I came across this post from the Derek Bok Center for Teaching and Learning at Harvard University detailing the different categories of questions:
Some Different Types of Questioning
Facilitating student discussions can be one of the most difficult aspects of teaching. Listed below are some different types of questioning one might use to encourage student participation in class.
Open Ended Questions
What’s Going On? What do you make of this situation? Casting question nets out to see what comes in. Listening for entry and emphasis points.
Asking for Information
Where? When? Who? What? Facts and opinions.
How do you interpret and explain “A” and “B’s” impact on the situation?How do you weave these points into some kind of understanding of what else is going on, possibly behind the scenes?
Why do you say that? How would you explain� Where is the evidence for what you say? How can you say a thing like that? Is that all? That’s just the opposite of what Student X said. Can you persuade him/her?
Exploring the issues. What else? Can you take us farther down that path or find new tributaries? Keep going? Therefore?
How would you relate your points to those mentioned by Student A or to something else you said?
How would you understand X in light of Y?
Which issues do you consider most important? Where do you start? How would you rank these?Action Questions
What would you do in Person X’s shoes? How?
What do you think would happen if we followed Student Z’s action plan? Give us a forecast of your expectations. How will he/she react to your thinking?
Generalizing and Summarizing Questions
What inferences can we make from this discussion and case? What generalizations would you make? How would you summarize the three most critical issues that we have discussed? Can you summarize the high points of the discussion thus far?
What I find interesting is that, while intended to be questions asked of students in a classroom, these exact same questions are the sort of things that ought to be asked in the workplace when attempting to promote continuous improvement. This list of questions serves as a useful study guide for anyone looking to conduct a root cause analysis or initiate a process change.
