Hi Tina,
You can develop your questioning skills by looking at a topic or subject from several different ways and then write down some questions of discovery. I have found that by using case studies I can bring out more questions of depth and challenge for my students. After doing several case studies you will start to see what questions are the most effective to use. I write these questions down so I can use them the next time I teach the course. Also, the Socratic method works well in group settings. By presenting 3-4 students a common question they can mull it over, discuss it and then come to solutions to be shared with the entire class.
Another lead in to questioning is to pull up some life experience you know about a student and incorporate it into a question. "Jane, I know that you have had extensive experience working as an EMT and have faced many different situations all based upon trauma, based upon these experiences how did you respond to (then ask your question)".
