This book provides strategies teachers and principals can use to improve the culture of their classroom or school. Strategies are based on discoveries in Neuroscience about how the chemistry of our brain is linked to our relationships. The science highlights the importance of trust in school culture. Our desire and ability to trust each other has been hard-wired into our DNA by evolution. Our ability to work together and teach each other has played a pivotal role in the survival of our species. Building trust can be learned and improved with practice. It also brings brain research out of the lab and into schools. Readers will learn how to apply these strategies from principals and teachers using them. Readers will learn why culture is too important to be left to chance, and how a positive school culture can be built. Readers will learn how to use these strategies to "bathe brains" in the neurochemicals needed to improve the culture of any school.
