I used Creative Commons because it is a non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share.
My blog license allows others to copy and share the material in any format. Also to adapt, transform and create the material. Unless you follow the license terms you cannot be allowed to revoke these freedoms.
One way to motivate my students to use Creative Commons material and attributed properly will be to protect always our projects and make them unique and personal. Teachers have to make children aware and conscious about this important issue. Teachers must highlight that not all the online resources and materials are free to use, for using some you will have to pay. I think that a good way to do this is creating a debate to talk with them about what they worried about and what they like.
