SiLAS. Funded by the National Science Foundation, SiLAS is a first of its kind browser-based software that allows students to act out social scenes using video game controllers and microphones to control their own 3D avatars.  Students work in groups or with their teachers. SiLAS records the interaction in real-time, then produces a studio-quality animation that teachers and students can watch and share, critique, and assess. Student-performance data can be tracked by teachers, with charts that show improvement over time. Animations are saved in guardian accounts allowing for year-to-year carryover.
