    VaDeR: Visualizing a Development Record A Study of Claims-Centric Scenario-Based Design
    Berry, Brandon (Virginia Tech, 2004-06-28)
    The scenario-based design process, particularly with an emphasis on claims, captures and shares design knowledge that has promise in teaching design. However, the best methods are not fully understood yet. This thesis examines the areas of scenario-based design, claims relationships, and learning through cases with the goal of learning what can be improved to better support these processes. In investigating those areas, an information visualization tool is created for learning design through case studies. The tool combined claims from multiple visualization techniques to create an approach for supporting problem-based learning goals. In creating the tool, scenario-based design was used, with a particular emphasis on claims for driving the development and evaluation. All design rationale was captured in claims to create a tool that addressed the current problem issues identified. A recently developed claims relationship framework, used for the first time in development efforts, aided in structuring the design rationale. Using these relationships, the design was tracked from requirements analysis to problem claims to design claims and finally to claims that formed the basis of an evaluation. This thesis presents a case study of using claims relationships to drive the development and evaluation of a tool for supporting problem-based learning through case studies of scenario-based design. In creating a novel tool for learning about cases, a unique example of claims-centric scenario based design emerges, presenting as open questions new directions for merging scenarios, claims, and cases in knowledge storage, access, and learning systems.

    Visualizing Case Studies
    Berry, Brandon; Smith, Jamie; Wahid, Shahtab (Department of Computer Science, Virginia Polytechnic Institute & State University, 2004)
    Case studies contain valuable information about development records. They are, however, usually presented as textual documents. Here we begin an initial design for viewing case study data. A prototype for viewing case study data is created using information visualization techniques for the purpose of testing against existing techniques. The evaluations show that the new design is just as usable as existing techniques, making it suitable for future development. Future work may show our design can accomplish tasks both faster and more efficiently.
