One of the things that can really get in the way of good inquiry is behavior issues. We all struggle with how to guide children to be able to learn when their behavior is less than ideal. Young children need so much guidance and we need lots of strategies so that we do not resort to yelling, threatening, and other negative measures that do not support the student and in the end just don't work!
