Here are the ten rules about
testing. If you
have any others
Multiple choice questions are criticized for testing the superficial
recall of knowledge. You can go beyond this by asking learners to
interpret facts, evaluate situations, explain cause and effect, make
inferences, and predict results.
Write test questions in a simple structure that is easy to
understand. And try to be as accurate as possible in your word
choices. Words can have many meanings depending on colloquial
usage and context.
If you’re using a question stem, rather than an entire question,
ensure that most of the words are in the stem. This way, the
answer options can be short, making them less confusing and
more legible.
All of the wrong answer choices should be completely reasonable.
This can be very hard to accomplish, but avoid throwing in those
give-away distractors as it detracts from the test’s validity. If
you’re really stuck, get help from your friendly this word
This can be difficult to achieve, but expert test-takers can use
answer length as a hint to the correct answer. Often the longest
answer is the correct one. When I can’t get all four answers to
the same length, I use two short and two long.
No big news here, right? Don’t use combinations of these words
in the same question: not, no, nor, the -un prefix, etc. For
example, this type of question could confuse test-takers: ‘Which
of the following comments would NOT be unwelcome in a work
situation?’ Flip it around and write it in the positive form: ‘Which
of the following comments are acceptable in a work situation?’
Make sure that most of your correct answers aren’t in the “b” and
“c” positions, which can often happen. Keep correct answers in
random positions and don’t let them fall into a pattern that can be
detected. When your test is written, go through and reorder
where the correct answers are placed, if necessary.
Did you ever have to convince a SME that he or she can’t have
answer choices that go to ‘h’ in one question and ‘c’ in the next?
It’s something of a user interface issue. Making the number of
options consistent from question to question helps learners know
what to expect. Research doesn’t seem to agree on whether 3 or
4 or 5 options is best. Personally, I like to use 4 options. It feels
fair.
As faulty as they are, tests exist to measure knowledge. Never use
questions or answer options that could trick a learner. If a
question or its options can be interpreted in two ways or if the
difference between options is too subtle, then find a way to
rewrite it.
I hate this rule because when you run out of distractors, All of the
Above and None of the Above can come in handy. But they may
not promote good instruction. Here’s why. All of the Above can be
an obvious give-away answer when it’s not used consistently.
Also, the All of the Above option can encourage guessing if the
learner thinks one or two answers are correct. In addition, the
downside to None of the Above is that you can’t tell if the learner
really knew the correct answer.
