GitHub Classroom, launched in 2015, has become a valuable tool for educators like Geoff Schmit, who integrates it into his AP Computer Science curriculum at Naperville North High School. Geoff emphasizes the importance of teaching students real-world engineering skills, such as source control and unit testing, using pre-filled repositories to streamline their learning process. By simplifying the assignment management process through GitHub Classroom, students can focus on coding without the technical hurdles of setting up environments. Geoff's approach, inspired by educational theorist Dr. Mitchell Resnick, involves creating assignments with "low floors, wide walls" to encourage creativity and engagement beyond the minimum requirements. This method has fostered a classroom environment where students feel free to take risks and collaborate, as their work is largely practice-focused and not heavily graded, which enhances their learning experience and willingness to explore new concepts.
