V. Designing Effective Constructed Response Items
A. Clear and Concise Wording
Clear and concise wording in constructed response items is important to reduce confusion and ensure that students understand what is being asked of them. Precision in wording is crucial to avoid ambiguity, and appropriate context is necessary for advanced learners, especially in fields like medicine, to effectively apply their knowledge. Balancing simplicity and complexity in question framing is essential in challenging students without confusing them.
BASIC Information
Clear and concise wording in constructed response items means framing questions in a straightforward manner, using simple language, and avoiding unnecessary jargon. The aim is to reduce confusion and ensure that students understand precisely what's being asked of them.
For PA students, medical terminology and complex clinical scenarios are part of the curriculum. However, when assessing their knowledge, it's crucial to ensure that the question's wording isn't the barrier to understanding. Instead, their medical knowledge should be the primary focus.
INTERMEDIATE Information
While it's essential to keep questions simple, they also need to be precise. A lack of precision can inadvertently introduce ambiguity.
Active Voice: Use active rather than passive voice for clarity. For example, "What does the drug do?" instead of "What is done by the drug?"
Specificity: Instead of asking broadly about a topic, narrow it down. For instance, instead of "Discuss diabetes," ask "Describe the pathophysiology of Type 2 diabetes."
Avoid Double-Barreled Questions: These are questions that touch on two topics but only allow for one answer. For example, "How do you diagnose and treat hypertension?" Ideally, these should be split into two separate queries.
In a clinical assessment about cardiovascular diseases, instead of asking: "Talk about heart conditions in elderly patients," a more clear and concise question would be: "Describe the common risk factors and presentation of congestive heart failure in elderly patients."
ADVANCED Information
For advanced learners, especially in fields like medicine, clear and concise wording often requires appropriate context. The context sets the stage for the question, ensuring that the student understands the scenario and can apply their knowledge effectively.
"Balancing Simplicity and Complexity:
While the essence of the question should be simple, the medical field often demands complexity. It's about framing complex scenarios in an understandable manner. This balance ensures that the question challenges the student's knowledge without confusing them with its wording."
Use Relevant Clinical Scenarios: Ground questions in real-world medical situations. This gives context and makes the question relatable.
Limit Unnecessary Information: While details are essential, avoid overloading the question with irrelevant information. It can distract from the main point.
Review and Revise: Once a question is drafted, it's beneficial to have peers review it. They can provide feedback on clarity and potential ambiguities.
Consider a clinical case assessment. Instead of presenting: "A patient comes in with fatigue, blue-tinged skin, and shortness of breath. What could be happening, and what are your next steps?"
A more concise, clear, yet contextually rich question would be: "A 50-year-old male smoker with a history of hypertension presents with fatigue, cyanosis, and dyspnea. Based on these symptoms, provide a differential diagnosis and outline the key diagnostic tests you would order."
