Encourage: 

"Can you tell me more?"

"Could you give me more detail about this problem?" 

Clarify:

"When did this happen?"

"Can you tell me exactly what the student said to you?"

"How did you feel about the principal's comments in front of the class?" 

Restate the facts: 

"So you'd like a larger role in planning small-group activities?"

"I guess you're saying you need more backup in dealing with the problem kids."

Reflect:

"You seem very upset about what happened today."

"You sound angry about playground duty." 

Summarize:

"I'm glad you're willing to offer me more input in what we do in the classroom. It will make me feel more excited and productive. We've agreed to coordinate our planning periods so that we can sit down together and exchange ideas." 

Validate:

"I really appreciate your willingness to help solve this problem."

"I know it took courage for you to bring this up. I'm glad we talked about it."
