Educational Search and DiscoverEd

Alex Kozak, June 25th, 2010

Last week in the vuDAT building at Michigan State University, a group of developers interested in educational search and discovery got together to contribute code (in what’s commonly called a code sprint) to Creative Commons’ DiscoverEd project. Readers interested in the technical details about our work last week can find daily posts on CC LabsDay 1, Day 2, and Day 3.

DiscoverEd is a semantic enhanced search prototype. What does that mean practically? Let’s say you’re a ninth grade biology teacher interested in finding education resources about cell organelles to hand out to students. How would you go about that?

If you’re web savvy, you might open up a search engine like Google, Yahoo, or Bing and search for “cell organelles”. You’d find a lot of resources (Google alone finds over 11 million pages!), but which do you choose to investigate further? It’s time consuming and difficult to sift through search results for resources that have certain properties you might be interested in, like being appropriate for 9th graders, being under a CC license that allows you to modify the resource and share changes, or being written in English or Spanish, for example. As you throw up your hands in dismay, you might think “Can’t someone do this for me?!”

DiscoverEd is an educational search prototype that does exactly that, by searching metadata about educational resources. It provides a way to sift through search results based on specific qualities like what license it’s under, the education level, or subject.

Compare search results for “cell organelles” in Google, Yahoo, Bing, and now in DiscoverEd. You can see that finding CC licensed educational resources is friendlier because of the available metadata accompanying each result.

While most search engines rely solely on algorithmic analyses of resources, DiscoverEd can incorporate data provided by the resource publisher or curator. As long as curators and publishers follow some basic standards, metadata can be consumed and displayed by DiscoverEd. These formats (e.g. RDFa) allow otherwise unrelated educational projects, curators, and repositories to express facts about their resources in the same format so that tools (like DiscoverEd) can use that data for useful purposes (like search and discovery).

Creative Commons believes an open web following open standards leads to better outcomes for everyone. Our vision for the web is that everyone following interoperable standards, whether they be legal standards like the CC licenses or technical standards like CC REL and RDFa, will result in a platform that enables social and technical innovation in the same way that HTTP and HTML enabled change. DiscoverEd is a project that allows us to explore ways to improve search for OER, and simultaneously demonstrate the utility of structured data.

Continued development of DiscoverEd is supported by the AgShare project, funded by a grant from The Gates Foundation. Creative Commons thanks MSU, vuDAT, MSU Global, and the participants in the DiscoverEd sprint last week for their support.

Preparing Your Educational Resources for DiscoverEd

Jane Park, November 5th, 2009

ded-sbsIn July, CC Learn officially launched DiscoverEd, a search prototype that provides scalable search and discovery for educational resources on the web. We blogged about it again during Back to School week, emphasizing the future of search and discovery of educational resources and how we hoped DiscoverEd would catalyze efforts in that direction. Since then, we have been working with various organizations and projects who want to include their resources into DiscoverEd, and through all the back and forth about feeds and mark-up–essentially what’s required to get your stuff included for greater discovery–we realized we could streamline the process by putting some necessary information into a brief document.

Preparing Your Educational Resources for DiscoverEd is second in the CC Learn Step by Step Guides series, which is part of our larger Productions schema. It is a basic guide for those interested in preparing their resources for inclusion into search engines like DiscoverEd that utilize structured data. It is targeted at people or institutions interested in making their digitally published educational resources more discoverable. Though the document contains technical language and sample XHTML and RDFa, it’s really not all too complicated. Basically, you just need one of the right feeds to start, which you can then copy and paste the link of into ODEPO (the Open Database of Educational Projects and Organizations). ODEPO is hosted on OpenED, the community site for open education. It’s a wiki, so anyone can create an account and add their project or organization to the database.

But the guide explains all that, (as does the DiscoverEd FAQ) and the alternatives–which include contacting us directly. DiscoverEd already pulls from a number of institutions and repositories, and as it expands we hope to improve its search capabilities. Any feedback is welcome.

Food Safety Knowledge Network calls for OER

Jane Park, September 10th, 2009

The Food Safety Knowledge network is seeking CC licensed open educational resources in the area of food safety. From their announcement:

“With the increasing demand for safe food and the growing globalization of food production and manufacturing, there is a great need for no-cost, accessible training and educational resources for food safety professionals, especially those working in developing countries where such access is not readily available. Michigan State University and the Global Food Safety Initiative have partnered together to create the Food Safety Knowledge Network (FSKN), a directory of open educational resources in the area of food safety, which will make quality content easily and efficiently findable.

FSKN will use ccLearn’s DiscoverEd search tool to draw resources from reliable sources. These materials will be curated by experts in the field as well as aligned to a set of core competencies for food safety managers so that the users can identify the specific area the resource covers as well as trust the quality of the content. This fall, the Food Safety Knowledge Network will be pilot tested to support implementation of supplier training at the pre-certification level in developing countries including India and China.

If you have or know of food safety resources to share, please contact Sunnie Kim at kiml@msu.edu.”

All resources that the FSKN integrates into DiscoverEd will have a CC license, with all FSKN site content available via CC BY.

Back to School Conclusion: The Open Trajectory of Learning

Alex Kozak, September 4th, 2009

As students around the world return to school, ccLearn blogs about the evolving education landscape, ongoing projects to improve educational resources, education technology, and the future of education. Browse the “Back to School” tag for more posts in this series.

Today’s predictions about the future of learning might eventually seem as preposterous as early 20th century predictions of flying cars and robot butlers. But what we sometimes forget is that our vision for the future today will ultimately shape the outcomes of tomorrow–not in a causal, deterministic way, but in an enabling way. By sharing our hopes and dreams for an open future for learning, we foster an environment in which it can happen.

At ccLearn, we strongly believe that the future for education and learning is one that includes technical, legal, and social openness.

The spaces in which teaching and learning occur are increasingly moving towards technical openness by running open source software, integrating machine readable metadata, and adopting open formats. Schools, colleges, and universities involved in open courseware, wikis, and other organizations engaged in online knowledge delivery are beginning to embrace RDFa and metadata standards like ccREL, open video codecs, open document formats, and open software solutions. More open technology continues to be developed, and there is no indication that this will stop or slow down.

Members of the global education community have been moving towards legal openness by converging on Creative Commons licenses that allow sustainable redistribution and remixing as the de facto licensing standard. This phenomenon is international- Creative Commons has been ported to 51 countries (7 in progress), with CC licensed educational resources being used all over the world. Although ccLearn found in our recent report “What status for ‘open’?” that some institutions have some homework to do on what it means to be open, we are well on the road towards a robust and scalable legal standard for open educational resources.

Perhaps most powerfully, we are beginning to see a move towards social openness in educational institutions in the prototyping of new models for learning involvement, organization, and assessment that maximizes the availability of learning to all people, everywhere. By leveraging the power of online organization and open content, often times coupled with a willingness to re-conceptualize what it means to be an educator, new possibilities for learning will emerge, leading to a more educated world.

We can’t fully predict today what kinds of practices, pedagogies, and technologies open education will enable tomorrow. But we are in a position to claim that our goal for an open future enables the creation of these new and better practices, technologies, and social structures.

ccLearn would like to thank The William and Flora Hewlett Foundation for their continued support of open education, the Creative Commons staff who make our work possible, and all of you for your continued support of a truly global commons. We hope that you all continue to contribute to open source learning software, embrace open formats, license your educational works with Creative Commons licenses, and get engaged in the world movement towards an open future for learning.


En Estados Unidos están de regreso al colegio este mes y con este contexto en ccLearn, han venido publicando una serie de entradas algunas de ellas ya quedaron comentadas en español, creo que justifica comentar y traducir lo pertinente:

De regreso al colegio, conclusiones: El camino abierto para el aprendizaje

La entrada de cierre para el ciclo de ccLearn sobre el regreso al colegio esta nuevamente a cargo de Alex Kozak quien indica como desde ccLearn, se cree firmemente en un futuro del proceso de educación y aprendizaje atravesado por la idea de apertura en lo técnico, lo legal y lo social.

Los espacios en los que la docencia y el aprendizaje se dan para Kozak están migrando a estándares abiertos en con el uso de software open source, integrando metadatos que pueden ser leídos por las máquinas y adoptando formatos abiertos. Escuelas, Universidades y en general instituciones de educación superior que desarrollan courseware abiertos, wikis y otras organizaciones involucradas en los procesos de disponer del conocimiento a través de la red están empezando a adoptar RDFa y estandares de metadatos como ccREL, codecs para video abierto, formatos abiertos de editores de textos, y soluciones de software abierto o libre.

De otro lado la comunidad global del sector educativo se esta moviendo hacia la apertura legal, sus decisiones de adopción de licencias Creative Commons como un estándar converge para permitir la redistribución y mezcla de los recursos . Este es un fenómeno internacional- Creative Commons se ha adaptado al sistema legal de 51 países (7 mas lo están haciendo), los recursos educativos licenciados con CC se usan por todo el mundo. En todo caso se debe considerar que ccLearn encontró en su informe “What status for ‘open’?” que algunas instituciones todavía tienen que revisar lo que significa abierto, pero que el camino hacia estándares de apertura en los recursos educativos esta en marcha.

Para Kozak incluso lo llamativo es que se esta empezando a ver una mayor apertura en lo social en relación con los pilotos educativos en los nuevos modelos que las instituciones ensayan. A la hora de abordar el proceso de aprendizaje, la organizacion, y valoracion de estos pilotos están maximizando la idea de hacerlo accesible a cualquiera en cualquier lugar. Kozak cree que apalancando la capacidad de las organizaciones en linea y del contenido abierto, junto con el cada vez mas frecuente deseo de re-conceptualizar lo que significa ser docente, nuevas posibilidades para el aprendizaje surgirán para llevarnos a un mundo mas educado.

Para Kozak aunque no podamos predecir las practicas, pedagogías y tecnologías que favorecerá una educación abierta mañana si podemos decir que la meta de un futuro abierto permitirá la creación de esas nuevas practicas, tecnologías y estructuras sociales.

Breve comentario desde mi propia óptica

Aunque en regiones como América Latina nos hacen falta datos para asumir como ciertas muchas de las afirmaciones de Kozak para el mundo anglosajón lo cierto es que la sensación que hay en el ambiente es que muchas de sus conclusiones pueden ser extensibles a nuestra realidad,

De hecho algunos otras de las entradas de este ciclo de regreso al colegio que hizo ccLearn se referían a proyectos concretos que mostraban proyectos y practicas abiertas (Vital signs y el caso de los libros de texto). Creo que deberíamos visibilizar algunas de las muchas iniciativas que están ocurriendo en nuestra región para conocerlas y aprender de ellas… espero poder hacerlo muy pronto! (si tienen ideas dejen su comentario y hagamos seguimiento de ellas juntos)

Back to School: DiscoverEd

Alex Kozak, September 2nd, 2009

As students around the world return to school, ccLearn blogs about the evolving education landscape, ongoing projects to improve educational resources, education technology, and the future of education. Browse the “Back to School” tag for more posts in this series.

Years from now, what will it mean for teachers to prep for a new school-year? Will they be reviewing digital textbooks? Collaborating online with colleagues in revising and adapting digital lesson plans? Upgrading operating systems and software on classroom laptops? Scouring the net for those perfect open educational materials to print or distribute to students?

Everyone might have their own image of how preparation for a new school year will look, but the current excitement about open and digital educational resources indicates that teachers are ready for a new model.

As textbooks and learning materials move online, the copyright status of those resources becomes more important to teachers. At ccLearn, the education program at Creative Commons, we strongly believe that developing a global education commons of openly licensed educational resources is the best solution to the legal and technical challenges that teachers face when trying to share and adapt educational resources. But how exactly will teachers be able to find and share open educational resources? After all, a resource simply being accessible online isn’t itself enough for it to be easily discoverable.

ccLearn has developed a prototype search engine, DiscoverEd, that provides one solution to this challenge.

DiscoverEd provides scalable search and discovery for educational resources on the web. Results come from institutional and third-party repositories who have expended time and resources curating metadata about resources. These curators either create or aggregate educational resources and maintain information about them. Metadata, including the license and subject information available, are exposed in the result set.

We are particularly interested in open educational resources (OER) and are collaborating with other OER projects to improve search and discovery capabilities for OER, using DiscoverEd and other available tools.

Our search engine is a prototype and shouldn’t been seen as the only solution to OER search and discovery. But assuming that categorization and assessment of OER are embedded at the point of publication as open metadata, the DiscoverEd model is a powerful and scalable method for discovering and utilizing those data.

To learn more about DiscoverEd, you can explore the DiscoverEd site, FAQ, or read our report entitled “Enhanced Search for Educational Resources: A Perspective and a Prototype from ccLearn“.

De Regreso al colegio, DiscoverEd

En esta entrada Alex Kozak aborda la solución que ofrece ccLearn, el programa educativo de Creative Commnons, para apoyar los problemas legales y técnicos que enfrentan los profesores cuando buscan recursos digitales y abiertos en el universo de Internet donde encontrar no es tan sencillo. Se trata del buscador piloto DiscoverEd que busca enfrentar este reto.

DiscoverEd es un buscador para recursos educativos en la red. El buscador revisa repositorios de terceros que han dedicado tiempo y esfuerzo a curar los metadatos de los recursos. Estos curadores crean o cosechan los recursos y conservan la información sobre ellos en metadatos, incluyendo la información sobre la licencia y el tema que es presentada como resultado en el proceso de búsqueda.

DiscoverEd se ocupa esencialmente de proyectos abiertos, de Recursos Educativos Abiertos (REA o OER por sus siglas en ingles) y colabora con otros proyectos de este tipo para mejorar los resultados en la búsqueda y descubrimiento de estos recursos..

Kosak finaliza indicando que este es un piloto que no debe ser visto como la única solución para la búsqueda y descubrimiento de REA pero, considerando que la categorización y valoración de los recursos se hace en el punto de publicación a través de metadatos abiertos, cree que DiscoverEd sera un modelo poderoso y escalable para encontrar y usar los datos.

La información sobre el proyecto esta por ahora en ingles, puede revisarse en DiscoverEd site, FAQ, o en el informe “Enhanced Search for Educational Resources: A Perspective and a Prototype from ccLearn”

Launching DiscoverEd—an education search prototype

Jane Park, July 20th, 2009

Last year, we demoed DiscoverEd along with ODEPO at the Open Education Conference in Logan, Utah. CTO Nathan Yergler explained its various features and some if its issues. Since then, it’s been worked on extensively and some of its functionality has improved. We’ve even gone ahead and produced a white paper, which explains what DiscoverEd is, what it aims to do, and what you can do to help improve it.

With the production of this white paper, we would like to officially announce the launch of DiscoverEd. Entirely open source, DiscoverEd is an experimental project from ccLearn which attempts to provide scalable search and discovery for educational resources on the web. Metadata, including the license and subject information available, are exposed in the result set.

As noted above, DiscoverEd has been discussed at a few meetings already, so this launch is mainly to help spread the word and to spark additional conversation. If you are an educator or anyone else looking for educational resources, it is available for immediate use and we welcome your feedback.

We want to emphasize that DiscoverEd is a prototype intended to explore how structured data may be used to enhance the search experience. We are by no means launching this as a definitive tool; in fact, we intend just the opposite. We are launching this so that others in the search and discovery space can contribute to this project. There are a number of known issues which we would love help on, especially since we think the community’s input and work should go into shaping future versions of this tool. This tool is currently intended for educational resources, but there is no reason anyone can’t take and adapt it for other purposes.

Where do the search results come from?

Results come from institutional and third party repositories who have expended time and resources curating the metadata. These curators either create or aggregate educational resources and maintain information about them. If you’re a producer or curator of educational resources and would like to be included in the search contact us. If you’re an educator, we want to hear from you. What works for you? What’s broken? What can be improved?
