Nowadays, society makes use of new technologies as they appear. Due to this boom, the use of resources via web is increasing notably. In of training and education cases, companies such as universities are offering tele-learning platforms to complement and facilitate the learning process. Some of these called e-learning platforms can have explanatory videos as a resource for training. For the codification of these videos, we have to use parameters which provide a trade-off between the video sizes to be transmitted that optimize bandwidth and video and audio quality. This paper presents a subjective study of the video quality on transmission depending on the types of users’ network access to …
Teledu: Transmedia Learning Ecosystem for People at Risk of Exclusion
2021
The TELEDU tele-education ecosystem, integrated by software and hardware components, allows the use of Web resources through Interactive Digital TV (iDTV) without the need to be continuously connected. It works with any existing digital TV standard and is especially useful for users who do not have broadband, being a very effective solution in places where there is a digital divide. The user must have, at least, a cell phone with 3G connection and any of these three options: Digital Terrestrial TV (DTT), Satellite TV or Cable TV. The conception of TELEDU is based on the premise that the software will offer a friendly interaction. Based on this, an interoperable, open and scalable environmen…
Organizing Shared Digital Reading in Groups: Optimizing the Affordances of Text and Medium
2019
Children develop their language when they explore and talk about literary texts. In this study, we explore the design of shared digital reading as a basis for critical reflection on the reading situation in an institutional context with its given opportunities and limitations. We examine six videotaped readings of one specific picture book app, with a focus on the strategies used by teachers in early childhood education and care institutions to control children’s access to the medium and the types of verbal engagement (about the story and about the medium) that are generated by these different strategies. We use qualitative and quantitative analysis of video data. A qualitative categorizat…
Blended learning in master studies in Mathematical Information Technology — Impacts on attendance and learning outcomes
2011
Blended learning based on lecture videos and face-to-face teaching provides good opportunities for students for participation in education, regardless of time or place. This article examines the impacts of blended learning, as it has developed in connection with master studies in information technology, on participation in education and on learning outcomes. The solution is based on face-to-face teaching and the use of streaming lecture videos. According to the results, the use of lecture videos increases participation activeness, and the increase in participation has a positive impact on completion of courses. However, the use of lecture videos does not seem to have any clear-cut effect on…
