Análisis de escenarios y protocolos para integración de repositorios digitales y sitios web institucionales

En este trabajo se analizan los protocolos de interoperabilidad OAI-PMH y OpenSearch, junto a a la API REST disponible en DSpace 7, desde el punto de vista de su utilidad a la hora de exponer recursos de repositorios digitales en sitios web institucionales. Se analiza el grado de adopción de cada protocolo, su facilidad de integración con CMS como Wordpress o Drupal, y el nivel de personalización soportado en las consultas y en las respuestas que generan. A partir de este análisis se evalúan distintos escenarios en los cuales es posible utilizar alguno de los protocolos, y se ejemplifica con URL y criterios de filtrado en los casos donde sea posible. La evaluación de estos escenarios sugiere que si bien OAI-PMH resulta adecuado para cosechas masivas, no parece una buena solución cuando se requieren pocos recursos, integrados en CMS, y con criterios de filtrado muy específicos. El protocolo OpenSearch permite una fácil integración con CMS, pero resulta muy limitado por la información que ofrece y la falta de estandarización. Finalmente, la API REST de DSpace 7 ofrece una buena alternativa a OpenSearch, pero su implementación es muy reciente y su integración con CMS más compleja.Servicio de Difusión de la Creación IntelectualCentro de Servicios en Gestión de la InformaciónIbero-American Science and Technology Education Consortiu

An Investigation Into The Accessibility Of Massive Open Online Courses (MOOCs)

Massive Open Online Courses (MOOCs) are an evolution of open online learning that enables people to study online and for little or no cost. MOOCs can provide learners with the flexibility to learn, opportunities for social learning, and the chance to gain new skills and knowledge. While MOOCs have the potential to also bring these benefits to disabled learners, there is little understanding of how accessibility is embedded in the creation of MOOCs. The goal of this research has been to understand the accessibility barriers in MOOCs and to develop processes to identify and address those barriers. In the extant literature, the expectations of disabled learners when they take up MOOCs are not discussed and studies on MOOCs that report demographic data of learners do not consider disabled learners. However, disabled learners can face difficulties in accessing MOOCs, and certain learning designs of MOOCs may affect their engagement, causing them to miss out on opportunities offered by MOOCs. Technologies and the learning design approaches for MOOCs need to be as accessible as possible, so that learners can use MOOCs in a range of contexts, including via assistive technologies. This research has investigated the current state of accessibility in MOOCs. It has involved the following: Interviews with 26 MOOC providers; including software developers, accessibility managers, inclusion designers, instructional designers, course editors and learning media developers; Comparative quantitative survey data involving disabled and non-disabled learners participating in 14 MOOCs; Interviews with 15 disabled learners which have captured their experiences; and An accessibility audit was devised and then used to evaluate MOOCs from 4 major platforms: FutureLearn, edX, Coursera and Canvas. This audit comprises 4 components: technical accessibility, user experience (UX), quality and learning design; 10 experts were involved in its design and validation. This research programme has yielded an understanding of how MOOC providers cater for disabled learners, the motivations of disabled learners when taking part in MOOCs, and how MOOCs should be designed to be accessible for disabled learners. A range of barriers to accessibility in MOOCs have been identified, and an accessibility audit for MOOCs has been proposed. An open online learning environment should take into account learners’ abilities, learning goals, where learning takes place, and the different devices learners use. The research outcomes will be beneficial to MOOC providers to support the accessible design of MOOCs, including the educational resources and the platforms where the MOOCs are hosted. The ultimate beneficiaries of this research project are MOOC learners because accessible MOOCs will help support their lifelong learning and provide re-skilling opportunities

Design model for integrating learning management systems and massive open online courses on a digital e-Learning platform: implications for Zimbabwean universities.

Doctoral Degree. University of KwaZulu-Natal, Durban.Available affordances for learning provide opportunities for advanced technology-enhanced teaching and learning. Digital learning environments can make relevant learning content available to students using existing infrastructure. This creates an environment which requires different learning management systems (LMS) to interact with, and exchange information. Increasing use of mobile devices, digital learning platforms, LMS, and massive open online courses (MOOCs), has necessitated integration design approaches. However, ignorance of resources offered and discouragement and frustrations arising from the economic situation in Zimbabwe regarding regulated access to electronic services make automation of teaching processes a great challenge. In this thesis, a design model for integrating LMS and MOOCs on a digital learning platform is proposed. From an e-learning point of view, the study contributes to the working of e-learning management systems through automation process of uploading content to LMS. From a computer science point of view, the study contributes to software engineering principles where it puts together three different platforms; LMS, MOOCs and digital learning platforms under one design. Methodologically, the study uses design science research (DSR) framework with software modelling language to address challenges in teaching and learning. This study describes how the Technology Adoption Model (TAM) and Task-Technology Fit (TTF) model can be used together with DSR in relation to design model evaluation. A software modeling language was used to create the logical designs, which were evaluated using experimental design approach. Software engineering experts and lecturers were invited to validate proposed logical designs. The key deliverables of the study include requirements specifications for the design model for integrated learning management systems, as well as the logical designs for the design model. The design model, as per requirements specification and the evaluation thereof, are based on TAM and TTF. The hybrid model proposed was further validated using structural equation modeling via the partial least squares and path modeling. In our views, the interventions of integration work would support decision making, which influences choices made by policy makers when taking decisions about higher education technological infrastructure
