It's important to ask if some educators still rely on rigid routines in their classes. Do they recycle in-class worksheets, matching columns, PE drills, current event reports, and other time-honored but questionably relevant practices? Do some teachers create their own jargon and customs? Do they demand that students conform to their own rules and peccadilloes, and is this a good thing? Structure, or failure to update to meet current learner needs, can be both a student's best friend and worst enemy.
