semester again to see which group could do modal verbs better. A final test of modal verb tasks was also administered at the end of the study to see if all the learners have improved in using modal verbs in the same way/at the same amount through task-based language teaching. The results of this study indicated that there is a statistically significant difference between the experimental group and the control group, meaning that teaching modal verbs through task-based approaches has been more effective than teaching them in traditional ways. It was also revealed that the modal verb can was improved much more, while have to and must were improved less. The results of the study may have a significant implication for teaching modal verbs in particular and language learning in general.
