To sum up… Environment for manipulating replayables Versatile tool for researchers
Many data formats and extension possibilities
Currently used to analyse many kinds of data Three of our own data sets (collaborative note-taking,
collaborative design, children’s explanations) Argumentation (Switzerland) Forums (Hong-Kong) Blogs (Denmark) LEAD project (G.B., Paris, The Netherlands) Boundary object for discussion between epistemologies
(series of workshops at ICLS, CSCL, Alpine Rendez-Vous) French traditionnal dancing

Computer Science in Tatiana
Model the researcher’s practice Model of analysis artefacts which will support
this practice Implementation of this model
Necessary? How to evaluate?
Most of the implementation is just softwareengineering Good if this tool is actually supposed to help people Bad for a young researcher Actually a quite hard engineering problem
![Page 21: Tatiana - EducTiceeductice.ens-lyon.fr/.../200905tatiana...GregDyke.pdf · Tatiana Trace Analysis Tool for Interaction Analysts Gregory Dyke, Ecole des Mines de Saint-Etienne Kristine](https://reader033.vdocuments.net/reader033/viewer/2022041800/5e507cacbd8137622c6afc4e/html5/thumbnails/21.jpg)
21
Who else could have done Tatiana?
Need to: Understand researcher’s activity Model that activity Produce an implementation Have time to work on one project
Software companies, some day? Practices are too diverse, no money
Big european project? Still need someone to implement
Social sciences researcher? Maybe…

Problems What is a model ? (what are acceptable answers in
different research disciplines) Subdisciplines of computer science tend to have a very
narrow view of what appropriate results are Human usage of technology is always Somebody Else’s
Problem
TEL … what about the learning? For interdisciplinarity to happen, both disciplines need to
find research questions Implementations often need several sub-disciplines …and a good deal of software engineering Defining what should be implemented is hard -> most of
the time you won’t get what you wanted
