  • the incorporation of Information and Communication Technologies into Primary Education brought with it positive changes in the role of the teacher and the student. Teachers and students stopped being mere transmitters and receptors, respectively. The first became mediators of information and the second opted for learning through investigating, discovering and presenting ideas to classmates and teachers. In this way they have, at the same time, the opportunity of getting to know the work of other students, too. Thus, the use of Internet and ICTs reinforce participation and collaboration in the school. According to Dr Altuna, it also helps to boost learning models that are more constructivist, socio-constructivist and even connectivist.
  • Despite its educational possibilities the researcher warns that there are numerous factors that limit the incorporation of Internet into the teaching of the curricular subject in question. These involve aspects such as the time dedicated weekly, technological and computer facilities, accessibility and connection to Internet, the school curriculum and, above all, the knowledge, training and involvement of the teaching staff.
  • the thesis observed a tendency to delegate responsibility for ICT in the school to those teachers who were considered to be “computer experts”. Dr Altuna warns of the risks that this practice runs, as thereby the rest of the staff continues to be untrained and unable to apply ICT and Internet in activities undertaken within their curricular subject. It has to be stressed, therefore, that all should be responsible for the educational measures to be taken so that students acquire digital skills. Also observed was the need for a pedagogic approach to ICT which advises the teaching staff on knowledge about and putting into practice activities in educational innovation.

  • Dr Altuna not only includes the lack of involvement of teaching staff amongst the limitations for incorporating ICT, but also that of the involvement of the families. It was explained that families showed interest in the use of Internet and ICTs as educational tools for their children, but that these, too, excessively delegate to the schools. The researcher stressed that the families also need guidance, as they are concerned about the use by their children of Internet but do not know the best way to go about the problem.
  • Educational psychologist Dr Jon Altuna has carried out a thorough study of the phenomenon of the school 2.0. Concretely, he has looked into the use and level of incorporation of Internet and of Information and Communication Technologies (ICT) into the third cycle of Primary Education, observing at the same time the attitudes of the teaching staff, and of the students and the families of the children in this regard. His PhD, defended at the University of the Basque Country (UPV/EHU), is entitled, Incorporation of Internet into the teaching of the subject Knowledge of the Environment during the third cycle of Primary Education: possibilities and analysis of the situation of a school. Dr Altuna’s research is based on a study of cases undertaken over eight years at a school where new activities involving ICT had been introduced into the curricular subject of Knowledge of the Environment, taught in the fifth and sixth year of Primary Education. The researcher gathered data from 837 students, 134 teachers and 190 families of this school. This study was completed with the experiences of ICT teachers from 21 schools.

Cancer Evolution Life

  • astrobiologists, working with oncologists in the US, have suggested that cancer resembles ancient forms of life that flourished between 600 million and 1 billion years ago.
  • Read more about what this discovery means for cancer research.
  • The genes that controlled the behaviour of these early multicellular organisms still reside within our own cells, managed by more recent genes that keep them in check.It's when these newer controlling genes fail that the older mechanisms take over, and the cell reverts to its earlier behaviours and grows out of control.

  • The new theory, published in the journal Physical Biology, has been put forward by two leading figures in the world of cosmology and astrobiology: Paul Davies, director of the Beyond Center for Fundamental Concepts in Science, Arizona State University; and Charles Lineweaver, from the Australian National University.
  • According to Lineweaver, this suggests that cancer is an atavism, or an evolutionary throwback.
  • In the paper, they suggest that a close look at cancer shows similarities with early forms of multicellular life.
  • “Unlike bacteria and viruses, cancer has not developed the capacity to evolve into new forms. In fact, cancer is better understood as the reversion of cells to the way they behaved a little over one billion years ago, when humans were nothing more than loose-knit colonies of only partially differentiated cells. “We think that the tumours that develop in cancer patients today take the same form as these simple cellular structures did more than a billion years ago,” he said.
  • One piece of evidence to support this theory is that cancers appear in virtually all metazoans, with the notable exception of the bizarre naked mole rat."This quasi-ubiquity suggests that the mechanisms of cancer are deep-rooted in evolutionary history, a conjecture that receives support from both paleontology and genetics," they write.
  • the genes that controlled this early multi-cellular form of life are like a computer operating system's 'safe mode', and when there are failures or mutations in the more recent genes that manage the way cells specialise and interact to form the complex life of today, then the earlier level of programming takes over.
  • Their notion is in contrast to a prevailing theory that cancer cells are 'rogue' cells that evolve rapidly within the body, overcoming the normal slew of cellular defences.
  • However, Davies and Lineweaver point out that cancer cells are highly cooperative with each other, if competing with the host's cells. This suggests a pre-existing complexity that is reminiscent of early multicellular life.
  • cancers' manifold survival mechanisms are predictable, and unlikely to emerge spontaneously through evolution within each individual in such a consistent way.
  • The good news is that this means combating cancer is not necessarily as complex as if the cancers were rogue cells evolving new and novel defence mechanisms within the body.Instead, because cancers fall back on the same evolved mechanisms that were used by early life, we can expect them to remain predictable, thus if they're susceptible to treatment, it's unlikely they'll evolve new ways to get around it.
  • If the atavism hypothesis is correct, there are new reasons for optimism," they write.

Community Informatics and Older Persons: The Necessary Connection « Gurstein'... - 0 views

Age Community Informatics ICT

shared by Weiye Loh on 07 Mar 12 - No Cached
  • we know instinctively and research evidence itself is beginning to emerge that particularly in the case of older persons individualized, medicalized, institutionally focused care may be precisely what is not needed and may have the effect over the span of the final decades of life to not only reduce the quality of life but even the length of life itself.
  • individuals including or even especially older persons are happiest and healthiest and thus less likely to need interventions from the formal medical system if they are living surrounded by family and friends and firmly embedded in communities where they have support, friendship and love.

Internet Economics Accounting Statistics Measurement

shared by Weiye Loh on 26 Sep 11 - No Cached
  • it appears that there is a quite significant hole in the National Accounting (and thus the GDP statistics) around Internet related activities since most of this accounting is concerned with measuring the production and distribution of tangible products and the associated services. For the most part the available numbers don’t include many Internet (or “social capital” e.g. in health and education) related activities as they are linked to intangible outputs. The significance of not including social capital components in the GDP has been widely discussed elsewhere. The significance (and potential remediation) of the absence of much of the Internet related activities was the subject of the workshop.
  • there had been a series of critiques of GDP statistics from Civil Society (CS) over the last few years—each associated with a CS “movements—the Woman’s Movement and the absence of measurement of “women’s (and particularly domestic) work”; the Environmental Movement and the absence of the longer term and environmental costs of the production of the goods that the GDP so blithely counts as a measure of national economic well-being; and most recently with the Sustainability Movement, and the absence of measures reflective of the longer term negative effects/costs of resource depletion and environmental degradation. What I didn’t see anywhere apart from the background discussions to the OECD workshop itself were critiques reflecting issues related to the Internet or ICTs.
  • the implications of the limitations in the Internet accounting went beyond a simple technical glitch and had potentially quite profound implications from a national policy and particularly a CS and community based development perspective. The possible distortions in economic measurement arising from the absence of Internet associated numbers in the SNA (there may be some $750 BILLION a year in “value’ being generated by Internet based search alone!) lead to the very real possibility that macro-economic analysis and related policy making may be operating on the basis of inadequate and even fallacious assumptions.

  • perhaps of greatest significance from the perspective of Civil Society and of communities is the overall absence of measurement and thus inclusion in the economic accounting of the value of the contributions provided to, through and on the Internet of various voluntary and not-for-profit initiatives and activities. Thus for example, the millions of hours of labour contributed to Wikipedia, or to the development of Free or Open Source software, or to providing support for public Internet access and training is not included as a net contribution or benefit to the economy (as measured through the GDP). Rather, this is measured as a negative effect since, as some would argue, those who are making this contribution could be using their time and talents in more “productive” (and “economically measurable”) activities. Thus for example, a region or country that chooses to go with free or open source software as the basis for its in-school computing is not only “not contributing to ‘economic well being’” it is “statistically” a “cost” to the economy since it is not allowing for expenditures on, for example, suites of Microsoft products.
  • there appears to have been no systematic attention paid to the relationship of the activities and growth of voluntary contributions to the Internet and the volume, range and depth of Internet activity, digital literacy and economic value being derived from the use of the Internet.

Technology Education ICT

shared by Weiye Loh on 04 Sep 11 - No Cached
  • In the United States, nearly a half century of research, application of new technologies and development of new methods and policies has failed to translate into improved reading abilities for the nation’s children1.
  • the reasons why progress has been so uneven point to three simple rules for anticipating when more research and development (R&D) could help to yield rapid social progress. In a world of limited resources, the trick is distinguishing problems amenable to technological fixes from those that are not. Our rules provide guidance\ in making this distinction . . .
  • unlike vaccines, the textbooks and software used in education do not embody the essence of what needs to be done. That is, they don’t provide the basic ‘go’ of teaching and learning. That depends on the skills of teachers and on the attributes of classrooms and students. Most importantly, the effectiveness of a vaccine is largely independent of who gives or receives it, and of the setting in which it is given.

  • The three rules for a technological fix proposed by Sarewitz and Nelson are: I. The technology must largely embody the cause–effect relationship connecting problem to solution. II. The effects of the technological fix must be assessable using relatively unambiguous or uncontroversial criteria. III. Research and development is most likely to contribute decisively to solving a social problem when it focuses on improving a standardized technical core that already exists.
  • technology in the classroom fails with respect to each of the three criteria: (a) technology is not a causal factor in learning in the sense that more technology means more learning, (b) assessment of educational outcome sis itself difficult and contested, much less disentangling various causal factors, and (c) the lack of evidence that technology leads to improved educational outcomes means that there is no such standardized technological core.
  • This conundrum calls into question one of the most significant contemporary educational movements. Advocates for giving schools a major technological upgrade — which include powerful educators, Silicon Valley titans and White House appointees — say digital devices let students learn at their own pace, teach skills needed in a modern economy and hold the attention of a generation weaned on gadgets. Some backers of this idea say standardized tests, the most widely used measure of student performance, don’t capture the breadth of skills that computers can help develop. But they also concede that for now there is no better way to gauge the educational value of expensive technology investments.
  • absent clear proof, schools are being motivated by a blind faith in technology and an overemphasis on digital skills — like using PowerPoint and multimedia tools — at the expense of math, reading and writing fundamentals. They say the technology advocates have it backward when they press to upgrade first and ask questions later.
  • [D]emand for educated labour is being reconfigured by technology, in much the same way that the demand for agricultural labour was reconfigured in the 19th century and that for factory labour in the 20th. Computers can not only perform repetitive mental tasks much faster than human beings. They can also empower amateurs to do what professionals once did: why hire a flesh-and-blood accountant to complete your tax return when Turbotax (a software package) will do the job at a fraction of the cost? And the variety of jobs that computers can do is multiplying as programmers teach them to deal with tone and linguistic ambiguity. Several economists, including Paul Krugman, have begun to argue that post-industrial societies will be characterised not by a relentless rise in demand for the educated but by a great “hollowing out”, as mid-level jobs are destroyed by smart machines and high-level job growth slows. David Autor, of the Massachusetts Institute of Technology (MIT), points out that the main effect of automation in the computer era is not that it destroys blue-collar jobs but that it destroys any job that can be reduced to a routine. Alan Blinder, of Princeton University, argues that the jobs graduates have traditionally performed are if anything more “offshorable” than low-wage ones. A plumber or lorry-driver’s job cannot be outsourced to India.

    In 2008 Dick Nelson and Dan Sarewitz had a commentary in Nature (here in PDF) that eloquently summarized why it is that we should not expect technology in the classroom to reault in better educational outcomes as they suggest we should in the case of a tehcnology like vaccines
