Les Technologies de l’Information et de la Communication (TIC) font désormais partie du paysage de nombreux établissements d’enseignement supérieur, secondaire et même primaire en Afrique. Les avantages pour l’Institution, l’enseignant et l’apprenant sont avérés (Mvoto Meyong, 2010). Cependant les expériences, à l’échelle des établissements de formation, sont encore peu nombreuses et peu concluantes. Cette thèse porte sur l’intégration des TIC dans un cours de français pour anglophones à l’université de Buéa au Cameroun. Le cours traditionnel, dans sa version uniquement présentiel en classe, se déroule dans un contexte limitant fortement la satisfaction d’objectifs pédagogiques essentiels. En effet, les effectifs pléthoriques, le peu de temps alloué à la formation, l’hétérogénéité des groupes d’apprenants font que les compétences de production ainsi que les compétences en interaction des intéressés ne peuvent être développées. En réponse à cet existant, cette thèse, de type recherche-action, présente un dispositif hybride articulant travail en classe et dans le centre technologique de l’université. Là sont offertes des activités de communication en petits groupes dans une modalité quasi-synchrone. Cette modalité, peu souvent étudiée dans la littérature de recherche, offre une alternative réaliste aux environnements synchrones peu fiables, compte tenu de l’état des réseaux et de l’Internet dans cette partie du monde. Afin d’étudier si ce nouveau dispositif de formation permet de dépasser les difficultés évoquées et de faciliter l’apprentissage, je l’ai déployé deux années successives, en l’entourant d’un protocole de recherche. Les données recueillies m’ont permis d’analyser les interactions, de mettre en évidence les traces d’apprentissage. Mais cette double expérimentation apporte aussi un nouvel éclairage au travers de l’analyse des obstacles qui ont handicapé la mise en œuvre du dispositif technopédagogique. Je questionne le modèle d’intégration des TIC qui traditionnellement concentre toutes les ressources en un seul endroit, sans tenir compte des contextes technologiquement limités. J’esquisse une voie alternative destinée, grâce à l’apprentissage mobile, à intégrer les TIC dans des dispositifs de formation de langues et un contexte technologique proches de notre situation prototypique. / Information and Communication Technologies are now part of the life of many institutions of higher education, secondary education and even primary education. The benefits for these institutions, as well as for teachers and learners are established. However, there are very few cases of experiments carried out in learning Institutions with positive results. This thesis is about integrating ICTs into a French course in the Anglo-Saxon university of Buea in Cameroon. The context in which the course is taught in classrooms makes it difficult for the objectives to be met. Because of the large class size, the little time allocated to the course and the heterogeneous nature of students’ language levels, speaking, writing and interactional skills are not worked out in class. This action research thesis sets out to propose a blended learning set-up that hinges around the university IT Centre. Online classes are articulated with classroom sessions. Thus, students have the opportunity to involve in small groups, in communicative activities and in quasi synchronous mode. These communication modality, very often less studied by CMC researchers, is an efficient alternative to synchronous communication and environments that are very much reliable as far as internet quality is concerned in that part of the world. The general question that has driven the research is: How can a technology instrumented approach help in overcoming difficulties and ease learning? To answer that question, two technology based experiences were carried out. They were guided by a research protocol. Data collected enable me to analyse interactions and determine traces of language acquisition. From the circumstances surrounding the experiments, it is discovered that there are a number of obstacles to the integration of ICT in “low tech context” like that which is studied. The technology-based stet-up pattern is then questioned. This research work goes further to propose mobile learning as an alternative to the ICT integration model that concentrates all the resources in a single location.

The aim is to understand how the Basic Informatics curriculum component can contribute to the promotion of citizen digital emancipation of rural youth, as to their personal and professional development. The subjects of the research are the students of the History-ITERRA course of the Universidade Federal da Fronteira Sul - UFFS, Campus Erechim. The research has an qualitative and quantitative approach. As a methodology for its development was used the cartographic method of research intervention proposed by Kastrup (2007), Passos, Kastrup and Escóssia (2009) and Passos, Kastrup and Tedesco (2014). As results obtained with this research are: the theoretical deepening on the reality of the students of the course of History-ITERRA of the UFFS; the development of the Culturas Híbridas course, from the gamification perspective, considering the blended learning, multimodal and ubiquitous culture; the proposed methodological design for the Culturas Híbridas course, which resulted in the development of Projetos de Aprendizagem Gamificados from the Games for Change perspective, making it possible to rethink the curricular component of Basic Informatics; the movement generated in the development of the PAG instigated the participants to identify issues within the GMF in relation to educational processes as well as to understand how technologies could contribute to this process. Thus, analog and hybrid games were developed that contributed to broaden the processes of citizen digital emancipation of the subjects of the field. In addition, the results point to the need to broaden the discussion about the curricular matrices, methodologies and practices developed in the UFFS courses.

Novice teachers do not have sufficient opportunities to troubleshoot real-world teaching situations prior to having their own classrooms. Antiquated professional development (PD) models lack the collaboration element that provides authentic application of concepts. This qualitative case study was conducted to fill a gap in research on novice teachers' voluntary participation in an online community of practice. The study explored how the situated learning in this virtual community addressed the cognitive and social needs of early career teachers as they made the theory to practice connections. The community of practice framework and the social learning theories supported socialization as essential in early career teachers' growth. Research questions in the study examined five teachers' beliefs about collaboration- in promoting community engagement, the influence of voluntary participation on the quality of teacher engagement, and teachers' perceptions of the use of Web 2.0 technology to build community. A priori codes were created using the theoretical frame and research questions to guide the analysis of audio, transcriptions, observations, and other coded artifacts to find themes and patterns promoting internal validity. Findings revealed teachers' belief in collaboration impacted their level of engagement virtually. While voluntary participation motivates teacher participation, it does not guarantee high quality engagement without accountability. Since attrition is a continual threat to the teaching workforce, study results validate recommending the use of virtual resources to facilitate CoPs to remedy the mentoring and coaching void for early career teachers. Also, innovative use of Web 2.0 tools should be used to expose new teachers to diverse experiences that bridge theory to practice gaps and encourage teacher leadership, which promotes retention.

In his keynote address to the National Council of Teachers of Mathematics research pre-session, Sloane (2006b) challenged mathematics education researchers to ‘quantify qualitative insights’. This quasi-experimental study used blended methods to investigate the development of two-digit addition and subtraction strategies. Concurrent classroom teaching experiments were conducted in two intact first grade classrooms (n = 41) in a mid-Atlantic American public school. From a pragmatic emergent perspective, design research (Gravemeijer & Cobb, 2006) was used to develop local instructional theory. An amplified theoretical framework for early base-ten strategies is explicated. Multilevel modelling for repeated measures was used to evaluate the differences in strategy usage between classes across occasions and the association of particular pedagogical practices with the emergence of incrementing and decrementing by ten (N10) or decomposition (1010) strategies (Beishuizen, Felix, & Beishuizen, 1990).The two matched classes were not different in terms of gender, poverty, race, pre-assessment performance, and special education services. After the first unit of instruction with differentiated pedagogical tools, the collection class was significantly (p = .001) more likely to use 1010 than the linear class. No difference was demonstrated during the post-assessment. Students in both classes were more likely to use N10 during the last structured interview than in the first (p < .0001). Furthermore, there was no difference between the two classes in using any advanced strategy; however, students in both classes were more likely to use an advanced strategy at the conclusion of the study than they were initially (p = .033). The order of emergence of 1010 and N10 was not associated with the ability to develop both strategies, but there was an association (p < .001) between use of an advanced strategy and success on a district-mandated written assessment of two-digit addition and subtraction.Two original instructional sequences of contextually-based investigations are presented. Protocols transcribed from videotaped lessons and dynamic assessment interviews are presented to illuminate specific constructs detected and to illustrate the pedagogical techniques. An amplified framework for early place value constructs is proposed. Recommendations for future studies, curricular changes, and the need of early intervention are discussed.

In well cementing, the cement slurry is exposed to the conditions far different than those of ordinary Portland cement (PC) used in construction. After placement, hardened cement paste should preserve integrity and provide zonal isolation through the life of the well. American Petroleum Institute (API) Class G cement is the most common cement type used in various well conditions. Class G cement has a high degree of sulfate resistance which makes it more stable than PC when subjected to the compulsive well conditions. Ground granulated blast furnace slag (GGBFS) blended cement has a long history of use in the construction industry, but is not extensively used in well cementing applications. This study presents an experimental program to investigate the applicability of CEM I and GGBFS blended cement pastes in the well cementing industry. Class G cement and blends of CEM I and GGBFS with the proportions (80:20), (60:40), (40:60) and (20:80) are prepared with same water/cement ratio (0.44) as restricted for Class G cement in API Specification 10A to be tested. The cement pastes are cured for ages of 1 day, 7 days and 28 days at 80

La tesi è finalizzata a indagare l’efficacia dell’imprenditoria sociale quale strumento di contrasto a situazioni di grave povertà e disagio sociale nei paesi in via di sviluppo. Particolare attenzione è rivolta alle principali sfide derivanti dal molteplice sforzo di promuovere lo sviluppo socio-economico locale, garantire la sostenibilità economica delle iniziative e - talvolta - tutelare l’ambiente naturale. La prima parte della tesi fornisce un framework teorico sull’imprenditoria sociale, con specifico riferimento ad alcuni aspetti critici della sua stessa essenza, alle sue potenzialità nella lotta alla povertà e ai caratteri distintivi del suo processo di implementazione. La seconda parte presenta due analisi empiriche sviluppate con il metodo dei casi e afferenti, rispettivamente, gli ambiti del non-profit e del for-profit. La prima esamina i processi di identificazione delle opportunità e di costruzione del business model, al fine di mettere in luce le divergenze esistenti tra le prospettive sociale, economica ed ambientale, e di comprendere come coniugarle; la seconda identifica alcune cruciali variabili - interne ed esterne - che incidono sul processo di implementazione ed implicano la necessità di conciliare finalità, approcci e strumenti tipici degli ambiti filantropico e imprenditoriale, ai fini di una efficace creazione di valore socio-economico. / The thesis aims at investigating social entrepreneurship attitude to truly act as a crucial tool in the fight against deep poverty and social disadvantages in developing countries, with a particular focus on the main challenges faced by social entrepreneurial organizations in their attempt to promote local social-economic development, while ensuring their own economic viability, and (sometimes) preserving global environment. The first part of the thesis provides a theoretical framework about social entrepreneurship landscape, with specific attention to some crucial aspects of its essence, its potentiality against poverty, and some distinctive features of its implementation process. The second part presents two empirically-based analyses carried out by using case-study method, respectively from the for-profit and the not-for-profit domains. The former investigates the processes of opportunity recognition and business model design, with the aim to highlight the divergences among social, economic, and environmental perspectives, and to understand how to combine them; the latter identifies some crucial - internal and external -variables affecting the implementation process and implying the need for a mix between charitable and business aims, approaches, and tools, for a successful blended value creation.

Szenarien mit Blended-Learning-Charakter sind Alltag an deutschen Hochschulen: Insbesondere durch die Verbreitung von Learning-Management- Systemen, in Sachsen namentlich „OPAL“, können Lehrveranstaltungen über die Präsenzveranstaltungen hinaus in nahezu allen Fachbereichen um computergestützte Lerneinheiten ergänzt werden. Nach der Etablierung von Web Based Trainings als typische digitale Ergänzungsmodule streben einige didaktische Konzepte die verstärkte Abstimmung von Präsenz- und Onlinephase an. In der jüngeren Zeit wurde vor allem die Idee des Flipped Classroom (auch Inverted Classroom genannt) diskutiert. Hierbei wird die traditionelle Aufteilung der Lehr-Lern-Aktivitäten, bei der die Wissensvermittlung in den Präsenzveranstaltungen und die Vertiefung des Gelernten in Übungen zu Hause stattfinden, vertauscht. Stattdessen erwerben die Studierenden das nötige Wissen online und im Vorfeld der Präsenzphase, in der dann mithilfe komplexer Beispiele und unter aktiver Einbeziehung der Studierenden das Verständnis gefestigt und durch den Lehrenden unterstützt angewendet werden kann. Auch die Großveranstaltung „Grundlagen der Wirtschaftsinformatik“ (GWI) an der TU Chemnitz soll im Übungsbetrieb durch ein Flipped-Classroom-Konzept verbessert werden. Hierfür werden bestehende Aufgaben mithilfe einer Fachlandkarte und der Bewertung der jeweiligen Lehrziele zu einem Online-Materialien-Pool aufgebaut. Die Präsenzphase soll zur stärkeren Einbeziehung der Studierenden in Form eines aktiven Plenums abgehalten werden.

The purpose of this study was to investigate the perceptions of students in an implementation of &ldquo / Learning by Design&rdquo / method through a web based learning environment. The information gathered from the students enrolled in the undergraduate course / &ldquo / Foundations of Distance Education&rdquo / in 2009 Summer School and 2009-2010 Fall Semesters was evaluated. The course was given in blended form, i.e. face to face lessons and online instructional activities were performed together. In the web based part of the course, several educational modules of an open source learning management system (LMS), such as quizzes, forums, lesson pages, wiki pages, mail interface etc. were used. The students were responsible for implementing an educational course site on the LMS platform, using the course curriculum applications. Within the scope of this thesis, the perceptions of the students about course-related projects, and online and classroom activities were investigated through interviews and questionnaires. The academic development of students was also considered in the study. Additionally, several informal interviews were also done with the instructor of the course in order to investigate his perceptions about the conduct of the course. Questionnaire results have been analyzed quantitatively and face to face interview results have been analyzed qualitatively. Both quantitative and qualitative data indicated that the students&rsquo / perceptions about how the course was conducted and the learning by design activities were generally positive. Especially the project work, which was assigned as a requisite of the learning by design method, was pointed out as a positive factor in students&#039 / learning of the subject matter both in the questionnaires and in the face to face interviews. Another important finding of the interview and questionnaire results was that the communication between the instructor and the students contributed positively to not only learning the course content but the quality of the projects as well. As an outcome of this study, many important factors, which lead to successful results in implementation of learning by design method in a web based environment, have been identified. These results are presented in detail in the &#039 / Discussion and Recommendations&#039 / section.

M. Tech. Business Informatics / Addresses the adoption of emerging technology through blended learning. In the study, the Department of Home Affairs has just adopted a new traveler processing system. To use this emerging technology, employees had to be trained, and blended learning was seen as an appropriate training style. The emerging technology, the new passport scanning readers, posed challenges that are unpacked in this mini-dissertation.

This thesis explores the use of an online robotics course, in the context of Technology Education, for senior secondary school students in an urban New Zealand (NZ) school. The reasons for using an online course are discussed through investigating the need for quality resources to assist schools in providing students with appropriate learning experiences, and knowledge to enable them to make informed choices with respect to technology careers. There is a shortage of students pursuing technology careers and that in turn influences the NZ economy (Baron & McLaren, 2006). The purpose of the study was to examine how an online robotics course can be used for teaching robotics and engaging students in a blended environment. The author planned, implemented, monitored and reviewed an online course in robotics through an action research approach using formative evaluation methods to determine the effectiveness of the individual action research cycles. After reflection at the end of each AR cycle, the online course was modified and updated to improve student engagement. Qualitative methods were used to analyse online discussions, classroom observations and discussions, and one to one interviews with the participants. Research findings identified four themes that influenced student engagement with the online robotics course: access to the online course, the students’ background knowledge and skills, the students’ interaction with the online course and the students’ conation or internal motivation. The research findings are discussed in terms of areas that need to be addressed when using an online course to teach robotics. These areas are the course design, student considerations and course implementation. Course design, or how the course is structured, includes opportunities for students to develop their thinking skills, experiences and activities for learning, and opportunities for conversation and interaction. Course design must also accommodate student considerations. Student considerations focus on the needs of the learners and their readiness to ensure successful engagement in the online course in terms of their background knowledge and skills in electronics and Web 2.0 tools, their conation and their key competencies. Course implementation includes the factors that need to be taken into account in the execution of the online course such as reliable access to the online course, the students’ interactions with the online course, and the learning culture of the school and classroom, and the role of the teacher. The thesis justifies the rational for using an online robotics course and describes how an online robotics course can address and advance student learning outcomes, how online tools can be used for assessment purposes, the aspects of course design that are successful for teaching robotics and online learning experiences that provide positive outcomes for students. Recommendations for teaching practice in terms of school-wide programmes to develop and support students’ digital literacy and key competencies, and teacher professional development in Technology Education and online robotics courses are provided. Suggestions for future research are given in terms of student conation, the development of critical thinking skills through forums and how teachers’ philosophies can be aligned to Technology Education and the intent of the NZ Curriculum.
