A presente dissertação de mestrado teve como objeto de estudo a análise das compreensões dos alunos-professores em relação ao portfólio de aprendizagens e a síntese reflexiva no processo de aprendizagem do curso de Pedagogia a Distância da Universidade Federal do Rio Grande do Sul. A observação das produções escritas dos alunos-professores foi realizada a partir do conceito de tomada de consciência de Jean Piaget. A coleta de dados ocorreu através dos registros escritos dos alunos-professores na plataforma Moodle e organizados com o apoio dos softwares NVivo e CHIC. Dessa forma, foi possível realizar dois estudos, embasados nas observações dos dados. Através do NVivo, foram realizados levantamentos e interpretações das informações. No CHIC, foi possível interpretar as relações de similaridades e implicações entre significado, aprendizagem e dificuldades compreendidas pelos alunos-professores sobre o portfólio e a síntese. Como desfecho da análise, foi possível verificar que os alunos-professores compreendem o portfólio de aprendizagens como ferramenta de fundamental relevância para a escrita da síntese reflexiva e que a produção escrita dos instrumentos de aprendizagem é vista como meio de substancial interesse para a articulação entre a teoria proposta no curso e a prática em sala de aula. / This Master’s thesis had as study object the analysis of the students-teachers’ comprehension in relation to the learning portfolio and the reflexive synthesis in the learning process of the Pedagogy Distance course of the Federal University of Rio Grande do Sul. The observation of the students-teachers’ written productions was done from Jean Piaget’s concept of awareness. The data collection was done through the students-teachers’ written records on Moodle platform and organized with the support of softwares NVivo and CHIC. In this way, it was possible to perform two studies, based on the data observations. Through NVivo, surveys and interpretations of the information were done. With CHIC, it was possible to interpret the relations of similarities and implications among meaning, learning and difficulties understood by the students-teachers about the portfolio and the synthesis. As a result of the analysis, it was possible to verify that the students-teachers understand the learning portfolio as a tool of fundamental relevance for writing the reflexive synthesis and that the written production of the learning instruments is seen as a way of substantial interest for the articulation between the theory proposed in the course and the practice in classroom.

With the dynamic development of internet, various protocols and applications had been gradually matured on the network. The network has objective merits such as getting beyond the limits of time and space and change the tradition teaching model. Otherwise, the learning portfolios documented by on-line learning websites help teachers keep track of students¡¦ learning process. With the educational information, teachers would be more able to observe students¡¦ learning in real time and provide students with different decision rules under various time frames for teachers to understand both students¡¦ learning behaviors and process instantaneously. Nevertheless, technology mediated learning (TML) refers to an environment in which the learner interacts with learning materials, peers, and/or instructors that are mediated through advanced information technology. Recently, there have been increasing interests in investigating if TML can yield positive learning outcome. However, the rapid growth of information technology concerning analyzing the learning track is of various analytic approaches and thus is really complicated. The lack of one integrative analysis of all the possible use of the diverse analyzing frameworks prevents teachers from picking one most appropriate analyzing framework for their own teaching. Accordingly, this research compares and contrasts the most prevailing data analyzing technique¡Ðdata mining and the traditional statistical analysis approaches with the hope to allocate matching analyzing tools for various kinds of courses as well as to provide teachers with immediate decision rules as bases for predicting students¡¦ possible learning behaviors.

The purpose of this study is to analyze the functional requirement of web-based portfolio supporting system and to investigate the relationship between learning portfolio and personal knowledge management. First, this study surveys the literature to explore the architecture of web-based portfolio supporting system. Then, a prototyping system that adopts the system architecture is implemented and finally this study evaluates the system by using the questionnaire and observing learners¡¦ operating conditions. A total of 69 subjects are from Kaohsiung Hospitality College. The main findings show that web-based portfolio supporting system meets learners¡¦ need mostly and has a positive effect on learners¡¦ learning process. Most learners are not familiar with portfolio assessment, and therefore teachers must make learners to understand what is portfolio assessment. A few learners organize and manage their personal learning portfolio according to their learning need. Furthermore, most learners are not used to sharing their files and knowledge. However, teachers can encourage learners to interact by promoting their sharing will. Finally, based on the research findings, this study proposes following suggestions for the follow-up research. 1. Portfolio assessment must be put into practice as soon as possible. 2. Improving teachers¡¦ participation to promote learners¡¦ will of interaction and sharing. 3. Adding teaching assistants to reduce learners¡¦ loading to establish learning portfolio.

Klausuren und Tests sind Prüfungsformen, die geeignet sind, die fachliche Kompetenz von Studierenden zu bewerten. Dabei sind es gerade soziale, personelle und methodische Kompetenzen, über die zukünftigen Lehrerinnen und Lehrer im Unterrichtsalltag verfügen sollten. E-Portfolios scheinen das Potential zu haben, Prüfungen offener und im ganzheitlichen Sinne kompetenzorientierter zu gestalten. Vorliegende Arbeit thematisiert Mehrwerte sowie problematische Aspekte bei der Einführung von E-Portfolio-Arbeit in der akademischen Ausbildung von Lehrerinnen und Lehrern und formuliert Empfehlungen für die erfolgreiche Implementierung dieser Methode und der notwendigen Werkzeuge. Dazu wird untersucht, welchen Stellenwert Portfolios und E-Portfolios derzeit in der Lehrerausbildung an der Technischen Universität Dresden haben, welche Software speziell für die vorherrschenden Rahmenbedingungen geeignet ist und welche positiven und negativen Aspekte bei der didaktischen Konzeption eines Lernszenarios mit E-Portfolio als Lern- und Prüfungsform zu berücksichtigen sind.

Enseigner la communication orale implique pour les enseignants de tenir compte de différents paramètres pour que les élèves puissent réaliser des apprentissages solides et durables. À cet égard, nous pouvons identifier entre autres la prise en compte des distinctions entre l’oral et l’écrit, le stress généré par les situations de prise de parole ou la particularité liée au caractère volatil de l’oral. Bien que différents moyens et outils aient été proposés et validés pour permettre aux élèves de développer adéquatement cette compétence, il subsiste des défis liés, entre autres, à l’aspect métacognitif de l’apprentissage. Certes, les modèles didactiques accordent dans leur structure une place aux activités réflexives, mais comment peut-on accompagner adéquatement les élèves pour que ces activités leur permettent d’en tirer le plein potentiel ? Cette étude propose donc d’explorer l’utilisation d’un outil favorisant justement la mise en œuvre d’activités réflexives, soit le portfolio numérique d’apprentissage, d’en décrire et d’en analyser les apports au regard du développement de la compétence en production orale d’élèves de 3e secondaire en classe de français, langue d’enseignement. Pour atteindre cet objectif général de recherche, nous nous sommes appuyé sur un cadre théorique présentant d’abord des éléments généraux autour de l’enseignement-apprentissage de l’oral puis de l’utilisation du portfolio d’apprentissage au secondaire. Trois éléments complémentaires viennent compléter le cadre théorique : l’autoévaluation, l’engagement affectif et l’autorégulation des apprentissages. Pour répondre aux objectifs spécifiques de recherche découlant de ces concepts, une méthodologie qualitative et interprétative à caractère exploratoire a été élaborée et a inclus la participation de 77 élèves de 3e secondaire. Puisqu’il s’agit d’une thèse par articles, chaque objectif spécifique de recherche fait l’objet d’un article. Dans le premier article, nous décrivons et analysons l’apport du portfolio numérique d’apprentissage sur l’autoévaluation de la compétence en production orale d’élèves du secondaire. Nos résultats montrent que l’utilisation des outils réflexifs associés au portfolio, notamment grâce à la vidéo, permet une meilleure identification des forces et défis en production orale. Dans le second article, décrivons et analysons l’apport de cet outil sur l’engagement affectif des élèves. À la lumière des résultats obtenus, le portfolio d’apprentissage offre une plus-value en ce qui a trait à la diminution du stress des élèves par rapport à la réalisation des productions orales. Dans le dernier article, nous élargissons notre description et notre analyse des apports de l’outil à l’utilisation de stratégies d’autorégulation dans un contexte d’apprentissage de la production orale. Les données analysées montrent que certains processus d’autorégulation, tels que la planification stratégique et l’enregistrement de soi, bénéficient de la démarche associée à la réalisation d’un portfolio numérique d’apprentissage. En conclusion, une synthèse et une analyse de l’ensemble des résultats au regard de la littérature, et des recommandations sont proposées afin d’offrir des pistes d’action et de formation pour les acteurs du milieu scolaire, en particulier les enseignants de français au secondaire. / Teaching oral communication implies that teachers are aware of different parameters so that students can acquire solid and durable learning skills. In this regard, we can identify amongst other things, the taking into account of the distinctions between oral and written production and the stress induced by having to deliver speeches or by the volatile aspect of this form of communication. Although different methods and tools have been suggested and validated in order to allow students to adequately develop this competency, there remain associated challenges such as the metacognitive aspect of learning. Certainly, the didactic models offer in their structure a place for reflexive activities but how can we adequately accompany students so that these activities allow them to grasp their full potential? Therefore, this study proposes to explore the use of a tool that fosters precise implementation of reflexive activities, the digital learning portfolio, and to describe the contributions regarding the development of the oral production competency of Grade 9 students in the French Language of Instruction class. To attain this general research objective, we relied on a theoretical framework primarily presenting general elements regarding oral teaching and learning and secondly, the use of learning portfolios in high school. Three complementary elements complete this theoretical framework: self-evaluation, emotional commitment and self-regulated learning. To meet the specific research objectives arising from these concepts, a qualifying and interpretative method, exploratory in nature, has been developed that includes 77 Grade 9 students. Since this is a thesis of articles, every specific research objective is a subject of an article. In the first article, we have described the contribution of the digital learning portfolio on self-evaluation of high school students in the competency of oral production. Our results show that reflexive tools associated to the portfolio, especially thanks to video, allow for a better identification of strengths and weaknesses in oral production. In the second article, we have described the contribution of this tool on the emotional commitment of students. In light of obtained results, the learning portfolio offers an added value in terms of stress reduction associated with the development of oral production work. In the last article, we have expanded our description of contributions of tools in the use of strategies to self-regulate in the context of learning through oral production. The analyzed data illustrates that certain self-regulating processes, such as planning strategies and self-recording, benefit from the steps associated in the development of a digital learning portfolio. In conclusion, a synthesis and analysis of all the results regarding the literature and recommendations are proposed in order to offer courses of action and training for the professionals in a school environment, particularly French high school teachers.

This thesis is concerned with the development of novel numerical methods for solving nondifferentiable convex optimization problems in real Hilbert spaces and with the investigation of their asymptotic behavior. To this end, we are also making use of monotone operator theory as some of the provided algorithms are originally designed to solve monotone inclusion problems. After introducing basic notations and preliminary results in convex analysis, we derive two numerical methods based on different smoothing strategies for solving nondifferentiable convex optimization problems. The first approach, known as the double smoothing technique, solves the optimization problem with some given a priori accuracy by applying two regularizations to its conjugate dual problem. A special fast gradient method then solves the regularized dual problem such that an approximate primal solution can be reconstructed from it. The second approach affects the primal optimization problem directly by applying a single regularization to it and is capable of using variable smoothing parameters which lead to a more accurate approximation of the original problem as the iteration counter increases. We then derive and investigate different primal-dual methods in real Hilbert spaces. In general, one considerable advantage of primal-dual algorithms is that they are providing a complete splitting philosophy in that the resolvents, which arise in the iterative process, are only taken separately from each maximally monotone operator occurring in the problem description. We firstly analyze the forward-backward-forward algorithm of Combettes and Pesquet in terms of its convergence rate for the objective of a nondifferentiable convex optimization problem. Additionally, we propose accelerations of this method under the additional assumption that certain monotone operators occurring in the problem formulation are strongly monotone. Subsequently, we derive two Douglas–Rachford type primal-dual methods for solving monotone inclusion problems involving finite sums of linearly composed parallel sum type monotone operators. To prove their asymptotic convergence, we use a common product Hilbert space strategy by reformulating the corresponding inclusion problem reasonably such that the Douglas–Rachford algorithm can be applied to it. Finally, we propose two primal-dual algorithms relying on forward-backward and forward-backward-forward approaches for solving monotone inclusion problems involving parallel sums of linearly composed monotone operators. The last part of this thesis deals with different numerical experiments where we intend to compare our methods against algorithms from the literature. The problems which arise in this part are manifold and they reflect the importance of this field of research as convex optimization problems appear in lots of applications of interest.
