Claire Duffy 
Australian Schoolkids‘ Guide to Debating and Public Speaking [PDF ebook] 

This book covers everything kids, parents and teachers need to know about debating and public speaking. Claire Duffy not only demystifies the process but makes it fun by drawing on her many years of experience working directly with students. Learn all about the best way to prepare, the persuasive power of reason, the art of argument and rebuttal and, when it comes to that, how to lose graciously. Including practical tips from the pros and helpful step-by-step examples, this is the essential handbook for making every spoken word count.
