Questions have long been used as a teaching tool by teachers and preceptors to assess students' knowledge, promote comprehension, and stimulate critical thinking. Well-crafted questions lead to new insights, generate discussion, and promote the comprehensive exploration of subject matter. Poorly constructed questions can stifle learning by creating confusion, intimidating students, and limiting creative thinking. Teachers most often ask lower-order, convergent questions that rely on students' factual recall of prior knowledge rather than asking higher-order, divergent questions that promote deep thinking, requiring students to analyze and evaluate concepts. This review summarizes the taxonomy of questions, provides strategies for formulating effective questions, and explores practical considerations to enhance student engagement and promote critical thinking. These concepts can be applied in the classroom and in experiential learning environments.Keywords: questioning, critical thinking, pedagogy, effective teaching, teaching tool
INTRODUCTIONUsing questions to teach is an age-old practice and has been a cornerstone of education for centuries. 1,2 Questions are often used to stimulate the recall of prior knowledge, promote comprehension, and build critical-thinking skills. Teachers ask questions to help students uncover what has been learned, to comprehensively explore the subject matter, and to generate discussion and peerto-peer interaction. Student-initiated questions increase higher-order learning by requiring them to analyze information, connect seemingly disparate concepts, and articulate their thoughts. 3 Indeed, questions are ubiquitous, but are the right kinds of questions -ones that promote learning, not recall -asked at the appropriate time? 4 Poor questions can stifle learning by creating confusion, intimidating students, and limiting creative thinking. 5 Effective questions asked in a psychologically safe learning environment support student learning by probing for understanding, encouraging creativity, stimulating critical thinking, and enhancing confidence. 6 The art of asking the right questions at the appropriate time is not innate. 7 Bloom's taxonomy of learning categorizes cognitive levels into several domains. 8 Questions that elicit responses in the knowledge, comprehension, and application domains are frequently considered lower-order questions, while questions in the analysis, synthesis, and evaluation domains are considered higherorder questions. 9 Higher-order questions elicit deeper and critical thinking; therefore, teachers are encouraged to ask questions in these domains (Table 1). 2,[10][11][12] This does not mean that lower-order questions should not be asked. It is appropriate to ask questions to address all cognitive domains as long as the desired learning outcome is kept in mind and a good mix of questions is used during each teaching session. 2 Given that the learning objectives in most courses in graduate and professional degree programs are often intended to stimulate high ord...
