Disciplinary boundaries become increasingly unclear when grappling with “wicked problems,” which present a complex set of policy, cultural, technological, and scientific dimensions. “T-shaped” professionals, i.e. individuals with a depth and breadth of expertise, are being called upon to play a critical role in complex problem-solving. This paper unpacks the notion of the “T-shaped expert” and seeks to situate it within the broader academic literature on expertise, integration, and developmental learning. A component of this project includes an exploratory study, which is (...) aimed at evaluating the emergent attributes of T-shaped expertise in two different educational programs completed between January and May in 2015. The two programs build disciplinary knowledge in science, technology engineering, and mathematics fields at the core, while expanding the students’ awareness and comprehension of other expertise. The courses introduced science and engineering students to case study topics focusing around complex human-technological-ecological systems in a nanotechnology and society course; and the governance of genetically modified organisms in a science, technology, and society course. We analyze pre- and post-test data from this pilot project before presenting findings that pertain to student learning, as well as variants in the methodology and reflect on the utility of the selected methodology for evaluating expertise as it evolves over time. The paper closes with a discussion of a theory of acquisition with implications for delineating early attributes and characteristics of T-shaped expertise. (shrink)

Jean Ayres invented Sensory Integration for children experiencing learning and social difficulties because, according to Ayres, they could not adequately integrate information from multiple sensory modalities. She established a scientific basis for her identification of children with sensory integrative difficulties, using statistical techniques to identify symptoms and neuroscience to determine a cause. She was an unusually reflective practitioner who catalyzed a community of practice around SI without becoming a guru—indeed, she encouraged her students to come up with their own ideas (...) and test them empirically. She felt isolated from the growing field of Occupational Therapy yet is viewed as one of its greatest pioneers. After her death in 1988, the SI community gradually began to argue about fundamental issues like what should constitute an appropriate diagnosis and set of tests for SI. At present, the network is fragmented to the point where some of the opposing positions may be incommensurable with each other, which would require a trading zone. (shrink)
