Open-source approaches now appear to be migrating from the fringe to the mainstream in the education market.

Blackboard has acquired Moodlerooms and Netspot and launched an open-source services group within the company. Pearson is touting its 鈥淥penClass鈥� learning management system. Instructure has unveiled the source code for its Canvas platform.

But as companies make such moves, experts contend that the definition of what constitutes 鈥渙pen鈥� is changing. And in some cases, companies are using the term in products that are not actually open source to capitalize on the popularity of the concept.

鈥淭here are multiple definitions of open that are confusing buyers and watering down the message,鈥� says Philip D. Hill, the ed-tech consultant, analyst, and co-founder of MindWires Consulting. Hill has been following LMS companies for more than eight years and writes about developments in that market on the e-Literate blog.

Learning management systems provide an online portal for classrooms, serving many administrative functions for educators as well as allowing students to view assignments, grades, and learning materials. In some cases, LMS products can be used to deliver entire courses.

A purely open-source product allows a user of the product to both view and modify its source code. One major advantage to open-source software is that it is distributed for free, and for many cash-strapped educators and schools, there is a strong link between the concept of 鈥渙pen鈥� and free, which is a major draw to such products.

That link may explain the use of the word 鈥渙pen鈥� in a product like Pearson鈥檚 OpenClass. While it does not claim to be open source, it is available for free for anyone to download and use. However, the source code is not viewable and cannot be modified by users.

OpenClass, a cloud-based LMS that was launched by the London-based educational publishing giant in October 2011, allows educators to import and export data, so it is open in that sense, says Hill, but does not fit the purely open-source category because of its proprietary source code.

By contrast, the LMS platform Canvas offered by Instructure, a Sandy, Utah-based ed-tech startup, is technically open source. But even though Instructure allows the code to be viewed, the company makes most of the changes to the code in-house, says Hill. While Canvas was initially marketed primarily to higher education, it is now sold in the K-12 market, too.

But do schools care if products are staying true to the philosophy of open source?

鈥淚t matters a lot less than it used to鈥攁nd that frustrates a lot of the open-source community,鈥� says Hill. 鈥淲hat people care a lot more about now is the cost. They鈥檙e also sensitive in that they want to have easy-to-use features.鈥�

鈥淐anvas has really changed the game in terms of usability,鈥� he adds. 鈥淎nd the market seems to be saying, 鈥業t鈥檚 fine if we鈥檙e not contributing code.鈥� 鈥�

Usability Challenges

A majority of the schools that use Canvas do not host the code themselves as open-source products allow them to do, but rely on Instructure鈥檚 cloud-based hosting instead, says Brian Whitmer, the co-founder and chief product officer of the company.

Cloud computing allows schools to pay a third party to host software on separate servers that the third party maintains and troubleshoots in the event of an outage. Many schools do not have the staffing or technical expertise to maintain their own servers, and that need has helped create a market for cloud-based hosting services.

鈥淭ypically, what happens with an open-source product is that the usability isn鈥檛 where it should be,鈥� Whitmer says. 鈥淏ut when you have a company like Instructure that鈥檚 backing the open-source offering, it鈥檚 not like you鈥檙e sacrificing anything to have an open-source product.鈥�

Although schools may not actively be taking advantage of it, being open source does provide some benefits to the user, he contends. For instance, it allows users to build extensions into Canvas, giving teachers the power to pull in resources from other parts of the Web, he says, making the LMS more flexible.

Audrey Watters, the author of the Hack Education blog, says she has noticed a change in the way schools view open-source products.

鈥淎 lot of schools are nervous about open source because they feel as though they just don鈥檛 have the knowledgeable folks on staff to help manage it,鈥� she says. 鈥淭hat鈥檚 been the appeal of something like Moodlerooms, which has developed a good support network of services to help people. They handle a lot of the service and architecture and implementation for schools.鈥�

However, the open-source LMS Moodle has been criticized by many schools as being clunky and hard to use, says Watters. But while schools five years ago had to choose between proprietary Blackboard and open-source Moodle, she says, now there are more options, including the proprietary LMS company Desire2Learn as well as other products such as Instructure鈥檚 Canvas.

In addition, Watters sees Google as Blackboard鈥檚 main competitor in today鈥檚 market.

鈥淕oogle Apps fulfills a lot of the things that a school would want in an online system鈥攁 calendar, email, Google Docs,鈥� she says. 鈥淏lackboard feels like an older tool, and they鈥檙e really having to scramble to remain relevant.鈥�

Seeking Open Sources

Blackboard Inc.'s acquisition of Moodlerooms and Netspot鈥攖wo of the largest providers of the Moodle LMS鈥攁s well as the launch of Blackboard Education Open Source Services, which provides hosting, customer support, implementation, training, and migration services for open-source technologies, marked a new commitment from the company to the open-source concept. The move initially drew worries from skeptics who believed that the proprietary company would ultimately fold the open-source offerings into its line of products, as it did after its acquisition of the videoconferencing companies Wimba and Elluminate in 2010.

But so far, the Washington-based Blackboard has remained true to its promise to support the open-source offerings, says Hill from MindWires Consulting.

鈥淲e鈥檝e seen that Blackboard is not taking over as a Trojan horse trying to take away the openness of Moodlerooms, and companies are still acting in the best interest of open-source technology,鈥� he says.

Sanjeev Ahuja, the vice president of marketing for Blackboard K-12, says the motivation behind the acquisition was to better serve the elementary and secondary market.

鈥淭he way I look at it, if you鈥檙e truly to serve the entire K-12 education market, you have to have a variety of products to fit their needs,鈥� he says.

A large portion of schools serve less than 200 students each, says Ahuja. 鈥淭hey can鈥檛 afford a big investment in technology.鈥�

Open-source technologies, which are typically free but require technical expertise to maintain and run, are a powerful way to help schools that cannot afford a proprietary LMS to find a solution that works for them, Ahuja says. 鈥淥pen source is a lower investment, and then [schools] can build on it and grow on it,鈥� he says.

But as Watters notes, many schools prefer to leave the hosting and maintenance of the open-source software to a third party, which is where Blackboard steps in.

"[Schools] are looking for stability with a hosted solution,鈥� says Ahuja. 鈥淲hen things go wrong, typically if you鈥檙e hosting it in-house, it takes a while to get it back up and running,鈥� whereas with an outside host, it may take only a few minutes.

Ultimately, Ahuja says, it comes down to the total cost of ownership.

鈥淚f you have an underlying code base that gets you kick-started, as you start using the technology, you鈥檒l need technological expertise,鈥� he says. 鈥淣othing in life is free.鈥�
