MATCHING
• Pro’s
• Can assess a lot of info in a confined space
• Fairly low probability of guessing
Evaluation
• Assess recognition not recall
• Best Use:
• Knowledge recall
• Add additional “distractor” items
to increase rigor

MULTIPLE CHOICE
• Pro’s
• Very versatile
• Easy to score

• More challenging to write
• Assess recognition over recall
• Best Use:
• Factual, conceptual, or
procedural information

SHORT-ANSWER
• Pro’s
• Assess unassisted recall
• Relatively easy to write
Evaluation
• Only useful if you can give a
short answer.
• Must be worded carefully to
avoid scoring problems
• Best Use:
• Assessing information that you
expect to be memorized

SUMMARY
• Each question type has pro’s and con’s
• Question type should be guided by the
learning objective to be assessed.
• Limited options for assessing higher
taxonomy
CONSTRUCTING OPENENDED QUESTIONS
WELL-DEVELOPED ESSAY QUESTIONS
• Mirror well-defined learning objectives
• Assess most appropriate content types
• Require content recall, evaluation, and
reasoning
• Are clearly written
• Provide boundaries
• Have well-defined grading criteria
http://testing.byu.edu/info/handbooks/WritingEffectiveEssayQuestions.pdf
APPROPRIATE CONTENT
• Content that justifies high-level mastery
• Construction, higher-order taxonomy
• Analysis (analyze, compare, contrast, interpret)
• Evaluation (evaluate, explain, justify)
• Synthesis (develop, construct, modify)
• Complex, multi-step thought processes
• Simulation of real-world processes
• “given a patient-case scenario”
If content / processes can be assessed by methods other
than essay questions, they probably should.
KEY ELEMENTS
• An ideal essay question requires students to:
• Recall facts
• Make an evaluative judgment or develop a novel
solution
• Explain reasoning behind response
• The question should include:
• Task
• Problem situation
WRITING FOR CLARITY
• Ensure your question requires higher-order
thinking
• Make sure the task is defined and focused
• Make sure the problem situation includes
adequate detail
SETTING BOUNDARIES
• Increasing structure prevents
• grading problems
• bluffing
• Avoid indeterminate questions
• Students can redefine and answer with info the
know well
• Give time / space limits
• Establish rules for answers
ESTABLISHING GRADING CRITERIA
• Must have specific criteria for grading
identified a priori
• Create a model answer
• Assign point values
• Peer review
• Identify essentials in response
• Determine whether partial credit is
allowable and how will be awarded.
• Grade blinded
DIFFERENT GRADING APPROACHES
• Comprehension / Understanding
• Screen responses for key elements
• Assign points for each element present
• Scores for presence of content only (potential bluffing)
• Reasoning / Complex Processes
• Must assess complete response (time consuming)
• Consider a rubric approach to limit subjectivity
• Problem – Solution
• Encourage requiring students to show work
• Can grade multiple steps in process
GRADING TIPS
• Grading scheme should be easily
interpreted by other graders
• Self-explanatory
• Point values that can easily be tallied
• When multiple graders, encourage frequent
communication and comparison of results
• Before grading, screen a sample of
responses for consistency
OTHER ISSUES
• Exam length
• Addressing unidentified “correct” answers
• Partial credit or all-or-none
• Practice examples
• Multiple examples
• Should not be the same questions as on exam
