Computing as the 4th “R”: a general education approach to computing education

Computing and computation are increasingly pervading our lives, careers, and societies - a change driving interest in computing education at the secondary level. But what should define a "general education" computing course at this level? That is, what would you want every person to know, assuming they never take another computing course? We identify possible outcomes for such a course through the experience of designing and implementing a general education university course utilizing best-practice pedagogies. Though we nominally taught programming, the design of the course led students to report gaining core, transferable skills and the confidence to employ them in their future. We discuss how various aspects of the course likely contributed to these gains. Finally, we encourage the community to embrace the challenge of teaching general education computing in contrast to and in conjunction with existing curricula designed primarily to interest students in the field

Introducing TU100 ‘My Digital Life’: Ubiquitous computing in a distance learning environment

In this paper we describe the Open University’s progress towards delivering an introduction to ubiquitous computing within a distance-learning environment. Our work is strongly influenced by the philosophy of learning-through-play and we have taken technologies originally designed for children’s education and adapted them for adult learners, many of whom will have no formal experience of computer science or information technology. We will introduce two novel technologies; Sense, a drag-and-drop programming language based on Scratch; and the SenseBoard, an inexpensive hardware device that can be connected to the student’s computer, through which they can sense their environment and display outputs. This paper is not intended as a detailed discussion of individual technologies (they will follow in time), rather it should serve as an introduction to the Open University’s method of teaching and how we hope to continue to recruit new computer scientists and engineers using novel technologies

Mobility is the Message: Experiments with Mobile Media Sharing

This thesis explores new mobile media sharing applications by building, deploying, and studying their use. While we share media in many different ways both on the web and on mobile phones, there are few ways of sharing media with people physically near us. Studied were three designed and built systems: Push!Music, Columbus, and Portrait Catalog, as well as a fourth commercially available system – Foursquare. This thesis offers four contributions: First, it explores the design space of co-present media sharing of four test systems. Second, through user studies of these systems it reports on how these come to be used. Third, it explores new ways of conducting trials as the technical mobile landscape has changed. Last, we look at how the technical solutions demonstrate different lines of thinking from how similar solutions might look today. Through a Human-Computer Interaction methodology of design, build, and study, we look at systems through the eyes of embodied interaction and examine how the systems come to be in use. Using Goffman’s understanding of social order, we see how these mobile media sharing systems allow people to actively present themselves through these media. In turn, using McLuhan’s way of understanding media, we reflect on how these new systems enable a new type of medium distinct from the web centric media, and how this relates directly to mobility. While media sharing is something that takes place everywhere in western society, it is still tied to the way media is shared through computers. Although often mobile, they do not consider the mobile settings. The systems in this thesis treat mobility as an opportunity for design. It is still left to see how this mobile media sharing will come to present itself in people’s everyday life, and when it does, how we will come to understand it and how it will transform society as a medium distinct from those before. This thesis gives a glimpse at what this future will look like

Always in control? Sovereign states in cyberspace

For well over twenty years, we have witnessed an intriguing debate about the nature of cyberspace. Used for everything from communication to commerce, it has transformed the way individuals and societies live. But how has it impacted the sovereignty of states? An initial wave of scholars argued that it had dramatically diminished centralised control by states, helped by a tidal wave of globalisation and freedom. These libertarian claims were considerable. More recently, a new wave of writing has argued that states have begun to recover control in cyberspace, focusing on either the police work of authoritarian regimes or the revelations of Edward Snowden. Both claims were wide of the mark. By contrast, this article argues that we have often misunderstood the materiality of cyberspace and its consequences for control. It not only challenges the libertarian narrative of freedom, it suggests that the anarchic imaginary of the Internet as a ‘Wild West’ was deliberately promoted by states in order to distract from the reality. The Internet, like previous forms of electronic connectivity, consists mostly of a physical infrastructure located in specific geographies and jurisdictions. Rather than circumscribing sovereignty, it has offered centralised authority new ways of conducting statecraft. Indeed, the Internet, high-speed computing, and voice recognition were all the result of security research by a single information hegemon and therefore it has always been in control

Developing computational thinking in the classroom: a framework

Computational thinking sits at the heart of the new statutory programme of study for Computing: “A high quality computing education equips pupils to use computational thinking and creativity to understand and change the world” (Department for Education, 2013, p. 188). This document aims to support teachers to teach computational thinking. It describes a framework that helps explain what computational thinking is, describes pedagogic approaches for teaching it and gives ways to assess it. Pupil progression with the previous ICT curriculum was often demonstrated through ‘how’ (for example, a software usage skill) or ‘what’ the pupil produced (for example, a poster). This was partly due to the needs of the business world for office skills. Such use of precious curriculum time however has several weaknesses. Firstly, the country’s economy depends on technological innovation not just on use of technology. Secondly, the pace of technology and organisational change is fast in that the ICT skills learnt are out of date before a pupil leaves school. Thirdly, technology invades all aspects of our life and the typically taught office practice is only a small part of technology use today
