Abstract
Despite the growing number of sketch recognition sys-
tems for education, little attention has been paid to how stu-
dents actually draw in practice. We examine freely-drawn
digital logic diagrams created by students in an electrical
engineering class in order to inform the design of a sketch
recognition digital circuit simulation tool. Our analysis
reveals considerable drawing style variation between stu-
dents and that standard drawing style restrictions made by
sketch recognition systems to aid recognition generally do
not match the way students draw. We identify drawing be-
