1) Make it meaningful and present a clear task.
The stem in multiple-choice questions (MCQs) is the question or statement that students must respond to by choosing the best answer from the options provided. It should be clear, concise, and to the point. When crafting meaningful stems, it is important to use focused wording, frame the question positively, and ensure the stem is a meaningful question on its own. Additionally, advanced techniques in designing stems involve engaging the student's higher cognitive skills to test understanding rather than mere recall.
BASIC Information
In multiple-choice questions (MCQs), the stem is the question part or the statement to which the student must respond by choosing the best answer from the options provided. An effective stem should be clear, concise, and straight to the point.
For a fair assessment, it's vital that students understand exactly what's being asked. If the stem is confusing or ambiguous, students might pick the wrong answer even if they have the right knowledge.
INTERMEDIATE Information
Focused Wording: Avoid excessive verbiage. Directly state the problem in the stem without unnecessary context.
Positivity: Frame the question positively unless there's a specific reason to use negatives. If negatives (e.g., "NOT," "EXCEPT") are used, emphasize them with capital letters.
Completeness: The stem should be a meaningful question by itself and shouldn't rely too much on the answer choices to make sense.
Avoid "All of the above": This can confuse students if they believe more than one option is correct.
Test the Stem: Before finalizing, ensure the stem makes sense by reading it out loud or having a colleague review it.
A confusing stem might be: "When considering respiratory issues, which organ...?"
A clearer version could be: "Which organ is primarily responsible for the exchange of oxygen and carbon dioxide in the human body?"
ADVANCED Information
An ideal MCQ stem not only asks a clear question but also engages the student’s higher cognitive skills, ensuring the question tests understanding, not mere recall.
Scenario-Based Stems: Incorporate real-life clinical scenarios to make questions more applicable and to test practical understanding.
Integration of Concepts: Craft stems that make students integrate knowledge from various areas, ensuring they're not just relying on rote memorization.
Iterative Refinement: Create multiple versions of the stem, refining and honing the clarity and focus with each iteration.
Feedback Loops: After an exam, gather feedback from students on particularly challenging or confusing stems and make necessary adjustments.
Align with Learning Objectives: Ensure that the stem directly relates to the specific learning objectives you aim to assess.
Scenario: "A 65-year-old male patient presents with shortness of breath, fatigue, and swollen ankles. His ECG shows abnormalities."
Rather than a simple recall question like, "What does an ECG measure?", an advanced stem could be: "Given the patient's symptoms and ECG findings, which of the following conditions is he most likely suffering from?"
This stem not only asks students to recognize the condition but also to integrate symptoms with diagnostic findings, leading to a more comprehensive assessment of their understanding.
