  2. What isPachyderm?

  3. Pachyderm is . . . ...an online tool for developing instructional and informational content. For authors • Create content by selecting a preferred template type and ‘populating’ it via a Web-based form. • Completed content may be ‘published’ to a Web site or delivered locally via CD-ROM. For student-users • Content accessed through a Web browser. • Only the Flash plug-in is required to access content.

  4. How doesPachyderm work?

  5. Pachyderm works by . . . • combining media from a content repository with • layout and formatting information from a user-selected template to • create a Macromedia Flash content object that can be displayed and manipulated in student-users’ Web browsers.

  6. To make this work, authors • . . . build media libraries, • . . . select a template and add content, and • . . . output (or publish) a completed file, ready to be delivered from a server or via some portable medium (e.g., CD-ROM).

  7. Some limitations of the current Pachyderm install • Multiple authorship and workgroup media sharingare both challenging • Workaround: Create a project- or group-specific account and share the login/password among team members • Distribution of the finished files can likewise present a challenge • They can be distributed from the Pachyderm server, but the process is cumbersome (not indexed or searchable) • Better solution: Package as .ZIP archive and unpack/store/distribute via Vista/Moodle, content-management system or standard Web server, or even CD-ROM.

  8. Build a Media Library (I)Log-In to Pachyderm

  9. Build a Media Library (II)Import Files

  10. Build a Media Library (III)Add Metadata 1

  11. Build a Media Library (IV)Add Metadata 2

  12. Select a Template and Add Content (I)Template-Based Authoring • Pachyderm uses a ‘parent-child’ authoring paradigm • Author’s selection of a ‘home screen’ template affects his or her choice of ‘linked screen’ looks • For templates, see the “Template Overview” at http://www.pachyderm.org/docs/PachyTemplateOverview.pdf

  13. Select a Template and Add Content (II)Template-Based Authoring • Pachyderm uses a ‘parent-child’ authoring paradigm (cont’d) • See also the “Grid-Based Template Workbook” at http://www.pachyderm.org/docs/gridtemplate.pdf • Match—as closely as possible—your choice of template with your pedagogic objectives • For example, 'slider' versus 'aspects'

  14. Select a Template and Add Content (III)Select a ‘Home Screen’

  15. Select a Template and Add Content (IV)I picked ‘Zoom'

  16. Select a Template and Add Content (V)Add Content

  17. Output a Completed File (I)When Completed, ‘Publish’

  18. Output a Completed File (II)Bundled Output

  19. Pachyderm ChallengesSummarized • File upload can be awkward • Template features, limits poorly documented • Text formatting problematic • Document length • A problem of mindset rather than a technical problem (scrolling features work well, just awkward for longer texts) • Multiple authorship not well supported • Templates can be difficult to construct

  20. Pachyderm 2.1.0Changes (Coming Soon) • Fully Section 508-compliant • Will require asset/project conversion • New templates, including • Limits on media-type/module length removed from existing templates • Timeline template; full-screen .SWF shell • Low-level interactives (games, quizzes, etc.) • 'Mid-ground' image + improved frame editor • Integration with the enterprise • Enhanced interoperability with existing/emerging systems • especially media/learning object repositories via OSIDs
