Major Depressive Disorder (MDD) and Posttraumatic Stress Disorder (PTSD) are highly prevalent illnesses that can result in profound impairment. While many patients with these disorders present in primary care, research suggests that physicians under-detect and suboptimally manage MDD and PTSD in their patients.

Major Depressive Disorder (MDD) and Posttraumatic Stress Disorder (PTSD) are highly prevalent illnesses that can result in profound impairment. While many patients with these disorders present in primary care, research suggests that physicians under-detect and suboptimally manage MDD and PTSD in their patients. The development of more effective training interventions to aid primary care providers in diagnosing mental health disorders is of the utmost importance. This research focuses on evaluating computer-based training tools (Avatars) for training family physicians to better diagnose MDD and PTSD. Three interventions are compared: a "choice" avatar simulation training program, a "fixed" avatar simulation training program, and a text-based training program for training physicians to improve their diagnostic interviewing skills in detecting and diagnosing MDD and PTSD. Two one-way ANCOVAs were used to analyze the differences between the groups on diagnostic accuracy while controlling for mental health experience. In order to assess specifically how prior mental health experience affected diagnostic accuracy the covariate of prior mental health experience was then used as an independent variable and simple main effects and pairwise comparisons were evaluated. Results indicated that for the MDD case both avatar treatment groups significantly outperformed the text-based treatment in diagnostic accuracy regardless of prior mental health experience. For the PTSD case those receiving the fixed avatar simulation training more accurately diagnosed PTSD than the text-based training group and the choice-avatar training group regardless of prior mental health experience. Confidence ratings indicated that the majority of participants were very confident with their diagnoses for both cases. Discussion focused on the utility of avatar technology in medical education. The findings in this study indicate that avatar technology aided the participants in diagnosing MDD and PTSD better than traditional text-based methods employed to train PCPs to diagnose. Regardless of experience level the fixed avatar group outperformed the other groups for both cases. Avatar technology used in diagnostic training can be user-friendly and cost-effective. It can also have a world-wide reach. Additional educational benefit could be provided by using automated text analysis to provide physicians with feedback based on the extent to which their case diagnostic summaries cover relevant content. In conclusion, avatar technology can offer robust training that could be potentially transferred to real environment performance.

Expansive framing is a promising approach to understanding transfer but little is known about how it might work in teacher professional development, an area that research suggests would be improved by the use of situative strategies. The Content, Person, Context framework (CPC) that has been developed in online learning contexts draws on the concept of expansive framing and further develops it through a focus on positioning content, person and context for value creation. However, little is known about how it promotes transfer. I studied how these two situative approaches, individually and together, illuminated near-transfer in the context of an online teacher professional development (PD) course. In this mixed methods study I adapted and created rubrics to analyze educators’ stories about how they intended to implement what they had learned in the course. I concluded that CPC and expansive framing support different understandings of authorship, with the former prioritizing immediate action planned for specific contexts and the latter emphasizing learner creation and ownership over time. These different views have consequences for how transfer is understood but can be used to create a model of how transfer can be fostered that is more robust than either framework taken on its own. Because this study is part of an evaluation phase of an ongoing design-based research project, I make recommendations for how expansive framing and CPC can be further used as tools for designing the next iteration of the PD module.

In this three-article dissertation, I explore what it means for teachers to be designers in three different ways. Each article can stand on its own, but taken together, they paint a rich and nuanced picture of the relationship between teachers and design. The first article is an analysis of a decade of literature on teachers and design seeking to answer the question, “What does it mean for a teacher to be described as a designer, or for the act of teaching to be considered an act of design?” The analysis combined an interpretive content analysis of central terms and constructs with a network analysis of co-authorship and citation practices. The results highlighted 10 strands of literature around teachers and design, each describing a different perspective on what, how, when, and why teachers design. The second article focuses on a design-based professional development (PD) program I conducted with four teachers in a rural junior high school. The program was designed to support teachers in approaching problems of practice in designerly ways, including exploring problems using various epistemic perspectives. Using an embedded case analysis approach, I found that although each teacher interpreted the program differently, all described outcomes related to coming to know in new ways, developing a deeper understanding of students, and being impacted at a personal level. These outcomes could be interpreted as a type of sensemaking, where teachers came to re-interpret the past and present in ways that allowed them to shape the future. Sensemaking was supported through epistemic diversity and the acts of framing common in design practice. The third article is a scholarly essay arguing that the PD program and its implementation suggest design is not only about creating things but is also about seeing and addressing the indeterminacy inherent in complex situations of practice. Designers interact with this indeterminacy through imposing a frame on the situation and interpreting the results. When teachers are designers, they are empowered to integrate their personal and professional selves with the design situation, all while maintaining a form of skeptical optimism within complex and shifting contexts.
