  1. DIVERSE Ben Trott Max Woollard 26th October 2011

  2. Aims for this session • Understand what DIVERSE is • Understand how DIVERSE can benefit you • Understand how to use DIVERSE • Understand how DIVERSE links to Component Based Software Engineering • To be aware of the advantages and disadvantages of CBSE

  3. What is DIVERSE? • DIVERSE: Development and Integration of Varying Educational Resources and Student Engagement. • DIVERSE is a social collaboration based virtual learning tool. • DIVERSE is all about getting students more involved with their studies. • Student as Producer

  4. What is DIVERSE? • DIVERSE is a tool for constructing resource clouds. • DIVERSE allows students to interact with resources and collaborate together • DIVERSE aims to make the student experience more interactive.

  5. Resource Clouds • A resource cloud is created for each topic • Students add new resources to this cloud • Those they feel are relevant to the ‘cloud topic’ • Students can vote on resources which will effect the resource icon • A link icon is automatically added depending on the resource type

  6. Resource Clouds • The size of the icon on a cloud determines its subject specific usefulness: • As voted by the students themselves • Smallest – deemed least useful/relevant • Largest – deemed most useful/relevant

  7. An Example Resource Cloud

  8. Demonstration

  9. DIVERSE & CBSE • DIVERSE utilises many external web services • OAuth: for user authentication • Nucleus: for student information • Linking You: for link shortening & analytics • Facebook: for sharing links • Twitter: for sharing links • WebSnapr: for web previews • Google Analytics: for statistics

  10. DIVERSE & CBSE • DIVERSE has no knowledge of these services • DIVERSE relies on the API provided by the external services • This is ok  • CBSE means DIVERSE does not need to know implementation details of these external services.

  11. Example • DIVERSE uses student data from nucleus to personalise the users experience. • DIVERSE does not know the inner workings of nucleus, or have direct access to student information. • Instead DIVERSE uses nucleus’s API: • E.g. • https://nucleus.online.lincoln.ac.uk/person/basic

  12. DIVERSE & CBSE

  13. Example: Student Details

  14. Example Analytics • Google Analytics is completely external from DIVERSE and therefore we have no input or control over how it works • It is a complete Blackbox • Perfect example of component based

  15. Advantages of CBSE • Avoids reinventing the wheel • Saves time and resources • Reduces development time • Simplifies maintenance • Changes to external components do not effect DIVERSE, so long as the original API is still used. • Easy to swap out obsolete components

  16. Disadvantages of CBSE • Customising components can be limiting • E.g. Google analytics • Dependency on external developers • Becomes an issue when there is no alternatives • Risk of poisoned components • Components containing malicious code

  17. Summary • DIVERSE is a new online tool to help you engage in your studies • Provides a new starting point for research & assignments • Peer reviewed resources • DIVERSE is a simple case study for illustrating the importance of components in web applications

  18. Workshop • During Fridays workshop you’ll be testing DIVERSE on a sample cloud. • We’ll have a quick questionnaire for you to complete • Optionally we are also looking for volunteers to take part in a short interview about your experience with DIVERSE

  19. Any Questions?
