Brainstorming

The rapid generation of ideas without evaluation or judgement, used in ELT as a pre-task, pre-writing, or pre-speaking stage. Brainstorming activates schemata (background knowledge) and lexis, priming learners for the main activity by bringing relevant knowledge and language to the surface.

Core Principle

The defining feature of brainstorming is deferred judgement: all ideas are accepted during the generation phase. Evaluation comes later. This principle, originating with Osborn (1953), removes the self-censoring that inhibits participation — particularly important in language classrooms where learners may hesitate to speak for fear of making errors.

Procedure

1. Set the topic: Teacher states the topic or question clearly
2. Generate: Learners produce ideas rapidly — individually, in pairs, or as a class. All ideas are recorded without comment.
3. Organise (optional): Ideas are grouped, categorised, or prioritised
4. Use: Ideas feed into the main activity (writing plan, discussion, task)

Formats

Format	Description	Best for
Individual	Silent writing of ideas	Ensuring all learners contribute; introverts
Pair/group	Collaborative idea generation	Building on each other's ideas; energy
Whole class	Teacher elicits and boards ideas	Quick activation; vocabulary pooling
Mind map	Central topic with branching associations	Visual organisation; Graphic Organizer
Word cloud	Rapid word association	Vocabulary activation

Applications in ELT

• Pre-writing: Generate ideas for an essay or paragraph before planning (essential for exam preparation)
• Pre-speaking: Activate vocabulary and ideas before a discussion or presentation
• Pre-reading/listening: Top-down Processing — activate relevant schemata before engaging with a text
• Vocabulary review: What words do you know related to X?
• Lead-in/warmer: Engage learners with a topic at the start of a lesson (see Warmers and Coolers)

Why It Works

• Activates schemata: Brings background knowledge into working memory, improving subsequent comprehension
• Activates lexis: Primes relevant vocabulary, making it available for production
• Reduces blank-page anxiety: Particularly important for writing tasks — learners who brainstorm produce more content
• Inclusive: The "no judgement" rule encourages contributions from all learners, including weaker ones
• Flexible: Works at any level, with any topic, in any time frame

Design Considerations

• Set a time limit (2–5 minutes) to maintain energy and prevent over-thinking
• Accept all contributions — correcting or rejecting ideas during brainstorming kills participation
• Visual recording (board, poster, shared document) makes ideas tangible and reusable
• Always follow brainstorming with a purpose — if ideas go nowhere, learners stop taking it seriously
