In order to understand how technical artifacts are attuned to, interacted with, and
shaped in various and varied classrooms, it is necessary to construct detailed accounts of the
use of particular artifacts in particular classrooms. This paper presents a descriptive account of
how a shared workspace was brought into use by a student pair in a face-to-face planning task.
A micro-developmental perspective was adopted to describe how the pair established a
purposeful connection with this unfamiliar artifact over a relatively short time frame. This
appropriation was examined against the background of their regular planning practice. We
describe how situational resources present in the classroom—norms, practices and artifacts—
frame possible action, and how these possibilities are enacted by the pair. Analysis shows that
the association of norms and practices with the technical artifact lead to a contradiction that
surfaced as resistance experienced from the artifact. This resistance played an important part in
the appropriation process of the pair. It signaled tension in the activity, triggered reflection on
the interaction with the artifact, and had a coordinative function. The absence of resistance was
equally important. It allowed the pair to transpose or depart from regular procedure without
reflection
