Bob shares his transformative experience of adopting live coding as a teaching method, moving away from perfectly edited coding videos and slides to embrace vulnerability and the iterative nature of software development. He highlights that live coding, where mistakes are made and corrected in real-time, provides a realistic view of programming, helping learners relate better by witnessing the actual process of problem-solving and debugging. This method not only demystifies the myth of flawless coding but also fosters a more engaged and interactive learning environment, encouraging better questions and deeper understanding. Additionally, Bob emphasizes that teaching by live coding offers insights into effective development setups and creates a space for sharing knowledge, which is integral to being a great developer. His approach aligns with the JIT (just in time) learning philosophy, which helps learners overcome tutorial purgatory and imposter syndrome by building confidence through practical, challenging yet achievable coding projects.
