Secondary schools are teeming with teens whose attitudes and actions can sometimes be unpredictable, uncalled-for and unproductive.  Familiar problems like bullying, cheating, teasing, whining, sleeping in class, fighting, showing up late and failing to do assignments, frequently disrupt classroom instruction, jeopardise student success and undermine school cohesion. But it doesn't have to be that way. In SAFE & HEALTHY SECONDARY SCHOOLS, teachers, administrators and support staff learn how they can build a collaborative and cooperative learning environment where secondary school students receive the positive behavioural support they need to succeed. Included are strategies on how to provide adequate supervision, forge relationships with alienated and disconnected students (and their families) and empower students to deal with anger and frustration rationally rather than recklessly. Insights into how the teenage brain influences behaviour, for better or worse, are, also, provided. True-to-life stories explain how teachers, administrators and support staff can create collaborative and cooperative learning communities.
