    ACTI-Cités consortiumInternational audienceBackground: Comprehensive assessment of sedentary behavior (SB) and physical activity (PA), including transport-related activities (TRA), is required to design innovative PA promotion strategies. There are few validated instruments that simultaneously assess the different components of human movement according to their context of practice (e.g. work, transport, leisure). We examined test-retest reliability and validity of the Sedentary, Transportation and Activity Questionnaire (STAQ), a newly developed questionnaire dedicated to assessing context-specific SB, TRA and PA. Methods: Ninety six subjects (51 women) kept a contextualized activity-logbook and wore a hip accelerometer (Actigraph GT3X + TM) for a 7-day or 14-day period, at the end of which they completed the STAQ. Activity-energy expenditure was measured in a subgroup of 45 subjects using the double labeled water (DLW) method. Test-retest reliability was assessed using intra-class-coefficients (ICC) in a subgroup of 32 subjects who filled the questionnaire twice one month apart. Accelerometry was annotated using the logbook to obtain total and context-specific objective estimates of SB. Spearman correlations, Bland-Altman plots and ICC were used to analyze validity with logbook, accelerometry and DLW data validity criteria. Results: Test-retest reliability was fair for total sitting time (ICC = 0.52), good to excellent for work sitting time (ICC = 0.71), transport-related walking (ICC = 0.61) and car use (ICC = 0.67), and leisure screen-related SB (ICC = 0.64-0.79), but poor for total sitting time during leisure and transport-related contexts. For validity, compared to accelerometry, significant correlations were found for STAQ estimates of total (r = 0.54) and context-specific sitting times with stronger correlations for work sitting time (r = 0.88), and screen times (TV/DVD viewing: r = 0.46; other screens: r = 0.42) than for transport (r = 0.35) or leisure-related sitting-times (r = 0.19). Compared to contextualized logbook, STAQ estimates of TRA was higher for car (r = 0.65) than for active transport (r = 0.41). The questionnaire generally overestimated work-and leisure-related SB and sitting times, while it underestimated total and transport-related sitting times.Conclusions : The STAQ showed acceptable reliability and a good ranking validity for assessment of context-specific SB and TRA. This instrument appears as a useful tool to study SB, TRA and PA in context in adults

    MasterNew technologies, thoroughly present in our daily life, have now gained access to the classrooms, often thanks to the social uses of the teachers themselves, but also thanks to massive local or national investments. The specific case of technology allowing asynchronous learning in the classroom, without any direct or simultaneous action from the teacher, brings questions about the efficiency of such devices and the possible impact on the teaching relationship.This research paper aims to contextualise this problematic to a specific school, first by taking special interest in defining and categorising the digital devices for asynchronous learning (DDAL), and secondly by seeking what could be the added value and limitations of such devices.The research methodology has been implemented within an holistic-inductive framework, and consisted in gathering and analysing data through a survey addressed to all the teaching staff of the school, and interviews conducted with teachers volunteers. The analysis of the survey’sdata has been conducted with usual statistics tools, and also using the methodology of qualitative thematic content analysis. The teachers’ interviews’ interpretation has been based on a multi-category analysis of the content.The results and their interpretation allowed to define more precisely the concept of DDAL and to propose a typology to categorise these devices according to three axis : the device’s modality, its linearity, and its metacognitive aspect. However, the added value of this technology in the classroom is more difficult to assess : even if a range of elements underline the contribution of these devices in regards of students motivation and differentiated instructions, the gain in pupils’ autonomy is not clearly demonstrated. We don’t think that the scale of this research -an only school, a limited number of teachers- allow to generalise these observations. But being able to define and sort these different pedagogical practices brings the question of the teaching relationship’s evolution in a context defined by deep changes in terms of ergonomic of digital devices, and by the increasing use of artificial intelligence.Les nouvelles technologies, ultra-prĂ©sentes dans notre quotidien, ont pĂ©nĂ©trĂ© dans les classes, souvent grĂące aux pratiques sociales des enseignants eux-mĂȘmes, mais aussi suite Ă  des investissements massifs au niveau local ou national. Le cas particulier des technologiespermettant des apprentissages asynchrones dans la classe, sans action directe et simultanĂ©e de l’enseignant, interroge sur la possibilitĂ© et l’éventuelle efficacitĂ© d’une dĂ©synchronisation des apprentissages, et l’impact possible sur la relation pĂ©dagogique.Ce mĂ©moire de recherche se propose de contextualiser cette problĂ©matique Ă  un Ă©tablissement scolaire en s’attachant d’une part, Ă  dĂ©finir et catĂ©goriser les dispositifs numĂ©riques d’apprentissage asynchrone (DNAA), et Ă  Ă©tablir dans un deuxiĂšme temps les plus-values etlimites de tels dispositifs.La mĂ©thodologie mise en Ɠuvre s’inscrit dans un cadre holistico-inductif et a consistĂ© Ă  recueillir et analyser des informations Ă  travers une enquĂȘte mise Ă  disposition de toute l’équipe enseignante de l’établissement, et des entretiens avec des enseignants volontaires.L’analyse des donnĂ©es issues de l’enquĂȘte a Ă©tĂ© conduite Ă  l’aide d’outils statistiques classiques, et Ă©galement selon la mĂ©thode de l’analyse de contenu thĂ©matique qualitative. La technique de l’analyse de contenu catĂ©gorielle fut mobilisĂ©e quant Ă  elle pour interprĂ©ter lesentretiens rĂ©alisĂ©s avec les enseignants.L’interprĂ©tation de ces rĂ©sultats a permis de dĂ©finir plus prĂ©cisĂ©ment le concept de DNAA et proposer une typologie afin de catĂ©goriser ces dispositifs en fonction de trois axes : la modalitĂ© du dispositif, sa linĂ©aritĂ©, et son aspect mĂ©ta-cognitif. Quant Ă  la plus-value de tellestechnologies, elle reste plus difficile Ă  Ă©tablir : mĂȘme si de nombreux Ă©lĂ©ments soulignent l’apport de ce dispositifs numĂ©riques en terme de motivation et de diffĂ©renciation pĂ©dagogique, le gain en autonomie n’est cependant pas clairement Ă©tabli. L’échelle de cette recherche -un seul Ă©tablissement, un nombre restreint d’enseignants- ne permet pas Ă  notre sens de gĂ©nĂ©raliser ces observations. NĂ©anmoins, la caractĂ©risation et lacatĂ©gorisation de ces usages pĂ©dagogiques du numĂ©rique posent la question de l’évolution de la relation pĂ©dagogique dans un contexte marquĂ© par une profonde mutation de l’ergonomie des appareils numĂ©riques et par la prĂ©sence toujours croissante de l’intelligence artificielle

    In a world where new technologies are increasingly present in our daily life, the device known as the augmented reality is gradually gaining ground as a rich and versatile interface. After being widely used in technical fields, the world of education is now ready to adapt this device to the learning environment. Several articles are detailing the research on the use of augmented reality in schools, especially regarding scientific learning, and integration of augmented reality in serious games. Digital books with their multimedia potential also reveal another outlet for augmented reality. Finally, consideration of augmented reality as an interface between the subject and the machine helps to understand the prerequisites in terms of ergonomics to adapt the use of this device in the school context. Despite some technical or sociological reservations, all indicators point to the potential of augmented reality in a learning environment thanks to its qualities of adaptability, contextualization, immediacy of feedback, and learners motivation.Dans un monde oĂč les nouvelles technologies sont toujours plus prĂ©sentes dans notre quotidien, le dispositif connu sous le terme de rĂ©alitĂ© augmentĂ©e s'impose peu Ă  peu comme une interface riche et polyvalente. AprĂšs avoir Ă©tĂ© largement utilisĂ© dans les domaines techniques, le monde de l'Ă©ducation s'est Ă  son tour emparĂ© du dispositif afin de l'adapter au contexte d'apprentissage. Plusieurs articles dĂ©taillent des recherches menĂ©es sur l'utilisation de la rĂ©alitĂ© augmentĂ©e dans le cadre scolaire, notamment en ce qui concerne des apprentissages scientifiques, et l'intĂ©gration de la rĂ©alitĂ© augmentĂ©e dans des dispositifs de type jeux sĂ©rieux. Le livre numĂ©rique et son potentiel multimĂ©dia se rĂ©vĂšle Ă©galement un autre dĂ©bouchĂ© pour la rĂ©alitĂ© augmentĂ©e. Enfin, la considĂ©ration de la rĂ©alitĂ© augmentĂ©e comme interface entre le sujet et la machine permet de mieux apprĂ©hender les prĂ©-requis en terme d'ergonomie pour adapter l'usage de ce dispositif au contexte scolaire. MalgrĂ© quelques rĂ©serves d'ordre technique ou sociologique, tous les indicateurs pointent vers les potentialitĂ©s de la rĂ©alitĂ© augmentĂ©e dans un contexte d'apprentissage grĂące Ă  ses qualitĂ©s d'adaptabilitĂ©, de contextualisation, d'immĂ©diatetĂ© des feedbacks, et de motivation des apprenants
