Do I need to know how to code?

No. Describe what you want to teach in your own words and TutorFlow writes both the model and the code. Changing it works the same way: say what you want different and it is rebuilt.

What do learners need to open one?

A browser and the link you shared. A simulation is a self-contained web page, so there is nothing to install and no plugin to enable. Mouse and touch both work, so a classroom tablet or a phone is fine.

How is this different from a game?

A game has winning, losing and a score. A simulation has none of them. A learner changes values and reads what happens, which is what makes it the right tool for working a principle out.

How do you know the maths is right?

TutorFlow runs the simulation and drives every control to both ends of its range to check the screen really responds. That check confirms it works; it does not judge whether the subject or the difficulty suits your class, so open it once yourself before you share it.

Can I change it after it is built?

Yes. In the chat beside the simulation, write something like "widen the rate range" or "add an average line to the chart". Every version is kept and you can go back to an earlier one at any time.

TutorFlow simulation builder

Turn one sentence into a simulation your learners work out for themselves.

Say what you want them to discover and TutorFlow plans the model it will compute. Approve the plan and you get a page they explore by changing its values.

What does TutorFlow solve here?

Explain a principle in words and learners write it down. Let them change the numbers themselves and they work it out. That used to mean somebody had to build a simulation, which usually meant nobody did. TutorFlow takes one line about what you want to teach and builds a web page that really runs the calculation. Nothing to install, and a single link opens it on a classroom tablet.

A page that computes, not one that describes

Change a value and it recalculates on the spot, so the picture and the numbers move together. Nothing here is a prepared screen being flipped.

Run by TutorFlow before it reaches you

TutorFlow moves every control from one end of its range to the other and checks the picture really changes. A version whose sliders move and whose drawing does not is rebuilt.

Changes you ask for in words

Write "widen the rate slider to 20%" and the simulation is rebuilt. Every version is kept, so you can always go back.

Three simulations, built the way yours will be

Each started from one sentence a teacher wrote. Change the values here, exactly as a learner would.

The period of a spring

Change the mass and the spring constant and watch what happens to the period. The measured period is shown alongside.

Simple against compound interest

Move the principal, the rate and the term, and see exactly where the two curves start to part.

Comparisons a sort makes

Grow the array and count for yourself how the number of comparisons grows with it.

None of this was hand-coded. TutorFlow planned the model, wrote the maths, ran it, and published it.

What goes into a TutorFlow simulation

Three things separate a page that merely looks plausible from one you can teach with.

Read what it computes, and change it

Before anything is built, TutorFlow writes the plan. Which quantities it tracks and how they relate takes a minute to read, and anything that does not suit your class can be fixed right there.

The quantities tracked and the rule that advances them, yours to edit
Every control with its range, its starting value, and what moving it does
The questions a learner has to work out for themselves

T = 2π √(m ⁄ k)

Every control is checked against the picture

A simulation whose numbers change while the drawing stays still is worse than none. So on every build TutorFlow moves each control from one end of its range to the other and checks the screen actually changes.

A real run that drives every control to both ends of its range
A version whose picture does not move is rebuilt, not shipped
Starting values chosen so the effect is visible the moment it opens

Something to work out, not something to read

Every simulation carries questions a learner can only answer by moving the controls. Copying a number off the screen will not do it.

Inquiry questions that need the controls to answer
The relationship shown as a formula next to the numbers
Version history, so a change asked for in words is never one-way

One sentence to a working simulation, in three steps

1
Describe the principle
Say what you would like learners to work out. One principle they can find by changing values is enough.
2
Approve the plan
Read what it will compute and what can be changed, fix anything that does not suit your class, then build. It takes a few minutes.
3
Share the link
Send learners the link and it opens in their browser. Mouse and touch both work.

Who is TutorFlow's simulation builder for?

Programming courses

For teachers tired of describing in words how an algorithm behaves as the data grows.

Finance and business training

For subjects like compounding or break-even, where the feel for it only comes from moving the numbers.

Corporate training

For L&D teams who want people to try a decision and see where it leads.

Maths and science classes

For teachers who would rather show where a formula comes from before anyone memorises it.
