Make it easier to share.
You see the badges on Web sites, and they make it easy to decide what you can do with the information. CC-BY is my favorite license. It means you can use the page contents and your “cost” is acknowledging the original author. That’s just common courtesy. This is the way to help teach your students how sharing works. It also encourages them to think of others in everything they do.
The CC-BY license is just one of the licenses that Creative Commons has developed. Choose the one which suits your needs.
I encourage you to choose to use the Creative Commons licenses and teach your students about them, but here’s your chance to donate some money, too.
For the record, I donated today.
