Today when I went to speak at the school I ask the teacher, "Does it really help when I talk?"
Her response is that she has learned not to make a lesson plan for the next day except to allow class discussion about my presentation. The students drive the discussion about my talk and all of their personal experiences. They share experiences and they comfort fellow students that are experiencing things in their life and family. She said her classes and discussions after the talks on Tuesday were unbelievable this morning. Students amazed her with their observations, questions and open discussions.
That is satisfying for me to know.
ps., I guess one measure of performance is after I spoke today I had several kids lined up to shake my hand and thank me for talking to them. Even if the message doesn't work it shows there are some polite kids going to that school. lol
