Design thinking has an important role in STEM education. However, there has been limited research on how students engage in various modalities throughout the design process in hands-on design tasks. To promote middle school students’ engineering literacy, it is necessary to examine the use of design modalities during design. Using a case study approach, we examine middle school students’ design stages and modalities during design activities. We also identify the patterns of design processes in the teams with different design outcomes. Drawing on theories in design thinking and embodied interaction, we proposed a framework and devised a video analysis protocol to examine students’ design stages and modalities. Middle school students attending a design workshop engaged in two design activities in teams of 3–4 people. The design sessions were video recorded and analyzed using the video analysis protocol. The teams engaged in the stages of planning, building, and testing, while employing the verbal, the visual, and the physical modalities. The teams that varied in design outcomes exhibited different patterns in the use of multiple modalities during the design stages. This study contributes to research on design thinking by proposing a framework for analyzing middle school students’ multimodal design processes and presenting data visualization methods to identify patterns in design stages and modalities. The findings suggest the necessity to examine students’ use of design modalities in the context of design stages and imply the potential benefits of using multiple modalities during design. The implications for future research and education practices are also discussed.

Educational researchers are increasingly using design as a means of advancing their understanding. Historically design in educational research has served as a way to implement theories for testing. The emerging design research paradigm treats design as a strategy for developing and refining theories. In this article, I discuss the lessons that can be learned from design. Starting from a model that characterizes designs in terms of problem analyses, design solutions, and design processes, I describe 3 types of theories that can be developed through design research: domain theories, design frameworks, and design methodologies. I present examples from a design research program investigating software supports for reflective inquiry. I argue for design research as form of educational research because (a) design offers opportunities to learn unique lessons, (b) design research yields practical lessons that can be directly applied, and (c) design research engages researchers in the direct improvement of educational practice. 相似文献

An international education opportunity has been created for design students at West Virginia University. This experience is unique because it takes an interdisciplinary approach to design that exposes students to the idea of a larger design methodology common to design professions. Students take core courses with students from a variety of design fields, including interior design, fashion design, fashion merchandising, landscape architecture, art, and graphic design. Through this interaction, students gain an understanding of the interrelationships among design fields, learn to appreciate new perspectives, and begin to appreciate the place of their field as part of the design community as a whole. 相似文献

The notion of design thinking is becoming more concrete nowadays, as design researchers and practitioners study the thinking processes involved in design and employ the concept of design thinking to foster better solutions to complex and ill‐defined problems. The goal of the present research is to develop a cognitive activity‐based design methodology for novice visual communication designers, which will be achieved by mapping the findings from a comparative analysis of novice and expert visual communication designers' thinking processes onto the prospective methodology. Under the proposed methodology, activity modes take place in a chronological flow under specific guidelines involving various forms of design cognition. The guidelines correlate to design phases from problem structuring to detailed design and to the cognitive processes of divergent and convergent thinking. The methodology gives open‐ended instruction to novices endeavouring to proceed with the design process, solve complex design problems and make better design decisions. This research has value for its unique approach to methodology development. Furthermore, the proposed methodology provides guidance for more effective cognitive activities during the design process and holds potential for implementation in design education due to its focus on the needs of novice designers. 相似文献
