Secret roles, for a class

Classroom role-play and mock trials

A role-play works when students argue from a position they did not choose, holding information the rest of the room does not have. Here is how to cast one, what to put in each role's briefing, how to fit it into a lesson, and what to ask afterwards.

Why deal the roles secretly

Letting students pick means the confident ones take the judge and the lead counsel, and the quiet ones end up on the jury again. Dealing at random fixes that, and dealing privately does something more: a witness who is the only person holding their account has to be questioned properly, because nobody else in the room can fill the gap. Cross-examination only works when the lawyer genuinely does not know the answer.

Three shapes that work

Mock trial cast by class size

The core is six parts. From ten students, add a second witness on each side; everyone else is a juror. This is what the Mock trial preset writes for whatever class size you type.

StudentsCourtWitnessesJurors
6Judge, prosecutor, defence lawyer, defendant1 each side0 (the judge decides)
10Judge, prosecutor, defence lawyer, defendant2 each side2
16Judge, prosecutor, defence lawyer, defendant2 each side8
24Judge, prosecutor, defence lawyer, defendant2 each side16
30Judge, prosecutor, defence lawyer, defendant2 each side22

A jury of twenty is a lot of students with little to do. From about twenty, give some of them jobs by editing the list before you share it: a second counsel on each side, a court clerk who swears in witnesses and keeps the exhibits, a reporter who writes up the verdict. Or run two courtrooms with the same case and compare verdicts.

What goes in the note, and what goes in a briefing

The note is shown to everyone. Put the case there: what happened, who is accused of what, the one or two facts nobody disputes.

A briefing is shown only to the students dealt that role, under the role itself. It is where the private information lives:

Each briefing holds up to 600 characters, which is about five sentences. Roles with the same name share one briefing, so twelve jurors get the same instructions. The preset writes a short starter briefing for each part; replace them with your case.

Before you share the link: you can change the roles and briefings as often as you like until the first student joins. After that they lock, so the draw stays fair. Re-dealing everything unlocks them.

A 50-minute lesson

  1. Deal (5 minutes). Show the QR code from your organiser page on the projector. Students scan it, type their name, and read their role and briefing on their own phone. Your page shows who has joined and who has opened theirs.
  2. Prepare (10 minutes). Counsel meet their witnesses; jurors read the case; the judge reads the running order.
  3. Run it (25 minutes). Openings, each witness questioned and cross-examined, closings, the jury out.
  4. Debrief (10 minutes). Open the reveal-all link on your organiser page and put the full cast on the board.

Debrief questions

FAQ

Do students need an account or an app?

No. They open one link or scan the QR code and type their name. There is nothing to install and no email address to give.

How many students can one game take?

Up to 40 roles in one deal. For a bigger group, run two courtrooms with the same case, which also gives you two verdicts to compare.

Can students see each other's briefings?

No. Each student's role and briefing are on a private page at their own link. The shared link only shows how many roles have been dealt.

Can I change a role after I have shared the link?

Yes, until the first student joins. After that the roles lock so nobody's draw is changed under them. To change them later, re-deal everything and the class joins again.

What if a student is absent?

Their role stays undealt. Before anyone joins, remove a line; once the class has joined, reset a player from your organiser page to put their role back in the draw for someone else.
