"I Feel Like I'm Teaching in a Gladiator Ring": Barriers and Benefits of Live Coding in Classroom Settings

Abstract

Live coding for teaching-synchronously writing software in front of students-can be an effective method for engaging students and instilling practical programming skills. However, not all settings are conducive to live coding and not all instructors are successful in this challenging task. We present results from a study involving university instructors, teaching assistants, and students identifying both barriers and benefits of live coding. Physical infrastructure, a positive classroom community with psychological safety, and opportunities for teacher development are practical considerations for live coding. In order for live coding to be an active learning experience, we recommend that tools support multiple mechanisms for engaging students, directing audience attention, and encouraging student-led live coding.
