What is the difference between a task and an exercise?

An exercise practises a predetermined form, and success means using that form correctly. A task has a non-linguistic outcome, such as a decision or a plan, and learners choose the language they need to reach it.

Do I need to give up my coursebook for TBLT?

No. Many teachers work with ‘task-supported’ teaching: they keep the coursebook and replace one or two exercises per unit with a full task. That is a realistic way to start.

How do I assess task-based work?

Assess the outcome (was the task achieved?) and the language (range, accuracy, interaction) separately. A short rubric with three or four criteria is enough for most tasks.

Is TBLT suitable for exam classes?

Yes, many exam formats include tasks such as writing an email or reaching an agreement in a speaking test. Task cycles prepare learners for exactly that, as long as you add exam-specific practice.

Task-Based Language Teaching with Examples

Task-based language teaching (TBLT) organises a lesson around a meaningful task, such as planning a trip, solving a problem or comparing offers, and lets language work grow out of that task. Learners first use whatever language they have to reach an outcome, then look closely at the language they needed. The task is the backbone of the lesson, not a reward at the end of a grammar unit.

What counts as a task?

Not every activity labelled “task” in a coursebook is one. In the research literature, a task is usually described by a set of criteria. In plain terms:

The focus is on meaning. Learners are mainly concerned with what they say, not which form they use.
There is a gap. Information, opinions or reasoning have to be exchanged or worked out.
Learners use their own resources. The teacher does not prescribe the structure in advance.
There is an outcome beyond language. A decision, a list, a plan, a map, a ranking.

Use this as a quick checklist. If one point is missing, you probably have a communicative exercise, which is useful, but not a task in the strict sense. See communicative language teaching for the broader framework.

The task cycle

A widely used framework, described by Jane Willis in the 1990s, divides a task-based lesson into three phases. You can adapt the timing, but the order matters.

Phase	What happens	Teacher’s role	Typical time (45 min)
Pre-task	Topic introduction, activate vocabulary, show a model or a short text	Set the scene, clarify the goal	5–8 min
Task	Learners do the task in pairs or groups	Monitor, do not correct	10–15 min
Planning	Groups prepare to report their outcome, polish their language	Language adviser	5–8 min
Report	Groups present or compare outcomes	Chair, comment on content	5–8 min
Language focus	Analysis and practice of language that came up	Lead, explain, practise	8–12 min

The planning phase is often skipped, but it is where much learning happens: learners want to sound good in front of the class, so they ask for words and check forms.

Three examples from the classroom

A2: The weekend plan

Input: three local events with times and prices (made-up or taken from a real event website). Task: in groups of three, agree on a plan for Saturday that suits everyone’s preferences (each learner has a role card with likes, dislikes and a budget). Outcome: a short timetable on a card. Language focus afterwards: suggestions and responses (“Why don’t we…?”, “I’d rather…”).

B1: The class survey

Task: groups design five questions on a topic (media use, sleep, free time), interview another group and summarise the results. Outcome: a simple chart and three sentences. Language focus: quantifiers and comparing (“most of us”, “more than half”).

B2: The problem-solving meeting

Input: an email from a fictional school asking for ideas to reduce litter in the playground, with constraints (budget, rules). Task: groups agree on three measures and rank them. Outcome: a reply email. Language focus: hedging and persuading, formal email conventions.

Each example could easily be extended into a project or linked to subject content, which is where TBLT meets CLIL.

Planning a task-based lesson

Start from the outcome. What should learners have at the end? Write it down in one sentence.
Check the gap. Does each learner need input from others?
Prepare input at the right level. A short text, a set of pictures, a role card.
Decide on language support. For lower levels, a small bank of phrases helps; for higher levels, hold back and see what emerges.
Plan the language focus loosely. You can predict some language, but leave room for what you hear.

Our step-by-step guide to lesson planning includes a planning grid that works well for task cycles.

Common worries, and how to handle them

“They will just speak their first language.” Shorter tasks, a clear product in the target language and a planning phase before the report reduce this. In mixed classes, multilingual groups help.

“Weaker learners get lost.” Give them a role that is achievable (timekeeper, note-taker) and more structured input. Our guide to differentiation has further ideas.

“The curriculum expects grammar.” The language-focus phase is grammar teaching, just placed after the need has arisen. You can plan which structure you want to target and choose a task that is likely to produce it.

How TBLT relates to the CEFR

The CEFR’s action-oriented approach describes learners as social agents carrying out tasks. TBLT gives you a practical lesson structure for that idea, and CEFR can-do descriptors can help you choose task outcomes at the right level.

A first step

Take one coursebook unit and find the speaking or writing activity at the end. Ask yourself: Is there a gap? Is there an outcome? If not, add both, put the activity at the start of the next lesson, and teach the language focus afterwards. That single change turns a familiar unit into a task-based sequence.
