Motivation:

TEL as a Research Community

� Observable change of communication

– New events: EC-TEL, JTEL Summer School, Professional Training

Facts, Alpine-Rendezvous, …

– New journals: IEEE Transactions on Learning Technologies,

Journal of Technology Enhanced Learning, …

– New media: Blogs, Twitter, Facebook, LinkedIn, …

� Funding situation in FP 6 – FP 7

– Several NoE: KALEIDOSCOPE, PROLEARN, STELLAR, GALA

– Overcoming fragmentation: What happened so far?

– Driving excellence: What should happen?

� Tools for the TEL community

– Online, Open Source, Open Access

Research Context

Mapping and roadmapping for TEL

Understanding the current TEL landscape

Strong and weak signals for change at different levels

Different data sources

Different methods, e.g. Delphi, Community modeling,

Text analysis, Social Network Analysis, etc.

Data Sources Overview

TeLLNet



Prof. Dr. M. Jarke

I5-MD-0512-7

TEL Publications

� Published paper represents (finished) research work

� Points of interest

– Venue analysis � important TEL venues

– Co-authorships � collaboration networks

– Paper topics

� Data set:

– DBLP Bibliography integrated with CiteSeerX

TeLLNet

TEL Publication Venues – Approach

� Seed venue: ECTEL

� Author overlap := fraction of authors of the smaller venue

who also have paper(s) in the other (larger) venue

� Identify venues that have at least 10% author “overlap”

with ECTEL; repeat

TEL Conference Communities –

Current State

TEL conferences exhibit mixed patterns

– Some moving towards focused topology

– Some stuck in the bonding/emergence phase

Cross-Source Comparison

� Comparison of key words in the three sources

– Blogs: post content (bursts)

– Projects: project description

– Papers: title

� Question: what is the frontier outlet?

� Method:

– Time window: 2005–2010

– Top 50 terms per year per source

– Distinct term list

– Compare first appearances

TeLLNet



Prof. Dr. M. Jarke

I5-MD-0512-40

Bursts in All Sources

� 22 of 228 terms appear in all sources

� Findings:– Papers are frontier outlet (except for social, game, classroom)

– Projects lag (particularly for teach, student, game, classroom)

– Blogs lag despite immediate publication (except game, classroom)

Main Findings

� Blogosphere– Mostly about existing work (conferences, workshops, projects, papers)

– Top cited blogs outside Europe

– Don’t blog, write papers

� Publications– Important role of conferences for dissemination and community building

(adopted from CS)

– TEL conferences exhibit SNA measures of young, developing communities

– Premium outlet

� Projects– Tightly knit collaboration network

– Organizations find non genuine TEL calls to bridge funding gaps

� JTEL gathers the crème de la crème of TEL ☺☺☺☺

Upcoming Work

� Extend data sources

– Social media, e.g. twitter)

– Projects, e.g. LLP, JISC, PSP …)

– Papers, e.g. including full text; additional indices

� Integrate data sources

– Entities, e.g. blogger = author = affiliate = project worker)

– Analytic approaches, e.g. probabilistic topic modeling (in

progress)

� Improve end-user tools, e.g. browsing / exploration

based on topics, more interactive widgets
