HYPERCONNECTED SCHOOL LEADERSHIP: SHARED EXPERIENCES

Leaders remain perpetually connected to their work because of the rapid advancement of information technology. This research, using a qualitative approach, explored how increased connective technology is affecting school leaders with the central question: How is hyperconnectivity experienced by school leaders? Using personal interviews, the lived experiences of fifteen international middle and high school principals with one-to-one student-to-device programs were collected. Raw transcriptions of their experiences were analyzed using the descriptive phenomenological approach as outlined by Giorgi (2009). This approach allowed for the data to be reduced into a single narrative description shared by all participants indicating the essences of their lived experience as hyperconnected school leaders. This shared narrative highlighted complex and paradoxical experiences associated with how these school leaders interact with technology. Their experiences indicated that work-life balance for hyperconnected leaders required strong personal boundaries and skillful use of connective technologies. Examples of effective leader development of self and community highlighted, paradoxically, the need to unplug to effectively deploy connected technology within their leadership practice. Conversely, this study also showed how leaders can be controlled by connectivity. They associated their roles as responsible school leaders with perpetual connectivity; in consequence, they fused their work and home lives, experienced increased stress, and struggled with work overload. These results imply that international school principals are impacted by increased connectivity in different ways. Findings from this study indicate those leading hyperconnected schools must pay attention to how connectivity is affecting themselves and members of their school communities. Principals must protect themselves from the increasing demands upon their attention that constant connectivity presents in order to make mental room for the self-reflection and creativity needed to provide novel solutions and approaches towards their leadership work

Web Content Management System and accessibility awareness: A comparative study of novice users and accessibility outcomes

Since its creation, the Web has progressively developed and become a vital source of information in every domain and for almost all people. It is crucial to guarantee that the information contained on the Web is available for everyone, especially for people with special needs. Removing accessibility barriers is fundamentally based on tools, skills and support of all contributors, particularly the content creators, to ensure information is navigable and usable in the context of the end users experience. Web Content Management Systems play a significant role in structuring, storing and provision content to the Web and have evolved to address the difficulties of manually coding web pages versus the convenience of manipulating their content without any programing skills. Web Content Management Systems have gradually evolved to contain features and functions that allow content authors to shape their content in ways that address web content accessibility expectations, though only if the content author knows how to use these features to maximum effect. This thesis explores such usage by participants deemed to be novices, in that they have limited technical skills in the context of web coding and have limited expose to Web Content Management Systems or the application/awareness of the Web Content Accessibility Guidelines (WCAG). This research places an emphasis on the outcome of these novice users when provided with some basic training and awareness raising of WCAG principles and the use of a modern Web Content Management System. This is explored in the literature as an area of some importance as organisations with significant web presence cannot simply tell their content authors to ‘oh, and make sure it is accessible’ and hope that the end product will somehow achieve that goal without an investment in some form of accessibility education. For web managers and developers in all public sector organisations. “Make sure that all content commissioners and authors are fully trained in the importance of accessible content, and in the means that are made available for them to achieve this . (p. 58) The purpose of this research was to explore to what level the use of accessible Web Content Management System and novice users’ training impacted accessibility outcomes. This study emerged from the widespread role that Web Content Management Systems play in terms of storing and managing web content and the growing usage of these systems by experts or novices at an organisational or personal level. Through a selection process, this study identified a Web Content Management System that had a number of accessibility features, developed some training and ‘awareness raising’ materials and then asked novice users across two groups to apply what they had learned in order to develop an accessible website. The goal of the study was to ascertain if the two groups performed differently according to the training and awareness raising materials they received, and if even basic accessibility outcomes were achievable with just a few hours of training and from what was essentially an accessibility ‘cold start’. The study used a mixed methods approach encompassing three research methods; experimental method, survey method and observational method, to compare qualitative and quantitative data obtained from ‘accessibility awareness’ and ‘accessibility unaware’ participant groups. Thirty university students participated in this research and received accessibility awareness raising sessions, with additional accessibility-related examples for the accessibility awareness group. All participants undertook pre and post-tests that were designed to collect data allowing the researcher to compare the learning performance before and after the participants’ awareness session. At the end of the awareness session, the participants of both groups completed a survey which was designed to provide further data on the participant’s perception of web use and experience, the concept of web accessibility, web content accessibility guidelines, the system used, and their opinion of the accessibility awareness session. Data collected from the survey, pre and post-tests and the recording provided a holistic set of data from which the primary and supporting research questions were addressed. The results of the research indicated that the accessibility awareness group demonstrated measurably better accessibility outcomes than the unawareness group; these results being attributed to the awareness training session, participants’ searching behaviour, time spent on tasks, and effort made to implement accessible features and complete the required tasks. The participants in both groups had some prior knowledge in the use of the Web but limited or no skills in HyperText Markup Language (HTML) or the use of a Web Content Management System. While performing tasks, the participants in the awareness group attempted to apply the accessibility concepts learnt during the training session and spent more time in searching those concepts on the Web in order to provide accessible web page content. Conversely, most of the participants in the unawareness group were concerned by the “look” of the web page, rather than focusing on actual accessible content; they only mimicked the exemplar website they have been provided as an ‘end product’, but did not explore the how and why of accessible content. All the participants at the end of this study were aware of the significance of web accessibility and were favourable to consider it in any future website development they may be involved in. The outcome of the study shows that the use of accessible Web Content Management System with example-based accessibility awareness sessions can lead to improved accessibility outcomes for novice web content authors. This research strongly suggests that even small, focussed and example-based training/awareness raising session can drive an accessibility mindset in web content authors, even those with limited or no technical, accessibility or web authoring experience

From diversity to convergence : British computer networks and the Internet, 1970-1995

The Internet's success in the 21st century has encouraged analysts to investigate the origin of this network. Much of this literature adopts a teleological approach. Works often begin by discussing the invention of packet switching, describe the design and development of the ARPANET, and then examine how this network evolved into the Internet. Although the ARPANET was a seminal computer network, these accounts usually only briefly consider the many other diverse networks that existed. In addition, apart from momentary asides to alternative internetworking solutions, such as the Open Systems Interconnection (OSI) seven-layer reference model, this literature concentrates exclusively on the ARPANET, the Internet, and the World Wide Web. While focusing on these subjects is important and therefore justified, it can leave the reader with the impression that the world of networking started with the ARPANET and ended with the Internet. This thesis is an attempt to help correct this misconception. This thesis analyses the evolution of British computer networks and the Internet between the years 1970 and 1995. After an introduction in Chapter 1, the thesis analyses several networks. In Chapters 2 and 3, the focus is on academic networks, especially JANET and SuperJANET. Attention moves to videotex networks in Chapter 4, specifically Prestel, and in Chapter 5, the dissertation examines electronic mail networks such as Telecom Gold and Cable & Wireless Easylink. Chapter 6 considers online services, including CompuServe, American Online, and the Microsoft Network, and the thesis ends with a conclusion in Chapter 7. All of the networks discussed used protocols that were incompatible with each other which limited the utility of the networks for their users. Although it was possible that OSI or another solution could have solved this problem, the Internet's protocols achieved this objective. This thesis shows how the networks converged around TCP/IP

Tangible interfaces for manipulating aggregates of digital information

Thesis (Ph. D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2002.Includes bibliographical references (p. 255-269).This thesis develops new approaches for people to physically represent and interact with aggregates of digital information. These support the concept of Tangible User Interfaces (TUIs), a genre of human-computer interaction that uses spatially reconfigurable physical objects as representations and controls for digital information. The thesis supports the manipulation of information aggregates through systems of physical tokens and constraints. In these interfaces, physical tokens act as containers and parameters for referencing digital information elements and aggregates. Physical constraints are then used to map structured compositions of tokens onto a variety of computational interpretations. This approach is supported through the design and implementation of several systems. The mediaBlocks system enables people to use physical blocks to "copy and paste" digital media between specialized devices and general-purpose computers, and to physically compose and edit this content (e.g., to build multimedia presentations). This system also contributes new tangible interface techniques for binding, aggregating, and disaggregating sequences of digital information into physical objects.(cont.) Tangible query interfaces allow people to physically express and manipulate database queries. This system demonstrates ways in which tangible interfaces can manipulate larger aggregates of information. One of these query approaches has been evaluated in a user study, which has compared favorably with a best-practice graphical interface alternative. These projects are used to support the claim that physically constrained tokens can provide an effective approach for interacting with aggregates of digital information.by Brygg Anders Ullmer.Ph.D
