Share data treatment and analysis processes inTechnology enhanced learning

International audienceIn the context of our research team (multidisciplinary with numerous and various TEL systems), we have been working during the last three years on the design and implementation of an open platform to collect, save and share experimental data drawn from the interaction with TEL systems, which could build, save and share analysis processes executed on these data. From our point of view both data and analysis processes are worth to be stored and shared, and moreover have to be joined in a unique repository to get the whole picture. This communication presents the analysis processes part of the project. Sharing analysis processes, i.e. the whole complex process, is rather unusual, whereas contemporary platforms or software already propose generic algorithms to work on data (for instance with a statistical point of view or a data mining point of view). Hence, we attempt to model the main concepts of global treatments for experimental data analysis in order to collect, execute, save and then share them in a platform, dedicated to TEL Systems. The execution part is the most difficult and constraining part of our work. This needs to be implemented with a complex architecture. An important part of the communication is so devoted to the description of the architecture, and to the link between the global point of view of the whole process and the local point of view of elementary or specific algorithms used during the process. A short, but realistic, example of application of our platform is given, with the definition of a global process and the definition of an elementary algorithm used in the global process. The process is executed on real data leading to a graphical display of results, which are then briefly analyzed

The impact of nonverbal cues on mediated tutoring interaction: an experimental study

ISBN 978-83-60810-21-7International audienceVideo-mediated settings are more and more used in several mediated human activities, as teaching. Nevertheless, we do not deeply know yet the functions of nonverbal cues that these communication technologies make available to distant participants. The aim of this paper is to enrich the field of video-mediated communication studies, focusing on the effect of nonverbal cues on a video-mediated tutoring situation. We will first state communication theoretical underpinnings and then we will focus on the role of kinesic cues and ostensive-inferential cues in communication and mediated activities. After that we will describe our experimental method, explain in details the coding scheme we used to analyze the tutoring dialogue and the measures we collected. We will finally conclude with a discussion of our outcomes to highlight some convergences in regard to the previous literature and to the design of user interfaces in video-mediated tutoring environmen
