Web Science guest lecture
Using Web Science for Educational Research(and vice versa :-)
Dr Christian Bokhove
About me
• Dr Christian Bokhove
• Lecturer in Mathematics Education at Southampton Education School
• Background maths and computer science, teacher secondary school for years
• Use of ICT to support learning
• Use of technology for analysing learning
Aim of this presentation
• Impression of 4 topics I’m (more or less ;-) working on
• Topics transcend education
A. Modeling software and analyzing children’s drawings (with University of Twente, Netherlands)
B. Educational datamining: mining log files, automatic text book analysis
C. Social network analysis (classrooms, organizations)
(D. Tools for data analysis)
A. Modeling software
• After visit of Prof. Van Joolingen
• SimSketch: www.modeldrawing.eu

Analyzing drawingsEXAMPLE 1
EXAMPLE 2(Prof. van Joolingen)
Challenge
• We have modelling software that produces drawings/models
• Can we do analyses of drawings automatically?
• So: datamining, pattern recognition?
• Project to work on improving modeling software and automatic analysis
B. Educational datamining
• Log files, electronic books, student actions
• What can we say about their ‘learning behaviour’? Or about textbooks?
• Learning Analytics/datamining: using algorithms to explore this
Example 1
• Log files with student activity
• Classification, predictions (e.g. bored, on-task, Ryan Baker has done a lot of work on this)
• European project where Learning Analytics important role
USING RAPIDMINER
Example 2
• Online resources or a textbook (non-edu: tweets)
• Can we extract its meaning?
• e.g. Latent semantic analysis
USING R
Challenge
• A lot of digital resources are used in education; they create a lot of data (‘Big Data’)
• What can we learn from usage?
• Project to work on using aforementioned methodologies to analyze student work
C. Social Network Analysis
• Started with social sciences (networks)
• Then Watts and Strogatz took it into physics
• Now very multidisciplinary
• See Freeman (2004)
• Dynamic Social Network Analysis: over time, statistical models, simulations, animations
Freeman, L.C. (2004). The Development of Social Network Analysis: A Study in the Sociology of Science. Vancouver: Empirical Press.
Example
• Using toolso Ro Gephio nodeXLo UCIneto Pajeko ….McFarland, D.A. (2001). Student Resistance: How the Formal and Informal Organization of Classrooms Facilitate Everyday

Challenge
• Use existing methodologies from Social Network Analysis (SNA) and apply them to social sciences (here: education)
• Use existing metrics from SNA to explore (community) patterns and new metrics (for me: for educational effectiveness, for example)
• Project proposal to apply SNA to educational context
D. Tools for data analysis
• Would also love to build capacity for all these tools we useo Ro Rapidminero nodeXL, Gephi, UCInet, Pajeko etc.
Let me know, we can look at the options: [email protected] 32 Room 2035
