Transdisciplinary - STEAM Design Toolkit: Leveraging the Benefits of Artistic Approaches in Multidisciplinary Collaborations

Abstract

Complex global challenges such as climate change, technological disruption, and social inequality increasingly require collaboration across disciplinary boundaries. While STEAM (Science, Technology, Engineering, Arts, and Mathematics) initiatives promise richer perspectives and innovative solutions, assembling and sustaining transdisciplinary design teams that successfully integrate diverse epistemologies remains difficult. Disciplinary co-presence alone does not guarantee integration; carefully designed epistemic and relational conditions are required. This dissertation addresses this challenge through a seven-year longitudinal action research study conducted in higher education design courses. It argues that art and artistic practices, when authentically integrated with other disciplines, enhance the transformative capacity of transdisciplinary STEAM collaborations. Across seven iterative Plan–Act–Observe–Reflect cycles, the research developed and refined the Transdisciplinary STEAM Design Toolkit (TD-SDT) —a framework conceived not as a prescriptive method but as an epistemic infrastructure designed to enable transdisciplinary knowledge creation. Empirical analysis revealed that effective transdisciplinary collaboration depends on three interacting conditions: epistemic conditions which encourage reflexive examination of disciplinary assumptions, relational conditions which sustain trust and enable productive friction, and pedagogical conditions which scaffold collaborative inquiry through structured design processes. Within such environments, integration occurs through mechanisms of epistemic crossing, a process through which participants move beyond disciplinary perspectives to construct shared conceptual spaces. Key epistemic mediators include abstraction, narrative reframing, boundary objects, artistic inquiry, and symbolic infrastructures. Methodologically, the study introduces the TD Process Assessment Framework, a structured yet complexity-sensitive approach for evaluating both collaborative process quality and integration depth. The framework combines quantitative assessment of transdisciplinary dimensions with qualitative triangulation across artifacts, reflections, and observational data. Theoretically, the TD-SDT operationalises a Constructivism–Systems Thinking–Complexity (CSC) framework and extends reflexivity-based models of collaboration toward the concept of epistemic innovation, describing how new integrative understandings emerge through sustained epistemic crossing. The findings also reposition the arts as epistemic infrastructure within STEAM collaboration, demonstrating their role in sustaining ambiguity, activating productive friction, and enabling epistemic movement across disciplinary boundaries. Together, these contributions advance a coherent model for cultivating transdisciplinary collaboration in complex design contexts and provide educators, researchers, and practitioners with both conceptual guidance and an assessable infrastructure for supporting integrative knowledge creation.
