A true-false question is a statement that is either correct or incorrect.
Characteristics of True-False Questions

- Can be factual or can be a thought question that requires reasoning
- Can be used in most disciplines
- Used to quickly poll a class as an introduction to a discussion or determine knowledge of topic
Advantages of True-False Questions

- Easy to write.
- Easy to score.
- Scoring is objective.
- More information is sampled from a great deal of content.
- Effective when assessing misconceptions, cause-effect relations.
Disadvantages of True-False Questions
- Measures only low level of learning - remembering and understanding.
- Need a larger number of items to distinguish stronger and weaker knowledge levels.
- Students have a 50 percent chance of being correct, just by chance.

Constructing True-False Questions
- Make questions require application of knowledge as much as possible.
- Always make certain the statement is unequivocally true or false.
- When using opinion statements, cite the source that will make the complete statement true or false.
- Develop approximately the same number of true and false statements.
- Do not consistently make true statements longer than false statements, or vice versa.
- Avoid negative and complicated statements.
- Words such as "all," "only," "never," and "always" give hints about the answer and are usually false. Use them only when the question is to measure understanding.
- Words such as "generally" and "usually" tend to be true, so avoid their use.
- Do not randomize the response order in true/false questions.
