You can utilize it by making the questions from different sides. you have to set the questions according to the need which make the students to think. Not even the questions but also the timing that when to ask the questions some time at the start and some at the middle and at the end. Asking questions also have different research you can also take help from that research
In the Problem-Based Learning model I developed, I have a number of educational tools embedded in the case template to drive cognitive thinking and deep learning. These include identification of problems, generating hypotheses for each problem, developing an enquiry plan, interpreting findings collected, weighing evidence for and against each hypothesis, handling uncertainty, making decisions based on available evidence, etc.
I recommend for you reading my book
