Discovering LETEC corpora

This article explains how to discover and become acquainted with the large set of LETEC corpora which are available in the open-access Mulce (MULtimodal Corpus Exchange) repository. The latter corpora have been collected over the past 12 years and are diverse in terms of the types of online learning situations and the types of Learner Computer Interactions.

Results of the survey “CALL within the Digital Humanities: considering CALL journals, research data and the sharing of research results”

Taking the opportunity of this communication to Eurocall 2013 (Chanier 2013), colleagues who were subscribers to the EUROCALL and CALICO mailing lists were invited to participate in an online survey. Here are the results of this survey.
It collected attitudes and opinions of CALL researchers related to issues on multilingual aspects of CALL literature, open access to publication, scientific process linking publications and data, access and reuse of data on learning situations where the researcher/teacher did not participated in the first instance, acknowledgement of research related to work on data.

IJTEL : lessons learned in five years by the Mulce project

Wednesday 4 July 2012 by Thierry CHANIER

In order to make replication possible for interaction analysis in
online learning, the French project named Mulce (2007–2010) and its team
worked on requirements for research data to be shareable. We defined a
Learning & Teaching Corpus (LETEC) as a package containing the data issued
from an online course, the contextual information and metadata, necessary to
make these data visible, shareable and reusable. These human, technical and
ethical requirements are presented in this paper. We briefly present the
structure of a corpus and the repository we developed to share these corpora.
Related works are also described and we show how conditions evolved
between 2006 and 2011. This leads us to report on how the Mulce project was
faced with four particular challenges and to suggest acceptable solutions for
computer scientists and researchers in the humanities: both concerned by data
sharing in the Technology Enhanced Learning community.

Our first anonymizer source code now available

Friday 3 February 2012 by Christophe Reffay

This article shortly presents the first software tool, developed in java by the LIUM laboratory. This software supports researchers to anonymize a set of (textual) interaction (chat/mail/forum). The source code is offered (as is) to the community, but, this software is no longer maintained.

Sticef "Structuring learning & teaching corpora (LETEC) for the support of research results share"

Wednesday 24 August 2011 by Thierry CHANIER
ABSTRACT : When analyzing situated interactions in online learning, one should link the data to some contextual information of the learning situation. This is an essential condition if we wish to construct a research object that would become usable by various research teams and disciplines and (...)
