Includes bibliographical references / Although learning management systems (LMSs) have been widely adopted by universities in developing countries, their potential to support students' learning has not been fully exploited due to several factors. Some of the factors limiting the more successful implementation of LMSs in developing country universities have been identified and reported in this study. Most importantly, LMS implementation in developing country universities is constrained by limited institutional ICT infrastructures, Internet bandwidth and electricity outages that affect the accessibility of LMS services by the students. The main research question addressed in this study is: How can we better use the available ICTs and ICT infrastructure in developing country universities to enhance the accessibility of the LMS services by students to better support the implementation of LMSs? The research question was addressed through surveys and experimentation. Two surveys were carried out, and the findings of these surveys were useful in: understanding the current state of practice in LMS implementation in developing country universities; defining the problem; understanding the students' LMS expectations and needs; and deciding the nature of the intervention to be implemented. Through the surveys, it was established that the majority of students in the surveyed universities possessed mobile phones, most of which being internet enabled phones. The study therefore explored the possibility of enabling and enhancing mobile access for LMS services so as to enhance students' LMS accessibility through their mobile phones. The design, development, implementation and evaluation of the intervention (the mobile LMS) were achieved through a user-centred development approach that included participatory design, prototyping and user experience evaluation. An impact evaluation of the mobile LMS intervention indicated that: mobile LMS interfaces can lead to students' increased access and use of the LMS through mobile phones; students prefer streamlined mobile LMS interfaces with fewer and block-based services; with streamlined mobile LMS interfaces, students are able to get the LMS services they need on their mobile phones without the need for desktop and laptop computers and without the need for the full desktop LMS interfaces. While the streamlined mobile LMS allows the students an opportunity to more satisfactorily access the LMS services through their mobile phones, it also takes away the pressure from the constrained institutional ICT infrastructure and facilities such as computer laboratories. The design and development process of the mobile LMS intervention highlighted that students' involvement leads to creation of more usable and useful mobile LMS interfaces and that most of the students' mobile LMS needs can be achieved through a cross-platform mobile Web application.

Philosophiae Doctor - PhD / Research has shown that collaborative eLearning can provide educational opportunities to groups of learners; both distance learners as well as traditional campus-based learners. It provides innovative educational methods in which learning can be constructed. The way collaborative eLearning is administered, managed, used and adopted can assist in providing information for future design and improvement of collaborative software. The objective of this research is to provide an insight into adoption and use of collaborative eLearning environments and to discover new determinants of usage. To examine the usage of an eLearning environment at the University of the Western Cape, a cross-sectional survey was conducted with Computer Science students. While this study is specific to this university, the underlying principles can be generalised to other organisational types. This study is quantitative and qualitative in nature as well as deductive and inductive. Three hundred and six valid questionnaires were analysed using quantitative methods. Soft Systems Methodology was used to manage the research process and to create conceptual models to explain the research problem and identify solutions. It was a cyclical process. Findings show that although the university’s eLearning platform is utilised, students seem to prefer free and open source platforms. They use social and collaborative applications such as WhatsApp, Telegram, Dropbox, Google Drive, Google Docs as well as email messages. Four types of technology affordances: communicative-affordance, document share-affordance, course resource-affordance, and integrity-affordance were identified as being relevant in their choice of application. Furthermore, culture—masculinity/femininity, individualism/collectivism, Uncertainty Avoidance, and Power Distance—also have an effect on the adoption of collaborative eLearning applications and software the students used for learning. Chi-Square analysis found that individualism/collectivism and Power Distance were both significant and related to the adoption and usage of collaborative eLearning. Gender was found not to be a determinant of how students view the use of collaborative eLearning software applications. Finally, it was also found that understanding use and user behaviour, could provide the theoretical guidance to inform collaborative eLearning design. The analysis and findings show that culture influences the adoption of collaborative eLearning while technology affordance plays a major role in the use of collaborative eLearning.

Indiana University-Purdue University Indianapolis (IUPUI) / Over the past decade, universities had a significant improvement in using online learning tools. A standard learning management system provides fundamental functionalities to satisfy the basic needs of its users. The new generation of learning management systems have introduced a novel system that provides social networking features. An unprecedented number of users use the social aspects of such platforms to create their profile, collaborate with other users, and find their desired career path. Nowadays there are many learning systems which provide learning materials, certificates, and course management systems. This allows us to utilize such information to help the students and the instructors in their academic life. The presented research work's primary goal is to focus on creating an intelligent personal assistant within the social learning systems. The proposed personal assistant has a human-like persona, learns about the users, and recommends useful and meaningful materials for them. The designed system offers a set of features for both institutions and members to achieve their goal within the learning system. It recommends jobs and friends for the users based on their profile. The proposed agent also prioritizes the messages and shows the most important message to the user. The developed software supports model-controller-view architecture and provides a set of RESTful APIs which allows the institutions to integrate the proposed intelligent agent with their learning system.

The purpose of this particular thesis, is the design and teaching of the " Application Development in a programming environment " course, by using the open education platform DIPLEK, which utilizes the ICT for the development and organization of educational material by teachers. The course mentioned before, is addressed to those students of the Third Grade of High School, who are orientated to the Technological field of computer Science and Services Cycle. The course aims at introducing to student the sense of planning and developing the appropriate way of thinking about algorithmic problem solving. The goal of this thesis is to create an exemplary instructive method of this Pan-Hellenic subject that will be a useful tool for students and a reference tool for teachers. For the realization of the course, the platform of open education DIPLEK will be used. It has been designed and implemented based on the current needs of both student and teacher, for easy access to educational material and can be adapted to their needs as well. Furthermore, its use requires no special computer knowledge due to the fact that it offers a friendly graphical user interface. The material covered by the course, is the one the third Grade candidates are invited to know well, since they enter for it during National exams (problem analysis, basic concepts of algorithms, data structures and algorithms, the programming language "Language" and sub programmes charter). To achieve this goal a range of activities covering the breadth of capabilities of the platform will be used. Activities which aim at analyzing the obscure points of theory, already answered drills and exercises or others which demand a solution with the view to student’s involvement in a personal experiment process and a variety of tests such as multiple choices ones.

Digital undervisning blev under covid-19 pandemin en viktig metod för att kunna upprätthålla lärande för utbildningsinstitutioner. Genom att använda sig av digitala plattformar och verktyg som exempelvis Learning Management Systems (LMS) och Videokonferens verktyg (VKV) kan studenter lära sig utan att fysiskt vara närvarande.  Den tidigare forskningen har tagit upp de sociala och fysiska problemen som kan uppstå vid ett oönskat miljöombyte. Vidare har det lyfts fram att individer har olika förutsättningar vid distansutbildning vilket kan påverka lärandet under hela utbildningen. Det lyfts även fram styrkor och svagheter med distansundervisning men inget som specifikt berör hur de digitala plattformarna har påverkat studenters motivation, koncentration och studieteknik under covid-19. Syftet med studien var att undersöka hur studenter vid Linneuniversitetet upplever att de har påverkats av den ofrivilliga distansundervisningen covid-19 medför och de digitala lärplattformar och verktyg som används. En kvalitativ ansats med semistrukturerade intervjuer har varit studiens metod vid datainsamling. Studien har förhållit sig till fem informanter som studerat på olika program inom Linneuniversitetet. För att analysera data följdes Creswells sex steg för dataanalys vilket resulterade i två huvudområden som inkluderade fyra teman och tre subteman. Studien kom fram till att studenter upplever att det finns möjligheter till sociala interaktioner med VKV. Flexibiliteten och möjligheten att vara platsoberoende är väldigt positivt för studenter. Studien har konstaterat att studenters koncentration, motivation och studieteknik har påverkats negativt sedan införandet av VKV föreläsningar. Vid användning av LMS så har upplevelsen varit att det finns en minimal påverkan på centrala faktorerna för lärande. / During the covid-19 pandemic, digital education became an important method for maintaining learning for educational institutions. By using digital platforms and tools such as Learning Management Systems (LMS) and Video Conferencing tools (VKV), students can learn without being physically present.  Previous research has addressed the social and physical problems that can arise in the event of an unwanted environmental change. Furthermore, it has been emphasized that individuals have different conditions for distance education, which can affect learning throughout the education. It also highlights the strengths and weaknesses of distance education, but nothing that specifically affects how the digital platforms have affected students' motivation, concentration and study techniques during covid-19.  The purpose of this study was to investigate how students at Linnaeus University feel that they have been affected by the involuntary distance education that covid-19 entails and the digital learning platforms and tools used. A qualitative approach with semi-structured interviews has been the study's method of data collection. The study involved five informants who studied in various programs within Linnaeus University. Creswell’s six steps for data analysis was chosen to analyze the data which resulted in two main areas that included four themes and three subthemes.   The study concluded that students feel that there are opportunities for social interactions with VKV. The flexibility and the opportunity to be site-independent is very positive for students. The study has found that students' concentration, motivation and study techniques have been negatively affected since the introduction of VKV lectures. When using LMS, the experience has been that there is a minimal impact on the key factors for learning.

Learning Management Systems (LMS) have become a common feature in contemporary Higher Education institutions worldwide. LMS literature shows that the level of interest and/or knowledge among academics towards the importance and usefulness of these systems, and the opportunities they can bring to the teaching process are key factors affecting the degree of use of LMS in HE. To date, most of these studies have taken place in the context of developed countries, and there is only limited research in other areas. In recent years, LMS have been adopted widely in Saudi Arabia’s Higher Education sector, however, there are no strong and detailed data regarding the subject in this context, which could impede future developments. On the other hand, academics were chosen as the main focus of this investigation because studies have revealed that they have the most vital role in promoting and enhancing the use of LMS. Therefore, this research investigates academics’ adoption and usage of LMS in Saudi Arabia’s universities; it aims to understand the adoption conditions and identify what factors truly affect the adoption process and to what level are the systems being used and why. The investigation was guided by Grounded Theory research principles. Initially, a review of the literature identified the nature of LMS along with the issues confronting academics when they are trying to use it to its full potential in supporting the delivery of their courses. Afterwards, questionnaires were employed to further explore the phenomenon in its examined context, i.e. Saudi higher education. The generated data and concepts were then used to guide the research process and to develop interview questions. The interviews were carried out at three Saudi universities with a range of stakeholders, which signified the primary data source in this investigation. Analysis revealed that LMS did not emerge as a well-established component of academics’ activities in Saudi universities despite the positive view respondents expressed towards it. Findings also explained why LMS was either considered a secondary method to support face-to-face teaching, or under-utilised in fully online courses. Furthermore, findings revealed the primary factors influencing academics’ level of use of LMS. Moreover, there were issues identified in relation to the academics’ development and training for LMS, which had a significant effect on the academics’ level of use of LMS. Findings were then integrated into a substantive theory and a theoretical model, which represents the research primary outcome. The theoretical outcomes offer abstract explanation of the phenomenon about adopting innovatory systems in Saudi universities, LMS in this instance. In conclusion, suggestions for improving the current provision of LMS in Saudi Universities are made. Overall, this study provided an insight into the environment surrounding the early adoption phases of LMS in Saudi universities, which offers a better understanding of the phenomenon. Subsequently, this will help enhance the adoption process in current contexts and assist in the better future utilisation of these systems in similar situations.

Cloud-based computing in higher education has the potential to impact institutions on a myriad of fronts, including technology governance, flexibility, financial, and intellectual property. As the demand for blended and online education increases, institutions are considering expedient approaches to implementing learning management systems (LMSs). Cloud-based e-learning models, such as personal learning environments and open learning networks, are reported to be among the next generation of LMSs. Saint Anselm College launched a cloud enhanced LMS, HawkLearn, to support several blended courses. HawkLearn was flexible, low-cost, low-maintenance, and targeted to digital natives, accustomed to using web 2.0 based tools and social media. Reporting utilized a case study approach, tracking HawkLearn's evolution from concept to reality. Results yielded data for higher education institutions, evaluating LMS strategies.

O presente trabalho consistiu na proposta, desenvolvimento e teste de um ambiente computacional hierárquico que vise facilitar a criação, organização e gerenciamento de cursos para serem disponibilizados via Internet, inserido nos projetos de Educação a Distância conduzidos pelo CDCC (Centro de Divulgação Científica e Cultural da USP- São Carlos), tendo como objetivo inicial o treinamento e reciclagem de professores da rede pública, nas disciplinas de física e ciências. O ambiente possui um sistema especialista para o tratamento das dúvidas dos usuários, o Sistema Gerenciador de Dúvidas Online (SGDO) que se tornou uma ferramenta autônoma e hoje faz parte do Plantão de Dúvidas Online do CDCC/USP. O SGDO utiliza o conceito de Education Intelligence, através do uso de data mining, possibilitando ao instrutor selecionar dados, analisar informações, identificar tendência e tomar decisões no decorrer de um curso a distância. A ferramenta WebCourse é um ambiente hierárquico baseado na Web consistindo de quatro módulos: WebCourse Instrutor, WebCourse Monitor, WebCourse Aluno e WebCourse Administrador. Cada módulo possui ferramentas específicas, desenvolvidas para as necessidades dos agentes participantes do ambiente (instrutores, monitores, alunos e administradores). O ambiente é dito hierárquico porque algumas de suas ferramentas somente podem ser usadas por certos módulos. Cada módulo está altamente conectado aos outros e todas as ferramentas são baseadas em templates HTML, usando a linguagem script Lite, do banco de dados mSQL, para a geração de arquivos HTML dinâmicos. Todo o sistema é gerenciado através de um banco de dados mSQL, localizado num servidor web, onde os dados são armazenados e recuperados sob demanda. / The present work consisted on the proposal, development and test of a hierarchical computational environment to facilitate the creation, organization and management of courses to be available over the Internet, inserted on the projects of Distance Education conducted by CDCC (Center for Scientifical and Cultural Dissemination at the University of São Paulo at São Carlos). Its initial objective was training public school teachers of Physics and Sciences. The environment has a specialist system for the treatment of online doubts called Online Doubt Managing System (ODMS), which became an autonomous tool inside the Online Doubt Helping Center at CDCC/USP. ODMS utilizes the concept of Education Intelligence through the use of data mining, making it possible for instructors to select data, analyze informations, identify trends and take decisions during a course carried via Web. WebCourse is a hierarchical web-based tool for the creation and management of web-based courses which consists of four modules: WebCourse Instrutor (Instructor Module), WebCourse Monitor (Teacher Assistant Module), WebCourse Aluno (Student Module) and WebCourse Administrador (Administrator Module). Every module has a set of specific tools, developed to meet the necessities of the environment\'s participant agents (instructors, teacher assistants, students and administrators). The tool is said to be hierarchical since some of its tools can only be used by certain modules. Each module is highly connected to the others and every tool is template-based, using the mSQL database\'s Lite scripting facility in order to generate HTML files on-the-fly. All the system is managed through a mSQL database, located on a web server, where data is stored and recovered on demand.
