No-Prep Sub Plans for Digitalisation and AI in the World of Work

Writing sub plans for a business and CTE class is its own special headache: the substitute may know nothing about the subject, the technology, or your students, and you are often writing the plan at 6 a.m. with a fever. The lesson below is genuinely no-prep—it needs no logins, no printing beyond one page, and no prior knowledge from the adult in the room. It draws its content from Digitalisation and AI in the World of Work, but the whole thing runs from written instructions any substitute can read aloud. Copy it into your sub folder and forget about it until you need it.

What to leave on the desk

Set out one printed instruction sheet per pair and a stack of scrap paper. That is the entire materials list. The board should carry the day's driving question: Which jobs will digitalization and AI change, and how should workers respond? Everything else lives in the student instructions, so the substitute's only job is timekeeping and circulation.

The lesson, minute by minute

Give the substitute this exact schedule so the period runs itself:

1. 0–5 min — Settle and read: students copy the driving question and jot one job they think a computer could do today.
2. 5–15 min — Solo brainstorm: each student lists three tasks in a chosen career that AI might automate and three that still need a human.
3. 15–30 min — Pair and compare: partners merge lists and argue out any disagreements, marking tasks “automate,” “assist,” or “human-only.”
4. 30–45 min — Group ranking: pairs join into fours and rank the top three skills a worker will need in an automated workplace.
5. 45–55 min — Share out: each four reads its top skill; the substitute lists them on the board.
6. 55–60 min — Exit ticket: students write one sentence on how they would future-proof their own career.

No specialist knowledge is required to run any step—the thinking belongs entirely to the students.

Student-facing instructions

Print these verbatim so students can self-launch even if the substitute is stretched: “Today you are workforce analysts. Pick a career you might want. List the daily tasks. Decide which a computer could do, which it could help with, and which only a person can do. Be ready to defend your choices—a good analyst explains the why, not just the what.” Because the task is open, it self-differentiates: every student can enter, and the strongest push into genuine analysis. The reasoning also connects to workplace habits explored in Time Management and Study Methods for Apprentices, so nothing here is off-syllabus.

What you collect the next day

Ask the substitute to gather the exit tickets and note any pair that finished early. When you return, those tickets are a ready-made formative snapshot: you will see who grasps that adaptability, not just technical skill, is the real hedge against automation. The group rankings also make a perfect warm-up for your next lesson—or a springboard into teamwork content such as Conflict and Team Management in Training, since deciding what only humans can do inevitably raises how humans work together. A sub plan that produces usable evidence is a sub plan that did not waste a day.
