I am interested in the learning processes that go on in hands-on professional training domains, and how to design digital technology to help people acquire professional skills. In my dissertation research, I am conducting a multi-year ethnography-for-design project at a local dental hygiene training program looking at how new students develop expertise in instrumentation skills during hands-on training in a clinical laboratory. I have helped the school design a new clinical training laboratory, equipped with a variety of digital media technology, such as embedded monitors and overhead cameras. I am investigating how digital imaging and video technology affect how novices develop the complex skill set (perceptual, manual and conceptual) required of expert dental hygienists. In order to create successful technology for teaching expert skills, it is important to understand the learning effects of certain kinds of representations, media, and instructional strategies. Research methods are informed by ethnography-for-design and contextual design [11], situated in a framework provided by distributed cognition theory [12].
