Is a "no no" at our school. I understand the need for students to all be involved and working together to come up with answers. I understand how teachers can tend to only call on those with their hands raised, which in turn, can be the same students over and over again. I get that other students can slip through the cracks because they never raise their hand or get called on but.... I feel that the no had raising is possibly leading to the issues we are all having which are shouting out answers out of turn. Thoughts? Opinions? How do you teach the WBT rule about hand raising when the students "aren't supposed to raise their hands"?
