L’évaluation de la compétence professionnelle des futurs maitres du Québec à intégrer les technologies de l'information et des communications (TIC) : maitrise et usages

Au Québec, la compétence professionnelle à intégrer les technologies de l’information et de la communication (TIC) est une compétence professionnelle à acquérir par les étudiants en enseignement. Cependant, son acquisition est problématique à plusieurs niveaux. Afin d’évaluer et mieux comprendre la compétence, cette thèse présente trois objectifs : 1) décrire le degré de maitrise des TIC et leurs usages dans les salles de classe 2) identifier les facteurs qui influencent l’intégration des TIC en fonction de la compétence professionnelle, et finalement 3) décrire le niveau d’atteinte des composantes de la compétence. Pour atteindre les objectifs de l’étude, une méthodologie mixte fut employée. Ce sont 2065 futurs enseignants du Québec provenant de neuf universités québécoises qui ont complété le questionnaire en plus de 34 participants à des groupes de discussion (n = 5). Cette thèse rédigée sous forme d’articles, répondra à chacun des objectifs visés. Dans le but de mieux comprendre l’utilisation actuelle des TIC par les futurs maitres, le premier article fournira un aperçu de la maitrise d’outils technologiques susceptibles d’être utilisés lors des stages. Le deuxième article visera à identifier les variables externes ainsi que les différentes composantes de la compétence qui ont une influence sur l’intégration des TIC lors des stages. Dans le troisième article, afin de comprendre où se situent les forces et les faiblesses des futurs maitres quant à la compétence professionnelle à intégrer les TIC, une description du niveau d’atteinte de chacune des composantes sera réalisée afin d’en dégager une appréciation globale. Les principaux résultats montrent que pour la moitié des répondants, seuls cinq outils sur 12 sont intégrés en stage et ce sont principalement les outils peu complexes qui sont bien maitrisés. Le logiciel de présentation Power Point, est le plus fréquemment utilisé. Les données considérées dans le premier article suggèrent aussi l’importance d’augmenter, de façon générale, la maitrise technique des futurs enseignants. Les résultats du second article ont permis de constater que la « prévision d’activités faisant appel aux TIC » est une variable prédictive majeure pour l’intégration des TIC. L’analyse des résultats suggèrent le besoin d’enseigner aux futurs maitres comment développer le réflexe d’inclure les TIC dans leurs plans de leçons. De plus, l’appropriation de la sixième composante de la compétence joue un rôle important sur la probabilité d’intégrer les TIC. Les résultats du troisième article indiquent que les composantes 2, 4, 5 et 6 de la compétence sont partiellement maitrisées. La mieux maitrisée est la première composante. Finalement, la troisième composante de la compétence s’est avérée être encore non atteinte et reste à être développer par les futurs enseignants. Cette thèse nous apprend que des efforts considérables restent encore à accomplir quant à la maitrise de la compétence professionnelle à intégrer les TIC. Ces efforts doivent être accomplis à la fois par les futurs enseignants ainsi que par les universités au niveau de la structure des cours de TIC en formation initiale des maitres.

Eye tracking data representation and visualization : on information and communication studies at CETAC.MEDIA

Eye tracking has become a preponderant technique in the evaluation of user interaction and behaviour with study objects in defined contexts. Common eye tracking related data representation techniques offer valuable input regarding user interaction and eye gaze behaviour, namely through fixations and saccades measurement. However, these and other techniques may be insufficient for the representation of acquired data in specific studies, namely because of the complexity of the study object being analysed. This paper intends to contribute with a summary of data representation and information visualization techniques used in data analysis within different contexts (advertising, websites, television news and video games). Additionally, several methodological approaches are presented in this paper, which resulted from several studies developed and under development at CETAC.MEDIA - Communication Sciences and Technologies Research Centre. In the studies described, traditional data representation techniques were insufficient. As a result, new approaches were necessary and therefore, new forms of representing data, based on common techniques were developed with the objective of improving communication and information strategies. In each of these studies, a brief summary of the contribution to their respective area will be presented, as well as the data representation techniques used and some of the acquired results.

Codification vs personalisation: A study of the information evaluation practice between aerospace and construction industries

In the emerging digital economy, the management of information in aerospace and construction organisations is facing a particular challenge due to the ever-increasing volume of information and the extensive use of information and communication technologies (ICTs). This paper addresses the problems of information overload and the value of information in both industries by providing some cross-disciplinary insights. In particular it identifies major issues and challenges in the current information evaluation practice in these two industries. Interviews were conducted to get a spectrum of industrial perspectives (director/strategic, project management and ICT/document management) on these issues in particular to information storage and retrieval strategies and the contrasting approaches to knowledge and information management of personalisation and codification. Industry feedback was collected by a follow-up workshop to strengthen the findings of the research. An information-handling agenda is outlined for the development of a future Information Evaluation Methodology (IEM) which could facilitate the practice of the codification of high-value information in order to support through-life knowledge and information management (K&IM) practice.

Information sources, ICTs and price information in rural agricultural markets

The spread and rapid uptake of mobile telephony in Sub-Saharan Africa has highlighted the potential role of Information Communication Technologies in improving market participation and welfare outcomes for farm producers in agricultural produce markets. This article explores the influence of different sources of information and transmission technologies on the quantum and reliability of market information flowing to farm producers, based on a survey of farm households in northern Ghana. Our results suggest that the principal role of radio broadcasts and mobile telephony is in providing a broader knowledge of markets by enhancing the quantum of market information flowing to farm producers. They do not, however, appear to have a significant impact on the quality/reliability of price information obtained by farmers for making marketing decisions. Information sources appear to be the chief determinant of the reliability of price information, with price information obtained from extension agents being the most credible. Our results provide some useful insights for the design and implementation of Market Information Systems aimed at encouraging market participation by rural farm producers in agricultural markets.

Managing change in complex projects: configuration management, asset information and big data

As we enter an era of ‘big data’, asset information is becoming a deliverable of complex projects. Prior research suggests digital technologies enable rapid, flexible forms of project organizing. This research analyses practices of managing change in Airbus, CERN and Crossrail, through desk-based review, interviews, visits and a cross-case workshop. These organizations deliver complex projects, rely on digital technologies to manage large data-sets; and use configuration management, a systems engineering approach with mid-20th century origins, to establish and maintain integrity. In them, configuration management has become more, rather than less, important. Asset information is structured, with change managed through digital systems, using relatively hierarchical, asynchronous and sequential processes. The paper contributes by uncovering limits to flexibility in complex projects where integrity is important. Challenges of managing change are discussed, considering the evolving nature of configuration management; potential use of analytics on complex projects; and implications for research and practice.

Bullied by Budgets, Pushed by Patrons, Driven by Demand: Libraries and Tantalizing Technologies

Libraries are caught in the middle—between static or shrinking budgets on one hand and ever-expanding user needs on the other. How did we get here, and where do we go from here? This paper will offer two perspectives: Part I will present survey results about changing Library purchasing habits in light of changing formats, access, business models and user demands. Data from a previous survey on this topic will be compared and updated. Pricing trends and possible futures will be discussed. Part II will briefly trace the history of libraries’ roles in scholarly communication and connecting learners with knowledge. From there, we show an example of phasing in a patron-driven / demand-driven and short-term loan e-book program, complete with incorporating these tools in library instruction, research, and portable device loadability for field work.

The promised LAN: the transformative power of information and communications technology in developing countries

Este tese analise as implicações dos investimentos em tecnologia de informação e comunicação (ICT) em países ainda em desenvolvimento, especialmente em termos de educação, para estimular a implementação de uma infra-estrutura mais moderna em vez da continuação do uso de métodos tradicionais. Hoje, como o interesse e os investimentos em ICT estão crescendo rapidamente, os módulos e as idéias que existem para medir o estado de ICT são velhos e inexatos, e não podem ser aplicados às culturas de países em desenvolvimento. Políticos e investidores têm que considerar estes problemas quando estão pensando em investimentos ou socorros para programas em ICT no futuro, e investigadores e professores precisam entender os fatores importantes no desenvolvimento para os ICTs e a educação antes de começar estudos nestes países. Este tese conclue que investimentos em tecnologias móbeis e sem fios ajudarem organizações e governos ultrapassar a infra-estrutura tradicional, estreitando a divisão digital e dando o resulto de educação melhor, alfabetização maior, e soluções sustentáveis pelo desenvolvimento nas comunidades pobres no mundo de países em desenvolvimento.

A research agenda for malaria eradication: basic science and enabling technologies

Today's malaria control efforts are limited by our incomplete understanding of the biology of Plasmodium and of the complex relationships between human populations and the multiple species of mosquito and parasite. Research priorities include the development of in vitro culture systems for the complete life cycle of P. falciparum and P. vivax and the development of an appropriate liver culture system to study hepatic stages. In addition, genetic technologies for the manipulation of Plasmodium need to be improved, the entire parasite metabolome needs to be characterized to identify new druggable targets, and improved information systems for monitoring the changes in epidemiology, pathology, and host-parasite-vector interactions as a result of intensified control need to be established to bridge the gap between bench, preclinical, clinical, and population-based sciences.

Mutual Information and Perplexity based Clustering of Dialogue Information for Dynamic Adaptation of Language Models

We present two approaches to cluster dialogue-based information obtained by the speech understanding module and the dialogue manager of a spoken dialogue system. The purpose is to estimate a language model related to each cluster, and use them to dynamically modify the model of the speech recognizer at each dialogue turn. In the first approach we build the cluster tree using local decisions based on a Maximum Normalized Mutual Information criterion. In the second one we take global decisions, based on the optimization of the global perplexity of the combination of the cluster-related LMs. Our experiments show a relative reduction of the word error rate of 15.17%, which helps to improve the performance of the understanding and the dialogue manager modules.
