Harnessing Technology: new modes of technology-enhanced learning: opportunities and challenges

A report commissioned by Becta to explore the potential impact on education, staff and learners of new modes of technology enhanced learning, envisaged as becoming available in subsequent years. A generative framework, developed by the researchers is described, which was used as an analytical tool to relate the possibilities of the technology described to learning and teaching activities. This report is part of the curriculum and pedagogy strand of Becta's programme of managed research in support of the development of Harnessing Technology: Next Generation Learning 2008-14. A system-wide strategy for technology in education and skills. Between April 2008 and March 2009, the project carried out research, in three iterative phases, into the future of learning with technology. The research has drawn from, and aims to inform, all UK education sectors

The use of mobile technologies amongst South African commercial farmers

Organisations offering extension services provide services to farmers which include the provision of relevant and current information pertaining to agriculture. The increased use of mobile technologies is changing the way farmers access information, specifically by using the Internet. This paper focuses on South African (SA) commercial farmers who currently use the Internet to establish their Internet access profile, the devices they utilise for Internet access and the purpose for which they use mobile technologies.An Internet and Mobile Device Usage Survey was conducted in the SA agricultural community. Farmers were found to have embraced mobile technology and in excess of 70% of the farmers who participated in the study indicated that they use their mobile devices to access the Internet. No brand of mobile phone or tablet computer was found to dominate the agricultural community. Importantly, close to 50% of respondents indicated that they owned and used a tablet. The primary reason for which mobile devices are used by farmers is for business purposes, including access to information about agriculture. Agricultural organisations offering extension services could benefit from embracing the technology and exploring new ways to provide information services to their farmer base

Improving Clinical Communication and Collaboration Through Technology

Problem: Over the last 30 years, clinical communication methodologies in healthcare have evolved to become such disparate systems that they lead to confusion, wasted time, and clinician dissatisfaction. The Joint Commission (2016) reports up to 78% of sentinel events in hospitals are linked to communication failures, which have obvious implications for hospital systems in the quality and safety of their current communication systems. Context: The purpose of this project was to determine the effectiveness of implementing a unified clinical communication technology platform in an acute care hospital setting and to make recommendations from that implementation to the organization’s larger health system. Its purpose was also to determine if the creation of a clinical communication technology implementation guide for nurse leaders would positively impact future implementations of such platforms throughout the larger health system. Interventions: This project introduced smartphone communication technologies to inpatient nurses and other clinicians in a 352-bed hospital in California, which is part of a larger 39-hospital, multi-state system. Analysis was then performed by collecting data before and after implementation of the clinical communication platform. While not part of the original plan, elements of the platform were subsequently deployed to help with clinical communication during the height of the SARs CoV (COVID-19) pandemic, and this implementation was also analyzed for the project. The intention was also to determine if the creation of a clinically focused implementation guide for clinical leaders could positively impact the application of such a communication platform throughout the larger health system. Measures: Measures in this study included productivity, efficiency, quality of care, communication, and staff satisfaction with the newly implanted technology. Measurement regarding the usefulness of the implementation guide was gauged through the perceived satisfaction of nurse leaders who reviewed the guide and gave feedback. Results: Mixed results were realized from the implementation of this technology, but the work yielded valuable information for future implementations within the organization. Frontline staff and physician satisfaction with the whole platform was low, but leadership satisfaction with the elements implemented for COVID-19 was high. For the implementation guide, nurse leaders gave valuable feedback and determined it would be a highly useful document for facility implementation leads in the future. Conclusion: The implementation of new clinical communication technology and methodologies has the opportunity to improve productivity, efficiency, quality of care, communication, and staff satisfaction, but only if barriers to implementation are mitigated before, during, and immediately after go-live. A comprehensive implementation guide for nurse leaders can be the tool designed specifically to mitigate these barriers and prepare nurse leaders and facilities for the new technology and associated workflow changes that accompany the technology

Co-design of augmented reality textbook for children’s collaborative learning experience in primary schools

Augmented Reality (AR) is a recent technology that allows a seamless composition between virtual objects and the real world. This practice-based research uses the affordances of AR to design an AR textbook for collaborative learning experience. It identifies the key concepts of children s AR textbooks for the designing and evaluation of collaborative learning experiences. These concepts were used to develop a conceptual framework for the AR textbook that considers collaborative experience, learning and usability. Informed by these concepts, the research also has identified the design features which are unique to AR affordances which can be integrated in the school textbooks to develop a collaborative AR textbook for primary school children. The research follows a participatory design approach to involve the users of the AR textbook in the design process. The researcher has conducted three co-design studies involving primary school children and adults using cooperative inquiry techniques. The first study uses low-tech prototyping to find the overall direction of designing the AR textbook. After the development of the first AR textbook prototype, two formative evaluations have been conducted using cooperative inquiry critiquing, and layered elaboration techniques. Throughout these studies, a conceptual framework has been developed namely, Experience, Learn and Use (ELU) for the designing and evaluation of children s AR textbooks for collaborative learning experience. This framework is based on the adaption of Janet Read s Play, Learn, Use (PLU) model that defines children s relationships with the interactive technologies. The research proposes the ELU framework as a useful classification framework in the evaluation process, which informs the design features of the AR textbook which are related to the concepts of collaborative experience, learning and usability. The practical component of the thesis proposes a sample of an AR textbook that is integrated in the regular school curriculum. It demonstrates the design features which can be implemented in other textbooks to support collaborative learning experiences for primary school children. The documentation of the co-design process provides a practical framework for co-designing an AR textbook with children, as well as an evidence of using the ELU framework in practice. 4 This research also contributes in bridging the gap between AR and Child-Computer Interaction (CCI) communities, through the use of common CCI methods in the AR development. This research has resulted in key design principles which contribute original knowledge to the literature of the AR for children s education considering the CCI perspective. These important principles are informed by the collaborative experiences, learning and usability aspects that establish a framework for the design and evaluation of collaborative AR textbook for children. The eight identified principles by this research are, Joint Textbooks, Personalised AR Experience, Interactive AR Book, Communication-Based Learning, Rewarding AR feedback, Audio AR Textbook, Intuitive AR Markers, and Mutual AR Display. The research introduces the definition for each of the concepts and a demonstration of the related design features in the outcome of the AR textbook prototype

Developing a Framework for Stigmergic Human Collaboration with Technology Tools: Cases in Emergency Response

Information and Communications Technologies (ICTs), particularly social media and geographic information systems (GIS), have become a transformational force in emergency response. Social media enables ad hoc collaboration, providing timely, useful information dissemination and sharing, and helping to overcome limitations of time and place. Geographic information systems increase the level of situation awareness, serving geospatial data using interactive maps, animations, and computer generated imagery derived from sophisticated global remote sensing systems. Digital workspaces bring these technologies together and contribute to meeting ad hoc and formal emergency response challenges through their affordances of situation awareness and mass collaboration. Distributed ICTs that enable ad hoc emergency response via digital workspaces have arguably made traditional top-down system deployments less relevant in certain situations, including emergency response (Merrill, 2009; Heylighen, 2007a, b). Heylighen (2014, 2007a, b) theorizes that human cognitive stigmergy explains some self-organizing characteristics of ad hoc systems. Elliott (2007) identifies cognitive stigmergy as a factor in mass collaborations supported by digital workspaces. Stigmergy, a term from biology, refers to the phenomenon of self-organizing systems with agents that coordinate via perceived changes in the environment rather than direct communication. In the present research, ad hoc emergency response is examined through the lens of human cognitive stigmergy. The basic assertion is that ICTs and stigmergy together make possible highly effective ad hoc collaborations in circumstances where more typical collaborative methods break down. The research is organized into three essays: an in-depth analysis of the development and deployment of the Ushahidi emergency response software platform, a comparison of the emergency response ICTs used for emergency response during Hurricanes Katrina and Sandy, and a process model developed from the case studies and relevant academic literature is described

ICS Materials. Towards a re-Interpretation of material qualities through interactive, connected, and smart materials.

The domain of materials for design is changing under the influence of an increased technological advancement, miniaturization and democratization. Materials are becoming connected, augmented, computational, interactive, active, responsive, and dynamic. These are ICS Materials, an acronym that stands for Interactive, Connected and Smart. While labs around the world are experimenting with these new materials, there is the need to reflect on their potentials and impact on design. This paper is a first step in this direction: to interpret and describe the qualities of ICS materials, considering their experiential pattern, their expressive sensorial dimension, and their aesthetic of interaction. Through case studies, we analyse and classify these emerging ICS Materials and identified common characteristics, and challenges, e.g. the ability to change over time or their programmability by the designers and users. On that basis, we argue there is the need to reframe and redesign existing models to describe ICS materials, making their qualities emerge

Understanding and designing for control in camera operation

Kameraleute nutzen traditionell gezielt Hilfsmittel um kontrollierte Kamerabewegungen zu ermöglichen. Der technische Fortschritt hat hierbei unlängst zum Entstehen neuer Werkzeugen wie Gimbals, Drohnen oder Robotern beigetragen. Dabei wurden durch eine Kombination von Motorisierung, Computer-Vision und Machine-Learning auch neue Interaktionstechniken eingeführt. Neben dem etablierten achsenbasierten Stil wurde nun auch ein inhaltsbasierter Interaktionsstil ermöglicht. Einerseits vereinfachte dieser die Arbeit, andererseits aber folgten dieser (Teil-)Automatisierung auch unerwünschte Nebeneffekte. Grundsätzlich wollen sich Kameraleute während der Kamerabewegung kontinuierlich in Kontrolle und am Ende als Autoren der Aufnahmen fühlen. Während Automatisierung hierbei Experten unterstützen und Anfänger befähigen kann, führt sie unweigerlich auch zu einem gewissen Verlust an gewünschter Kontrolle. Wenn wir Kamerabewegung mit neuen Werkzeugen unterstützen wollen, stellt sich uns daher die Frage: Wie sollten wir diese Werkzeuge gestalten damit sie, trotz fortschreitender Automatisierung ein Gefühl von Kontrolle vermitteln? In der Vergangenheit wurde Kamerakontrolle bereits eingehend erforscht, allerdings vermehrt im virtuellen Raum. Die Anwendung inhaltsbasierter Kontrolle im physikalischen Raum trifft jedoch auf weniger erforschte domänenspezifische Herausforderungen welche gleichzeitig auch neue Gestaltungsmöglichkeiten eröffnen. Um dabei auf Nutzerbedürfnisse einzugehen, müssen sich Schnittstellen zum Beispiel an diese Einschränkungen anpassen können und ein Zusammenspiel mit bestehenden Praktiken erlauben. Bisherige Forschung fokussierte sich oftmals auf ein technisches Verständnis von Kamerafahrten, was sich auch in der Schnittstellengestaltung niederschlug. Im Gegensatz dazu trägt diese Arbeit zu einem besseren Verständnis der Motive und Praktiken von Kameraleuten bei und bildet eine Grundlage zur Forschung und Gestaltung von Nutzerschnittstellen. Diese Arbeit präsentiert dazu konkret drei Beiträge: Zuerst beschreiben wir ethnographische Studien über Experten und deren Praktiken. Sie zeigen vor allem die Herausforderungen von Automatisierung bei Kreativaufgaben auf (Assistenz vs. Kontrollgefühl). Zweitens, stellen wir ein Prototyping-Toolkit vor, dass für den Einsatz im Feld geeignet ist. Das Toolkit stellt Software für eine Replikation quelloffen bereit und erleichtert somit die Exploration von Designprototypen. Um Fragen zu deren Gestaltung besser beantworten zu können, stellen wir ebenfalls ein Evaluations-Framework vor, das vor allem Kontrollqualität und -gefühl bestimmt. Darin erweitern wir etablierte Ansätze um eine neurowissenschaftliche Methodik, um Daten explizit wie implizit erheben zu können. Drittens, präsentieren wir Designs und deren Evaluation aufbauend auf unserem Toolkit und Framework. Die Alternativen untersuchen Kontrolle bei verschiedenen Automatisierungsgraden und inhaltsbasierten Interaktionen. Auftretende Verdeckung durch graphische Elemente, wurde dabei durch visuelle Reduzierung und Mid-Air Gesten kompensiert. Unsere Studien implizieren hohe Grade an Kontrollqualität und -gefühl bei unseren Ansätzen, die zudem kreatives Arbeiten und bestehende Praktiken unterstützen.Cinematographers often use supportive tools to craft desired camera moves. Recent technological advances added new tools to the palette such as gimbals, drones or robots. The combination of motor-driven actuation, computer vision and machine learning in such systems also rendered new interaction techniques possible. In particular, a content-based interaction style was introduced in addition to the established axis-based style. On the one hand, content-based cocreation between humans and automated systems made it easier to reach high level goals. On the other hand however, the increased use of automation also introduced negative side effects. Creatives usually want to feel in control during executing the camera motion and in the end as the authors of the recorded shots. While automation can assist experts or enable novices, it unfortunately also takes away desired control from operators. Thus, if we want to support cinematographers with new tools and interaction techniques the following question arises: How should we design interfaces for camera motion control that, despite being increasingly automated, provide cinematographers with an experience of control? Camera control has been studied for decades, especially in virtual environments. Applying content-based interaction to physical environments opens up new design opportunities but also faces, less researched, domain-specific challenges. To suit the needs of cinematographers, designs need to be crafted with care. In particular, they must adapt to constraints of recordings on location. This makes an interplay with established practices essential. Previous work has mainly focused on a technology-centered understanding of camera travel which consequently influenced the design of camera control systems. In contrast, this thesis, contributes to the understanding of the motives of cinematographers, how they operate on set and provides a user-centered foundation informing cinematography specific research and design. The contribution of this thesis is threefold: First, we present ethnographic studies on expert users and their shooting practices on location. These studies highlight the challenges of introducing automation to a creative task (assistance vs feeling in control). Second, we report on a domain specific prototyping toolkit for in-situ deployment. The toolkit provides open source software for low cost replication enabling the exploration of design alternatives. To better inform design decisions, we further introduce an evaluation framework for estimating the resulting quality and sense of control. By extending established methodologies with a recent neuroscientific technique, it provides data on explicit as well as implicit levels and is designed to be applicable to other domains of HCI. Third, we present evaluations of designs based on our toolkit and framework. We explored a dynamic interplay of manual control with various degrees of automation. Further, we examined different content-based interaction styles. Here, occlusion due to graphical elements was found and addressed by exploring visual reduction strategies and mid-air gestures. Our studies demonstrate that high degrees of quality and sense of control are achievable with our tools that also support creativity and established practices

Technology for a Smarter Planet: The Role of Cognitive Technologies and Open Innovation.

Information technology is making the human race smarter by increasing its cognitive capacity through at least two drivers: Open Innovation and cognitive computing. Open innovation allows leveraging the wisdom of the crowds by bringing in more people into the fold through open innovation platforms, open source development and citizen science. In this sense, open innovation is enabling harnessing of the latent cognitive surplus of the human race. The dawn of the cognitive computing era on the other hand, is affording new uses of computers in organizational decision making. Specifically, IT is now enabling organizations to scan, interpret and learn from larger subsets of their informational environment hitherto considered inaccessible and un-interpretable by computers. As organizations and individuals gain this sixth sense of sorts, they can make better resource allocation decisions. In my dissertation, I study both these technology developments and their role in making organizations smarter and thus better generators of value. The underlying motivation is that better organizational decisions will allow better use of scarcer resources making the planet more sustainable. In chapter 2, a purposive theoretical framework for synthesizing the role of IT in organizational decision making is attempted. The proposed interpretive model of IT, also achieves a clear delineation between the programmable and cognitive computing eras. In chapter 3, the antecedents of predictive analytics usage within firms are explored through an empirical study. In chapter 4, an empirical study of the idea selection process within an open innovation funnel is undertaken to explore the question whether open innovation funnels prefer innovative ideas over conservative ideas.PhDBusiness AdministrationUniversity of Michigan, Horace H.
