Amjad, In the ultrasound classroom scenario described, providing hands-on practice with a skillful set of questions to be answered before each session will be very helpful with a high number of repetitions. Sometimes creating a specific critical thinking path and requiring the student to answer the questions that follow that thought path can help them understand the value of the critical thinking process as part of the procedure. Even in higher-level thinking scenarios, repetition can be very useful when procedures and diagnoses follow a consistent, logical process. Dr. S. David Vaillancourt
