Class Activities: Mastering Multiple-Choice Questions by Li Chen https://padlet.com/chenl31/sflvu6k3rigfdv5q Guidelines for Writing Multiple Choice Questions: Stem (Question or problem): • Use clear and concise language that avoids unnecessary complexity or ambiguity. • Employ positive phrasing in the stem. • Avoid using absolute terms like "never," "always," or "only." o If they are necessary, emphasize them by bolding or capitalizing. • Use negative phrasing only when essential for learning outcomes and make sure negative terms are highlighted to stand out to the test-taker. • Exclude irrelevant material from the stem. • Formulate the stem as a direct question or an incomplete sentence. • Review tip: Have someone else read and take the test to check for clarity and effectiveness. Alternatives (correct answer and distractors) should: • Be plausible, clear, and concise. • Should be mutually exclusive to prevent confusion. o Avoid "trick" items or alternatives with overlapping content. • Ensure the content of the alternatives is homogeneous. • Alternatives must be free from any clues that could reveal the correct answer. • Maintain grammatical consistency with the stem. • Alternatives should be parallel in form and similar in length. en-us 2024-03-13 13:46:29 UTC 2024-03-18 15:40:12 UTC hello@padlet.com 1. Rewrite this multiple-choice stem. Remember, an effective stem should be meaningful by itself and pose the problem or question. chenl31 https://padlet.com/chenl31/sflvu6k3rigfdv5q/wish/2917339436
