 Debugging also functions as a reinforcement method we can use once students have an ok mental model of code execution, a necessary pre-requisite for this activity, which can be further developed through debugging ({% cite Ramalingam_2004 %}) alongside their self-efficacy ({% cite Michaeli_2019 %}). Debugging activities can take many forms but most commonly the task is to correct incorrect code, an activity that works best if they are primed with a number of methods of debugging ({% cite Murphy_2008 %}) such as the "Wolf Fence" ({% cite Gauss_1982 %}), commenting out code, or breakpoints.
