  2. The WME Concept

  3. The WME Architecture WME : Web-based Mathematics Education MeML: Mathematics Education Markup Language MESP: Mathematics Education Service Protocol

  4. MeML and WME Services

  5. Relation with WME Pilot Site WME Pilot Site Modeling (analysis, design) feedback T-Model Server-side Requirements WME Pilot Site Deployment (code, delivery, feedback) WME Service Definition T-Model Client-side Requirements MeML Design WME Service Construction MeML Plug-in Construction Integration feedback feedback

  6. Mathematics Education Markup Language • MeML aims to provide effective and expressive means for structuring and delivering mathematics education content on the Web. • MeML supports authoring, storing, processing, and exchanging mathematics education materials over Web. • MeML is a XML language. It can be used with HTML, MathML, etc.

  7. Mathematics Education Markup Language – cont.

  8. Processing MeML Page Download (Browser) MeML Translation (XSLT Processor) HTML+Script+Object Loading (Browser, MeML Plug-in) DOM Local Interaction (Browser, Plug-in) Remote WME Services User

  9. MeML Plug-in: Woodpecker • A prototype of MeML Processor as Browser Plug-in or ActiveX Control • Translating MeML content into XHTML / Script / in-page objects • Supporting import/export “Manipulatives” and page customization • Being interaction agent between user and WME service • Simulating MeML DOM

  10. Woodpecker MeML Page Update Event Handlers [ MeMLInit(), MeMLEvent() ] DOM Methods / Properties Access Event MeMLFE MathGraph Computation Miscellaneous Controls Persistent Data Access WME Service Access Local Data Storage MESP ( Dynamic Link Library)

  11. WME Services • Generating dynamic content for MeML pages. • Supporting educational activities like online test, student performance assessment, etc. • Supporting online math computation with IAMC technologies. • Using MESP/SOAP as service accessing protocol

  12. Accessing WME Services

  13. Core WME Services • Account service • help author of MeML page to validate and identify page visitor • assign virtual passport to visitors which can be accepted by any WME server • deal with the relationship among student, teacher, and course. • Repository service • Provide general storing and retrieving service to dynamic data generated from educating activities. • Data is associated with MeML page URL, name and ID of MeML tag creating the data, and virtual passport of current page visitor. • The explanation to the created data depends on the corresponding MeML tag.

  14. Core WME Services • Computation service • Encapsulate online mathematics computation served by powerful compute engines like Maple, Maxima, etc. • Several compute engines can be accessed through one IAMC server which hides the difference of compute engines' interfaces. • Terminology service • Supplie formal and in-depth explanation to mathematics knowledge defined by content elements.

  18. Conclusion • MeML is an education-oriented XML language. It is designed for math teachers with basic knowledge of HTML page authoring. It could also greatly simplify coding work of advanced programmer. • MeML supports structural storage of education materials, dynamic and interoperable content creation, and online mathematics computation. • WME service provides a uniform interface to link education resources into MeML page. • WME technologies can facilitate the creating work of education pages and online courseware, support interoperation and customization of Internet education resource, and promote the online delivery of math education.
