The Raspberry Pi Foundation was founded to promote the study of computer science in schools. The foundation has developed the Raspberry Pi, a small, low cost computer that serves as a good platform for engaging in hands on learning. It is an effective way to dive into computing and programming in languages such as Python, as it can do everything a typical desktop computer can do - data processing, playing games, or even browsing the Internet. Their website has a large collection of resources for learning more about this system, as well as some ideas on how to start out working with it.
