Information Technology Support for Communities of Practice: How Public Defenders Learn about Winning and Losing in Court

The aim of this article is to examine the role of information technologies (IT) in supporting practice and professional identity formation, both major axes for communities of practice.

The concept of “communities of practice” helps to illuminate how the attorneys in a public defender’s office share knowledge in order to practice effectively in court. This article presents findings that a community of practice serves as effective scaffolding to support professional development; this is especially true for the practice component.
