Online v. print reading: which one makes us smarter? : Scientific American Blog - 0 views

  • The process involves so much physical manipulation of the computer that it interferes with our ability to focus on and appreciate what we're reading
  • multimedia features, such as links to videos and animations, leave little room for imagination, limiting our ability to form our own mental pictures to illustrate what we're reading.
  • The visual happenings on the screen… and your physical interaction with the device is distracting," Mangen says. "All of these things are taxing on cognition and concentration in a way that a book is not."

  • implications of digital technology should be considered when deciding whether to incorporate computer teaching tools into classroom instruction.
  • many older people may absorb more or learn faster by flipping through pages, because their brains have been trained to read hard copy, whereas younger readers may learn faster digitally, because they're accustomed to working online

    Anne Mangen heittää teorian, että tietokoneen käsittely tuottaa kognitiivista kuormaa ja siten voi haitata oppimista. Uutisessa on lainattu myös muiden tutkijoiden eriäviä mielipiteitä. Joka tapauksessa kannattaa miettiä, missä tilanteissa tietokoneen käyttö on perusteltua ja milloin pitäisi voida keskittyä materiaalin sisäistämiseen ilman häiriötekijöitä.

Laptops in lectures | Tony Bates - 0 views

  • f most students have laptops, why are they still having physically to come to a lecture hall? Why can’t they get a podcast of the lecture? Second, if they are coming, why are the lecturers not requiring them to use their laptops for study?
  • So, yes, there are occasions when lectures work very well. But they should not be the default model for regular teaching in higher education. There are much better ways to teach that will result in better learning over the length of a course or program.

Jim Klein :: Weblog :: Netbooks and Open Source: Rethinking Laptops and Learning - 1 views

  • Netbooks are essentially mini-laptops that combine the physical characteristics of a cell phone with the capabilities of a traditional laptop, overcoming nearly all of the hardware obstacles to continuous student technology use in the classroom.
  • But hardware is only half of the picture. Open-source software is the answer to achieving cell phone reliability and ease of use on a device. With Linux and open-source software on netbooks, all the complexities of typical proprietary operating systems can be stripped away, leaving elegant, cell-phone like interfaces of simple icons, with reliable and secure underpinnings that are not prone to failure, malware, or general instability.
  • Through the use of free, open-source applications, students gain access to a diverse set of tools and resources for content creation, and teachers are empowered to challenge students to demonstrate subject area mastery using any one of a variety of tools and contexts. Since the software is free to distribute, students can install the same programs on any computer they have access to, creating an environment in which teachers can have a reasonable expectation that technology-based activities and assignments can be completed regardless of the student's location. And free classroom management tools enable teachers to monitor student activity, communicate privately or with groups, take control of a workstation, start a demonstration from theirs or any student's machine, and garner the attention of the class at a moment's notice, all through an easy to use interface on the teacher's workstation.

  • Absolutely yes, we've seen tremendous success in our district through the SUSD SWATTEC program. We've done nearly zero training on the laptops themselves, yet students are using them for amazing things on a daily basis, and teachers have embraced them to the degree that they are regularly used all day, every day in the learning environment. Is it replicable? Absolutely. All the software and every detail is available in true open-source fashion on the SUSD SWATTEC web site. Six school districts in four states (that we know of) are doing it now, with great success.

The Ed Techie: Using learning environments as a metaphor for educational change - 0 views

  • In examining the current physical space Wesch (2008) asked students what a lecture hall ‘said’ about learning, in essence what were the affordances (Gibson 1979; Norman 1988) of the standard learning environment. They listed the following: To learn is to acquire information Information is scare and hard to find Trust authority for good information Authorized information is beyond discussion Obey the authority Follow along
  • These are obviously at odds with what most educators regard as key components in learning, such as dialogue, reflection, critical analysis, etc. They are also at distinct odds with the type of experience students have in the online world they inhabit regularly, particularly the social network, read/write web. These environments are characterised by User-generated content Power of the crowd Data on an epic scale Architecture of participation Network effects Openness

  • When it was necessary for education to be performed face to face, a number of services were bundled together. When it becomes digital and online, this may no longer be the case, as we have seen in most content industries, such as music and newspapers (education has some similarities with content and also some significant differences). The first round of learning tools replicated the centralised model, but as the tools have become easier to use, and the methods for integrating them simpler, so this centralised approach seems less applicable. Clay Shirky (2008) argues that the ‘cost’ of organising people has collapsed, which makes informal groupings more likely to occur and often more successful:"By making it easier for groups to self-assemble and for individuals to contribute to group effort without requiring formal management, these tools have radically altered the old limits on the size, sophistication, and scope of unsupervised effort"Part of the function of universities is to provide this organisation, for example by grouping individuals together to form a student cohort who are interested in the same subject. But as this grouping becomes easier to do online, it becomes less of a valued function of the university - ie you don’t need to go to a university to find like minded people. Education then faces the same challenges regarding the cost of organisation that, say, the Encyclopedia Brittanica faced from wikipedia. Returning to the theme of this paper, Shirky’s argument can also be applied to technology, namely that the ‘cost’ of integrating technology has drastically reduced, meaning it is now feasible for individuals to do this, thus alleviating the need for centrally provided pre-integrated solutions. For example, we could reword the above quote to read:By making it easier for tools to (self) assemble and for applications to contribute to the environment without requiring integration, these approaches have radically altered the old limits on the size, sophistication, and scope of any individual to create their own environmentProjects such as SocialLearn, illustrate that the conceptualisation of a learning environment goes beyond technical, or even pedagogical considerations. In a digital society it comes to represent the institutional response to changes in the nature of knowledge creation, sharing, and participation, in short to the nature of education itself. Shirky argues that ‘when we change the way we communicate, we change society’, and the new socially based technologies we have today are doing this in fundamental ways. It is only by exploring their potential that universities can remain relevant to the society they are helping to shape.

    The central theme of this article is that the online learning environment can be seen as the means by which higher education can explores the challenges and opportunities raised by online and digital society.
