Why bigger samples are steadier
Drag the sample size and watch averages settle.
Supply and demand
Shift demand and predict the new price.
Try it
Takes about 1 minute.
The problem
Students memorize the diagram but can't predict what happens when something changes.
Who it's for
First-year economics modules, business schools
Before and after
See how we make a difference
Before
As it usually is
- A static textbook diagram.
- A worked example to read.
After
Redesigned
- Change 1: A model students move themselves.
- Change 2: The old result stays in gray for comparison.
- Change 3: A prediction before the answer.
- Reason for change 1: Moving the curve builds the idea, not just the picture.
- Reason for change 2: Before and after sit side by side, so the change is easy to see.
- Reason for change 3: Guessing first makes the answer stick.
How we'd build this for you
A model learners move themselves
This activity is one example of a pattern that works in almost any subject. Here's how the same idea could look in yours.
- FinanceMove the interest rate and watch monthly loan repayments change.
- Public healthChange vaccination rates and see how far an outbreak spreads.
- Climate scienceAdjust emissions and watch the temperature curve respond.
- BusinessChange the price of a product and see the effect on sales and profit.
- Supply chainsDelay a shipment and watch stock levels run down.
We build it with your subject experts and your own examples, in your learning platform. Every piece works on phones, by keyboard and with screen readers.
