I have a tight schedule in the Culianry Arts lab course I teach. I make it a point at the beginning of every class to inform the students of the specific time-line expected for the day and call out reminders regularly. It creates a sense of urgency and also creates specific short term, measurable goals.
At close of day, we discuss the successes and challenges, and I remind them there is always time to improve both speed and accuracy... and usually they do, almost without exception.
