Björling University of Washington Tacoma University of Washington Tacoma, WA Sea!lee, WA USA USA [email protected] [email protected] ABSTRACT technologies [51, 75, 81], researchers and designers need to consider how to design for engagement between people and While scholars in technical communication have examined on things [5].

In this research article, we present [61]. findings from a project investigating the possibility of designing Although the SIGDOC community has focused on designing a social robot to help measure teen stress. To explore design communication across a variety of domains, little work has possibilities, we conducted a series of participatory design specifically ventured into how to design interactions with social sessions with teens to envision the design of a social robot to robots. Studying how to design the interactions between humans measures stress. The findings from the study include how teens and robots is seen as qualitatively different from the field of react to existing robots, how teens conceptualize robots that human-computer interaction and therefore has spawned the sub might live in their schools through storyboarding and group field of human-robot interaction [26]. Scholars in technical discussion, and reactions to an emerging design of a low fidelity communication have considered the impact of theoretical robot. In our discussion, we reflect on implications for designing approaches of new materialism and post humanism to design social robots for and with teens, considerations for studying [44, 46, 61]; however, there is a lack of empirical work in our engaging relationships, and reflections on methodological field that examines the interactions between human and non- choices of participatory design. human agents, in the form of social robots, and how to design an engaging relationship between the two.

BACKGROUND Ecological momentary assessment and experience sampling In this section, we situate our research by providing background have been shown to be extremely successful in capturing data on the issue of teens and stress, the challenges of accurately from adolescents [20, 36, 68, 74]. However, capturing data measuring stress, and an overview of applications and repeatedly in a busy school setting requires both novelty and approaches for designing social robots and issues of engagement. engagement that moves beyond current research tools found in static, ordinary smart phones and tablets. Therefore, the 2.1 Teen stress challenge for accurately gathering data from teens in a school setting requires an approach that moves beyond just designing Although a great deal of research has been conducted in the field for individual use.

  • The Dilemma of Education in Participatory Design: the Marketplace Value Vs
    Session 1725 The Dilemma of Education in Participatory Design: The Marketplace Value vs. Community Value Kun-Jung Hsu Department of Construction Technology Leader University, Taiwan. Abstract The concept of “participatory planning/design” has gradually become one of the main themes in professional design and social science. However, because behavioral patterns in space design are closely related to the values of the designers concerned, the pursuit and construction of a good place is a basic and normative proposition in the proceeding of planning and design. This paper explores the dilemma of education in participatory design and reveals the contradiction between marketplace values and community values in practice. Also, this paper utilizes the production possibility curve and the choice theory of demand side to analyze the concept, value judgment, decision-making, and constraints of planning/design behavior. Introduction The ideal of advocacy planning first proposed by Davidoff in the mid 1960’s. The professional planners and designers who support this view vow to make planning for the needs of the disadvantaged groups and persons their top priority. They jointly opposed urban redevelopment policy propelled by bulldozers, and advocated the development of participatory planning methods through democratic processes. The normative discourse proposes that public space planning and design be regarded as requiring direct public participation in the decision-making processes in formulating public space. Environment-Behavior study (E-B study) adopts problem-oriented approaches that emphasize the need for interaction between design and research [6]. Following the development of E-B Study, the normative viewpoint of participatory planning and design has gradually become one of the main themes in professional design and social science [3, 7, 8].

  • Participatory Design of Classrooms: Infrastructuring Education Reform in K-12 Personalized Learning Programs
    Journal of Learning Spaces Volume 7, Number 2. 2018 ISSN 21586195 Participatory Design of Classrooms: Infrastructuring Education Reform in K‐12 Personalized Learning Programs Julie M. Kallio University of Wisconsin ‐ Madison The redesign of the physical spaces of classrooms and schools has become a prominent feature in many K‐12, personalized learning schools, though it is often dismissed as a peripheral aspect of change. Through observations and interviews at four public schools, I examine the affordances of these new spaces and the narrative of their design. I situate these spaces‐turned‐places as pedagogical artifacts in a participatory design process to examine how educators and students create functional and meaningful learning spaces. Reframing the physical spaces in this way suggests how the spaces may be supporting the sustainability of the reform. In an ongoing inquiry into personalized learning (PL) educational reform that redesigns school systems to support reforms in urban, suburban, and rural districts, I heard student‐centered, agency‐based models of learning educators and students speak at length, often unprompted, (Rickabaugh, 2016). PL draws on progressive ideas of about the ways they had modified their classrooms and engaging students as agents in their own learning with the buildings, from knocking down walls to adding sofa chairs support of digital technologies (Patrick, Kennedy, & Powell, and lamps (Author, et al., 2015). To them, their physical 2013).

  • Environmental Justice + Landscape Architecture: a Student's Guide
    ENVIRONMENTAL JUSTICE LANDSCAPE ARCHITECTURE a students’ guide This guide was written by three masters of landscape architecture students who wanted to learn more about how landscape architecture can promote social justice and equity through design. In 2016 we became the student representatives for the ASLA's Environmental Justice Professional Practice Network so we could better connect the important work of professionals, academics, and activists working towards environmental justice with students. This guide is a response to our own desires to educate ourselves about environmental justice and share what we learned. It is a starting-off place for students - a compendium of resources, conversations, case studies, and activities students can work though and apply to their studio projects. It is a continuously evolving project and we invite you to get in touch to give us feedback, ask questions, and give us ideas for this guide.

This increasing interaction among people from diverse cultures has produced a complex ethno-cultural mosaic that presents formidable challenges for visual communication designers’ as well to other designers. Complexity has always been part of human environments that comprises of mutually dependent social relations. Cultural diversity of designers and audience of messages in a design scenario brings complexity in the design research process.

    Brownfields in the Classroom: Partnering with your Local University LANDCAPE ARCHITECTURE PERSPECTIVES Peter Butler Assistant Professor of Landscape Architecture Davis College of Agriculture, Natural Resources and Design West Virginia University Definition and Engaged Scholarship Participatory design (originally known as 'Co-operative Design') is an approach to design that attempts to actively involve all stakeholders (e.g. employees, partners, customers, citizens, end users) in the design process to help ensure that the product designed meets their needs and is usable. The term is used in a variety of fields e.g. software design, urban design, architecture, landscape architecture, product design, sustainability, project design, planning or even medicine as a way of creating environments that are more responsive and appropriate to their inhabitants' and users' cultural, emotional, spiritual and practical needs. The key attribute of participatory design is that it is a process which allows multiple voices to be heard and involved in the design, resulting in outcomes which suit a wider range of users. history- characteristics A defined methodology and systematic learning process.
