(re)Inventing the free online textbook

by on May 10, 2013 in Open Textbook Challenge, Opinion

Picard facepalm cookies“First came free online courses. Now come…free online textbooks” (“Coursera to offer students free online textbooks, with conditions” | WaPo). Call us picky, but the implication that free textbooks are an xMOOC innovation is a bit frustrating, especially coming a couple days before we announced the release of a free-and-open, no-strings-attached college mathematics textbook.

Even more especially after we’ve spent a couple years seeking, vetting, and deploying free, open textbooks, in free, open-as-we-can-get-’em courses.

Superlatively especially given that most all of those great books we’ve found have been developed, improved, and shared by a score or two of individuals and institutions, whose missions in part or whole involve the production, collection, and/or dissemination of high quality free textbooks.

Q&A with Dr. Wissam Raji, author of An Introductory Course in Elementary Number Theory

by on May 10, 2013 in Open Textbook Challenge, Profiles

Dr. Wissam Raji, Ph.D.

“[T]he subject is presented in a way where no mathematical background is required with the exception of the last three chapters.”

“[B]elieve in [your] capabilities. It is not about the school you attend, it is all about the inner will to achieve and passion you have for the subject you are studying.”

With our release of An Introductory Course in Elementary Number Theory, we asked the author, Dr. Wissam Raji, Ph.D., a few questions about himself, his work, the textbook, and his thoughts on education. Learn more about the book here.

Dr. Raji, can you tell us a bit about yourself?

I am currently an assistant professor of Mathematics at the American University of Beirut (AUB), Lebanon and a fellow at the Center for Advanced Mathematical Sciences at AUB. I moved to the States in 2002 to join Temple University in Philadelphia where I obtained my Ph.D. in mathematics in 2006. My field of research is analytic number theory. I am also the president and founder of an NGO called the Center for Development, Democracy and Governance (CDDG), operating in Lebanon, whose main mission is to promote good democratic practices and rural development.

What problems do you work on in mathematics?

I am a number theorist whose main research concentration is the theory of automorphic forms and automorphic integrals. In the last four years, I have been working on Eichler isomorphism theorems between the space of modular forms and the cohomology group of period polynomials. I teach graduate and undergraduate courses in Mathematics and I also supervise graduate students seeking Master’s degrees.

Why is number theory important?

Number theory constitutes the building blocks of the fundamentals in Mathematics. It is the theory of integers, and integers are where it all started. Kronecker said: “God made integers and the rest is the work of men.”

What about for non-mathematicians?

To non-mathematicians, number theory is a brain teaser. It deals with problems which in many cases are easy to describe but hard to solve. Learning number theory disciplines the mind and creates a systematic way of thinking that attracts many people to learn more about mathematics.

What led you to write this textbook?

After using several books to teach a course on elementary number theory, I could not really find a book that addresses beginners such that one can learn the subject independently. Moreover, many books contain extra material that is good but unnecessary for students to tackle in a beginner course.

This text is intended for undegraduate students majoring in Mathematics and computer science. However, the subject is presented in a way where no mathematical background is required with the exception of the last three chapters. As a result, anybody who wishes to learn the subject can smoothly follow all the concepts presented.

How did you learn about the Open Textbook Challenge?

I was sent an email from Saylor Foundation asking me if I would referee math courses in analysis. I visited the website and found out about the open textbook challenge.

Were you previously familiar with open education initiatives or open education resources (OER)?

Not really. It was my first time learning about open education initiatives other than official videos posted on YouTube by selected professors in some U.S. universities.

How do you envision the role of higher education in the twenty-first century? How must it change? How must it stay the same?

I do believe that the evolution in education should go in harmony with all the technological development. With increasingly easy access to the internet, it is becoming clear that access for education will be free.

How do you see your role as an educator?

As an educator, I believe I should always be up to date on the developments in education. Moreover, I should always promote the belief that education should be free for everybody and thus it will be one’s choice to either develop their educational skills or not.

Any advice for learners?

My advice to students is to believe in their capabilities. It is not about the school you attend, it is all about the inner will to achieve and passion you have for the subject you are studying.

A Case Study in Obstacles to and Strategies for Negotiating the Relicensing of Third-Party Content

by on April 9, 2013 in About

Over the past four years, the Saylor Foundation has developed over 300* college level courses, made up of nearly 28,000 educational objects (essays, textbooks, videos, assessments, etc.).  Initially, our goal was to use the wide breadth of resources available online to build these courses.  We encouraged the use of openly licensed and public domain materials, in order to give our users the most flexibility.  However, in an effort to include the highest quality materials, we also allowed the use of open-access (i.e. protected by copyright, but freely available) material.  But populating our courses with third-party links led to some instability, especially when websites changed or content was removed.  In an effort to combat this issue, the Saylor Foundation launched an initiative aimed at persuading content creators (professors, organizations, universities, etc.) to either:

  1. Relicense their content under a Creative Commons license; or
  2. License their content in a way that would allow the Foundation to mirror it.

In our early negotiation experiences, we found content creators almost universally in favor of making a separate agreement with the Foundation over adopting an open license.  Many of them were unfamiliar with the concept of an open license, and even after detailed explanations, they remained resistant.  Chief concerns included the loss of control of materials, commercial reproduction, and loss of traffic/ad revenue.

Loss of Control

Discussing open licenses is a battle of perception.  Many content creators come into the conversation with preconceived ideas about the quality of open content (generally, as inferior), or of the alleged direct correlation between open licenses and instances of illegal use.  They worry that by allowing others to edit and change their content, their reputations will suffer.  Despite the “Removal of Attribution” clause in the licenses, they are quick to point out that “Google doesn’t forget”; in fact, Google often times caches documents permanently.  Another worry comes from Content Creators who regularly update their content.  There is no infrastructure in place to compel users that have downloaded older and outdated versions of a work to use the new one instead.  Having multiple versions with differing information can present a confusing picture to students, and that is a persistent worry to educators.

Commercial Reproduction

This issue is fairly straightforward.  It can be very difficult to disabuse professors of the notion that there are commercial publishers waiting in the wings to scoop up anything licensed under a CC-BY license and charge unsuspecting students for it.  While they are sympathetic to the idea of open, they do not want to enrich folks that would profit off of exploiting students.  While it is true that publishing companies would need to compete with the free version, it is not overly cynical for professors to imagine publishing companies using their entrenched paths of distribution to take advantage of students.

Loss of Traffic/Ad Revenue

This concern occurs most often with content creators who have posted videos to YouTube and rely on the advertisement revenue that they derive from the platform.  Unfortunately, there is no system on the YouTube platform to credit an “original poster” for views of a reposted video.  Therefore, any content creator dependent upon views (or traffic, in the case of Google Ads) loses out financially by applying an open license.  Such a system of tracking views, and crediting an original source would be a huge boon to open licensing, as it would incentivize its use tremendously.

With the launch of the Open Textbook Challenge (OTC), the Saylor Foundation stepped into the realm of paying a content creator to relicense his or her work under a Creative Commons license.  We were willing to offer a $20,000 honorarium to a textbook author who relicensed his or her text under a Creative Commons Attribution (CC BY 3.0) license and aligned that text to our course structure.  This initiative was met with limited success.  While there were numerous submissions, many did not meet the approval of our review committee.  Reviewers expressed concerns over both the quality of the writing, as well as the content.  Overall, four textbooks were accepted: Mathematical Analysis I by Dr. Elias Zakon, Elementary Linear Algebra and Linear Algebra: Theory and Applications by Dr. Kenneth Kuttler, and Computer Networking: Principles, Protocol, and Practice by Olivier Bonaventure.

Despite the modest success of the OTC, the Foundation realized that we needed a more flexible tool to address some of the content gaps in our courses.  This led to the development of Saylor’s Direct Relicensing program.  Through this program, the Saylor Foundation expanded the types of content for which it was willing to offer a monetary honorarium in exchange for relicensing under a Creative Commons license.  We created a scale through which we determined the value of a particular collection of resources.  This scale ($500-$10,000) was based upon two factors: course necessity and the license the content contributor was willing to choose.  We offered greater compensation for a more open license (BY, BY-SA) than would for a more limiting one (BY-NC, BY-NC-SA).  However, we chose not to incentivize relicensing under any of the no derivative licenses.  We determined that it would be more cost effective to simply create our own replacement resources under a more open license than to accept the terms of a no derivative license.

This new approach yielded positive results.  Over the course of a year, the Foundation succeeded in relicensing over 5000 pages of content, and over 300 lecture videos in six unique disciplines.  By offering compensation, we were able to mitigate the second and third issues discussed above.  This was enough to change the minds of many of the content creators that we had previously contacted.  In the winter of 2012, the Saylor Foundation switched to a model that only permits the use of openly licensed or public domain materials in its courses.  By using the methods discussed above (Outreach, the OTC, and Direct Relicensing) and creating new openly licensed content ourselves, the Saylor Foundation hopes to have courses that are entirely open, re-mixable, and redistributable.

Saylor’s “Wild Ambition” – Now in Chronicle Flavor.

by on November 13, 2012 in About, News & Events, Partnerships

Saylor.org credit options - StraighterLine, Excelsior College, CLEP, etc.

Apologies if you’ve caught this already in the social media streams…this is just to share that we’ve made a print-edition debut in the Chronicle of Higher Education:

A Dot-Com Entrepreneur’s Wild Ambition: Drive Education Costs to Zero

For our part, we’re just thrilled to mention it. But for anyone interested in the origins of Saylor.org, why we do what we do, and especially in the “wild ambition” that carries us forward, you’ll definitely want to check this out.

Here are some of the high points and takeaways:

  • We are nitroglycerine (but probably more stable)
  • 267 free college courses, with K-12 and grad programs on the way
  • Our trustee, Michael Saylor, conceived the idea back in 2000 (and someone counted us out, but here we are)
  • Study Groups!
  • Affordable college credit possibilities via Excelsior College, StraighterLine, CLEP, and more.
  • We’re also a gadfly, apparently.

There you have it, folks. We’re a nitroglycerine gadfly with “global implications”.

Hey, we’re cool like that.
