Helping shape a positive, social environment for students?

I don’t think this could be controversial per say, but I figured I would get more input and responses here.

A mom from my daughters school shared this article on Facebook.

I wish the article specified on what she does after choosing what children need the added help. Does she do this in a way that the child doesn’t feel singled out?

Do you think this would be a great plan for teachers to implement in their classrooms to help kids gain the positive socializing experience they need?
