    A study on the effect of communication and monitoring tools in web-based tutoring

    ACTA Press, ISSN: 1206-212XInternational audienceAmong Web-based education activities, tutoring is considered to be very efficient. If many studies focus on learner's role, performance, and satisfaction, many questions remain about the effect of the media communication on tutor-student interaction. We report on a study comparing tutor-students' interactions on a practical work session. Students and tutor are connected via audio-only or audio-video links, with or without sharing visual information. Results show that tutors shift the contents of dialogue with students from procedural to contextual sentences, in order to the different media settings

    Seeing the face and observing the actions: the effects of nonverbal cues on mediated tutoring dialogue

    International audienceMediated communication technologies, conveying verbal and nonverbal cues, are more and more employed in learning activities. Nevertheless, their effects on teacher-student interaction have been not clearly stated yet. Through two experimental studies, we investigated on the effects of nonverbal communication cues (kinesic and ostensive-inferential) on synchronous mediated tutoring dialogue, in which a tutor and a student communicate through audio-video communication tools. The outcomes show that kinesic cues lead tutor to monitor more carefully learner's ongoing task and to encourage much more them, while ostensive-inferential cues improve learner' task performance and lead both tutor and student to focus better on tutoring speech act

    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

    Overview on digital education in France

    Get PDF
    After writing and printing, digital seems to become the third social revolution. Nowadays, an increasing competition settles between world powers in this area. According to international statistics, France is not among the holders of a Âżdigital societyÂż label. Trying to Âżcatch upÂż the delay, the country demonstrates a proactive policy in order to accelerate digital usage in both society and school. Equipment of schools, continuing training for teachers or attractive digital activities for students, are just some measures in this direction. Initiatives proposed for the future are ambitious: create a ÂżDigital FranceÂż label, change the image of the digital jobs and develop a data security and privacy policy. However, the major challenges of the education system will be media education and actions to mitigate the risks of Internet use.ArtĂ­culo revisado por pare

    Les effets des indices non-verbaux sur les activités de communication à distance. Deux études expérimentale sur le dialogue tutoriel

    No full text
    We studied the effect of non-verbal cues on a video-mediated tutoring dialogue. Firstly, we presented theoretical underpinnings based on H.H. Clark's communication theory and we reviewed experimentations of the role of kinesic cues (facial expressions, body gestures) and ostensive-inferential cues (actions, deictic gestures). Next, we described the coding scheme we had used to analyze the tutoring dialogue during a procedural task and we presented two experimental studies: the aim of the first study was to evaluate the effects of kinetic cues on verbal dependant variables (the tutor's proactive behaviour, the tutor-student's mutual understanding and the intrinsic tutoring speech acts), performance (student's learning score) and subjective impressions (perceived quality of the dialogue). In the second study we evaluated the effects of ostensive-inferential cues on the same dependant variables. The outcomes of study 1 show that the tutor's behaviour is more proactive when kinesic cues are available, whereas study 2 shows that ostensive-inferential cues let the tutor and the student focus on intrinsic learning contents, improving mutual understanding and student's performance.Notre travail s'insÚre dans le domaine de la communication audio-vidéo médiatisée. Les recherches de ce domaine ont l'objectif de comprendre l'impact des technologies de la communication sur les différentes activités de communication et de réaliser des dispositifs adéquats pour ces activités. Quelle que soit la situation de communication, l'interface n'est plus un simple objet d'adressage et de traduction pratique des commandes de l'opérateur, comme dans la vision classique de l'interaction homme-machine, mais devient plutÎt un espace de communication interpersonnelleL'action de communiquer avec autrui ne se limite ni à une simple adéquation de codes verbaux et non-verbaux, ni à un processus de production d'inférences et d'interprétation d'indices contextuels. Les interlocuteurs agissent selon une logique coopérative (Clark, 1996) : cela signifie que les interlocuteurs doivent réciproquement accepter chacune de leurs contributions pendant un échange, afin de pouvoir partager des connaissances ou des faits relatifs à leur activité. Une communication réussie demande que les interlocuteurs co-construisent mutuellement leurs référentiels, s'appuyant sur les indices verbaux et non-verbaux. Parmi ces derniers, on se doit de distinguer les indices non-verbaux kinésiques (e.g., les expressions faciales, les regards, les gestes du corps, etc.) et les indices non-verbaux ostensifs-inférentiels (e.g. les gestes déictiques, les actions physiques). Nous avançons deux hypothÚses de travail principales : A) les indices non-verbaux kinésiques facilitent surtout le processus de communication et favorisent un sentiment de proximité sociale entre les partenaires distants ; B) les indices non-verbaux ostensif-inférentiels facilitent surtout l'intercompréhension et la réalisation de la tùche commune.Pour vérifier ces hypothÚses, nous avons construit une tùche expérimentale dans laquelle un tuteur se doit d'assister deux apprenants distants impliqués dans la réalisation d'un travail pratique (la réalisation d'une page en notation html) et qui ne peuvent pas communiquer entre eux. Dans la premiÚre expérimentation (n tutor=12, N étudiants = 48), nous étudions les effets des indices kinésiques, véhiculés par l'image-vidéo montrant les partenaires distants. Les résultats indiquent que les indices kinésiques facilitent le processus de compréhension mutuelle et l'activité de suivi du tuteur, sans pour autant améliorer la qualité du travail des apprenants. Dans la deuxiÚme expérimentation (n tutors = 12, étudiants = 72), nous nous intéressons aux indices ostensifs-inférentiels, véhiculés par l'image-vidéo relative aux actions effectuées par les partenaires distants sur les objets appartenant à leur espace de travail. Les indices ostensifs-inférentiels favorisent la construction des référentiels communs, facilitent le suivi du tuteur et induisent une amélioration du travail des apprenants. Nous discutons les résultats de deux expérimentations et nous avançons des propositions pour la conception des dispositifs consacrés à la communication tutorielle

    A methodological proposal to design a trace-based system to qualify cognitive features inscribed in digital learning resources

    International audienceTo reuse existing digital learning resources, a teacher has to perform a complex and creative in order to adapt them to the students' needs and fit their cognitive abilities. Nevertheless, metadata do not generally describe the cognitive facets of a digital learning resource. We give here a partial account of a trace-based system in its current state of development to index digital learning resources according to the metadata describing their "cognitive features". By "cognitive feature" we mean the cognitive activities (e.g., reading, listening, body interactions, etc.) associated with different message formats (e.g., text, audio, interactive animations, etc.)
