A big issue is time constraints. As an Adjunct, I spend a great deal of time responding to discussion posts, and answering emails. On top of that grading needs to get done. I already work more hours than is contracted for. I do it because I care, but I another, full-time job, where I get health insurance and try to earn a living. My time is just limited.

I have found Multiple choice and T/F questions to be most useful. I have a better understanding of how to make sure the questions are fair, and help achieve the ability better assessment of the student's knowledge and understanding.

I often ask "any questions" but usually at a breaking point between topics before moving on. I will however, ask some questions I have heard in past classes, through email and after class, so I can engage students in a discussion to test for knowlecge without asking  direct question.

I am currently working in a hybrid system, with class time and online activities and discussions which I monitor. I would think a flipped would work best when the out of class portion is more of a review or background information to the activity in class. It can also be a prompt with a question that might pique someone's interest in fining out more in class.

I learned that I should continue, or maybe even strengthen my Follow-up questions at the end of class to reinforce the topics covered and place stronger emphasis on the main points of the unit connecting them to the relevance of the lesson.
