Which question type is least effective for generating discussion among students?

The question type that is least effective for generating discussion among students is characterized as a straightforward inquiry that typically elicits a simple affirmative or negative response. Questions framed in this manner limit engagement as they do not invite elaboration, critical thinking, or differing viewpoints.

In contrast, thought-provoking questions encourage deeper analysis and can stimulate diverse opinions, leading to rich discussions. Canvassing questions seek input on attitudes or experiences, promoting conversation by allowing multiple perspectives, while leading questions, despite their potential bias, often push students to consider specific angles or arguments, which can also foster dialogue. Thus, questions requiring nothing more than a "yes" or "no" response do not create the necessary momentum for meaningful discussions in a learning environment.
