Mantle of the Expert

An extended fictional frame where students are cast as a team of experts (architects, scientists, curators, archaeologists) engaged in a mission for a client. Over one or several lessons, they work in role to solve a problem, using English as the work language throughout.

Dorothy Heathcote's approach, originating in UK drama education, now used in CLIL and project-based language teaching worldwide.

Procedure (multi-lesson example)

1. The commission (10 min): Teacher in role as the client. Good morning. You are an experienced team of museum designers. Our small museum has received a collection of artefacts and needs you to plan the exhibition.
2. Accept the mantle: students collectively adopt the expert role. They discuss their specialism, establish team norms.
3. Research phase: students investigate — read, interview, gather facts about the task (museum design, artefact handling, visitor flow).
4. Produce the deliverable: in English, the team produces a real-feeling artefact: a plan, a proposal, a report, a presentation.
5. Client review: the teacher in role reviews the work. Requests revisions. Students respond.
6. De-role and reflect: out of role, students discuss what they learned — subject content and language.

Why It Works

• English as the working language: students use language to do the task, not to practise it.
• Sustained engagement: projects unfold over hours or weeks; depth is possible.
• Expert stance raises register: students using expert-framing automatically reach for more formal, precise language.
• Multi-skill integration: reading, writing, speaking, listening all serve the work, not separate lessons.

Project Ideas

Mantle	Task
Museum curators	Design an exhibition on a given topic
Engineers	Build a sustainable bridge for a community
Restaurant owners	Create a menu, brand, and opening event
Journalists	Investigate a news story and publish
Architects	Design a new school wing
Scientists	Research a real environmental issue and present findings
Detectives	Solve a case using evidence provided
Doctors	Diagnose and present on a historical patient

Variations

• Short-form MoE: one-lesson compressed version. Commission → quick research → brief deliverable.
• Digital collaboration: team uses Padlet, Google Docs, Slack-style comms — all in English. Remote-friendly.
• Multi-team MoE: different teams have different specialities working on the same overall problem.
• Student-selected mantle: advanced classes pitch their own expertise and project.

Tips

• Commit fully to the frame. Address students by role title during the work. Drop it only for explicit out-of-role moments.
• The client (teacher in role) should have real needs — vague briefs produce vague work.
• Language emerges from the task, not from a list. Keep a running "words we needed today" list on the wall; students add to it.
• Not appropriate for every unit. Mantle of the Expert shines for complex, discussion-rich content; simple vocabulary practice doesn't need it.
