The most accurate and comprehensive reason for avoiding overly broad essay questions is:
Broad questions can confuse students and make it difficult to focus their answers.
When questions are too broad, students may struggle to identify the specific aspects of the topic they should address, leading to vague or unfocused responses. This can ultimately hinder their ability to demonstrate their understanding and apply their knowledge effectively. Additionally, broad questions may result in varied interpretations, further complicating the assessment process for both students and instructors. Therefore, crafting more targeted and specific questions encourages clearer, more focused answers that better reflect a student's understanding of the material.
