Ahimsa: Sita Sings the Blues now CC-0 “Public Domain” « Nina Paley’s Blog

Ahimsa: Sita Sings the Blues now CC-0 “Public Domain” « Nina Paley’s Blog | OER Resources: open ebooks & OER resources for open educations & research | Scoop.it

A few years ago I started thinking about taking a vow of non-violence: a commitment to never sue anyone over Knowledge (or Culture, Cultural Works, Art, Intellectual Pooperty, whatever you call it). Copyright law is hopelessly broken; indeed, the Law in the US is broken all over the place. Why would I resort to the same broken law to try to fix abuses that occur within it?

We live in a messed-up world. My choices, however principled, will not change that. People will continue to censor, suppress, and enclose Knowledge. Share-Alike – the legal requirement to keep Knowledge Free – has ironically resulted in the suppression of same.

Not using knowledge is an offense to it,” wrote Jeff Jarvis, reflecting on the death of Aaron Swartz.

I learned of Aaron’s death on Sunday; on Monday, the National Film Board of Canada told me I had to fill out paperwork to “allow” filmmaker (and personal friend) Chris Landreth to refer to Sita Sings the Blues in his upcoming short, Subconscious Password, even though Fair Use already freed the NFB from any legitimate fear of Share-Alike’s viral properties. I make compromises to my principles every day, but that Monday I just couldn’t. The idiocy of NFB’s lawyers was part of the same idiocy that Aaron fought in liberating documents from JSTOR. I couldn’t bear to enable more bad lawyers, more bad decisions, more copyright bullshit, by doing unpaid paperwork for a corrupt and stupid system. I just couldn’t.

....

Phil Parker is unlike any writer you've ever met - or read for that matter. That's because he doesn't write most of his books. Instead, the trained economist uses sophisticated algorithms that can pen a whole book from start to finish in as little as a few minutes. The secret is sophisticated programming mimicking the thought process behind formulaic writing. It can take years to create these programs, but once completed, new books can be churned out in minutes.

Reaching out with OER: the new role of public-facing open scholar - Open Research Online

Reaching out with OER: the new role of public-facing open scholar - Open Research Online | OER Resources: open ebooks & OER resources for open educations & research | Scoop.it

Open educational resources (OER) and, more recently, open educational practices (OEP) have been widely promoted as a means of increasing openness in higher education (HE). Thus far, such openness has been limited by OER provision typically being supplier-driven and contained within the boundaries of HE. Seeking to explore ways in which OEP might become more needs-led we conceptualised a new ‘public-facing open scholar’ role involving academics working with online communities to source and develop OER to meet their needs.

To explore the scope for this role we focused on the voluntary sector, which we felt might particularly benefit from such collaboration. We evaluated four representative communities for evidence of their being self-educating (thereby offering the potential for academics to contribute) and for any existing learning dimension. We found that all four communities were self-educating and each included learning infrastructure elements, for example provision for web chats with ‘experts’, together with evidence of receptiveness to academic collaboration. This indicated that there was scope for the role of public-facing open scholar. We therefore developed detailed guidelines for performing the role, which has the potential to be applied beyond the voluntary sector and to greatly extend the beneficial impact of existing OER, prompting institutions to release new OER in response to the needs of people outside HE.

Reuse, not production, is key to positive MOOC impact | Keep Learning

Reuse, not production, is key to positive MOOC impact | Keep Learning | OER Resources: open ebooks & OER resources for open educations & research | Scoop.it
The issue in higher education is that the really hard and important problems — the problems that no one has solved yet, the problems that will ultimately destroy us — are problems of reuse, not production. David Wiley nailed this years ago in his reusability paradox. Briefly stated, the paradox is this –
..

Designing for reuse (in most situations) means removing contextually-dependent hooks from designed objects.
The value proposition of higher education, unfortunately, is largely the process of contextualization of knowledge. What students find useful in a course is the coherence-building that a teacher and other students provide. Small contextually-dependent hooks such as “As we mentioned last week” are the bread-and-butter sense-making of any course.
Therefore “pedagogical effectiveness and potential for reuse are completely at odds with one another.”
To some extent calling out this paradox was a plea for a truly open set of educational resources – not PDFs of slides, but actual editable PowerPoints. Not DRM’d learning objects, but cuttable videos. Not textbooks as ePubs, but textbooks as editable documents. To be open is to permit local re-contextualization.

ghbrett's curator insight, December 19, 2012 8:57 AM

Re-use, or re-purposing has been valued by innovative teachers and trainers for years. I remember when MIT was developing the Athena networked learning modules. A friend of mine was a cinematographer for the project. Because they wanted to use the media across varied disciplines they actually ended up creating a hypermedia archive of and around Paris, France. This satisfied foreign languages, architecture, the arts, and other disciplines. One comment he made was the need for multiple beginnings that linked to varied middle content and had multiple endings. So, my take away relates to the notion of "contextual-dependent hooks" and "coherence building" as mentioned above. 

 

Action Item: When using or modifying Open Education Resources, MOOCs, or other Open Content in different situations (aka, Context) why not create or add a link to the new elements or scenarios in order to provide new users to better understand how they might adapt the content to their needs.

Instructors have a new free resource to help them integrate content from TED talks into their courses. TED has teamed up with publisher John Wiley & Sons to create PC- and iPad-based content that can be used to support lessons on happiness studies and statistics, with more on the way. TED is a non-profit organization that holds events drawing experts and presenters from multiple fields to share their work and thinking in a plethora of areas. Those "talks" are recorded and freely shared on the TED Web site.

TED Studies, as the new program is named, combines recorded TED video sessions on a given topic and adds essays and activities to round out each set of programs.

Creative Commons content is awesome, but attributing it properly can be difficult and confusing.
How-to guides and user education haven't helped much. We need a simple tool everyone can use to do the right thing with the click of a button.
That's why we're building OpenAttribute, a suite of tools that makes it ridiculously simple for anyone to copy and paste the correct attribution for any CC licensed work.
The tools include a simple add-on for web browsers, and plug-ins for popular publishing platforms like Flickr, Wordpress, MediaWiki and Drupal.
The result: OpenAttribute makes it easy for everyday people to use open and Creative Commons content. And ensures content attributiven get credit for their work.

What I learned from the notes and the silences left between them.

Where David Foster Wallace showed writers like me the possibilities of labyrinthine stories and digressions, Davis showed me how to be affecting without being opaque, lyrical without being verbose. Editing imbued each of Davis’s notes with more weight. It also let his melodic lines breathe, an effect that highlighted the depth and strength of his lyricism. No matter the tempo, Davis’s precise, deft touch produced solos whose moods ranged from buoyant to brooding, mournful to sweet.

In their submissions to the Australian Law Reform Commission’s review of copyright legislation, both Universities Australia and the University of Sydney argue the Copyright Act is holding back innovation in the tertiary education sector.

The sector is particularly concerned that current “fair dealing” provisions in the Copyright Act do not support the use of copyrighted material in the delivery of Massive Open Online Courses (MOOCs).

“The University supports copyright law reform that will foster new and innovative ways of providing education to a wider audience,” wrote University of Sydney Vice-Chancellor Dr Michael Spence in the university’s submission to the review.

“Of particular concern are the communication limits that restrict the ability to teach our students in a way that is fair in other jurisdictions,” Dr Spence wrote.

Pictured above is our top pick of artists and writers whose works will, on 1st January 2013, be entering the public domain in those countries with a ‘life plus 70 years’ copyright term (e.g. most European Union members, Brazil, Israel, Nigeria, Russia, Turkey, etc.). An eclectic bunch have assembled for our graduation photo – including the two founding fathers of anthropology from different sides of the Atlantic, an Army officer turned “premature hippy”, the painter of one of America’s most iconic images, and a canonised Catholic saint who studied with Martin Heidegger. The unifying factor bringing them all together is that all died in the year of 1942, many sadly as a result, directly or indirectly, of the Second World War.

What Could Have Entered the Public Domain on January 1, 2013?

What Could Have Entered the Public Domain on January 1, 2013? | OER Resources: open ebooks & OER resources for open educations & research | Scoop.it

Current US law extends copyright for 70 years after the date of the author’s death, and corporate “works-for-hire” are copyrighted for 95 years after publication. But prior to the 1976 Copyright Act (which became effective in 1978), the maximum copyright term was 56 years – an initial term of 28 years, renewable for another 28 years. Under those laws, works published in 1956 would enter the public domain on January 1, 2013, where they would be “free as the air to common use.” Under current copyright law, we’ll have to wait until 2052.1 And no published works will enter our public domain until 2019. (The law in the EU is different – thousands of works from authors who died in 1942 are entering their public domain on January 1.) Even more shockingly, the Supreme Court ruled in 2012 that Congress can take back works from the public domain. Could Shakespeare, Plato, or Mozart be pulled back into copyright? The Supreme Court gave no reason to think that they could not be.

Copyrighted History of the English-Speaking Peoples

What books would be entering the public domain if we had the pre-1978 copyright laws? You might recognize some of the titles below.

You would be free to translate these books into other languages, create Braille or audio versions for visually impaired readers (if you think that publishers wouldn’t object to this, you would be wrong), or adapt them for film. You could read them online or buy cheaper print editions, because others were free to republish them. (Empirical studies have shown that public domain books are less expensive, available in more editions, and more likely to be in print.) Imagine a digital Library of Alexandria containing all of the world’s books from 1956 and earlier, where, thanks to technology, you can search, link, index, annotate, copy and paste. Not so fast … instead of seeing these works enter the public domain in 2013, we will have to wait until 2052.


The same is true for some of the great periodicals from 1956. These include the first issue of MADmagazine with Alfred E. Neuman prominently featured on the cover, as well as the debut issues ofNew Scientist, teen magazines such as Walt Disney’s Mickey Mouse Club Magazine, and the short-lived science fiction magazines SatelliteScience Fiction Adventures, and Super Science Fiction.

The Best OER Revise / Remix Ever?

The Best OER Revise / Remix Ever? | OER Resources: open ebooks & OER resources for open educations & research | Scoop.it
In fall of 2011, I took a new approach to the Project Management course I teach each year. I wanted my students to gain hands on experience managing a project, I wanted them to feel the pressure of hitting deliverables, I wanted them to feel the nausea of having things fall through, I wanted them to learn to navigate managing people, and most of all I wanted them to feel the joy of completing a piece of work that blesses people lives. So I asked my students to engage in a very large scale revise / remix project that would benefit them and many others.

We started with Project Management from Simple to Complex, originally written by Russell Darnall and John Preston and originally published under a Creative Commons BY-NC-SA license by Flat World Knowledge. For the last two years now we’ve been revising and remixing away on Project Management for Instructional Designers (PM4ID). Here’s what we’ve done:

Aligned each chapter with the relevant portions of the Certified Associate in Project Management (CAPM) certification exam and the Project Manager Professional (PMP) certification exam, so that you can now use PM4ID to study for these exams,
Removed generic examples like ‘You have to get 13,000 tons of concrete to Singapore by December 1′ and replaced these with examples from the instructional design field,
Shot comprehensive video interviews with three experienced instructional design project managers that include stories and bits of wisdom on each of the book’s chapter topics and compiled text transcripts of each of the videos,
Completed a word-for-word re-editing that improved the readability of the book,
Created text-to-speech audio recordings of each chapter section,
Replaced (c) photos throughout the book with CC licensed photos,
Added a Glossary of key terms,
Updated and modernized the ‘Technology Tools for Project Management’ portion of the book, and
Created an automated process for scraping content from the live PM4ID site and converting the entire book into ePub, Kindle, PDF, and downloadable HTML formats nightly.

If this new textbook isn’t the best OER revise/remix ever, I’d like to know what is! Really. Leave links in the comments below.

[EU] Commission presents new Rethinking Education strategy

[EU] Commission presents new Rethinking Education strategy | OER Resources: open ebooks & OER resources for open educations & research | Scoop.it

"Digital learning and recent trends in Open Educational Resources (OER) are enabling fundamental changes in the education world, expanding the educational offer beyond its traditional formats and borders. New ways of learning, characterised by personalisation, engagement, use of digital media, collaboration, bottom-up practices and where the learner or teacher is a creator of learning content are emerging, facilitated by the exponential growth in OER available via the internet. Europe should exploit the potential of OER much more than is currently the case. This requires good computer skills, but some Member States are still lagging behind as seen in the Education and Training Monitor 2012, with 9 Member States with over 50% of 16-74 year olds with no or low computer skills. While the use of ICT in education and training has been high on the policy agenda, critical elements are not in place to enable digital learning and OER to be mainstreamed across all education and training sectors. A coherent strategy at EU level could address the scope, size and complexity of the challenges in support of actions of the Member States and the entire chain of stakeholders."

Theory and Practice of Online Learning

Theory and Practice of Online Learning | OER Resources: open ebooks & OER resources for open educations & research | Scoop.it
heory and Practice of Online Learning, edited by Terry Anderson and Fathi Elloumi, is concerned with assisting providers of online education with useful tools to carry out the teaching and learning transactions online. It presents, in an easily readable form, the theory, administration, tools, and methods of designing and delivering learning online. By doing so, the authors bring to the teaching community a valuable product which should go a long way in popularizing the use of the learning technologies.
Education, more than any other human endeavor, should be a real and lasting beneficiary of the ICT revolution. However the potential of this revolution can only be realized if those engaged in delivering education are knowledgeable, skilled, and able to apply these technologies effectively and efficiently. Despite the loud rhetoric of recent times, the uptake of learning technologies by the educational community is rather slow, reflecting partly the low levels of investment, in money and time, in the training of educational workers by individuals and their institutions, as well as the paucity of training materials on the subject. This publication, with its clarity and detail, greatly enhances our knowledge of the issues and our skills in addressing them.
