To remain an effective teacher, one must pause often and be the learner. To become the learner you must erase past prejudices, old routines and genuinely become the learner. You have to understand that all students are different. They have different needs, abilities, agendas and, most often overlooked, pride. Like modern computers, some operate at 33mhz while others zip through at 700mhz.
Some students have huge hard drives for brains while others only have minimum capacity.
Some learners have great attention spans, while others are short lived. The common thread, they all want to learn. They all need to learn. It is so natural for all of us trying to provide guidance to the naive inventor to fall into repetitive routines and traits. The teacher who feeds egos instead of minds.
