The social construction of educational technology through the use of proprietary software
Major strands of science and technology studies (STS) in recent decades have been the 'social shaping of technology' (SST) and 'social construction of technology' (SCOT) movements, whose adherents maintain that technological systems are determined just as much by social forces as by technological ones. Taking this 'co-construction' notion as a starting point, and putting a focus on the user, I look at some examples of the use of proprietary software in which the learner, instead of being constrained by a rather deterministic pedagogy of educational technology, can exploit the functionality of the software in ways far removed from the original design. For example, spreadsheets can be used to incorporate modelling assumptions directly to simulate digital signal transmission, or the workings of the binomial function. Audio editing software can be used to teach about the technology of music by allowing the student to explore waveform characteristics. The manipulation of images, if combined with a teaching of the principles behind data compression, can engender a deep understanding of the processes involved. And translation software can be used for language learning in a way very different from what was envisaged by the designers. Educational technology has tended to suffer from an emphasis on, and excessive claims for, technological innovation and novelty. Film, radio, television, programmed learning, interactive video discs, CD-ROMs, a 'computer in every classroom', 'one laptop per child', the web, computer-mediated communication, smartboards; and now mashups, Second Life, Facebook, YouTube and Twitter – all have all been seen as radical new technologies that would revolutionize learning. Here I make the case for the social construction of educational technology by users and teachers, based on exploiting to far better effect the possibilities of mature, often proprietary, software not originally designed for pedagogical purposes. The approach outlined here not only helps students gain experience with the sort of software they are likely to encounter in their professional life, but also fosters and sustains a healthy spirit of enquiry that too often is lacking in much educational software. Although the examples presented have been situated in the context of the individual learner, similar principles can be applied to a whole range of networked educational technologies
Using pattern languages to mediate theory–praxis conversations in design for networked learning
Educational design for networked learning is becoming more complex but also more inclusive, with teachers and learners playing more active roles in the design of tasks and of the learning environment. This paper connects emerging research on the use of design patterns and pattern languages with a conception of educational design as a conversation between theory and praxis. We illustrate the argument by drawing on recent empirical research and literature reviews from the field of networked learning

Students, the Net Generation and Digital Natives:Accounting for Educational Change
This chapter examines a number of different terms and popularized accounts of young people who are now at the stage in their lives of engaging in university education across the world. Three of the more common terms that have been used to describe this cohort of young people are the Net generation (Tapscott 1998, 2009), Digital Natives (Prensky 2001; 2001a: 2009) and Millennials (Howe and Strauss 2000; Oblinger & Oblinger 2005).
This chapter critically examines the argument, common to writers using both terms: that the existence of an environment infused with digital and networked technologies, combined with an active engagement in these new technologies, leads directly to a sharp generational break. The chapter goes on to examine the determinist nature of the argument and the way this has been related to one particular pedagogical approach; collaborative learning. It examines the wider social and technological context and in particular the ideas of networked individualism and networked sociality. Finally the chapter concludes by examining which aspects of the Digital Native and Net Generation arguments are worth taking forward and by identifying those aspects of the arguments that need to be abandoned

The net generation and digital natives: implications for higher education
Executive Summary
"Our students have changed radically. Today�s students are no longer the people our educational system was designed to teach." (Prensky 2001 p1)
1. There is no evidence that there is a single new generation of young students entering Higher Education and the terms Net Generation and Digital Native do not capture the processes of change that are taking place.
2. The complex changes that are taking place in the student body have an age related component that is most obvious with the newest waves of technology. Prominent amongst these are the uses made of social networking sites (e.g. Facebook), uploading and manipulation of multimedia (e.g. YouTube) and the use of handheld devices to access the mobile Internet.
3. Demographic factors interact with age to pattern students� responses to new technologies. The most important of these are gender, mode of study (distance or place-based) and the international or home status of the student.
4. The gap between students and their teachers is not fixed, nor is the gulf so large that it cannot be bridged. In many ways the relationship is determined by the requirements teachers place upon their students to make use of new technologies and the way teachers integrate new technologies in their courses. There is little evidence that students enter university with demands for new technologies that teachers and universities cannot meet.
5. Students persistently report that they prefer moderate use of Information and Communication Technologies (ICT) in their courses. Care should be taken with this finding because the interpretation of what is �moderate� use of ICT may be changing as a range of new technologies take off and become embedded in social life and universities.
6. Universities should be confident in the provision of what might seem to be basic services. Students appreciate and make use of the foundational infrastructure for learning, even where this is often criticised as being an out of date and unimaginative use of new technology. Virtual Learning Environments (Learning or Course Management Systems) are used widely and seem to be well regarded. The provision by university libraries of online services, including the provision of online e-journals and e-books, are also positively received.
7. Students do not naturally make extensive use of many of the most discussed new technologies such as Blogs, Wikis and 3D Virtual Worlds. The use of 3D Virtual Worlds is notably low amongst students. The use of Wikis and Blogs is relatively low overall, but use does vary between different contexts, including national and regional contexts. Students who are required to use these technologies in their courses are unlikely to reject them and low use does not imply that they are inappropriate for educational use. The key point being made is that there is not a natural demand amongst students that teaching staff and universities should feel obliged to satisfy.
8. There is no obvious or consistent demand from students for changes to pedagogy at university (e.g. demands for team and group working). There may be good reasons why teachers and universities wish to revise their approaches to teaching and learning, or may wish to introduce new ways of working. Students will respond positively to changes in teaching and learning strategies that are well conceived, well explained and properly embedded in courses and degree programmes. However there is no evidence of a pent-up demand amongst students for changes in pedagogy or of a demand for greater collaboration.
9. There is no evidence of a consistent demand from students for the provision of highly individualised or personal university services. The development of university infrastructures, such as new kinds of learning environments (for example Personal Learning Environments) should be choices about the kinds of provision that the university wishes to make and not a response to general statements about what a new generation of students are demanding.
10. Advice derived from generational arguments should not be used by government and government agencies to promote changes in university structure designed to accommodate a Net Generation of Digital Natives. The evidence indicates that young students do not form a generational cohort and they do not express consistent or generationally organised demands. A key finding of this review is that political choices should be made explicit and not disguised by arguments about generational change
Who you’re gonna call? The development of university digital leaders
In our hyper-connected digitised educational world, university tutors are interested in capitalising on affordances of digital trends in teaching and learning. Students, under the alias of preservice- teachers, walk among them equipped with digital skills in areas of their interest. How can we encourage collaboration between tutors and students that can promote the use of the digital force wisely, support the development of students’ professional identities further and extend tutors’ digital competences? The story of nine tutors and eleven undergraduate pre-service-teachers working together on digital partnerships is set against discussions around digital leadership and citizenship. This case study aims to highlight how universities can respond to technology-driven change by engaging students further and support their awareness of digital citizenship. The overall results showed that the informal learning that students have capitalised outside the classroom can be used to scaffold their development of digital citizenship through offline community engagement. It demonstrates the advantage of using such opportunities as a means to encourage citizenship practices among university student communities and the positive impact that such synergies can have on all the participants

Harmony and Technology Enhanced Learning
New technologies offer rich opportunities to support education in harmony. In this chapter we consider theoretical perspectives and underlying principles behind technologies for learning and teaching harmony. Such perspectives help in matching existing and future technologies to educational purposes, and to inspire the creative re-appropriation of technologies
Characterizing Service Level Objectives for Cloud Services: Motivation of Short-Term Cache Allocation Performance Modeling
Service level objectives (SLOs) stipulate performance goals for cloud applications, microservices, and infrastructure. SLOs are widely used, in part, because system managers can tailor goals to their products, companies, and workloads. Systems research intended to support strong SLOs should target realistic performance goals used by system managers in the field. Evaluations conducted with uncommon SLO goals may not translate to real systems. Some textbooks discuss the structure of SLOs but (1) they only sketch SLO goals and (2) they use outdated examples. We mined real SLOs published on the web, extracted their goals and characterized them. Many web documents discuss SLOs loosely but few provide details and reflect real settings. Systematic literature review (SLR) prunes results and reduces bias by (1) modeling expected SLO structure and (2) detecting and removing outliers. We collected 75 SLOs where response time, query percentile and reporting period were specified. We used these SLOs to confirm and refute common perceptions. For example, we found few SLOs with response time guarantees below 10 ms for 90% or more queries. This reality bolsters perceptions that single digit SLOs face fundamental research challenges.This work was funded by NSF Grants 1749501 and 1350941.No embargoAcademic Major: Computer Science and EngineeringAcademic Major: Financ
