Interactive Debates

Overview

In this lesson, students practise spontaneous spoken English through a structured debate, applying grammar skills and persuasive language in a real-time discussion context. This is lesson 7 of 8 in the "Mastering English Speaking Skills" unit.

Learning intentions

• Students will understand how to construct and deliver a coherent spoken argument.
• Students will apply accurate grammar and a range of vocabulary in spontaneous speech.
• Students will develop active listening and the ability to respond to opposing viewpoints.
• Students will reflect on their own speaking performance using IB-aligned criteria.

Success criteria

• I can present a clear point of view with supporting evidence or reasoning.
• I can use appropriate grammar, including complex sentence structures, in spoken responses.
• I can respond constructively to a counterargument without losing clarity or focus.
• I can reflect on my own speaking performance and identify one area for improvement.

Curriculum links

• IB DP Language A/B preparation — extended spoken interaction, register, and audience awareness

Lesson structure (60 minutes)

0–5 min | Warm-up: Agree or Disagree Display three bold statements on the board (e.g., "Social media does more harm than good"). The student reads each one and gives an instant spoken response — agree, disagree, or partly agree — with one reason. This activates prior speaking skills and builds confidence for the debate ahead.

5–15 min | Debate Preparation Assign the student a debate motion relevant to Year 11 interests, such as "This house believes that schools should ban smartphones entirely." Assign a side (for or against) and allow ten minutes to plan three key arguments, using sentence starters and grammar prompts on a provided scaffold sheet. Encourage the use of conditionals, modal verbs, and discourse markers (e.g., "Furthermore," "On the other hand," "It could be argued that…").

15–30 min | Structured Debate (Round 1) Run a formal debate format: the student presents their opening argument (3–4 minutes), then the teacher takes the opposing side and presents a counter-argument. The student must respond spontaneously with a rebuttal. Emphasise that the goal is fluency and coherent argumentation, not perfection. The teacher notes grammar use, vocabulary range, and confidence without interrupting.

30–40 min | Reflective Pause and Peer Review The teacher shares brief oral feedback on strengths observed during Round 1, framing it around IB assessment criteria for spoken language: accuracy, fluency, range of expression, and message clarity. The student self-assesses using a short written prompt: "What went well? What would I change?" This metacognitive step aligns with IB's emphasis on learner reflection.

40–52 min | Debate (Round 2 — Switched Sides) The student now argues the opposite position on the same motion. This challenges them to think critically, see multiple perspectives, and adapt language flexibly — all core IB learner profile attributes. The teacher continues in the opposing role. This round tends to produce more confident, nuanced speech as the student has warmed up.

52–60 min | Debrief and Target Setting Discuss the debate as a whole. Ask the student to identify: one grammar structure they used well, one they struggled with, and one speaking strategy to carry forward into the final lesson. Record targets in the student's speaking log or exercise book. Briefly preview lesson 8 — the assessed speaking task — so the student understands what to prepare.

Resources

• Debate motion written on the board or printed card
• Scaffold sheet with sentence starters, discourse markers, and grammar prompts (conditionals, modal verbs, complex clauses)
• IB speaking assessment criteria summary (adapted for classroom use)
• Timer (phone or classroom clock)
• Student exercise book or speaking log for self-reflection notes
• Teacher observation notes sheet for formative tracking

Assessment

• Formative observation: the teacher tracks spoken grammar accuracy, vocabulary range, fluency, and ability to respond to counterarguments during both debate rounds.
• Self-assessment: the student completes a brief written reflection using guided prompts, identifying strengths and areas for development.
• Target setting: the student records one specific speaking goal to work towards in the final assessed lesson.

Differentiation

• Support: Provide the scaffold sheet with pre-written sentence starters and a word bank of useful debate phrases; allow slightly longer preparation time and prompt with guiding questions during rebuttals if the student stalls.
• Extension: Introduce more abstract or nuanced motions (e.g., ethical dilemmas or global issues); challenge the student to avoid using notes during Round 2 and to incorporate at least three varied grammatical structures consciously.
• EAL/SEN: Provide the debate motion and key vocabulary in advance so the student can pre-prepare familiar language; focus feedback on communicative effectiveness and confidence rather than grammatical precision alone; allow brief pauses without pressure to fill silence immediately.
• One-to-one context: Take full advantage of the individual setting by adapting the debate in real time to the student's interests and confidence level — this lesson works especially well as a genuine dialogue rather than a performative exercise.
