Professor of the University of the Basque Country - Euskal Herriko Unibertsitatea (Faculty of Education of Bilbao). Doctor in Telecommunications Engineer from the University of the Basque Country. Former member of the Department of Systems and Automation Engineering of the School of Engineering of Bilbao. Currently in the Department of Didactics and School Organization of the Faculty of Education. He has taught courses on programming, microprocessors, digital control, systems engineering and asynchronous tools for collaboration in education. His research activities include the areas of: a) PLE and PLN; b) Learning Analytics, Educational Data Mining and Social Network Analysis (SNA); c) Machine Learning.
The objective of this research is to measure the perception that teachers had about their own performance when they were forced to carry out Emergency Remote Teaching due to the COVID-19 pandemic. A questionnaire was provided to teachers of every educational stage in the Basque Country (Pre-school, Primary and Secondary Education, Professional Training, and Higher Education) obtaining a total of 4586 responses. The statistical analysis of the data shows that the greatest difficulties reported by educators are shortcomings in their training in digital skills, which has made them perceive a higher workload during the lockdown along with negative emotions. Another finding is the existing digital divide between teachers based on their gender, age, and type of school. A further worrying result is the lower technological competence at lower educational levels, which are the most vulnerable in remote teaching. These results invite us to reflect on the measures to be taken to improve equity, social justice, and the resilience of the educational system, which align with some of the Sustainable Development Goals.

This paper is in response, from an international perspective, to the manuscript entitled “Improving teacher professional development for online and blended learning: a systematic meta-aggregative review” (Philipsen, B., Tondeur, J., Pareja Roblin, N. et al. 2019). The impact of the manuscript has been reinforced by the claims of international organisations like UNESCO and ILO, as far as they highlight that Teacher Professional Development (TPD) for Online and Blended Learning are a priority in the present scenario. The findings can be clearly applied to guide appropriated TPD for the recovery as well as for a resilient education system. Nevertheless, the research was conducted in a West-European context where most learners use computers on an everyday basis, while half the world’s students do not have access to a household computer, and this has determined the emergency response to the pandemic. Dreesen et al. (2020) reported that most of the countries have adopted a remote education based on some combination of digital platforms, television, radio, take-home packages, home visits, text messaging and phone calls. It would be very interesting to incorporate these recent discoveries in the use of frugal technologies and elucidate if new components should be aggregated for TPD strategies from an international perspective. As far as the authors adopted the approach of a systematic meta-aggregative review, new data supported by unequivocal or credible evidence can be conveniently incorporated without reinterpreting the original findings.

Knowing whether Personal Learning Environments (PLEs) could transfer Web 2.0 affordances, which have been focused on the non-educational or recreational sphere, to the institutional sphere is important to move the research agenda beyond “cool uses” and to understand how the learning process is affected when students use this new type of environment in formal settings. This study analyzes the use of institutionally-powered PLEs (iPLEs) as a means to enable the participatory and community-centered model of Web 2.0 in higher education. Students from two undergraduate, inter-university, online courses were divided into two groups: a control group using a Virtual Learning Environment (VLE) based on Moodle, and an experimental group using an iPLE based on iGoogle, FriendFeed and Google Groups. The assumption that the iPLE is a suitable tool to create a cohesive and participative learning network that excels that generated by means of the VLE was explored. The results obtained through social network analysis performed to each environment’s forum data confirm this hypothesis.

Universities can offer eLearning 2.0 tools and services to learners while obtaining clear benefits from releasing the control over some learning content. This means a shift from the institution centred and monolithic model of traditional virtual learning environments (VLEs) to a more heterogeneous and open model. This article tries to plot an architecture to be put in practice by universities to give learners the control of their learning processes by using eLearning 2.0. We propose an institutionally powered personal learning environment (iPLE) that constitutes our vision of how Web 2.0 tools (blogs, wikis, starting pages), services (del.icio.us, Flickr, YouTube) and people arrangement and data sharing (social networking, learn-streaming) could be applied in an integrated manner to learning processes. First, this article justifies the suitability for a PLE in the context of eLearning 2.0 and European Higher Education Area. Second, an overview of the evolution from VLEs to PLEs is given, and different PLE approaches are reviewed. Third, the concept of an iPLE is presented, and a conceptual architecture for it is detailed. Finally, this article also describes the technological aspects of a prototype of iPLE Network designed for the University of the Basque Country, which will be used as a test-bed for a case study in the Faculty of Medicine.

This paper describes the design (hardware and software) and implementation of a modular communication system based on CAN network. The motivation of the work is related to the real-time distributed control systems field. The goal is to own the complete control of the communication stack when building embedded distributed prototypes. This would allow managing those communication issues that affect real time performance (i.e. computation of worst case execution times and priority assignment to tasks and messages). This CAN implementation (rtfCANopen) is modular, inexpensive, auto-downloadable and self-configurable. A case study, consisting in an autonomous mobile robot that uses rtfCANopen, is described. This prototype is designed and analysed using the Real-Time Framework developed by authors. This framework consists of a set of tools for developing real-time distributed systems and it covers all the phases: specification, analysis, simulation and code generation of distributed applications.

The development of Real Time Distributed Control Systems (RTDCS) is a very complex and multi-part issue where different specific tools are to be used. As these specialized tools are not designed to work together, it would be desirable to have a flexible tool framework where all the information were managed and stored following a predefined Model Driven Architecture. XML technologies and Web Applications (implemented as a component-based multi-tier application design defined by J2EE) have been selected to put into practice such a framework. It is proposed a model-based approach to develop software systems that require the collaboration of specific tools. This collaboration is achieved thanks to a Tool Collaboration Engine based on XML and Web Applications. A prototype of the framework was built for RTDCS, yet these concepts can easily be applied to any area of knowledge. The paper presents some conclusions on the integration of COTS.

Embedded systems are computer-based systems that often must have deterministic temporal behaviour. The application software must ensure overall system performance in terms of hard real-time constraints, reliability and safety requirements. Often application constraints include distribution of input/output. In some other cases, distribution is needed to achieve demanding performance or dependability requirements. This paper presents the design and implementation of the so-called Real Time Framework (RTF) that consists of a general environment for the easy generation of distributed control software. RTF covers from the specification of the distributed system to automatic code generation. The design is based on the integration of well-known commercial software for control systems into a framework that extends its use to distributed systems using a fieldbus as communication system. The internal design includes a model of the system in each design phase and information consistency is assured through an internal database.

The design of hard real time systems involves complex issues because requirements of time, performance and security must be met. Many authors have developed methods in order to assure delays are bounded in the system, but there is not so much work that assures bounding delays in distributed real time systems over industrial fieldbuses. This work tries to apply well-known theories and previous work in the field of real-time distributed systems using fieldbuses. In particular, the target fieldbus is CAN, although other fieldbuses are currently being studied. The first step was to get together previous studies. After that, we focused in defining a formal specification of a distributed system that included all the information relevant for the analysis of the temporal behaviour. A tool called BERTA (Basic Environment for Real Time Analysis) has been designed. BERTA processes the temporal model of the system, embodies deduced algorithms for schedulability analysis and performs simulation of the distributed system. BERTA is presented here in its very first version.

This work deals with the design of a real-time tool that implements a set of РID-type controllers using different algorithms and different structures. The tool not only performs the real-time control of a process but also performs on-line monitoring. It also offers an auto-tuning option that includes the evaluation of the dynamic characteristics of the process (via step response or a frequency domain model) and the computation of controller parameters using different methods. Once the auto-tuner has computed the PID parameters and these settings have been tested on the system, the auto-tuner sends the settings to the commercial РID.
