Hi Rebecca,
I do 8am-6pm with homework assignments. Usually the first hour of the day is dedicated to answering questions, clarifying what was taught the day before and future pacing what will be covered during the day. Lunch is an easy break with light discussion (unsupervised). This timing has been working well in Malaysia. Have a great Prac Training with your students because I know they definitely will ?
Christmas greetings from Malaysia and happy holidays!
Terence
