Task-based Language Learning ( TBLL )

Task-based Language Learning ( TBLL )

Task-based language learning (TBLL), also known as task-based language teaching (TBLT) or task-based instruction (TBI) focuses on the use of authentic language and on asking students to do meaningful tasks using the target language. Such tasks can include visiting a doctor, conducting an interview, or calling customer service for help. Assessment is primarily based on task outcome (in other words the appropriate completion of real world tasks) rather than on accuracy of prescribed language forms. This makes TBLL especially popular for developing target language fluency and student confidence. As such TBLL can be considered a branch of Communicative Language Teaching (CLT).
In practice, The core of the lesson or project is, as the name suggests, the task. Teachers and curriculum developers should bear in mind that any attention to form, i.e. grammar or vocabulary, increases the likelihood that learners may be distracted from the task itself and become preoccupied with detecting and correcting errors and/or looking up language in dictionaries and grammar references. Although there may be several effective frameworks for creating a task-based learning lesson.

Types of task in TBLL :

According to N. S. Prabhu, there are three main categories of task; information-gap, reasoning-gap, and opinion-gap.

Information-gap activity . which involves a transfer of given information from one person to another – or from one form to another, or from one place to another – generally calling for the decoding or encoding of information from or into language. One example is pair work in which each member of the pair has a part of the total information (for example an incomplete picture) and attempts to convey it verbally to the other. Another example is completing a tabular representation with information available in a given piece of text. The activity often involves selection of relevant information as well, and learners may have to meet criteria of completeness and correctness in making the transfer.

Reasoning gap . Reasoning-gap activity, which involves deriving some new information from given information through processes of inference, deduction, practical reasoning, or a perception of relationships or patterns. One example is working out a teacher’s timetable on the basis of given class timetables. Another is deciding what course of action is best (for example cheapest or quickest) for a given purpose and within given constraints. The activity necessarily involves comprehending and conveying information, as in information-gap activity, but the information Teaching to be conveyed is not identical with that initially comprehended. There is a piece of reasoning which connects the two.

Opinion gap . Opinion-gap activity, which involves identifying and articulat-ing a personal preference, feeling, or attitude in response to a given situation. One example is story completion; another is taking part in the discussion of a social issue. The activity may involve using factual information and formulating arguments to justify one’s opinion, but there is no objective procedure for demonstrating outcomes as right or wrong, and no reason to expect the same outcome from different individuals or on different occasions.

If learners have created tangible linguistic products, e.g. text, montage, presentation, audio or video recording, learners can review each others' work and offer constructive feedback. If a task is set to extend over longer periods of time, e.g. weeks, and includes iterative cycles of constructive activity followed by review, TBLL can be seen as analogous to Project-based learning.
