    About Findability

    As 21st century education adapts to its online future, the edu sector is learning to work under the network laws that make the best study knowledge findable. Findability emerges naturally from educational resources embedded in a network when these 7 elements are present.

    Digital - Educational materials that are printed are outside of the digital online commons where findability arises.

    Unbundled - Findability works bests with the smallest pieces of content, so bundles like curricula, courses, and PDFs stifle findabiity.

    Open - To be findable, content must be open in the one Web global commons, with no barriers of cost, subscription, or copyright.

    SEOed - Search Engine Optimization with keywords and linking attracts search engine spiders and boosts rankings on search engine results pages.

    Juiced - Webpages getting higher search engine page ranks from links by educators judging their content as superior.

    Networked - Nodes of learning content are syndicated (RSS), virally spread, and connected into social networks.

    Mobilized - Nodes of learning content are becoming findable to millions, and potentially billions, of new learners by being optimized for mobile phones.

    The learn nodes posted on this blog are models that show how you can increase findabiity for open educational resources.

  • The LEARN NODE is a tool for creating findability

    The illustration below shows a learn node, which you can use as an educator to make webpages more findable. The top little circles illustrate links out to content nodes related to the subject of the large circle. Bottom left, experts connect to the node affirming its quality - giving it juice. Bottom right, a student connects to the node to learn the subject of its content.

Learn node: steam technology history and practices

Print This Post Print This Post -

This learn node links out to “The story of steam power [that] stretches from attempts to harness atmospheric pressure in the 1600s to the steam turbines we depend upon today.” (Science Museum Energy Hall, source of the flywheel image above.) A steam industry source, spiraxsarco, provides an excellent steam overview. A US Department of Energy Best Practices page for Steam provides extensive practical information and explains:

Over 45% of all the fuel burned by U.S. manufacturers is consumed to raise steam. Steam is used to heat raw materials and treat semi-finished products. It is also a power source for equipment, as well as for building heat and electricity generation. Many manufacturing facilities can recapture energy through the installation of more efficient steam equipment and processes.

An interesting page on nuclear warfare at Notre Dame Open Courseware includes the mention that military tanks were tried with steam power, but it was the internal combustion engine that made tanks successful.
