Abstract

More than 60% of older Americans have sedentary lifestyles1 and are recommended more physical activities for health benefit. Nearby outdoor environments on residential sites may impact older inhabitants׳ physical activities there (defined as walking, gardening, yard work, and other outdoor physical activities on residential sites). This study surveyed 110 assisted-living residents in Houston, Texas, regarding their previous residential sites before moving to a retirement community and physical activities there. Twelve environmental features were studied under four categories (typology, motivators, function, and safety). Based on data availability, a subset of 57 sample sites was analyzed in Geographic Information Systems. Hierarchical linear modeling was applied to estimate physical activities as a function of the environments. Higher levels of physical activity were found to be positively related with four environmental features (transitional-areas, connecting-paths, walk-ability, and less paving).

Abstract

This paper presents design thinking as an alternative approach to conduct research on collaborative learning with technology. The underlying premise of the paper is the need to adopt human-centered design principles in research and design of computer-supported collaborative tools. Two research results are described in order to discuss the possibilities and challenges of applying design methods for designing and researching collaborative knowledge building tools. The paper begins by defining collaborative learning with new technologies as a wicked problem that can be approached by adopting a design mindset. Design thinking and particularly research-based design relies on a shared, social construction of understanding with the people who will later use the tools. The key phases in researchbased design (contextual inquiry, participatory design, product design and software as hypothesis) are described and exemplified through the presentation of two research results. The two prototypes presented are the fourth version of the Future Learning Environment (Fle4), a software tool for collaborative knowledge building and Square1, a set of hardware and software for self-organized learning environments. Both cases contribute to the discussion about the role of artifacts as research outcomes. Through these cases, we claim that design thinking is a meaningful ap proach in CSCL research.
