In recent years, remote laboratories have become integral to modern education, offering flexibility and accessibility compared to traditional, in-person labs. Integrating AI-powered assistance into remote labs has the potential to give them an edge by providing personalized learning experiences. This paper explores an innovative approach to promoting independent learning and critical thinking by embedding AI-driven support, using OpenAI's GPT-4 model, into a remote Field Programmable Gate Array (FPGA) laboratory. Through a web-based code editor, students write SystemVerilog programs and receive tailored assistance from the AI, while their designs are deployed on a Terasic DEl-SoC FPGA development board with real-time feedback via a live camera feed. The study, which involved students from an advanced digital design course interacting with the AI assistant, revealed strong engagement and positive feedback. Preliminary results indicate that AI-powered guidance can meaningfully boost student involvement, providing a scalable and effective framework for fostering active learning in engineering education.

In this Research-to-Practice paper, we detail the development and implementation of a 3D Digital Twinning simulator augmented with Virtual Reality (VR) capabilities, specifically designed for an embedded systems curriculum. With the rise in technology-enhanced learning tools, there has been a marked shift towards creating robust platforms that allow students to interact more deeply with their coursework. Digital Twinning and 3D virtual simulations have emerged as significant contributors to this shift. The challenge in most design-oriented courses lies in the integration of multiple tools and hardware components. Students often find themselves investing significant time in the setup and configuration of these components, time that could otherwise be devoted to the core learning objectives. Our 3D simulator was developed to alleviate this burden. It intends to offer a clear, intuitive visualization of tasks, allowing students to focus on designing and testing their implementations. This simulator does not just represent a theoretical concept but provides a realistic, interactive environment replicating real-world scenarios. One of the central case studies highlighted in this paper is the transition from a traditional FPGA-based digital design assignment-a car parking lot scenario with switches and breadboards-to an equivalent, but more immersive, 3D virtual simulation. This redesigned model boasts seamless interfacing capabilities with a remote FPGA lab, further bridging the gap between theoretical learning and practical application. To gauge the effectiveness and utility of our simulator, we conducted an anonymous survey among the participating students. The survey aimed to capture feedback on the usability, intuitiveness, and overall educational value of the Digital Twinning simulation. Preliminary findings from our study suggest a positive trend: Digital Twinning, combined with the immersive properties of VR, has the potential to significantly improve engagement, comprehension, and performance. This research underlines the evolving dynamics of education, where traditional methods are gradually being complemented, if not replaced, by technology-enhanced approaches. The results presented in this paper strongly suggest the potential benefits and adaptability of Digital Twinning in the contemporary educational landscape.

CAN bus is a very important communications protocol. Its usage is extended to many applications and it is key to know some fundamentals in an introductory course to industrial communications. A collaborative experience between the Public University of Navarra has permitted students of Industrial Technologies Engineering and Electrical and Electronic Engineering to access a remote laboratory where they can progress in the development of a project where they must implement a CAN bus client and server for monitoring the parameters of a vehicle. More than twenty parameters can be monitored and the remote laboratory is 24 hours a day accessible, which permits students to work at home and progress more in the multiprotocol project they develop at the university. The interface and some code examples are shown, along with some statistics that demonstrate the utilization of the tool by the students with the aid of some evaluation measurements taken by the lecturer. Finally, a survey was performed to the students in order to understand better the potential of the remote laboratory assisted teaching as well as to know where to improve it in the next future.

This Research to Practice Work-In-Progress paper presents a virtualized breadboard solution for FPGAs and ARM microcontrollers in remote laboratories. The circumstances that rose amidst the COVID-19 pandemic demonstrated the vulnerability of current engineering education practices, particularly in dealing with hardware resources. Pivoting to the emergency online instruction presented challenges to the traditional practices in delivering hands-on engineering labs, which necessitated a solution that handles hardware prototyping without compromising creativity and instruction. One vital aspect of the embedded systems learning experience is ensuring students and faculty members alike have opportunities to learn and build custom prototyping circuits that interact with microprocessors on breadboards. In this paper, we build on the prior work that our group implemented on using virtualization to interface a virtual breadboard with physical hardware through web applications. Our previous work was limited to interfacing with one particular kind of hardware, designed to explore the capabilities of fundamental transducers and actuators that interface with hardware I/O pins. In hardware engineering practice, however, designers are not constrained by a single microprocessor selection to control their system and designs and are not limited by the type of transducers and actuators that provide the external circuit functionality. This paper presents a solution by scaling the existing virtual breadboard research to support FPGAs and ARM microcontrollers and intermediate logic gate integrated circuits for practical use in engineering curriculums. Providing this increased selection of supporting hardware helps facilitate student learning and simulates hardware development in an industrial setting. Due to the rising popularity of FPGAs and ARM microcontrollers in industry and in education, we expect that our solution will serve a larger audience through this broader selection of supported hardware. Our solution virtualizes the breadboard prototyping experience without sacrificing the nature of real-time embedded systems by taking the user prototyped inputs and outputs and directly programming the functionality of the surrounding system to physical hardware. This balance between a virtualized interface and physical hardware implementation preserves a hardware curriculum embedded systems engineering education and brings a promising solution to expand the scalability and accessibility of engineering labs.

Social demands have promoted an educational approach based on an “anywhere and anytime” premise. Remote laboratories have emerged as the answer to the demands of technical educational areas for adapting themselves to this scenario. The result has not only benefit distance learning students but has provided new learning scenarios both for teachers and students as well as allowing a flexible approach to experimental topics. However, as any other solution for providing practical scenarios (hands-on labs, virtual labs or simulators), remote labs face several constraints inherited from the subsystems of its deployment -hardware (real instruments, equipment and scenario) and software (analog/digital conversions, communications, workbenches, etc.)-. This paper describes the Erasmus+ project Platform Integration of Laboratories based on the Architecture of visiR (PILAR) which deals with several units of the federation installed in different educational institutions and devoted to analog electronics and electrical circuits. Based on the limitations of remote labs, the need for the federation will be justified and its benefits will be described.

A remote laboratory is a hardware and software solution that enables students to interact with real equipment located somewhere else on the internet. This way, students interact with a real laboratory as if they were on a hands-on-lab session. Once the equipment is remote, it is also possible to share it among institutions, so students from one school or university can access a lab in another university. While there is an interest by many universities of sharing their laboratories, and there are several experiences doing so, the impact has been typically limited. One of the reasons for the limited impact is the lack of robustness in most solutions due to technical issues, which leads to a lack of trust and interest by the potential consumers. LabsLand is a spin-off of the WebLab-Deusto research group which sells access to laboratories of universities to other schools and universities. This contribution analyzes through use cases what are the technical and organizational pitfalls that were found in the process of taking real laboratories and making them available commercially and what are the solutions used to tackle the issues arisen.

Interactive live streaming is a key feature of applications and platforms in which the actions of the viewers affect the content of the stream. In those, a minimal capture-display delay is critical. Though recent technological advances have certainly made it possible to provide web-based interactive live-streaming, little research is available that compares the real-world performance of the different web-based schemes. In this paper we use educational remote laboratories as a case study. We analyze the restrictions that web-based interactive live-streaming applications have, such as a low delay. We also consider additional characteristics that are often sought in production systems, such as universality and deployability behind institutional firewalls. The paper describes and experimentally compares the most relevant approaches for the study. With the provided descriptions and real-world experimental results, researchers, designers and developers can: a) select among the interactive live-streaming approaches which are available for their real-world systems, b) decide which one is most appropriate for their purpose, and c) know what performance and results they can expect.

A remote laboratory is a software and hardware tool that enables students to access real equipment located somewhere else through the Internet. The laboratories are typically deployed in universities or research centers. A key factor of remote laboratories is that once they are available through the Internet their usage can be scaled up and used by students of other institutions. Thus, two or more institutions can share different equipment to reduce costs. Furthermore, this enables a sharing economy where multiple providers provide access to their laboratories to each other, freely or not. However, while the number of remote laboratory initiatives is high, the overall impact of these laboratories is fairly limited beyond the scope of the host institution or the scope (and duration) of projects in which the host institution is involved. The focus of this contribution is to outline a novel initiative addressing this scaling problem. After over 10 years working on the area our research group has started a spin-off focused on this topic, called LabsLand. A key factor of this spin-off is to provide a platform similar to other sharing economy marketplaces, aiming to provide features commonly ignored in the remote laboratories literature such as trust, accurate reliability or different pricing schemes for different scenarios.

Developing educational apps that cover a wide range of learning contexts and languages is a challenging task. In this paper, we introduce the AppComposer Web app to address this issue. The AppComposer aims at empowering teachers to easily translate and adapt existing apps that fit their educational contexts. Developers do not need to provide extensive translations and configurations of their apps and can simply follow certain guidelines to make their apps translatable and adaptable by the AppComposer. Since the AppComposer makes use of the standard internationalization specification used by OpenSocial, even external apps can be translated without contacting the original developer.

The lack of tracking and storing capabilities for the results of web-based learning activities is an issue that remains unsolved. Transitions or interactions defined by teachers through a set of conditions still require programming skills that stay far beyond the desired final results. In addition to this, authoring tools should be powerful enough to let lecturers generate contents which are high-quality, interactive, and tuned to each student's cognitive preferences and progress. Availability and processing capabilities, or motivation, relevance, etc., must also be aspects to address in this context. For these reasons, this paper aims to review the existing web application authoring toolkits focusing on distance education. In particular, we analize their main features, requirements and issues, as well as the most promising areas for future improvemenst in this field.

A remote laboratory is a software and hardware tool which enables students to use real equipment -located in an educational institution- through the Internet. This way, students can experiment as if they were using the laboratories with their own hands. And, depending on the design, instructors can later see the results of these students. During the last decade, federation protocols to share remote laboratories have emerged. The focus of these protocols is to be make remote laboratories of one institution available in other in an automated manner, through institutional contracts. And these federation protocols usually rely on existing Remote Laboratory Management Systems (RLMS), which usually provide APIs for tracking student usage. At the same time, the interest on Learning Analytics is increasing. Learning Analytics focuses on the measurement and analysis of data about learners in their context. In the particular context of federated remote laboratories, new challenges arise: on the one hand, remote laboratories must be prepared to track insightful information from the student session so as to extract patterns, and on the other hand, the usage of a federated environment requires different degrees of anonymity. This contribution describes the new Learning Analytics dashboard of WebLab-Deusto, detailing what information can be extracted and how the usage of a RLMS simplifies the development of such tools in a federated environment.

Educational remote laboratories are software and hardware tools that allow students to remotely access real equipment located in universities as if they were in a hands-on-lab session. Federations of these remote laboratories have existed for years, focused on allowing two universities to share their equipment. Additionally, the integration of remote laboratories in Learning Tools-LT-(Learning Management Systems, Content Management Systems or Personal Learning Environments) has been achieved in the past in order to integrate remote laboratories as part of the learning curricula, being part of the practice exercises or even as a tool of evaluation. An cross-institutional initiative called gateway4labs has been created to perform this integration through federation protocols. In this contribution, this initiative adds support for OpenSocial as a new protocol for Learning Tools (in particular, for EPFL Graasp), as well as for the iLab Shared Architecture (in addition to WebLab-Deusto and UNR FCEIA laboratories already supported). Supporting OpenSocial opens a number of new technical and organizational challenges since public labs should be supported without registering students, teachers or schools. The focus of this contribution is to show these challenges and how they are tackled in the proposed open source implementation.

In this paper we present an automatic assessment model for competences developed in a physics course using VISIR remote experiment, based on a rubric and using learning analytics techniques to process data automatically collected from students' activity using Weblab-Deusto platform.

Nowadays, a large number of online laboratories are available and deployed throughout the world. Most of them are sponsored by universities and often only used by their home institution, because they tend to be dedicated to the needs of their creators. However, in many cases these labs provide successful experiences and other teachers would wish to incorporate them into their classroom activities and to embrace Learning-by-Experience methodologies. Currently, they cannot do that effectively without first tailoring the lab experience to their own teaching style and the educational background of their students. This can be a complicated affair, due the closed nature of many online labs and the steep learning curve of the few tools that allow customization. This paper describes the work on an application builder, named App Composer, which aims to make it easy for school teachers to create their own customized applications from existing ones. Different customization levels are provided, each one powered by a different type of composer. For instance, teachers will be able to easily translate an application into a new language, or to start with a template and create a customized version of an application. The App Composer makes use of Graasp and Open Social - a widely-used, interoperable and open technology.

A remote laboratory is a software and hardware tool which enables students to use real equipment -located in an educational institution- through the Internet. This way, students can experiment as if they were using the laboratories with their own hands. There are usually two approaches when designing remote laboratories: relying on small, inexpensive devices that can be deployed anywhere or relying software rich software infrastructures that support high load of users, providing panel administration, access to other institutional servers (e.g. directories such as Lightweight Directory Access Protocol “LDAP”), etc. With distributed remote laboratory architectures, it is possible to have the laboratory server on the former approach, but the management usually relies on the latter. In certain entities, such as secondary schools or farm schools, they may not be willing to buy and maintain a dedicated server for remote laboratories, and therefore the former approach is more adequate. However, a tradeoff is being made between management capabilities and how easy is to deploy the system. This contribution shows how federation could help in solving this tradeoff, and it uses a real fish tank remote laboratory as a case study.

A vast number of learning content and tools can be found over Internet. Currently, most of them are ad-hoc solutions which are developed for a particular learning platform or environment. New concepts, such as Widgets, Smart devices, Internet of Thing and learning Clouds, are ideas whose goals is the creation of shareable online learning scenarios over different devices and environments.

An educational remote laboratory is a software and hardware tool that allows students to remotely access real equipment located in universities or educational centers. Federations of remote laboratories have existed for years: students of one university transparently access laboratories of other university through software systems that enable these contracts. However, traditionally these contracts have been defined in a “one to one” basis and both universities using the same remote laboratory management system. The focus of this contribution is to present different interoperable bridges among different remote laboratory systems and explore how they can be chained to build complex ecosystems of remote laboratories. The impact of this chaining is that, if successful, it would definitely contribute to the adoption of remote laboratories.

The main goal of the OLAREX project is to offer to providers of formal and non-formal education an efficient way to improve their e-didactic and digital competences. For this purpose a training program is created with using ICT-based learning materials, remote laboratories, and e-learning methodologies. The project's primary target groups are the European secondary schools. More specifically: secondary school and university teachers, students and managers of schools, museum employees and their visitors, and other STEM education providers.

This paper describes the current influence of the remote laboratory on practical learning aspects of secondary sector of education. The key challenges faced by the teaching of science include insufficient hands-on laboratory usage in classrooms. The main objective of the paper is to present learning approach of adaptation and usage of remote experiments of WebLab-Deusto in curriculum of secondary school. The activity was organized in collaboration with secondary school teachers of P. Andrés Urdaneta School. Educators can benefit from different teaching methods (collaborative, inquiry-, and project-based learning) integrated in WebLab-Deusto. The teaching of Ohm's Law in Physics curriculum of secondary school was one of the topics executed during this research. The remote laboratory assignment for students was developed on Virtual Instrument Systems in Reality (VISIR) Open Lab Platform. The existing remote laboratories are more or less copies of hands-on ones. VISIR is a remote laboratory created by Blekinge Institute of technology (BTH) for designing, wiring and measurement of electric circuits. This main feature of VISIR allows one building a scenario of performing basic DC and low frequency AC circuits experiments related to Ohm's and Kirchhoff's laws. Moreover, the students will become familiar with instruments, components, manuals, data sheets, circuit wiring, and other laboratory work. In the paper the main principle of VISIR will be presented; the remote experiments executed by students will be shown. Finally, the result of integrating of remote experiments for study in Urdaneta School will be discussed.

Educational remote laboratories are a software and hardware tool that allows students to remotely access real equipment located in universities as if they were in a hands-on-lab session. Their integration in Content and Learning Management Systems (CMSs or LMSs) has been an active research topic for years, supporting mainly ad hoc solutions. A notable exception has been the use of federation protocols -commonly used for sharing laboratories from one university to other-, for actually sharing laboratories from a remote laboratory system to a C/LMS. This approach opened new doors in the simplification of the process, since it did not require the remote laboratories to make any type of change. The focus of this contribution is to provide a solution to decrease the number of functionalities required for creating an integration by providing a software component that reuses them. As shown in the contribution, this component has been implemented and two remote laboratory management systems (which provide access to multiple remote laboratories) are already supported, and a third one is under development. In the C/LMS side, all the LMSs supporting IMS LTI are supported, and HTTP APIs are provided for being supported by other systems. Indeed, the contribution describes its support in the Joomla CMS and in the Moodle 1.9 and dotLRN LMSs which do not support IMS LTI. The solution, called gateway4labs, is an open source initiative which targets to be used in production.

This paper describes the integration of a remote lab in a tool for educational digital circuits. Boole-Deusto is an educational software tool featuring truth tables, Karnaugh maps, Boolean expressions, finite-state machines and digital circuits. After creating the design through Boole-Deusto, the user can implement the circuit in a remote lab (WebLab-Deusto) with only a few mouse clicks. The user does not need the technical knowledge, time, hardware equipment and specialized software that would normally be required. These conveniences benefit teachers and students alike, especially those involved in basic courses in digital electronics, both at the university and high school levels.

LabVIEW is a development environment from National Instruments, focused on the automation of processing and measuring equipment, and it is and has been for years a crucial tool in Educational Remote Laboratories. Three features are key for this success: a) a visual programming language called G, so developers don't need to work with traditional “text” programming languages, therefore achieving a wider range of experiment developers; b) a strong industrial support and c) the “Remote Panels”, where the developer publishes the application automatically in a web browser. However, Remote Panels require a plug-in to run, not available for mobile devices neither all browsers in operating systems, and it clearly breaks with the ongoing web development trends, more interested in HTML5. This contribution shows how LabVIEW Remote Panels are used in Remote Laboratories, describing its inclusion in the WebLab-Deusto platform, and it describes the advantages and disadvantages of its use, comparing it with other existing approaches.

An educational remote laboratory is a software and hardware tool that allows students to remotely access real equipment located in the university as if they were in a hands-on-lab session. Federations of remote laboratories have existed for years: they are based on enabling two universities to exchange remote laboratories directly, without registering students of the latter on the former university. Integration of remote laboratories on Learning Management Systems (LMS) or Content Management Systems (CMS) have also been addressed in the past, enabling institutions to delegate the authentication or authorization of the experiments to the LMS/CMS. However, these integrations are usually achieved in an ad hoc way, integrating each particular laboratory to a LMS/CMS. This contribution studies the use of federation models to integrate remote laboratory management systems in LMS/CMSs, since both approaches (integrating a laboratory on an a external electronic learning tool, and integrating a laboratory on other laboratory) are essentially equivalent. The contribution defines two case studies to evaluate this approach, showing how this integration is achieved on a LMS (Moodle) and on a CMS (Joomla).

Until a few decades ago, face to face classrooms and hand-on laboratories were the common solution for teaching theory and practice. But, new e-Learning tools have emerged and learning methodologies such as blended and distance learning have taken an important space in learning initiatives. Among them are virtual and remote Labs which provide student with a learning environment where can carry out the experiments through Internet and acquire the needed skills to develop his future jobs. This paper describes the importance of virtual and remote labs and their usage in learning scenarios.

An educational remote laboratory is a software and hardware tool that enables students to remotely access real equipment located in the university as if they were in a hands-on-lab session. In order to be able to increase the curricula of universities, software infrastructures and toolkits that make the development and maintenance of remote laboratories easier arose, such as the MIT iLab project, the Labshare Sahara project, or WebLab-Deusto. Making different systems collaborate at infrastructure level is highly desirable so as to successfully share laboratories with different characteristics. This contribution summarizes the integration of WebLab-Deusto laboratories inside the iLab Shared Architecture, as well as the integration of iLab batch laboratories inside WebLab-Deusto.

Practical sessions are the backbone of qualification in engineering education. It leads to a better understanding and allows mastering scientific concepts and theories. The lack of the availability of practical sessions at many universities and institutions owing to the cost and the unavailability of instructors the most of the time caused a significant decline in experimentation in engineering education over the last decades. Recently, with the progress of computer-based learning, remote laboratories have been proven to be the best alternative to the traditional ones, regarding to its low cost and ubiquity. Some universities have already started to deploy remote labs in their practical sessions. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR), on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well.

The paper shows the results of an integration of the remote laboratory WebLab-Deusto-PLD at the "Programmable Logic" course of the Faculty of Engineering of the University of Deusto (Spain). Presented herein is a technical overview of the laboratory, a description of access to it, and an analysis of the user experience derived from conducted surveys since 2004. The surveys' analysis shows a correlation between two advantages of the remote experimentation: efficiency/usefulness and immersion/control. The prospective work includes an improving the WebLab-Deusto usability, an extension of the capabilities of the overall system and further its implementation in curricula.

The remote labs or WebLabs promote the experimentation in the studies of engineering allowing the access and control of real laboratory equipment through Internet. In general a WebLab is a client-server application where the client application can only be used from a PC, and it is not considered the use of mobile devices as potential clients. This is due to the fact that the WebLabs are designed from the hardware point of view, and not from the software engineering point of view. Any WebLab can be designed and implemented to be accessed using a mobile device, but only the AJAX technology can provide a unique solution for a wide range of platforms, including mobile devices. This work compares the different strategies to include mobile devices in remote labs and describes the benefits of using the AJAX approach.

The design of WebLabs has traditionally been focused on the hardware rather than the software side. However, paying more importance to the software side can bring about important improvements: richer collaboration among group members, better scalability, securer access and more natural anywhere at anytime access to the remote lab. Regarding this latter issue, enabling a user to access a remote WebLab not only through standard internet-connected PCs but also by means of their mobile devices can be very interesting and potentially advantageous. The core of this paper is to discuss the transformation of DeustoWebLab into a Web 2.0-compatible application accessible from mobile devices.
