CoCo stands for Compose and Code and it is a digital learning platform that embeds self-regulated learning strategies and Universal Design for Learning supports (including a graphic organizer, audio comments, video models, and text-to-speech) to help scaffold computational thinking and guide students to design and code creative software. CoCo was developed to broaden the participation of underrepresented student groups as a result of our findings from our previously-funded NSF project (Award # 1837380). These findings indicated that although students with high-incidence disabilities were able to participate in computer science instruction, many had trouble navigating coding activities, understanding sequential steps, and creating a plan for their work. CoCo is a tool that can be used as part of computer science instruction to help students engage in computational thinking and plan and code creative products.
