Un des objectifs des politiques éducatives européennes en matière de formation professionnelle des enseignants novices consiste à consolider les partenariats entre les universités et les établissements scolaires. Sur le plan scientifique, la majorité des études pointent l’importance de renforcer la collaboration entre les formateurs de ces deux institutions par des dispositifs fondés sur le modèle des « communautés de pratique » (Lave & Wenger, 1991). Or, ces études restent souvent peu précises sur la nature de leurs activités au sein de tels dispositifs. Cette recherche vise à analyser les activités de formation d’un collectif de formateurs et leurs conséquences sur la formation professionnelle d’un enseignant novice.Cette étude s’appuie sur une lecture de la formation professionnelle des enseignants novices (Bertone, 2011 ; Chaliès, 2012) qui emprunte certains postulats à une théorie générale de l’apprentissage (Nelson, 2008) et de l’action collective (Wittgenstein, 2004). Cette lecture est ordonnée par trois activités de formation : (i) enseigner des règles pour permettre aux enseignants novices de signifier leur vécu et agir différemment en classe ; (ii) aménager des situations et contrôler les premiers suivis des règles pour leur permettre d’en constater les résultats ; (iii) accompagner leur développement en les aidant à interpréter les règles apprises.Cette recherche a été menée en collaboration avec deux collectifs de formation en éducation physique et sportive. Composé chacun d’un enseignant novice et de plusieurs formateurs, ces collectifs ont été mis en place lors d’un dispositif de formation par les visites. Deux types de données ont été recueillies : des données d’enregistrement audio-vidéo (des leçons et des entretiens de conseil pédagogique menés en suivant) ; des données d’autoconfrontation. Les données ont été analysées afin d’identifier les règles apprises et/ou suivies par les acteurs pour signifier leurs activités au cours de chacun des temps du dispositif.Les résultats montrent principalement l’intérêt pour le collectif de formateurs : (i) de mener une activité d’enseignement (et éventuellement d’explication) ostensive pour permettre à l’enseignant novice de réaliser les premiers suivis des règles conformes à leurs attentes ; (ii) d’aménager les situations de classe pour faciliter son constat des résultats attendus des règles préalablement enseignées ; (iii) d’accompagner son développement en l’aidant à faire usage des règles apprises dans de nouvelles circonstances. / One of the aims of European education policies in terms of professional training of pre-service teachers consists inconsolidating partnerships between universities and schools. At the scientific level, most studies emphasize the importance of strengthening the collaboration between trainers in both institutions through training programs based on the model of the “communities of practice” (Lave & Wenger, 1991). However, those studies do not really specify the nature of the activities organized in such programs. This study aims at analyzing the training activities of a team of trainers and their consequences on the professional training of pre-service teachers. It leans on a way of reading professional training of pre-service teachers (Bertone, 2011 ; Chaliès, 2012) which borrows some premises from a more global theory about learning (Nelson, 2008) and collective action (Wittgenstein, 2004). This way of reading is structured around three training activities : (i) teaching rules to enable pre-service teachers to give meaning to their experience and behave differently in class ; (ii) adjusting situations and checking the first instances of rule-following to enable them to observe the expected results; (iii) working along with them by helping them to interpret the rules they have learnt.This study was conducted together with two training teams in Physical Education. Every team was made up of one pre-service teacher and several trainers. They were created during training visits. Two sorts of data were gathered : audio and video recordings (of the lessons and of post-lesson interviews that had followed) ; self-confrontation data. Those information were analyzed so as to identify the rules that had been learnt and / or followed by the actors in order to give meaning to their activities in every step of the program.Results mainly show the significance, for the team of trainers, in : (i) carrying out a ostensive teaching activity (together with, possibly, an explanation), to enable the pre-service teachers to check if the first instances of rule-following are respected as they had planned ; (ii) adjusting class situations to make it easier to observe the results expected from the rules he would have taught beforehand ; (iii) working along with them in their professional development by helping them to use these very rules to new circumstances.

Ce travail de thèse est centré sur les effets de la distraction sur les performances de conduite. Lorsqu'il conduit, un conducteur doit non seulement être capable de maintenir le contrôle du véhicule, mais également être en mesure de prélever et de traiter les informations pertinentes provenant de l'environnement routier. Ces capacités peuvent être mises à défaut par l'introduction des systèmes de communications et d'informations dans les véhicules qui le placent en situation d'attention partagée et augmentent les sources de distraction. Ce travail a tenté de déterminer comment la population des jeunes conducteurs novices, caractérisée par un fort taux d'accidents (Clarke et al. 2005) et des compétences de conduite faiblement développées (Whelan at al. 2004) gère ces situations d'attention partagée. Deux expérimentations ont alimentés cette thèse. La première, en environnement réel de conduite, visait à analyser les effets de l'utilisation conjointe d'un système de navigation et d'un téléphone portable sur la qualité de la prise d'information et du traitement de l'information (au travers de différents paramètres comportementaux). La seconde, réalisée en laboratoire, était destinée à compléter les résultats de la première expérimentation en se concentrant exclusivement sur les modalités de recherche et de prise d'informations selon que le conducteur soit novice ou expérimenté. En fonction de l'expérience de conduite, les résultats offrent des conclusions mitigées en matière de traitement de l'information en situations d'attention partagée.

How do experienced lenders make decisions? This dissertation addresses this question by investigating judgment and decision-making behavior of loan officers in banks as well as credit managers in supplying companies. The dissertation applies an integrated economic-psychological perspective and consists of seven parts: a comprehensive literature review and six separate empirical papers. Reviewed areas are research on judgment and decision-making (JDM), research on expert decision-makers, and earlier empirical work on experienced lenders. The six papers shed light on: (1) desirable personal attributes of expert credit analysts; (2) the use of software to track JDM behavior; (3) differences between novices' and experienced loan officers' JDM behavior; (4) the relationships between information acquisition, risk attitude, and experience; (5) attitudes towards credit decision support systems; and (6) attitudes towards requesting collateral. Employed methods were in-depth interviews, a nation-wide survey, and a computer-based experiment.On the whole, the empirical findings give an ambiguous picture of the alleged superiority of experienced lenders' judgment and decision-making behavior. On the one hand, experienced lenders seem to be capable, careful, and conscious of their responsibility. On the other hand, they tend to disagree and make contradictory judgments and decisions. The applied perspective and methodology are not only aimed at providing better insights into how experienced lenders make decisions, but can also stimulate future research on how professionals in other domains than credit granting make decisions. / Diss.

Digital fabrication technologies such as 3D printing is predicted to have a significant impact on our future society. However, the complexity of current 3D modelling softwares  risk deterring novices from engaging with the technology. In this thesis, a series of workshops were conducted to explore the implications for novices to create models out of tangible materials such as clay, paper and LEGO, that were then scanned and printed with a 3D printer. The results show that while the tangible materials create engaging opportunities for novices to engage with digital fabrication technologies such as 3D printing, the materials also provide limitations and constraints depending on their physical properties.

Le métier d’enseignant universitaire s’apprend le plus souvent sur le tas (Knight, Tait & Yorke, 2006). Mais que recouvre cet apprentissage sur le tas ? L’objectif de cette thèse est de déterminer les pratiques d’apprentissage au travers desquelles, en France, les enseignants universitaires débutants construisent leurs compétences d’enseignement. La recherche, menée auprès d'universitaires novices, questionne l'usage de huit modèles d’apprentissage susceptibles d’être à l’œuvre dans le processus de construction des compétences. La thèse montre que les pratiques des novices sont éclectiques et tendanciellement non-structurées. Alors que les pouvoirs publics considèrent la mise place d’une formation initiale formelle et systématique, cette recherche de thèse engage à une réflexion sur une formation pédagogique des universitaires qui prendrait en compte la diversité des pratiques et l'aspiration des novices à l'autonomie. / How to teach in academia is most often learnt on-the-job (Knight, Tait & Yorke, 2006). But what does the phrase “on-the-job learning” genuinely mean in this case? This doctoral dissertation aims to identify which learning practices novice academics make use of to construct their teaching competences in France. A survey was carried out amongst novice academics asking them to describe how eight learning models may have contributed to the process of constructing their teaching competences. Results show that novices’ practices are eclectic and mainly informal. While public authorities have been developing for a while formal training structures targeted at all newly-hired academics, this research suggests that the variety of practices and the aspiration of novices to informality should also be taken into account.

Social-comparative feedback (i.e., providing a learner with information regarding his/her performance relative to a group average) has been shown to influence a learner’s psychological and behavioural outcomes during motor skill acquisition (Avila, Chiviacowsky, Wulf, & Lewthwaite, 2012; Eliasz, 2012; Lewthwaite & Wulf, 2010; McKay, Lewthwaite, & Wulf, 2012; Stoate, Wulf, & Lewthwaite, 2012; Wulf, Chiviacowsky, & Cardozo, 2014; Wulf, Chiviacowsky, & Lewthwaite, 2010, 2012; Wulf & Lewthwaite, 2016). This research indicates that motor skill acquisition is facilitated when learners believe they are performing better than the average, regardless of their actual performance. It has been suggested (Wulf & Lewthwaite, 2016) that a better-than-average mindset enhances psychological factors such as self-efficacy and motivation and in turn, actual behaviour. However, there is also evidence to suggest that self-efficacy (having state-like properties) and motivation (having both state and trait-like properties) are related in terms of their affective influence on learning (Bandura, 1997; Schunk, 1990, 1991, 1995) but the relationship between the two constructs and its subsequent outcomes remain unclear. Even though individual differences in motivation have been suggested to influence self-efficacy beliefs, they have been largely ignored in this line of research. There is also evidence to suggest that learners possessing high levels of motivation (whether that may be at a trait or state level) may not interpret feedback in the same manner (Aronson, 1992; Festinger, 1957; Frey, 1986; Harmon-Jones, 2012; Harmon-Jones & Harmon-Jones, 2002; Harmon-Jones, Harmon-Jones, Fearn, Sigelman, & Johnson, 2008; Harmon-Jones & Mills, 1999; Harmon-Jones, Schmeichel, Inzlicht, & Harmon- Jones, 2011; Steele, 1988). Therefore, the goal of this dissertation is use both theoretical and applied perspectives to examine the degree to which social- comparative feedback affects psychological and behavioural outcomes in highly- motivated learners (e.g., medical trainees) learning procedural skills. Independent of actual performance, we provided manipulated feedback information to novice pre-clerkship medical trainees while they were learning motor skills to suggest that they were performing better or worse than the average. The first study used a basic sequential key-press learning task (Eliasz, 2012) and a basic suturing task to explore the role of social-comparative feedback in medical trainees and tested whether features of the task were important (i.e., basic laboratory task or technical skill task) during the interpretation of this feedback. The second study used the same experimental paradigm to extend our results to a relevant medical education context (i.e., medical trainees learning basic suturing techniques). The final study examined whether the credibility of the feedback provider (i.e., expert versus peer) played a role in how social-comparative feedback was being internalized by novice medical trainees. Our initial study demonstrated that, compared to those receiving positive or no social-comparative feedback, medical trainees receiving negative social- comparative feedback during motor skill acquisition had significant difficulties in learning both the laboratory and technical skill task. These findings suggested that compared to other learners, novice medical trainees (a subset of highly-motivated learners), responded differently to social-comparative feedback. The second study replicated this pattern and revealed that medical trainees receiving below-average feedback during technical skill acquisition experienced significant detriments to their performance, learning and self-efficacy. Our final study found that regardless of the feedback source (hypothetical expert versus another peer), the experience of receiving negative social-comparative feedback impacted self- reported psychological measures and the immediate performance of a basic surgical technique. This dissertation provides, to the best of our knowledge, the first demonstration that medical trainees, a subset of highly-motivated learners, interpret social-comparative feedback differently than other learners studied in the literature. More specifically, receiving positive social-comparative feedback did not facilitate the learning process as found in previous studies with non-medical learners, while the delivery of negative social-comparative feedback, irrespective of task or feedback provider, was psychologically and behaviourally detrimental to novice medical trainees learning motor skills. / Dissertation / Doctor of Philosophy (PhD) / This dissertation includes three original studies designed to examine the effects of social-comparative feedback during skill acquisition in highly- motivated learners (e.g., medical trainees). Regardless of actual task performance, novice medical trainees who were provided with feedback during the learning process indicating that they were performing worse than the group average, experienced significant detriments to their psychological and behavioural outcomes. This effect was present regardless of the task being learned (i.e., key- pressing or suturing) or who was delivering the feedback (i.e., a hypothetical ‘expert’ or ‘peer’). Receiving better-than-average feedback did not result in any additional psychological and behavioural benefits. Contrary to the research with non-medical students, where “you are above-average” social-comparative feedback facilitates learning and “you are below-average” social-comparative feedback is no different than a control condition, these studies suggest that the experience of receiving below-average feedback during the learning process can be detrimental for highly-motivated novice learners. These findings are important to consider in both the context of feedback delivery and remediation as they provide evidence that novice medical trainees, regardless of the task and feedback provider, experience difficulty in receiving information that they are performing relatively poorly compared to their peers.

While driving, a driver must be able to maintain the vehicle control and also to process the relevant information from the road environment. These abilities can be impaired by the introduction of information and communication systems inside the car which put the driver in dual-task situation and increase the sources of distraction. This work tries to determine how the population of young novice drivers, characterized by a high crash rate (Clarke et al. 2005) and by poorly developed driving skills (Whelan et al. 2004) manages these situations of time sharing.Two experimentations were conducted. The first one, on real road, aims at analyzing the effects of simultaneously use of a navigation system and a mobile phone on the information processing (achieve by analyzing behavior parameters). The second one, in laboratory, aims at completing the first results, by focusing on modalities of research and handling information according to the drivers’ experience (novice or experienced). According to the driving experience, results are ambivalent in terms of information processing during divided attention situations.

Community-based Open Source Software (OSS) projects are generally self-organized and dynamic, receiving contributions from volunteers spread across the globe. These communities survival, long-term success, and continuity demand a constant influx of newcomers. However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this thesis, our goal was to identify and understand the barriers newcomers face and provide appropriate strategies to lower these barriers. Toward this end, we conducted multiple studies, using multiple research methods. To identify the barriers, we used data collected from: semi-structured interviews with 35 developers from 13 different projects; 24 answers to an open questionnaire conducted with OSS developers; feedback from 9 graduate and undergraduate students after they tried to join OSS projects; and 20 primary studies gathered via a systematic literature review. The data was analyzed using Grounded Theory procedures: namely, open and axial coding. Subsequently, the analysis resulted in a preliminary conceptual model composed of 58 barriers grouped into six categories: cultural differences, newcomers characteristics, reception issues, newcomers orientation, technical hurdles, and documentation problems. Based on the conceptual model, we developed FLOSScoach, a portal to support newcomers making their first OSS project contribution. To assess the portal, we conducted a study with undergraduate students, relying on qualitative data from diaries, self-efficacy questionnaires, and the Technology Acceptance Model. By applying the model to a practical application and assessing it, we could evaluate and improve the barriers model, changing it according to improvements identified during the conception of the tool, as well as suggestions received from the study participants. The FLOSScoach study results indicate that the portal played an important role guiding newcomers and lowering barriers related to the orientation and contribution process, whereas it was inefficient in lowering technical barriers. We also found that the portal is useful, easy to use, and increased newcomers confidence to contribute. The main contributions of this thesis are: (i) empirical identification and modeling of barriers faced by OSS project newcomers; and (ii) a portal providing information to support OSS project newcomers. / Projetos de software livre baseados em comunidade são, geralmente, auto-organizados e dinâmicos, e recebem contribuições de voluntários espalhados por todo o globo. A sobrevivência dessas comunidades, o sucesso a longo prazo, e sua continuidade exigem a entrada constante de novatos. No entanto, os novatos enfrentam muitas barreiras ao tentarem fazer a sua primeira contribuição para um projeto de software livre, o que leva, em muitos casos, a desistências. Portanto, um grande desafio para projetos de software livre é proporcionar maneiras de apoiar os novatos durante a realização de sua primeira contribuição. Nesta tese, nosso objetivo foi identificar e compreender as barreiras que os novatos enfrentam e fornecer estratégias adequadas para reduzir essas barreiras. Para isso, realizamos diversos estudos, utilizando vários métodos de pesquisa. Para identificar as barreiras, foram utilizados dados coletados a partir de: entrevistas semiestruturadas com 36 desenvolvedores de 14 projetos diferentes; 24 respostas a um questionário aberto realizado com desenvolvedores de software livre; feedback de 9 estudantes depois de tentarem contribuir para projetos de software livre; e 20 estudos obtidos por meio de uma revisão sistemática da literatura. Os dados foram analisados utilizando-se procedimentos da Grounded Theory: codificação aberta e axial. Posteriormente, a análise resultou em um modelo conceitual preliminar composto por 58 barreiras agrupadas em seis categorias: diferenças culturais, características dos novatos, problemas de recepção, orientação dos novatos, obstáculos técnicos, e problemas de documentação. Com base no modelo conceitual, desenvolvemos o FLOSScoach, um portal para apoiar os novatos no curso de sua primeira contribuição a projetos de software livre. Para avaliar o portal, realizamos um estudo com alunos de graduação, utilizando dados qualitativos de diários, questionários de autoeficácia (self-efficacy), e o modelo de aceitação tecnológica (TAM, do inglês Technology Acceptance Model). Ao aplicar o modelo em uma aplicação prática e experimentá-lo, pudemos avaliar e melhorar o modelo de barreiras, adequando-o de acordo com as melhorias identificadas durante a concepção da ferramenta, bem como sugestões recebidas dos participantes do estudo. Os resultados do estudo indicam que o portal FLOSScoach desempenhou um papel importante no direcionamento dos novatos e na redução das barreiras relacionadas com o processo de orientação e contribuição, enquanto não foi muito eficiente na redução de barreiras técnicas. Evidenciamos ainda que o portal é útil, fácil de usar, e aumentou a confiança dos novatos. As principais contribuições desta tese são: (i) identificação empírica e modelagem de barreiras enfrentadas pelos novatos em projetos de software livre; e (ii) um portal de informação para apoiar os novatos em projetos de software livre.

Digital fabrication technologies such as 3D printers entail a radical change to the traditional consumer-producer paradigm. Combined with other recent developments, self-styled Makers design and fabricate sophisticated devices and interactive technologies that would otherwise never have existed. However, stopping the uninitiated novice from making use of this potential is complex CAD software, and a high barrier to entry. In this study a series of workshops explore the potential of combining traditional handicraft materials – such as clay, paper and fabric – with 3D scanning to enable novices to work with 3D printers. Based on the results a set of instruction were created detailing the process of making three types of practical objects, covering the entire process from the making and subsequent 3D scanning of a physical object, to the software clean-up and final 3D printing. The results suggest that whilst the explored method can enable novices to create 3D printable models, a certain mindset is required for the novice to do so effectively. / Innovation +
