Openess and Portfolio Technology
- 1. Openess and Portfolio Technology Darren Cambridge George Mason University
- 2. Overview Open content: Multimedia Open architecture: Integration Open standards: Interoperability Open services: Distribution
- 3. Open Content Portfolio pedagogy and assessment practice values Student ownership and control Authentic evidence Diverse evidence Implies a wide variety of file formats and authoring tools Challenging to support
- 4. Supporting Open Content Portfolio studios Clemson University LaGuardia Community College Multimedia writing centers University of Michigan Archival formats for long-term storage PDF-A
- 5. Open Architecture Portfolio systems are integrative Can make use of data from multiple academic and administrative systems Can provide data to same systems Ease of integration depends on both systems Increased openess decreases complexity of integration
- 6. Degrees of Openess Closed Dependent on a single vendor for integration Requires relationship between vendors if products from different companies Offers APIs Some data and functions exposed Documentation may an issue Depends on proprietary decision on both ends Supports open standards and specifications Less dependent on both ends Open source Fully customizable
- 7. Open Source Software Open source software (OSS) programs are applications that are distributed with their source code, giving users the freedom to run the program for any purpose, to study and modify the program, and to freely distribute copies of the original or modified programs You probably use OSS everyday Email = sendmail Web server = Apache
- 8. Drivers of OSS in Education Tight budgets (Coppola and Neely) Desire for freedom from vendor control Lack of innovation Collaboration technology that enables virtual teamwork Development technologies that support modularity and interoperability Proven business models Coherence with academic culture
- 9. In Search of a Better Model… Community Source Projects Partnering Organizations Higher Ed Coordination Open IP Objective…sustainable economics and innovation for satisfied users … for how we pay and what we get. Software is not free. Bundled IP & Support Creating Software Sustaining Software Licensing Fees Maintenance Fees Commercial Coordination Closed IP Unbundled IP & Support + Commercial Support Options
- 10. OSS as Scholarship OSS has the three characteristics of scholarship Made public Subjected to peer review Available for reuse (Shulman) OSS is part of a larger movement to reconceive teaching and learning as scholarly work Assessment is also part of this movement
- 11. Open Standards and Specifications Social software specifications RSS, Atom Friend of a Friend (FOAF) Social software APIs eLearning specifications IMS ePortfolio IMS Tool Portability
- 12. Portfolio as Digital Composition An ePortfolio is a digital composition A message in a rhetorical situation The product of the author’s agency Integral Not just a repository Arrangement and design matter Explains and predicts
- 13. Social Software Specifications Lightweight and flexible Excellent support for Atomization Distribution Aggregation Little support for Synthesis Contextualization
- 14. IMS ePortfolio Final version 1.0 approved by IMS Technical Advisory Board June 20, 2005 Captures the essential elements of an ePortfolio discussed earlier Accommodates diverse purposes Complicated Will require development of application profiles
- 15. Scope Focus on portability of portfolios as integral wholes Services out of scope Integrates and expands on existing specifications XML binding Revisions anticipated based on evidence from actual practice
- 16. Components of a Portfolio A collection of heterogeneous parts Associated with an owner A set of relationships between the parts Views Selections of parts and relationships for a purpose Presentations Instructions on how an audience experiences a view
- 17. Portfolio Part Finally Other LIP:Relationship Activity Competency Goal Product Accessibility FROM LIP … .. etc ACCLIP New Assertion Reflexion Participation (Data model in binding – based on Enterprise Services Group) Rubric Rubric Cell (uses RDCEO)
- 18. Relationship Types Basics shows-up Supplements Supports precedes Assessments and Evidence Attests Evaluates Evidences Commentary reflects-on Showcasing Presents Motivation aims-at (Categorization by CETIS)
- 19. Packaging Uses Organisation/Title to identify resources for Views Presentations Owners Relationships portfolioParts
- 20. Packaging Example Naming Convention for content-types Title
- 21. Implementing IMS ePortfolio Chris Arnett, Open Source Portfolio Initiative
- 22. IMS Tool Interoperability Enables use of external tools and services within a learning environment Simple demonstrator at Alt-I-Lab 2005 Initial release Fall 2005 ePortfolio community should generate requirements for further development
- 23. From Scott Wilson’s workblog http://www.cetis.ac.uk/members/scott/blogview?entry=20050603020705
- 24. Open Services Service Orientated Architectures to support portfolio development and use Examples: Skills Profiling Web Service Web Services for Reflective Learning Challenge: Integrity
- 25. Sharing Goals Through 43 Things Easy to share goals to and from a portfolio using RSS and 43 Things API Such sharing divorces the shared goal from its relationships to other objects and the portfolio as an integral whole Portfolio services must contextualize information within synthesized composition http://www.43things.com/
