The catch with true/false questions: a coin flip scores 50%

Every true/false item can be guessed right half the time. On a five-question warm-up, a student who doesn't read a single statement still has a real chance of "passing". Try it:

What are the odds a pure guesser passes?

0 correct5 correct

A student who guesses every answer expects 2.5 right (50%) and has a 50.0% chance of reaching 3/5.

That’s high. Add questions, add options, or raise the pass mark so the score reflects knowledge rather than luck.

This doesn't make true/false questions bad; it means you need more of them, or you should mix them with other types. Twenty true/false items take about as long to answer as eight multiple-choice ones and cover more ground.

Writing true/false statements that work

  • One idea per statement. If half the sentence is true and half is false, students who know the content get it wrong.
  • Avoid giveaway words. "Always", "never" and "all" usually signal false; "usually" and "sometimes" signal true. Test-wise students know this.
  • Balance the key. Aim for roughly half true and half false, not in a pattern.
  • Target misconceptions. "Heavier objects fall faster than lighter ones (ignoring air resistance)" tells you much more than a statement copied from the textbook.
  • Add an explanation. Use the explanation box so students see why a statement is false once they submit.

Sample true or false questions

A few you can paste straight into the bulk box:

TF | Sound travels faster in water than in air. | true
TF | The Great Wall of China is easily visible from the Moon with the naked eye. | false
TF | A tomato is botanically a fruit. | true
TF | Bats are blind. | false
TF | Lightning can strike the same place twice. | true

Questions teachers ask

How many true/false questions should a quiz have?
Enough that guessing can't carry a student. With 20 items and a 70% pass mark, a pure guesser passes about 6% of the time; with 5 items it's about 19%. The calculator above shows the exact odds for any length.
Can I mix true/false with other question types?
Yes. Add multiple-choice, short-answer or number questions to the same quiz with the buttons under the question list.
Should I penalise wrong answers to discourage guessing?
Negative marking is used on some standardised tests, but in the classroom it mostly punishes cautious students. Adding more items is a fairer way to reduce the effect of luck.
