Darko Grabar Accessible e-learning in the cloud

  1. 1. Accessible e-learning in the Cloud The Spatial Extent of Knowledge – World-Wide-LearningDarko Grabar, University of Zagreb, Faculty of Organization and InformaticsTechnucation – ICT in Science in Society Activities, Porto, 2012
  2. 2. Outline • Background info  About me  Why this topic • e-Learning today • What is “The Cloud?” • E-learning and the cloud  Case study  Advantages of the “e-Learning Cloud”  Problems • Practical examples
  3. 3. Background info: About me• Darko Grabar  Working at University of Zagreb, Faculty of Organization and Informatics  Head of Software Development Center and E-learning Support Center  Softer developer with strong relation to Open source and e-learning  Involved in e-learning projects since 2005  Participated in development of several e-learning strategies at institutional and country wide level  Part of several Croatian working bodies that deals with Open Source / Open Access and e-learning
  4. 4. Background info: Why this topic• This is what I do  Trying to be one step ahead of teachers by predicting future usage of ICT in learning• E-learning is at its turn point  New Web 2.0 technologies  LMS crisis  Bigger gap between rich and poor• Cloud technologies are ready  To be used by masses  To provide cheep, reliable and powerful services
  5. 5. E-learning today E-learning is a process of education (learning and teaching process) conducted using the Information and Communication Technology which improves the quality of the process itself and the quality of its result
  6. 6. E-learning today Web today
  7. 7. E-learning today E-learning today
  8. 8. E-learning todayFuture of e-learning LMSExternal tools ePortfoliosand Apps External content
  9. 9. E-learning today Why the future is not here? What are the problems?Software is availableHardware can support itNetwork is readyThere are people that know how to use newtechnologiesStudents/children are demanding it
  10. 10. E-learning today Resources! Ifthere would be enough resources: • Schools would hire more teachers • They would have experts in ICT and e-learning • They would have appropriate ICT equipment • Teachers would have time to produce quality e-learning materials • ICT staff would have time to provide top-of the line environment for e-learning • Students/pupils would be able to use it • And the list goes on…
  11. 11. E-learning today
  12. 12. E-learning today• So what’s wrong with e-learning today?  Outdated technology  Closed systems  Slow innovation  Lack of resources  Money  ICT resources  People  Available only to “privileged”
  13. 13. What is “The Cloud?”
  14. 14. What is “The Cloud?” E-learning professional End user ICT support
  15. 15. What is “The Cloud?” Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet) Cloud computing entrusts remote services with a users data, software and computation Wikipedia
  16. 16. What is “The Cloud?” It is “a mechanism for delivering scalable business services that execute on a decentralized computing fabric composed of commodity software and hardware”
  17. 17. What is “The Cloud?” It is a “pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources ”
  18. 18. What is “The Cloud?” Not a new idea
  19. 19. What is “The Cloud?” Relies on Virtualization
  20. 20. What is “The Cloud?”
  21. 21. What is “The Cloud?”• Infrastructure as a service (IaaS)• Software as a service (SaaS)• Platform as a service (PaaS)• Storage as a service (STaaS)• Desktop virtualization• Data as a service (DaaS)• Database as a service (DBaaS)• Test environment as a service (TEaaS)• API as a service (APIaaS)• Security as a service (SECaaS)• Backend as a service (BaaS)
  22. 22. What is “The Cloud?” Analogy How many of you build your house?
  23. 23. What is “The Cloud?” Analogy Are you renting/owning apartment?
  24. 24. What is “The Cloud?”AdvantagesCost EffectiveUnlimited resourcesSpeed & ScalesFast innovationBackup and RecoveryAutomatic software integrationEasy Access
  25. 25. What is “The Cloud?”DisadvantagesChange in thinkingSecurity in the CloudTechnical IssuesInflexibilityCost
  26. 26. What is “The Cloud?” Is it only for large Corporations?
  27. 27. E-learning and the cloud How to make e-learning accessible and affordable
  28. 28. E-learning and the cloudCase: teaching ICTGoal: To provide advanced education in the field of ICT (programming and multimedia) to students in schools in the form of blended e- learning course.We want to teach two courses  Big Data Processing  3D ModelingRequirements:• Learning Management System for delivering courses• E-Portofilo system for student collaboration• High computing power needed for large files manipulation and 3D modeling• Large data storage• High speed network
  29. 29. E-learning and the cloudCase: teaching ICTLet’s do it “traditional way”We will need:• Server• Install LMS, e-portfolio, databases, ...• High speed network connection• Computer classroom  Screen projector  20 computers (workstation class): fast processor, 8GB of RAM (min), 500GB disk, fast graphic card  Windows and Linux OS  Install all required software on each computer  Fast local LAN connected to high speed broadband connection• What about when working from home?

  31. 31. E-learning and the cloudCase: teaching ICTLet’s do it “Cloud way”We will need:• Cloud environment with configured applications• Computer classroom  Screen projector  20 low end computers: enough processing power to run OS and browser  Any OS capable of running standard browser or Cloud native client  Network connection (2-3 > Mbps)• What about when working from home?  You can, from any computer (even smart phone or tablet)
