This paper describes the Research Communications Studio (RCS), a structured approach for teaching undergraduate researchers to do authentic written, oral, and graphical communications tasks while they are learning to do research. In the RCS, small groups of undergraduate researchers meet weekly with a communications faculty member, an engineering graduate student mentor, and a communications graduate research assistant. The project is built upon social constructivist theory that recognizes the interdependence between communication, cognitive development, and metacognition. It investigates knowledge construction within a small-group context of distributed cognition, the concept that each group member's expertise is available to other group members. Data from surveys indicate that engineering faculty members, graduate student mentors, and undergraduate participants were very positive about the progress participants made in cognitive development and communications abilities. Analysis of participants' reflective writings shows the development of metacognitive abilities necessary for self-directed, life-long learning.
