Informal Learning at the Workplace via Adaptive Video Milos Kravcik, Petru Nicolaescu, Aarij Siddiqui, Ralf Klamma Advanced Community Information Systems (ACIS) RWTH Aachen University, Germany lastname@dbis.rwth-aachen.de 11th Joint European Summer School on Technology Enhanced Learning (JTEL 2015) July 6-10 Ischia, Italy
  2. 2. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 2 Workshop Learning Outcomes • Understand nuts & bolts of informal learning • Understand how outcomes of collaborative work at workplace can be used to scaffold informal learning • Apply adaptive video strategies to support learning • Apply your own ideas for personalization
  3. 3. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 3 Agenda  Motivation  Aims of Learning Layers Project  Semantic Video Annotation  Adaptive Video Presentation  Task in Groups  Presentations
  4. 4. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 4 Motivation  Discussions with stakeholders revealed requirements that can be solved by using multimedia in workplace scenarios  How to support informal learning at the workplace by video annotation and video adaptation techniques?  Challenge: select scenes relevant in a particular context and present them accordingly
  5. 5. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 5 Workplace Learning  Workplace learning is mostly informal – No set objective in terms of learning outcomes – Not intentional from the learner’s standpoint  It maintains important principles of education – Authenticity, Engagement, Demonstration  Domain knowledge of experts is often ill-structured – Content complexity – Irregularity of application contexts  Cognitive Flexibility Theory (Spiro & Jehng, 1990) – ability to spontaneously restructure one's knowledge, in many ways, in adaptive response to radically changing situational demands Spiro, R. J., & Jehng, J. C. (1990). Cognitive flexibility and hypertext: Theory and technology for the nonlinear and multidimensional traversal of complex subject matter.

  6. 6. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 6 EU FP7 Learning Layers Project  How can we scale up video tagging to support informal learning at the work place  Objectives – Mobile creation of videos with learning materials (physical-digital world) – Tag the non-obvious for informal learning in communities (social media layer) – Scaffold meaningful learning by exploiting semantic tagging information (social semantic layer)  Two regional clusters – Construction (Germany) – Healthcare (UK) http://learning-layers.eu/
  7. 7. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 7 Video Annotation: Sevianno 2.0  Annotation types: Place, Object, Agent, Concept, Event  Simple (textual) annotations
  8. 8. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 8 Multimedia Metadata User Interface
  9. 9. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 9 Multimedia Annotation System Architecture  3-tier architecture  Cloud-enabled solutions  Advantages – Separation of concerns – Scalability – Rapid development & deployment – Application customization
  10. 10. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 10 Use-Case Adaptive Video Presentation  A Web-based video adaptation tool – Informal learning support – Adaptive video presentation based on – User profile (preferences) – Collaboratively created video annotations  Objective – Choose relevant segments from different videos to form an adaptive video, personalized for a particular user
  11. 11. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 11 Model of Adaptive Learning Aroyo, L., Dolog, P., Houben, G. J., Kravcik, M., Naeve, A., Nilsson, M., & Wild, F. (2006). Interoperability in personalized adaptive learning. Educational Technology & Society, 9(2), 4-18.
  12. 12. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 12 Adaptive Video Presentation  Aim: adapt annotated videos according to the current demands & meta-data on Content, User, Context  FOSP Method to specify adaptation strategies – Filter: take only relevant components (segments) – Order: order them accordingly – Select: choose from alternative representations – Present: responsive design Damjanovic, V. & Kravcik, M.

  13. 13. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 13 Video Adaptation in Vaptor Filtered based on user’s language preferences Ranked for relevance, based on user’s interests, location, duration, … Extracts annotations based on the search query
  14. 14. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 14 DEMO
  15. 15. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 15 TASK
  16. 16. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 16 Task: Adaptation Strategies  Team up  Choose a scenario for applying video adaptation – E.g. Construction, Healthcare – Keep in mind the learning objective  Specify a video adaptation strategy for learning – Situational context – User information needed – How to acquire the information – What users should specify (explicit info) – What can automatically collected (implicit info) – Video presentation – How to filter & prioritize information – How to present (any important UI concerns)
  17. 17. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 17 Relevant Information  User profile information => User Metadata  Video annotations (type, content) => Video Metadata  Contextual information (location, weather) => Context  Adaptation strategies => Adaptive Presentation – Filter: select relevant segments – Order: rank information according to different criteria – Select: choose most suitable representation (media, perspective) – Present: responsive design (parallel vs. sequential)
  18. 18. Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 18 Presentations Top concepts get featured on Learning Layers blog
