Educational objects definition

Educational Objects: Definition

  • software for education, training or expertise transfer

  • characterized by:

    • discoverability

    • modularity

    • interoperability

    • reusability


Educational objects discoverability

Educational Objects: Discoverability

  • ability to find an object

  • characterized by standardized, searchable information, i.e. metadata

  • permits discovery by electronic search

  • identifies

    • creator

    • purpose

    • technical requirements

    • subject classification


Educational objects modularity

Educational Objects: Modularity

  • characteristics: free standing, non-sequential, coherent

  • functions independently without external resources

  • useable with creator assistance


Educational objects modularity1

Educational Objects: Modularity

  • two approaches

    • black-box: inner workings hidden

      • two interfaces:

        • public: no change to object, use as

        • parameter: object appearance and/or functionality modified slightly

          • degree of change determined by creator

      • object code unchanged

    • gray-box: code provided

      • user can edit it

      • recompile / publish

      • slightly different object or application


Educational objects interoperability

Educational Objects: Interoperability

  • refers to two scales:

    • large: works on variety of hardware platforms, operating systems and/or Web browsers

    • smaller scale: must exchange information with other objects built to same open standard

  • objects standardized in manner of connection not operation


Educational objects reusability

Educational Objects: Reusability

  • foundation for creating applications from objects

  • not a primary characteristic

    • ensured if object has the three main characteristics

      • discoverability

      • modularity

      • interoperability


Building learning applications

Building Learning Applications

  • objects can be reused, recombined, and customized

  • allows rapid creation of multimedia-rich educational resources

  • example: wave propagation object

    • lab exercise on seismic waves

    • lecture on interior of the Earth

    • study-aid on ocean wave refraction

  • key is access and availability of objects


Using eos to create learning applications

Using EOs to Create Learning Applications


Using eos to create learning applications1

Using EOs to Create Learning Applications


E ducational o bject e conomy eoe

Educational Object Economy (EOE)

  • constitutes:

    • design

    • creation

    • exchange

  • promoted by Web sites

    • EOE (Educational Object Economy)

    • MERLOT (Multimedia Educational Resources for Learning and Online Teaching)


Educational objects benefits

Educational Objects: Benefits

  • flexible

  • updates, searches & content management easy

  • customization

  • competency-based learning

  • increased value


Educational object economy eoe

Educational Object Economy (EOE)

  • not reviewed, commented on or combined with others

  • availability varies widely with discipline

    • 1411 physics

    • 324 computer science

    • 157 health science

  • limited adoption by Earth sciences

    • 47 for Earth science


Educational object economy eoe1

Educational Object Economy (EOE)

  • three factors contribute to slow adoption and growth of an EOE

    • small number of educators willing to acquire skills to create educational objects

    • social and legal barriers

    • duplication of effort


Earth science eoe

Earth Science EOE

  • Earth science must develop its own EOE

  • many have roles in its creation

    • developers/producers

    • educators/users

    • administrators

    • funding agencies


Earth science eoe developers

Earth Science EOE: Developers

  • characterize their objects with metadata

    • make it as specific as possible

    • complete

  • insure modularity

  • make objects interoperable

    • function across range of platforms

    • exchange data according to standards

  • post objects to EOE Web sites


Earth science eoe educators

Earth Science EOE: Educators

  • assist developers

    • provide functional and pedagogical feedback

    • indicate types of objects needed

    • share ideas for objects

  • use objects to create customized learning applications

    • disseminate these applications

  • share tips and hints by commenting on objects and applications


Earth science eoe administrators

Earth Science EOE: Administrators

  • recognize object development and dissemination as an important academic endeavor

  • make resources available for technology development projects, e.g. time, money, software/hardware

  • develop formal guidelines to evaluate object development for tenure and promotion decisions


Earth science eoe funding agencies

Earth Science EOE: Funding Agencies

  • support developer/user teams

  • promote projects to assess educational object effectiveness

  • encourage efforts to develop ways to disseminate education objects to the widest possible audience

    • specific EOE Earth science Web site

    • inclusion in digital library efforts


Summary

Summary

  • educational objects are standalone software “chunks”

  • characterized by: discoverability, modularity, interoperability, reusability

  • reused and recombined to produce learning applications

  • Earth science has not adopted EOE model
