This is just a mere summary of the general and most common ideas related to Projec Based Learning, drawn from experts and many authors, that anyone could find easily on the Internet and other sources, but in this publication, I have tried to write them down in a practical and easy to follow way, even for those who never have listened about it before. If I were asked for the reasons to compile these ideas, I would say that I needed them to learn how to start working with projects, in a practical and useful way, in my English as a Foreign Language classes, in a primary school in Sagunto, which is the beautiful village near Valencia in Spain where I am currently developing my teaching career.
