I've just started reading a very interesting book, You Can't Say You Can't Play written by a kindergarten teacher, Vivian Gussin Paley. The book was assigned to me to read for a class I'm taking this summer, Social and Emotional Competence in the Preschool Classroom.
The book is focused around a kindergarten classroom that has a very common problem in classrooms all over the world, students excluding other students from joining in their play. When the problem in this teachers class escalates to the point that there are children in tears daily, Mrs. Paley implements a new classroom rule, you cannot say the words, "You can't play" in her classroom.
The book follows the aftermath of implementing such a rule, the thoughts of the teacher throughout the remainder of the school year, and the outcomes she experienced in her classroom. I won't spoil it for anyone interested in reading it, but it was a great read!!
