TY - JOUR T1 - Abduction to Argument: A Framework of Design Thinking JF - Landscape Journal SP - 127 LP - 138 DO - 10.3368/lj.34.2.127 VL - 34 IS - 2 AU - Allan W. Shearer Y1 - 2016/03/09 UR - http://lj.uwpress.org/content/34/2/127.abstract N2 - This paper presents a constructivist framework for design thinking based on the recognition that there are different kinds of generative propositions. Five different “What if … ?” questions are identified. It is offered that subsequent design development occurs in two ways. First, intensive development seeks an increasingly precise understanding of a proposed change by refining the generative proposition with respect to the initial “What if … ?” question. Second, extensive development seeks an increasingly comprehensive understanding of a proposed change by applying, adapting, and adjusting the generative proposition with respect to the other “What if … ?” questions. It is suggested that when both kinds of design development are performed successfully, the generative proposition of change becomes a reasoned argument for change. ER -
