We are getting transfers into the CS major. Success Rate Average GTs CS1 ( ) 72.2% Media Computation Spring % Fall % Spring % Quotes from students surveys I think that we're doing things that I could actually use as an architecture majorI like dealing with pictures and sounds. It was interesting/surprising to learn... Adjusting pictures and sounds because it is something that I will be able to use far into the future. It was interesting/surprising to learn... About how Photoshop works because now I understand what it is doing and I can use it better. Quotes from Interviews with Female Students Did we make it: Relevant? I dreaded CS, but ALL of the topics thus far have been applicable to my future career (& personal) plansthere isn't anything I don't like about this class!!! Creative? Social? How did Women Respond to the Course? Did we make it: Relevant? Creative? I just wish I had more time to play around with that and make neat effects. But JES will be on my computer forever, so thats the nice thing about this class is that you could go as deep into the homework as you wanted. So, Id turn it in and then me and my roommate would do more after to see what we could do with it. Social? How did Women Respond to the Course? Did we make it: Relevant? Creative? Social? Actually, I think [collaboration] is one of the best things about this class. My roommate and I abided by all the rules... but we took full advantage of the collaboration. It was more just the ideas bouncing off each other. I dont think this class would have been as much fun if I wasnt able to collaborate. Next steps A second course CS1316 Representing structure and behavior to be offered in Spring 2005 Present a second course that meets national standards, but still in a media context The first course is about surface level features Professional media manipulation also represents structure: Tree of verses/chorus, scene graph If we represent behavior, too, can make stampedes (Lion King) and villagers (Hunchback) by simply filming the simulation. Next steps An alternative path and a minor The two courses (Introduction to Media Computation and Representing Structure and Behavior) will become a pre-req to our traditional computer science courses. Creating an alternative path into CS We are now getting transfers into the CS major We have now created a minor in CS Creating a BS in Computational Media Joint with School of Literature, Communications, and Culture Next steps Moving beyond GT Versions of Media Computation appearing at other institutions Gainesville College (two year school in Northern Georgia) has offered the course three times Georgia Perimeter College, DePauw, Brandeis, U. California Santa Cruz, U. Illinois- Chicago, Florida Atlantic U., and U. Maryland at College Park teaching their own versions using our materials.
