Development of math anxiety and its longitudinal relationships with arithmetic achievement among primary school children
2019
Abstract The aim of this study is to examine the development of two separable aspects of math anxiety, anxiety about math-related situations and anxiety about failure in math, and their cross-lagged relationship with arithmetic achievement. The mean level of anxiety about math-related situations decreased among second, third, and fourth graders, and the level of anxiety about failure in math declined among third, fourth, and fifth graders. The rank-order of individuals was more stable in arithmetic achievement than in either aspect of math anxiety. Arithmetic achievement predicted later anxiety about failure in math, but neither aspect of math anxiety predicted later achievement. The result…
Warm experts for elderly users : who are they and what do they do?
2018
This paper examines “warm experts”—that is, nonprofessional persons who help inexperienced users come to terms with digital devices—and their significance for the use of digital media in everyday life by elderly Swedes. We analyze data from a national survey (N = 1264) and from qualitative, semistructured interviews with 18 elderly Swedes (aged 65+). Our data reveal that the warm expert usually is a closelyrelated person, often a child or grandchild, who is strongly involved in nearly every stage of technology domestication, from appropriation (i.e., identifying the need, buying the item, and installing and adjusting it) to incorporation (i.e., choosing and downloading suitable apps, teachi…
Early cognitive predictors of PISA reading in children with and without family risk for dyslexia
2018
Abstract This study examined language skills and pre-literacy skills (phonological awareness, rapid naming, and letter knowledge) before school-age as predictors of PISA reading at age 15 in two groups of children, with (n = 88) and without (n = 70) family-risk for dyslexia . Moreover, effects of family-risk on these early predictors, reading fluency , and PISA reading were examined while controlling the effect of gender. Children were followed from age 2 to 15. Family-risk had a significant effect on early language and pre-literacy skills, reading fluency and PISA reading. A similar model predicting PISA reading fitted the data well in the Family-risk and the No family-risk group. Languag…
A Comparison of Dyadic and Social Network Assessments of Peer Influence.
2021
The present study compares two methods for assessing peer influence: the longitudinal actor–partner interdependence model (L-APIM) and the longitudinal social network analysis (L-SNA) Model. The data were drawn from 1,995 (49% girls and 51% boys) third grade students ( Mage= 9.68 years). From this sample, L-APIM ( n = 206 indistinguishable dyads and n = 187 distinguishable dyads) and L-SNA ( n = 1,024 total network members) subsamples were created. Students completed peer nominations and objective assessments of mathematical reasoning in the spring of the third and fourth grades. Patterns of statistical significance differed across analyses. Stable distinguishable and indistinguishable L-AP…
The organizational use of online stock photos: The impact of representing senior citizens as eternally youthful
2018
The digital divide due to age is declining quickly. But this does not necessarily mean that the willingness to use stock photos depicting older people accompanying digital information is the same among all senior citizens. Three research questions are at the core of this paper: (1) To which extent can various senior citizens (women and men, younger old and older old, living alone or together, full of vitality or fragile) identify with online stock photos of older people accompanying information about pensions, income, health and housing?, (2) Which are the connotations of the visual signs used in such stock photos? and (3) What are the policy implications for organizations aiming at offerin…
Utilisation du numérique par les enseignants à l’université : description et analyse des facteurs explicatifs
2019
Dans cet article, nous nous intéressons à la nature des technologies de l’information et de la communication (TIC) mobilisées par les enseignants universitaires pour enseigner et aux facteurs explicatifs de cette utilisation. Nous procédons d’abord à un éclairage théorique notamment concernant les concepts de « TIC » et d’« utilisation ». Puis, à l’appui des données recueillies en mai 2016 auprès de 248 enseignants d’une université française, nous montrons que les TIC mobilisées par les enseignants à l’intérieur, mais aussi en dehors des heures de cours, sont plutôt d’ordre générique en opposition aux technologies plus sophistiquées. Les enseignants utilisent par ailleurs davantage les TIC …
Comment évaluer et mesurer la conflictualité liée aux usages de l'espace ? Eléments de méthode et de repérage
2010
Cet article a pour objet de présenter le travail réalisé depuis quelques années par une équipe pluridisciplinaire sur la question des conflits d’usage de l’espace et de révéler la méthodologie d’enquête et de collecte de données, ainsi que la structure de la base de données qui en est issue. Dans un premier temps nous procédons à une définition du champ des investigations, en donnant une définition de ces conflits, de leurs caractéristiques, des mobiles et des manifestations de la conflictualité, ainsi que des acteurs impliqués (I). Nous exposons ensuite notre méthode de repérage des conflits, fondée sur un diagnostic de zone et la mise en commun de différentes méthodes de recueil de donnée…
Navigating multiple logics: Legitimacy and the quest for societal impact in science
2022
Academic scientists are encouraged to pursue research that delivers both scientific and societal impact. This may involve a search for alternative mechanisms of social approval which lead to endorsement of scientists’ research goals. We explore how scientists mobilise and accumulate different forms of legitimacy, which might favour their participation in practices related to innovation and societal impact. We propose three specific sources of scientific legitimacy: i) scientists’ social networks (research-related legitimacy ties), ii) prominence in the relevant academic community (reputation-based legitimacy); and direct contact with the primary beneficiaries of the research (beneficiary-ba…
The Role of Information and Communication Technologies in the Relationship Between Group Effectiveness and Group Potency
2008
The aim of this research is to examine the role of information and communication technologies in the relationship between group effectiveness and group potency changes. A laboratory experiment compared 44 groups of four members, working in two communication media—face-to-face condition and computer-mediated communication (CMC). Groups developed a project during 4 weekly meetings during a 1-month period. No significant difference in group potency between communication media was found initially. However, different patterns of group potency development over time were identified. Group potency increased in the face-to-face condition, whereas it remained stable in the CMC condition. Results sho…
Posting for Consensus, Sharing Consensus. The Case of Migrants on Facebook, Ideological Views and Echo Chambers
2018
This study analyses posts and comments on a popular social network (Facebook) in order to investigate how web-users take advantage of participative platforms to post ideologically-driven comments, and how the exchanges create echo chambers. In particular, the study addresses populism expressed in online debates concerning migrants and used as a pretext to show group identities and ideologies. Facebook is thus taken as an example and considered a participatory platform (Boyd 2014) of political (populist) activism and the milieu for consensus-finding. The dialogic structure of comments is studied within Conversation Analysis adapted to online written texts (Antaki et al. 2005; Giles et al. 20…
