• Course framework, Authoring Wotan / WotEd
• Testing Evaluation Simulog / ASquare
• Free-text / NLP - Willow, Willed
• Collaboration Col-Tangow, CoMoLe
• Other projects
• Group formation - Together
• Plagiarism deterrence Ac
• Peer-reviewed Grading Pacs
• Collaboration with PAWS group
• Proposal to integrate Wotan Cumulate

3
Adaptive Hypermedia

• Wotan provides
• Course user administration, UM monitoring
• Exercise creation interface
• Adaptation and course delivery / monitoring
• Course adaptation currently mimics Tangow
• Default 'AdaptationEngine' can use others

4
WOTAN

• Access roles admin, author, student
• Course structure tasks, rules ( seq),
  fragments, versions
• UMs namespaces, values
• Adaptation engines, expressions
• Session offshoring Atenea / Willow
• Wotan services programatic interfaces

5
WOTED

• Authoring tool for Wotan/Tangow courses
• Information overload (clustered) graphs
• Direct manipulation of structure
• Based on Clover MVC for free
• Talks to Wotan services
• Course UM events gt monitoring

6
SimuLog

• Allow authors to test the evaluation tool
• Are anomalous patterns being detected?
• Generates logs imitating student behavior
• Uses an internal copy of Wotan
• No need for an actual server
• Author can parametrize log randomness

7
Asquare (Author Assistant)?

• A2 provides a higher level of abstraction
• Domain knowledge
• Anomalies
• Heuristics
• Where to look for anomalies
• A2 help to instructors who are not experts in
  Data Mining.
• Link simulog-a2.ppt

8
Willow (adaptive Atenea)?

• Diana Pérez, Enrique Alfonseca
• Teacher supplies free-text questions, and several
  different correct answers for each.
• System extracts and generates concept map
• Student answers questions,
• Textual feedback,
• Can examine own concept map overlay
• Multiple UM views similar to MabbotBull
• More info pres-diana.ppt

9
ColTangow, CoMoLe

• Rosa Carro, Estefanía Martín
• ColTangow
• Collaborative tasks
• Choice of tools for tasks depending on profile
• Extension to rule system to support it
• Work-in-progress
• CoMoLe
• Generalization for mobile devices
• Profile incorporates context information

10
Other Tools - rationale

• EPS/UAM computer science typical course
• As a TA, would like to improve
• Group creation
• Plagiarism prevention
• Feedback, Grading, Motivation

11
Together

• Pedro Paredes
• Group formation based on learning styles
• Specifically, group diversity using S-Felderman
• Work-in-progress
• More information - TOGETHER.ppt

12
AC Plagiarism Prevention

• Similarity between two submissions
• Default tokenize compression distance
• Other metrics / metric combinations available
• Analysis with
• List / Filtered graph / Individual Histograms
• Submission acquisition apples to apples
• Virtual filesystems, sophisticated boolean
  filters

13
PACS Assignment Grading

• Groups in Subjects Assignments in Subjects
• Teacher defines, for each assignment
• Grading criteria (reviews) Review grading
  criteria
• Formal Judge, Functional Judge
• Deadlines
• Initial flowFeedback multiple peer
  reviews, clear criteria, comments and more
  comments
• Mechanism almost there Questions on policy

14
Collaboration with PAWS group

• Platforms
• Wotan as an activity for the KT ecosystem(or as
  a portal to enable access to KT activities)?
• Future UM testing / datamining (Javier)?
• Technology
• Graph representation, Pdf to text, Plagiarism
  detection, Similarity visualization, Java plugin
  mechanism, Java parsers, Java session
  persistance, Jail environment, Free-text question
  grading (Diana)?
• Content
• Interested in C, Java, SQL content for local KT
  installation

15
The End

• Questions
• Comments
• Suggestions
• Feedback on the sweets
• ( Thanks to all interviewees)?
