Classroom & Teacher Guides
Calling on students by raised hand quietly rewards the same confident kids every time. A wheel of names fixes that with a visible, unbiased spin, and the research backs up why that matters.
Cold calling has been studied directly in college and K-12 settings, and the findings are more specific than "it's fairer":
A spinning wheel adds something a name-in-a-jar can't: the randomness is visible. Students watch the pointer land, so the pick reads as the wheel's decision, not the teacher's.
That's the "warm," non-punitive framing the research above points to.

Open the random student picker. Build your list either way:
The tool holds up to 100 entries on one wheel, which comfortably covers any single class roster.
If you teach the same group regularly, this is the only step you'll repeat often. Your color theme and list are saved with the wheel.
A plain list of names works, but small additions make the spin part of the lesson, not just a utility. The classroom tool page keeps this simple on purpose.
For the two features below that go beyond it, use the full editor on the wheelofnames.io homepage instead (it's the same wheel engine with more per-entry controls exposed):
Click the center SPIN button (or tap it on a touchscreen/interactive board). The wheel spins, slows, and highlights the winning name. From there:
The classroom tool page saves your roster and color theme to your browser automatically as you edit. There's nothing to click.
That covers reopening the same wheel on the same browser next class.
If you want a shareable link so students can spin it themselves from their own device, build the wheel in the full editor on the homepage instead.
Or if you want to embed it in a slide deck, do the same. Sharing isn't available from the classroom tool page itself.
See how to customize and save a wheel of names for the full walkthrough, including what to check if a save doesn't stick.
Remove names after they're picked, if you want everyone to go once. Delete a called-on student's entry after their turn, or drop their weight to 0 in the full editor.
That way the wheel only re-includes them once you reset the list.
This mirrors the "equity sticks" technique researchers describe: pulling a name out of the cup once it's used (Edutopia, 2023), just automated.
Weight for fairness, not just randomness, if you're using the full editor.
Every entry defaults to equal odds, but you can raise the weight on students who haven't been picked recently.
Or lower it for someone just called, if you're running the wheel across multiple sessions and tracking participation.
This control lives in the full editor, not the classroom tool page.
Give thinking time before naming the student, not after.
Wait-time research from Rowe (1986) found that extending think time from one to three seconds meaningfully improved response quality and length (Structural Learning).
So pose the question, count silently to three, then spin.
Use "warm calling" for anxious students. If a student struggles with being put on the spot, tell them in advance which day or topic they'll likely be called on.
Do this rather than relying purely on the random spin.
