Background and Context: Encouraging undergraduate programming students to think more about their software development processes is challenging. Most programming courses focus on coding skill development and mastering programming language features; subsequently software development processes (e.g. planning, code commenting, and error debugging) are undervalued. Moreover, many of these processes involve tacit thinking that is often seemingly invisible, meaning it can be difficult for teachers to identify and address shortcomings in student processes. Objective: In this paper, we employ a novel approach called Interpersonal Process Recall (IPR) to encourage students to think more about their software development processes. Method: We conducted IPR sessions with five undergraduate programming students--we screen captured them working on programming assignments, and then used the screen captures to stimulate reflection. IPR is hallmarked by several key features, namely its developmental (rather than evaluative) focus, and the use of a facilitator to guide reflection in a structured way. Findings: We found IPR was useful for both the teaching staff and the students, revealing incongruence between the value students placed on certain development processes and what they actually do in practice. Implications: IPR is a novel approach for shining a light on student software development processes. We hope this paper encourages other practitioners to consider adding IPR to their toolbox of approaches for encouraging students to reflect on their software development processes.
