    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: Microbes as biological weapons for terrorism

Print This Post Print This Post -

bioterror.jpgA learn node of up-to-date knowledge of what homeland security is up against in the area of manipulating naturally occurring deadly materials is provided in the OpenCourseware at Johns Hopkins Bloomberg School of Public Health in a course called Biological Agents of Water and Foodbourne Bioterrorism. The Notes to first lecture include this alarming overview:

- The microorganisms and toxins that could act as biological weapons are naturally occurring.
- The agents that could potentially be used as biological weapons are diverse and widely distributed in nature and include −
–viruses, bacteria, fungi, and protozoa −
–the toxins produced by many microbes
-These microbes are found naturally in soils, waters, plants, and animals.

The Bioterrorism section of the website of the Centers for Disease Control and Prevention is a cluster of the latest expert material for the topic, including specific bioterrorism agents. The sections about agents are superb learnodes for their topics. For example the botulism information is broad and deep concerning the disease, its prevention and treatment.
