Speaking and Interaction: Rehearsed and Unrehearsed Exchanges
Welcome! Speaking in an additional language can sometimes feel intimidating, especially when you have to speak on the spot. In this chapter, we explore how spoken communication works under Criterion C: Speaking in the IB Middle Years Programme (MYP). You will discover the difference between rehearsed and unrehearsed exchanges, how your speaking skills grow across the MYP phases, and practical strategies to help you speak with confidence in any conversation.
Note: In other chapters, you explore how to present using visual prompts in "Presenting and responding to a multimodal stimulus", handle transactional situations in "Everyday transactions and role play", and discuss complex themes in "Discussing topics of personal and global significance". Here, our focus is strictly on mastering the dynamic between prepared speech and spontaneous conversation.
What Are Rehearsed and Unrehearsed Exchanges?
To understand Criterion C, imagine learning to play basketball. First, you practice specific drills and set plays with your team until you know them inside out. That is your rehearsed practice. But once the whistle blows in a real game, you must react instantly to where the opposing players run and how the ball bounces. That is the unrehearsed reality. Both skills are essential!
1. Rehearsed Exchanges
A rehearsed exchange is a spoken interaction that you have had time to plan, draft, practice, or anticipate in advance.
• What it looks like: Preparing an interview with a partner, practicing a structured role-play, or anticipating likely questions after a presentation and preparing clear answers.
• Why it matters: It allows you to build confidence, organize your ideas logically, check your word choice, and practice clear pronunciation and intonation.
• Common misconception: Rehearsed does not mean reciting a memorized script like a robot! Even in a rehearsed exchange, natural eye contact, pausing, and responsive body language are essential.
2. Unrehearsed Exchanges
An unrehearsed exchange is spontaneous communication. It happens in real time when you hear something you did not anticipate and must formulate a meaningful response on the spot.
• What it looks like: A classmate asks an unexpected follow-up question during a discussion, your teacher asks for your spontaneous opinion on a new topic, or a partner counters your viewpoint.
• Why it matters: Spontaneous interaction shows genuine language acquisition. It proves you can process spoken input, select language from memory, and express your thoughts without reading notes.
• Key takeaway: A rehearsed exchange gives you structure and preparation; an unrehearsed exchange tests your ability to think, react, and keep a real-life conversation moving forward.
The Criterion C Depth Ladder: How Expectations Progress
In the MYP, language learning is organized into six phases, grouped into three formal assessment levels: emergent (phases 1–2), capable (phases 3–4), and proficient (phases 5–6). You do not need to start at phase 1; your placement depends on your existing language experience.
Look at how the Criterion C requirements for interaction evolve as you move up the phases:
• Phase 1 (Emergent): You respond appropriately to simple short phrases and interact in simple and rehearsed exchanges using verbal and non-verbal language (such as gestures and nodding). You communicate basic ideas on everyday topics with a sense of audience.
• Phase 3 (Capable): You respond appropriately to spoken, written, and visual texts, and interact in both rehearsed and unrehearsed exchanges. You express ideas and feelings in familiar and some unfamiliar situations, communicating with a clear sense of audience and purpose.
• Phase 5 (Proficient): You engage effectively in both rehearsed and unrehearsed exchanges on topics of personal and global significance. You express ideas, opinions, and complex feelings across a wide range of situations, demonstrating sophisticated control of register, purpose, and style.
Did you know? In MYP Year 5, your final speaking assessment is an internally assessed, IB-moderated speaking examination marked out of 24 marks against Criterion C. Examiners listen specifically for your ability to maintain a natural conversation beyond your prepared remarks!
Building Success in Rehearsed Exchanges
When you are given time to prepare a spoken exchange, make the most of your planning time with these practical strategies:
• Plan ideas, not full scripts: Memorizing a full text word-for-word is dangerous. If you forget a single word, you might freeze. Instead, use bullet points, keywords, or mind maps that remind you of the key message.
• Prepare open-ended questions: A good exchange requires two-way interaction. If you only ask questions that require a yes or no answer, the conversation stops. Instead of asking "Do you like city life?", ask "What do you think is the biggest advantage of living in a large city?"
• Use non-verbal language: Communication is more than just words. Facial expressions, hand gestures, posture, and nodding demonstrate that you are actively listening to your partner.
• Focus on intonation and rhythm: In Criterion D, your spoken pronunciation and intonation are assessed alongside vocabulary and grammar. Rehearsal is your chance to practice where to place emphasis and where to pause for effect so that your speech sounds natural rather than flat.
Mastering the Unrehearsed Exchange: Spontaneous Strategies
What happens when your partner or teacher says something you did not prepare for? Don't worry if this feels challenging at first—every language learner experiences moments of hesitation. The secret is knowing how to handle those moments using interaction strategies.
Strategy 1: Active Listening and Processing
Before you can produce an unrehearsed response, you must interpret what you heard. Focus on the main message rather than trying to understand every single syllable. Listen for keywords, emotional tone, and whether the speaker is asking for an opinion, an explanation, or a choice.
Strategy 2: Buying Thinking Time (Fillers and Turn-Holding)
Native speakers rarely answer instantly; they use natural phrases to gather their thoughts. Instead of falling completely silent or switching to your home language, use English time-buying phrases:
• "That is an interesting question..."
• "Let me think about that for a moment..."
• "Well, looking at it from that perspective..."
• "To be completely honest, I hadn't thought about that before, but..."
Strategy 3: Requesting Clarification
If you genuinely did not understand what was said, asking for clarification is not a failure—it is an essential communication skill recognized in the MYP descriptors:
• "Could you please repeat that more slowly?"
• "Could you rephrase that? I want to make sure I understand."
• "Do you mean that...?" (Paraphrasing what you think you heard to check your understanding).
Strategy 4: Extending and Building the Exchange
Avoid one-word answers. A single "Yes" or "I agree" shuts down the conversation. Use the simple formula Answer + Reason + Follow-up:
• Answer: "I definitely agree with that idea."
• Reason: "...because local communities need more sustainable transport options to reduce pollution."
• Follow-up question or hand-over: "...What has been your experience with public transport where you live?"
• Key takeaway: In unrehearsed exchanges, fluent interaction does not mean perfection; it means keeping the flow going through clarification, time-buying phrases, and open-ended expansions.
Audience, Purpose, Register, and Style
As you progress from emergent to capable and proficient levels, Criterion C expects you to adapt your language dynamically to the social setting of the conversation.
• Audience: Who is listening to you? Are you conversing with a close friend, a classmate, a school principal, or an unfamiliar examiner? Your choice of words and level of formality must reflect who you are talking to.
• Purpose: Why are you talking? Is your purpose to persuade, inform, resolve a conflict, share an emotional reaction, or collaborate on a shared task? Clarifying your purpose helps you choose the right sentence structures.
• Register: This refers to the degree of formality. In an informal peer exchange, casual phrasing ("What do you reckon?") is appropriate. In an academic or formal speaking assessment, a standard or formal register ("What is your view on this issue?") is expected.
• Style and Word Choice: At phase 5, you choose vocabulary with precision to convey nuanced opinions, subtle feelings, and perspectives on global topics.
Connecting to MYP Concepts
Your work with rehearsed and unrehearsed exchanges is guided by the overarching concepts of the Language Acquisition framework:
• Key Concept — Communication: Communication is a reciprocal process. It is not just about producing speech; it is about sending, receiving, interpreting, and responding to messages between two or more people.
• Key Concept — Connections: When you interact spontaneously, you make connections between your own experiences, your partner's opinions, and wider local or global contexts.
• Related Concept — Conventions: Conversations have unwritten rules, known as conventions. These include turn-taking (not interrupting rudely, but also not staying silent too long), polite disagreement, and appropriate greeting and closing phrases.
• Related Concept — Word Choice: Selecting the right word during a fast-moving, unrehearsed exchange allows your exact meaning to come across clearly without confusion.
• Related Concept — Idiom: Using natural expressions and idioms appropriate to the target language helps your unrehearsed speech sound authentic and fluent.
Common Mistakes and How to Avoid Them
• Mistake 1: Treating speaking like a silent reading exam. When interacting, silence breaks the exchange. Even if you do not know the exact word, use a synonym or describe the object or idea rather than stopping completely.
• Mistake 2: Dominating the conversation. An exchange is an interaction, not a monologue. If you speak for three minutes without allowing your partner to contribute, you are not demonstrating interactive communication skills.
• Mistake 3: Over-preparing a script for an oral exam. Teachers and examiners can tell immediately when a student is reciting memorized paragraphs. If the examiner interrupts with an unrehearsed question, memorized students often panic. Practice speaking from concise bullet points instead!
• Mistake 4: Giving up after a grammatical mistake. In Criterion C, your ability to communicate meaning, maintain interaction, and respond to your partner is what matters most. If you make a slip, correct yourself quickly if you can, or simply keep going. Never freeze over a minor error.
Quick Review
• Criterion C assesses your ability to speak and interact in response to multimodal texts across familiar, unfamiliar, personal, and global topics.
• Rehearsed exchanges involve planned, structured communication where you organize thoughts, prepare questions, and refine your delivery.
• Unrehearsed exchanges require real-time spontaneous responses, active listening, and interactive strategies like turn-holding and requesting clarification.
• Phase progression: Phase 1 focuses on simple, rehearsed interactions with an awareness of audience; Phase 3 develops rehearsed and unrehearsed exchanges with audience and purpose; Phase 5 commands sophisticated, spontaneous exchanges with nuanced register, purpose, and style.
• Conversation flow: Keep exchanges active by answering with reasons, building on your partner's points, and asking engaging follow-up questions.
