Kent, I do not believe that there are any guidelines regarding this type of questioning. However, I have found that it is best to allow the student to create the parameters. Instructors can provide a "general" selection of questions, which enable the student to decide how much information to devulge. For example, a good icebreaker question would be: Please provide the class or a partner in class with a summary of your experience with the (class) subject. With this the student can be brief or more expansive, depending on what they would like to share with others. Tremayne Simpson
