A short statement increases the likelihood that the question will be understood. Test the clarity of the question by trying to answer it without the help of the possible answers. Use positive form as much as possible and, if negatives must be used, emphasize them by using bold or capitalization in the stem. Write all possible answers grammatically consistent with the stem of the problem. Make sure that the correct answer is clearly the best choice to the informed user and choose alternatives that are conceivable enough to lead to serious thinking.
Wrong answers given by students on previous tests are a very good source of alternatives answers.
Vary the position of the correct answers. Create your own set of rules if it improves the strength of the question. All rights reserved.
