Professor David J. Malan, a prominent computer science educator at Harvard University, offers an innovative learning experience in his CS50 course by integrating GitHub and custom tools for hands-on assignments. With a large class size and diverse student backgrounds, Malan emphasizes practical applications across various fields to provide a solid foundation in computer science. To facilitate Git learning, he developed "submit50," a tool that simplifies Git commands and allows students to gradually understand GitHub’s intricacies. The course includes engaging projects like "C$50 Finance," where students create stock trading simulations, and culminates in the CS50 Fair, a celebratory event showcasing student work. Malan also extends learning beyond the classroom with "CS50 Live," a platform connecting course content to current tech news. This approach not only prepares students for further endeavors but also instills a sense of accomplishment and pride in their work.
