Coordination & Interaction
Systems Group
SpeakUp
is a co-located
social media to
improve audience
interaction
speakup.info
graasp.euGraasp
a social media used as a
personal and collaborative
learning environment
Inquiry Learning Spaces
Teachers construct courses for their students by finding and
structuring relevant content
Content in Graasp
Teachers would like to
benefit from relevant
content uploaded by others
Students would like to
get relevant content

even when not included
How to suggest
relevant content
to users
?& keep them in control
Approach
“Learner-content interaction
is a defining characteristic of education …”
M. G. Moore. Editorial: Three types of interaction.The American Journal of Distance Education, 3(2):1–6, 1989.
”… it is the process of intellectually interacting with
content that results in changes in the learner’s
understanding, the learner’s perspective, or the
cognitive structures of the learner’s mind”
Recommenders for Learning
A review of 82 recommenders for learning [Drachsler et al 2015]
Discovering by the instructors relevant learning resources used by
students when learning, that are not part of the materials provided by
the instructor [Zaldivar et. al. 2011]

• Considered present terms to describe the content

• TF-IDF based on terms from the content

• Looked at one type of interaction (visit)

• No possibility to adjust recommendations by the user
Personalized recommendations of relevant knowledge assets based
on user interactions with content [El Helou et. al. 2010]

• Built user-content graph based on interactions

• Used modified PageRank to get relevant items

• Considered multiple types of interactions

• Did not look inside of the content

• No possibility to adjust recommendations by the user
No explicit identification of interests. No control over them.

Building Interests Profile
Providing Recommendations
Step 2. Use vector cosine similarity for scoring and ranking
Step 1. Compute TF-IDF for each term in the vectors
Step 0. Represent each content item concepts using the
document vector model
Implementation &
Evaluation
Graasp
AlchemyAPI for concept extraction
ActivityStreams / xAPI for Interaction Tracking
ElasticSearch for storage and recommendations
Open-source tools for text extraction
Implementation in Graasp
Preliminary Evaluation
• Six pre-service teachers, participants of a workshop on
inquiry-based learning
• They were newly registered users (no interaction data)
• Interacted for 2 hours
• Survey from three parts
1. General disposition towards the interests identification
and the interests-based recommender
2. System Usability Scale for the solution
3. Recommender Precision
Evaluation Outcomes
Complete results: https://goo.gl/Wes6uP
Would like to edit interests
Concerned about privacy
We use a 5-point Likert Scale
Evaluation Outcomes
Was easy to use
Easy to get started
Evaluation Outcomes
Misidentified concepts in popular content can push up
irrelevant concepts
Two groups:
relevant and
irrelevant interests
Two groups:
relevant and
irrelevant suggestions
Conclusions
• Proposed a general and scalable approach
deployable in systems where content and
interactions are available
• Allows users to modify the interests
• Implementation in a real system, can be used as a
guideline
• Preliminary evaluation in an authentic setting
Future Work
• Address misidentified concepts-related issues
• Learn optimal action weights
• Incorporate concept relevance score into similarity
• Substantial Evaluation
• Run a bigger scale evaluation
• Check not only precision, but as well recall
• Compare to existing approaches. Dataset?

  • 4. SpeakUp is a co-located social media to improve audience interaction speakup.info
  • 5. graasp.euGraasp a social media used as a personal and collaborative learning environment
  • 6. Inquiry Learning Spaces Teachers construct courses for their students by finding and structuring relevant content
  • 8. Teachers would like to benefit from relevant content uploaded by others Students would like to get relevant content
 even when not included
  • 9. How to suggest relevant content to users ?& keep them in control
  • 11. “Learner-content interaction is a defining characteristic of education …” M. G. Moore. Editorial: Three types of interaction.The American Journal of Distance Education, 3(2):1–6, 1989. ”… it is the process of intellectually interacting with content that results in changes in the learner’s understanding, the learner’s perspective, or the cognitive structures of the learner’s mind”
  • 12. Recommenders for Learning A review of 82 recommenders for learning [Drachsler et al 2015] Discovering by the instructors relevant learning resources used by students when learning, that are not part of the materials provided by the instructor [Zaldivar et. al. 2011] • Considered present terms to describe the content • TF-IDF based on terms from the content • Looked at one type of interaction (visit) • No possibility to adjust recommendations by the user Personalized recommendations of relevant knowledge assets based on user interactions with content [El Helou et. al. 2010] • Built user-content graph based on interactions • Used modified PageRank to get relevant items • Considered multiple types of interactions • Did not look inside of the content • No possibility to adjust recommendations by the user No explicit identification of interests. No control over them.

  • 20. Preliminary Evaluation • Six pre-service teachers, participants of a workshop on inquiry-based learning • They were newly registered users (no interaction data) • Interacted for 2 hours • Survey from three parts 1. General disposition towards the interests identification and the interests-based recommender 2. System Usability Scale for the solution 3. Recommender Precision
  • 21. Evaluation Outcomes Complete results: https://goo.gl/Wes6uP Would like to edit interests Concerned about privacy We use a 5-point Likert Scale
  • 22. Evaluation Outcomes Was easy to use Easy to get started
  • 23. Evaluation Outcomes Misidentified concepts in popular content can push up irrelevant concepts Two groups: relevant and irrelevant interests Two groups: relevant and irrelevant suggestions
  • 24. Conclusions • Proposed a general and scalable approach deployable in systems where content and interactions are available • Allows users to modify the interests • Implementation in a real system, can be used as a guideline • Preliminary evaluation in an authentic setting
  • 25. Future Work • Address misidentified concepts-related issues • Learn optimal action weights • Incorporate concept relevance score into similarity • Substantial Evaluation • Run a bigger scale evaluation • Check not only precision, but as well recall • Compare to existing approaches. Dataset?
