STUDENT'S     PROGRESS

All students learn new skills at different speeds.  Some, no matter what method you use pick up a new skill instantly.  Others will get it after one or two more lessons.  Others might need a different skill approach and/or a lot of repetition.  Too many times Teachers move all of their students onto a new skill BEFORE every student has mastered the previous skill.  For those students who haven't mastered the skill it is UNFAIR for them to have this happen.  The Teacher needs to take the time to remediate the skill completely before teaching them a new skill.  It is setting them up for failure when the skills previously taught aren't mastered fully.
