Applying Model-Driven Paradigm for the Improvement of Web Requirement Validation

This paper proposes an approach for Web requirements validation by applying the model-driven paradigm in classical requirements validation techniques. In particular, we present how the Navigational Development Techniques (NDT) approach exploits the model-driven paradigm to improve its requirements validation task by exploring tool cases that systematize or even automate the application of requirements validation techniques. Our solution is validated by applying it in a real industrial environment. The results and the learned lessons are presented accordingly

Present and future of Web content accessibility: An analysis

Web je stvoren kao univerzalna mreža znanja. Bio je to ogroman kvalitativni i kvantitativni skok u odnosu na pristup informacijama i njihovu obradu. Međutim, čak i danas, postoje znatne prepreke pristupu mreži velikog broja građana, uključujući osobe s invaliditetom i stare ljude smanjenih sposobnosti kao posljedice godina. Mogućnost pristupa je značajka kojom se olakšava pristup i uspješno korištenje web lokacije ili usluge što većem broju ljudi, bez obzira na njihova osobna ograničenja ili ograničenja nametnuta okolinom. Ovaj članak daje pregled osnovnih značajki mogućnosti pristupa mreži sada i u budućnosti, osvrćući se na uspješnu primjenu smjernica poznatih kao 2.0, kojima se osigurava podudaranje s postojećim zakonskim odredbama na nacionalnom i internacionalnom nivou.The Web was created as a universal network of knowledge. It represented a huge qualitative and quantitative leap in terms of acquisition and processing of information. However, even today, significant barriers make difficult the access of a large number of citizens to the web, including disabled users and old people with diminished skills as an effect of age. Accessibility is the feature which facilitates access to and successful usage of a web site or service for as many people as possible, regardless of their personal limitations or limitations imposed by their environment. This article reviews the main aspects of web accessibility and its future, passing through the effective implementation of guidelines known as 2.0, which ensure compliance with existing legislation at national and international level

Accessibility challenges in OER and MOOC: MLR analysis considering the pandemic years

The review of state of the art on creating and managing learning resources and accessible Open Educational Resources (OER) and Massive Open Online Courses (MOOC) is a topic that cannot only consider formal literature. The evidence and lack of a measurement consensus require the inclusion of contextual information, corroborating scientific results with practical experiences. For this reason, this article presents a review of accessibility models, OER and MOOC, considering the gray literature to capture experiences and trying to establish a shared understanding of the terminology commonly used in research on virtual accessibility and its impact on higher education. The bibliographic review relies on analyzing articles and scientific publications related to the topic following the Multivocal Literature Review (MLR) format. The results of this review establish that it is possible to apply accessibility review methodologies with transversal actions in the creation and management of learning resources and MOOCs. The research is related to one of the seventeen sustainable development goals defined by the United Nations to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all.This research work has been co-funded by the Erasmus+ Programme of the European Union, project EduTech (609785-EPP-1-2019-1-ES-EPPKA2-CBHE-JP).info:eu-repo/semantics/publishedVersio

Usability guidelines for mobile devices: length of hyperlinks

Abstract. The use of mobile devices is increasing in recent years, and their characteristics are different from those of computers (keyboard and screen size, interaction method, etc.), so it is important to specifically study the usability of these devices. This paper presents an experiment carried out with users to find the correct length (from the point of view of usability) of hyperlinks in mobile devices. A real mobile device has been used for the experiment, as well as more than 20 users. The experiment compared three different lengths of hyperlinks and it concluded that users prefer hyperlinks as short as possible and they are identified better when the text is not justified

New challenge for teachers: dealing with soft skills in multinational environments

Abstract: Globalization is not only influencing social and economics perspectives of Society. It is also a challenge for higher education teachers. In the case of IT degrees, well known curricula models and proposals as well as specific studies are diminishing uncertainty in the area of technical knowledge and skills. But success in multinational IT professional environments strongly depends on deployment of non technical abilities (the so called soft skills) which should be promoted among students to enable graduates reach best results. But which soft skills are most important in this type of environments? This paper presents results of a specific survey among experts and students intended to contribute to the determination of a recommended set of skills to be promoted by teachers in multinational teams of students
