True or False Questions: When They Work, When They Fail, and 40 Ready-to-Use Examples

TL;DR. True/false is the fastest question format there is — to write, to answer, and to grade — and it earns a place in warm-ups, quick recall checks, and misconception hunting. Its weaknesses are just as real: a coin flip scores 50%, and surface readers can do well without understanding anything. The fixes are well established (make students correct the false statements, pair with short-answer follow-ups, use it formatively rather than for grades), and this post covers them, followed by a bank of 40 ready-to-use true/false questions across science, history, geography, English, and general knowledge — every answer checked by hand.

Part 1: Making true/false actually work

Where the format shines

Where it fails — and the standard fixes

The 50% guess rate. A student who knows nothing scores around half by guessing. That makes raw true/false scores nearly useless for grading in small doses. Fixes: use the format formatively rather than summatively, use more items (guessing luck evens out across 20 questions far more than across 5), or use the correction technique below, which removes guessing value entirely.

It rewards surface reading. Students learn to scan for absolute words — "always," "never," "all" — and mark those false without engaging with the content. (They're right often enough that this is a rational strategy.) Fix: write false statements that are wrong on substance, not on an absolute qualifier, and include some true statements that do contain strong words.

The best fix: make them correct the false ones. Require students to rewrite every "false" statement so it becomes true. "The Declaration of Independence was signed in 1876 — false, it was 1776." This single change converts a coin-flip format into genuine recall: you can't correct a statement you don't understand, and guessing "false" without a correction earns nothing. It also pairs naturally with a short-answer follow-up — in SimpleQuizMaker you can mix formats in one quiz, since true/false, multiple choice, short answer, and fill-in-the-blank are the four built-in question types, and the generator will write true/false items directly from your own pasted notes or documents. For a fuller comparison of when each format fits, see quiz question types explained.

One writing rule above all: no debatable statements. Every item below is unambiguously true or unambiguously false. If a statement needs a "well, technically…" — it doesn't belong in a true/false quiz. That judgment call is the main thing to check when reviewing AI-generated or borrowed questions.

A quick note on grading and follow-up

Because true/false grades itself so quickly, it's tempting to stop at the score. Don't — the real payoff is in the wrong answers. When a third of the class marks a false statement true, you've located a shared misconception worth five minutes of reteaching, which is more actionable than most test data gets. A simple routine: run the round, sort items by miss rate, and open the next lesson by putting the two most-missed statements back on the board for the class to argue about. Students defend their answer, then correct the statement together. The format's biggest weakness — that it invites quick, shallow answers — becomes the setup for the most engaged discussion of the week.

Using this bank

Pull a subject section as a two-minute warm-up, mix items across subjects for a general-knowledge round, or use the false statements as correction exercises. If you want a bank tailored to your own unit rather than these general topics, paste your lesson notes into the quiz builder and generate true/false items grounded in exactly what you taught — then review each one against the no-debatable-statements rule above before sharing.
