Learning about Learning Objectives

For years I've thought that there must be better ways to introduce objectives.  I'd never been that innovative with them.  A couple of weeks ago, I happened across a fantastic slideshare and have used several over the past few weeks.  I've told the children that I'm trying lots of different ways and that I want to know what they think.  They love the rebus idea, and really liked seeing Einstein tell them about their planned learning; however, they are not fond of deciphering pictures or of the 'order the learning' idea.  Today, however, I trialled the "arrow" with grade breakdowns - the feedback from the children was phenomenal.  My Year 11 'afternoon' group told me how they felt they had been able to track their progress and to see what they could do and where to go - they set their own 'personal objective' at the start of the lesson and built up to it slowly by the end.  I can't believe what a difference simply by introducing objectives in a different manner.
