The Creative Commons logo can be found on many different websites, although I previously did not know what it meant. Here, I am using the Creative Commons logo under the guideline that it links back to the Creative Commons website.
I think Creative Commons can have a great impact on student learning. First, students using Creative Commons materials may pause and think about the source of their material, the collaborative nature of the Internet, and copyright law in general. When students create projects using Creative Commons materials, they may become more excited and vested in their work, knowing that they are contributing their own ideas to the creativity of people around the world.
I currently use images from Google Image search and video clips from YouTube in my teaching, but after learning about Creative Commons I will be sure to find sources that have Creative Commons licenses. If they don't, I may begin to spend more time seeking permissions from the owners of these materials.
On the other side of the coin, I myself like to share my own work or my student's work on my classroom blog and other public arenas. As a General Music teacher, I like the idea of sharing recordings of my students' in-class performances for others to hear. Of course, I make sure that the songs we use for these recordings are from the public domain or are original compositions, either by myself or my students. I like the idea of adding a (free) Creative Commons license to these recordings and other original materials so that others can take our ideas and expand on them. However, a potential negative of opening up these materials for others' use is if someone were to take our work and put a negative or inappropriate spin on it. My priority would be protecting my students and the integrity of their work.
Many sites now make it easy to access materials with Creative Commons licenses. For example, an entire section of Flickr is devoted to searching for photos with Creative Commons licenses. Using this section of the site, I was quickly able to find interesting and thought-provoking pictures of various musical instruments like the one seen below. The Creative Commons section of Flickr would be a great place to introduce the concept of Creative Commons to my students, particularly if I were to embed that learning activity into a larger project such as student-created presentations on the different instrument families.
David Jakes has a lot of other great ideas on how to incorporate Flickr into the classroom.
