Any time you use the work of another, you should give credit to the creator of the original work or idea. Just like we teach our students to cite their sources, we need to give proper attribution to the creator of a work, image, or resource we use. As instructors, modeling good citation and attribution practices is important. With Creative Commons licenses, attribution is actually a requirement of use.
A commonly accepted attribution format in the open community is the TASL acronym. Every attribution should have the following components and answer each question in italics. Where possible, link to the original components and do include any additional information if it feels relevant or useful.
Title (T) - What is the name of the material?
Author (A) - Who owns the material?
Source (S) - Where can I find it?
License (L) - How can I use it?
