You don't need to be an expert Moodle teacher or course creator to use the solutions in this book. However, this book assumes that you can use Moodle's basic features. You can learn Moodle before reading this book or learn it as you practice implementing these solutions.
For example, one of the learning solutions in this book is "Group Project". This solution uses Moodle's standard wiki module. To implement the solution, you should know how to create a wiki in Moodle. You could learn how to create a wiki from another book on basic Moodle usage, from the online help, or from the moodle.org forums. However, this book will not give step-by-step directions for creating the wiki. It will give directions for adapting the wiki for Group Project.
If you're new to Moodle, consider practicing on the Moodle demonstration site at http://demo.moodle.org/.
