Now that the spring school session is in full swing, I'm posting a sample animation curricula that I'm implementing for Computers4kids. I hope it's useful for those of you out there putting together some CS project based learning activities! This sample is a multi-session approach good for both classroom size (I'd recommend no more than 20 students working in pairs) and one-to-one over a 27-36 hour period (1 to 3 hrs sessions each):

Session 1 (3 hrs):

Hour 1:Within Alice 2.3, students to select and add a character from each of the Alice folders to get acquainted with their resources. I'd suggest deleting characters as they go along to practice that feature, too, as well, using the edit features before they hit "done" to see how positioning characters works.

Hour 2: Assign a project theme (i.e. "Create a story describing superpowers") that must include at least 1 "he/she builder" character, 1 "power" character, and one external 2D character that they've built outside Alice and imported into their scene.

Hour 3: Students to create a storyboard outlining their Alice script and give a short presentation to the class, including any tips they found helpful to teach others.

Session 2 (3hrs):

Hour 1: Create at least 1 custom animation "method" that supports the story created
Hour 2: Start coding the animation, using your custom "method" and at least 1 "loop" and "if/else" statement
Hour 3: Create 1 custom sound in an external audio application (i.e. Audacity) and import it into your Alice code.

Session 3 (3 hours):

Hour 1: Continue work to finalize your animation coding and testing
Hour 2: Screen capture (i.e. Jing, Screencast-o-Matic) or upload your project (i.e. if using Kodu, to Xbox)
Hour 3: Present to the class and discuss what worked and didn't work during the creative process

Repeat using at least 2 other animation platforms (Scratch, Kodu). At the end of all 9 sessions, students to document on class wiki which platform they preferred and why. Teacher to create a twitter group at session start (i.e. #Animate_this!) to encourage class interaction, questions outside class and beyond the classroom.

I'm looking forward to hearing about your results!
