Activity types, explained

Every activity in the Jotter library carries a type badge. Here's what each one means: how it runs, how long it takes, and what you'll actually be doing.

The types

Interactive case

In session or independently · typically 15–25 minutes

A realistic scenario you work through by making judgements: read the situation, weigh the evidence, decide, then see the model reasoning and where yours differed. Cases put you inside a decision rather than describing one to you.

For example: Theranos through the dark pyramid: classify what really enabled a corporate scandal, layer by layer.

Reflection

In your own time · typically 5–20 minutes

A short, private reflection in your own words: you work one honest question or experience through at your own pace. Nothing is assessed, and your notes stay on your device for you to build on and lift into your own writing later.

For example: My learning, honestly: walk one real, recent failure of your own through four honest questions.

Decision exercise

Run live in session · typically 20–60 minutes

The most substantial format: work one major decision stage by stage with real numbers. Some run like a board pack: you're the analyst building the case, with feedback at every stage. Others branch live: the whole room commits a choice, sees how the room split, and lives with the consequences the majority chose (unless your academic takes you down the road not taken). Ends with a debrief of the path you took.

For example: Board decision: cost-saving (build the case for a £4m operating model change); or The cash crunch (a customer wants better terms, the cash tightens, and every choice the room makes writes the next chapter).

Walkthrough

In session or independently · typically 10–15 minutes

A guided build-up of one concept, step by step, with quick checks along the way so you know it's landing. Walkthroughs start from something you already understand and only add names to ideas once you've used them.

For example: Back to basics: what you own, what you owe (the accounting equation built from a £100 bike, then a cake stall, then a house and mortgage).

Quiz

In session or independently · typically 10–15 minutes

A set of five to nine questions with teaching feedback on every answer: not just right or wrong, but why, and what to watch for next time. Quizzes are unassessed and retryable; many are designed to run as a whole-group wrap-up at the end of a taught day.

For example: Systems thinking essentials: eight questions that check the whole toolkit, from feedback loops to leverage points.

Glossary

Whenever you need it

A quick-reference A–Z of the key terms for a subject, in plain English. The same definitions power the dotted-underline hover explanations you'll see inside activities. Hover any underlined term and its meaning pops up.

For example: Finance glossary: from accruals to working capital in one page.

Tool

Whenever you need it

A standalone helper you can use over and over: a calculator or interactive aid rather than a task with questions.

For example: The swing calculator: see how a profit swings to a loss as the drivers move.

Guide

Whenever you need it

A practical look-up guide you return to when you need it, rather than work through once: how-tos, checklists and one-page maps.

For example: A guide to APA 7th referencing: how to cite anything, with worked examples.

What they all share

Whatever the badge, every activity works the same way underneath: you commit an answer before the model appears, every answer gets feedback that teaches rather than just scores, and each activity ends with one big idea worth carrying forward. The thinking behind that design is set out in our approach to learning.
