Rather than working solely in isolation, learning and working communities collaborate.
Here is a simple technique any teacher, principal, parent, or leader can implement. Have people volunteer to relate something that SOMEONE ELSE has done successfully. Then decide on how often this activity should be conducted, such as weekly or monthly.
A collaborative spirit grows by having others share incidents of someone other than him/herself. Examples of incidents could be helping someone, using a new procedure, or sharing a successful technique.
Rather than the usual approach of the leader or a committee recognizing one person above the others each week, month, or year, sharing activities or incidents empowers the community without the negative "punished by rewards" syndrome created when a deserving person does not receive the award.
