I remember when I first figured out the "power of the pair". I had walked onto our school library and the noise was way above what I would expect.
The Power Of The Pair
It’s not a ‘sit and be still’ classroom -and that means students are no longer viewed as a single learning ‘receptacle’. Be it concepts in the science lab, or reasoning for a development in world affairs their partner is always the first sounding board for that. They have a present and willing person to speak and listen to. We often switch partners, or move to larger groups, during activities but for the start/end of class students know who and where their ‘home partner’ is.
