Retired teachers are seldom invited to take a backward look once they depart their schools on the last day of their teaching or leadership careers. Wise Education Departments, schools and universities involved with training the upcoming generation of teachers, do well to invite retirees to share their knowledge with continuing and future educators. To do so, enables valuable inside knowledge based on their experience to be shared. While teaching, for teachers, is always a process of discovery, it ought not be a process of re-discovery. Sharing learning by coaching can help to avoid regurgitation. My suggestion is that retirees be invited to coach, thereby enriching those of us who remain or who will be our next generation of teachers.
