2025 Ethical AI in Education: A Proposed Model for Responsible Integration
abstract
Artificial Intelligence (AI) is rapidly transforming the educational landscape, offering unprecedented opportunities to personalize learning, optimize administrative processes, and enhance student outcomes. However, alongside its benefits, the integration of AI into education presents significant ethical challenges that require structured and responsible approaches to ensure its effective and equitable use. This paper introduces the INTEGRITY AI Model, a structured and progressive framework designed to guide the ethical adoption of AI in educational settings. The foundation of the INTEGRITY AI Model is an initial diagnostic assessment that identified critical gaps in teachers' understanding of academic integrity, the subtle forms of misconduct facilitated by AI, and the need for continuous professional development in technological literacy. Based on these insights, the model addresses three key levels: Guiding Principles, which provide ethical guidelines and best practices to establish a shared foundation for teachers and students; Training Actions, which focus on capacity-building through specialized courses, workshops, and awareness initiatives to enhance ethical AI integration; and Impact and Empowerment, which prioritizes the dissemination of resources, the promotion of accessibility, and the creation of spaces for reflection and dialogue to foster a culture of academic integrity. This study underscores the importance of aligning the adoption of AI technologies with robust ethical frameworks, addressing both pedagogical and institutional dimensions. By incorporating actionable strategies and a scalable structure, the INTEGRITY AI Model serves as a replicable resource for educational institutions seeking to navigate the complexities of AI integration responsibly. The model's implementation highlights its relevance and effectiveness, as evidenced by the positive reception of its guides, workshops, and online resources. The results of this research affirm the value of structured ethical approaches in enhancing the responsible use of AI, promoting awareness, and equipping educators and students with tools to address ethical challenges. By fostering a reflective academic culture, the INTEGRITY AI Model maximizes the potential of AI technologies while ensuring their ethical and equitable application in education. This framework provides a path forward for institutions aiming to embrace AI's transformative potential responsibly and sustainably.

2023 Designing active and experiential remote laboratories: Key factors from the perspective of teachers designing learning activities
abstract
A remote laboratory is a software and hardware tool that enables students to access real equipment located somewhere else through the Internet. The access to the equipment is just the first part, for a correct implementation, the interaction, feedback and troubleshooting is vital. 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 naturally used by students. The installation and maintenance of multifunctional remote laboratories can represent high costs, that is the reason why some institutions choose to rent the equipment for short periods of time. Thus, two or more institutions can share different equipment to reduce costs. Furthermore, this enables a sharing economy where multiple institutions provide access to their laboratories to each other, in different economic models (freely or with a cost). However, the demand identified in times of pandemic has required great efforts on the part of engineering faculties to continue training their students. The COVID-19 pandemic suddenly paralyzed universities all around the world. During the COVID- 19 lockdown, universities switched to distance teaching and canceled face-to-face education affecting the way of teaching. IT staff was urged to find alternatives to train teachers in designing diverse learning activities to meet the learning objectives. This work presents the experience of implementing a group of remote laboratories in courses related to Electronics and Electric subjects at various levels of engineering. By incorporating the principles of Kolb's Experiential Learning Cycle, this work investigates key factors and pedagogical considerations for the design of effective remote laboratory activities. The findings highlight the importance of providing students with hands-on, experiential learning opportunities, even in remote settings, to enhance their understanding and application of theoretical concepts in engineering education. To date, the institution represented by the authors' research group has implemented over 44 courses with learning activities utilizing pilot remote laboratories, benefiting more than 375 students. This paper presents the main lessons learned from these experiences.

2023 The potential role of AI-based Chatbots in Engineering Education. Experiences from a teaching perspective
abstract
The irruption of Artificial Intelligence (AI) based chatbot tools is undoubtedly at the frontiers of education. AI chatbots in education has emerged as a promising solution to enhance the quality of education and to improve learning outcomes. As all new technology does, it has begun to generate news about prohibition, ethical aspects, anti-plagiarism detection tools, and a series of policies from different educational systems. However, we should not deny the positive aspects of these tools if they are well used. AI-based chatbots have interesting potential to help both teachers and students, who must learn to use them well for their own benefit. This article provides an overview of AI-based chatbots, particularly ChatGPT, an artificial intelligence language model developed by OpenAI. GPT, or “Generative Pre-Training Transformer” is a neural network trained to generate “human-like text” by predicting the next word in a sequence given a large dataset of examples. ChatGPT uses the neural network model and is used to generate responses to students' questions in real time, in the sense of a personal teacher assistant. Chatbots are designed to be able to carryon a natural conversation by understanding the context of the conversation, generating appropriate responses, and engaging in active interaction. Nowadays, this type of tool can generate more than just text; for example, the use of LaTeX code (using TeXGPT) or tools for coding and debugging programming exercises. This work explores the potential role that AI-based chatbots can have in engineering education, by examining the answers of a group of teachers' about how the use of AI-based chatbots can improve the learning process of the students in engineering education. The questions that teachers had to answer, from a pedagogical and technological perspective, are related to how chatbots can be integrated into the curriculum to enhance the efficiency of engineering education, their potential impact on the learning process, and actual examples of possible learning activities using AI-based chatbots in their courses.

2014 Teaching and promoting web accessibility in virtual learning environments: A staff training experience in Latin-America
abstract
Constant evolution of technology triggers a large myriad of research related to accessibility in Virtual Learning Environments (VLE). In the same way, international initiatives provide guidelines to create accessible web content, but educational institutions, especially in Latin-America (LA), are not aware of the VLE barriers that could affect students with disabilities. The fulfillment of accessibility standards in a virtual campus provides benefits for all the academic community that in some cases could face difficulties to learn through the VLE. This work proposes an innovative practice to implement, promote and include accessibility features in a VLE through an intensive training workshop based on best practices. This approach is addressed to technical staff involved in the installation, maintenance and support of e-Learning solutions in academic institutions, with a special focus on software and web engineering. A first staff training experience was implemented in seven countries in LA with more than 180 participants from 52 different Higher Education Institutions (HEI). Results from the experience manifest a growing interest from HEIs in accessibility topics and encourage improving the workshop materials for new editions. The design of Massive Open Online Courses (MOOC) based on the workshop will allow the initiative to reach a broader audience.

2014 Towards a methodology to inclusive curriculum design: An experience presented within an accessible virtual learning environment
abstract
Higher Education Institutions (HEIs) are constantly adopting Information and Communication Technologies (ICT) to improve and enhance the learning process. In this sense, constant evolution of assistive technologies helps users with disabilities to have a complete set of choices to access digital content while working with Virtual Learning Environments (VLE), but an intense training for stakeholders involved in curriculum design should be prepared to achieve an integral inclusive solution. This article proposes an innovative practice to implement, validate and promote a working methodology to produce an inclusive curriculum design, where teachers and staff administrators have a relevant role while designing, preparing and imparting accessible and inclusive courses. Teachers need to be instructed on how to generate accessible documents and how to provide truly accessible curriculum developments. This work presents an initiative promoted by ESVI-AL project, looking to improve accessibility in virtual higher education through the definition of systematic and replicable methodological processes for the design and implementation of accessible virtual curriculum developments. A first training experience for teachers in Latin-America is presented.

2013 Cloud-based Learning Environments: Investigating Learning Activities Experiences from Motivation, Usability and Emotional Perspective
abstract
Cloud education environments consider all the cloud services, such as Web 2.0 applications, content, or infrastructure services. These services form an e-learning ecosystem which can be built upon the learning objectives and the preferences of the learner group. A great variety of existing cloud services might be repurposed for educational activities and it can be taken advantage from already widely used services without steep learning curves on their adoption. In this article is presented the design, deployment and evaluation of learning activities using cloud applications and services. The experiences presented here are from Galileo University in Guatemala with students from three different countries in Central America and Spain. This study reports findings from motivational attitudes, emotional aspects and usability perception. Selected cloud-based tools were used for the different learning activities in three courses in various application domains. These activities include collaboration, knowledge representation, storytelling activities and social networking. Experimentation results obtained aim to demonstrate that students are eager to use and have new and more interactive ways of learning, which challenges their creativity and group organization skills, while professors have a growing interest on using new tools and resources that are easy to use, mix and reuse. Thus, future research should focus on incentives for motivating participation as well as on providing systems with high usability, accessibility and interoperability that are capable of doing learning orchestration.

2013 Automatic Test Item Creation in Self-Regulated Learning - Evaluating Quality of Questions in a Latin American Experience
abstract
The research area of self-regulated learning (SRL) has shown the importance of the learner’s role in their cognitive and meta-cognitive strategies to self-regulate their learning. One fundamental step is to self-assess the knowledge acquired, to identify key concepts, and review the understanding about them. In this paper, we present an experimental setting in Guatemala, with students from several countries. The study provides evaluation results from the use of an enhanced automatic question creation tool (EAQC) for a self-regulated learning online environment. In addition to assessment quality, motivational and emotional aspects, usability, and tasks value are addressed. The EAQC extracts concepts from a given text and automatically creates different types of questions based on either the self-generated concepts or on concepts supplied by the user. The findings show comparable quality of automatically and human generated concepts, while questions created by a teacher were in part evaluated higher than computer-generated questions. Whereas difficulty and terminology of questions were evaluated equally, teacher questions where considered to be more relevant and more meaningful. Therefore, future improvements should especially focus on these aspects of questions quality.

2011 A video-message evaluation tool integrated in the UNED e-learning platform
abstract
Use of multimedia services has become very important in learning process. This is due to the traditional approach of document based assignments not provide any feature which allows to evaluate some basic competences (oral communications skill, for example). In this paper, the UNED (Spanish University for Distance Education) solution will be presented focusing on user's interaction: lecturers and students. In the first case, the lecturer has to define a task and propose a solution (available only at the end of task availability). This solution is also video/audio based, so the student can learn about it and compare it with his/her solution. The student has several attempts, in order to try better responses and decides which of these attempts will be selected as final response. The whole interaction schema will be presented and how is integrated in the e-learning platform as a usual task (like document based tasks). This integration permits the use of all features of the platform evaluation tool, simplifying the evaluation process and tasks grading (no special procedures are required).
