It is a common misconception that true/false questions are the easiest to construct. It is also a misconception that they are the least effective. True/false questions can be tricky to write well. The items can easily be ambiguous, too wordy or so simple that the question does little good. But well written true/false questions can be challenging to take, and effective in measuring the learner's level of understanding.
Guidelines for Writing Effective True/False Questions
Keep wording clear and unambiguous.
•Make each item test the truth or falsity of only one statement or piece of information.
•Avoid specific determiners such as "always", "never" or "sometimes".
oMost questions that include words like "always" or "never" will be false, since there are usually exceptions to every rule. On the other hand, questions that include words like "usually" or "sometimes" will be true, since these items will be the exceptions.
•Make the question a positive statement whenever possible.
•Make sure no item is so simple or obvious that it can be answered on the basis of common sense alone.
•Keep the questions short and to the point.
