Introduction
As pointed out by Campos et al. [1], internet-related technologies have had a noticeable impact on higher education, particularly in STEM fields, enabling global access to courses.A globalized educational experience also raises the level of heterogeneity among students due to varied cultural and educational backgrounds.Zawacki-Richter et al. [2] provides a comprehensive overview of the different areas in which AI is being applied in higher education, highlighting four main applications: (i) profiling and prediction; (ii) intelligent tutoring systems; (iii) assessment and evaluation; and (iv) adaptive systems and customization.In this context, artificial intelligence (AI), simulation-based, and e-collaborative tools play a key role in online and blended higher education.
The increasing internationalization of higher education leads to a more diverse student body with varied cultural, educational, and linguistic backgrounds.This diversity presents accessibility challenges, as educators must address the needs of students who may have different levels of proficiency in the language of instruction or varying familiarity with academic norms and practices.In addition, the trend towards interdisciplinary education means that students are increasingly required to acquire knowledge and skills across multiple domains.While this broadens educational opportunities, it also poses accessibility challenges for students who may lack foundational knowledge in certain disciplines.Likewise, the expansion of online education and lifelong learning initiatives has made higher education more accessible to a wider range of learners, including working professionals and adult learners.However, online courses may present accessibility barriers for students with disabilities or those who lack reliable internet access or digital literacy skills.Thus, for example, students with disabilities may require alternative formats for course materials, such as accessible documents or multimedia content with captions and transcripts.Additionally, human-AI interaction and collaboration solutions are currently available to assist individuals with disabilities [3].These technologies can motivate educators to incorporate them into educational environments, enhancing the learning experience for both students and instructors.The integration of human capabilities with advanced technologies is progressing swiftly.Complex computer systems utilizing machine learning (ML) algorithms can aid individuals with diverse abilities, executing human-like processes and complex tasks that are also applicable to educational contexts [4].
In this context, we define the concept of AISEC as the integrated application of artificial intelligence, simulation, and e-collaborative tools.This integration is visually depicted in Figure 1.Within each circle is shown which specific tools are being used for AI, simulation, and e-collaborative purposes, highlighting how they overlap and interact.This convergence illustrates the logic behind the definition of the AISEC concept.Based on this definition, this paper discusses how the use of these AISEC tools can also enhance accessibility in higher education analytics courses, taking into account different linguistic backgrounds and analytical competencies.Through a comprehensive review of existing literature and empirical results from practical implementations, the benefits of using AISEC tools to facilitate interactive participation in analytics courses are highlighted.In addition, the paper outlines practical strategies and best practices derived from real experiences carried out in different universities.The remaining of this paper is structured as follows: Section 2 explains how the impact of AISEC tools on accessibility in higher education analytics courses was investigated.Additionally, the criteria for conducting the literature review and selecting university experiences are specified.Section 3 provides an overview of related work.Section 4 describes some of the most popular AISEC tools that are being used in higher education analytics courses, taking into account accessibility.Then, Sections 5-7 present some recent experiences teaching these courses at three different universities in Spain, Ireland, and Portugal.Finally, Section 8 provides a summary of the main findings of this work, as well as suggestions for future research.

Methodology
The methodology is organized into two main phases: defining the criteria for conducting the literature review and establishing the criteria for selecting university experiences.
Therefore, for the first phase, the focus was on identifying relevant literature on educational accessibility and technologies in teaching analytical courses.In this paper, a systematic search was conducted mainly based on the academic databases Web of Science, Scopus, and Google Scholar.In this sense, a systematic search based on keywords including "educational accessibility", "educational inclusion", and "disability education" was conducted to clarify the scope and the challenges of educational accessibility.Additionally, the keywords "analytics courses" and "teaching technologies" were used to thematically analyze the most recent academic literature from the past five years in order to synthesize research findings.An association network diagram was then created to visualize the main themes in the literature, and other relevant teaching technologies were discussed to address identified gaps.The literature review utilizes representative literature to support general conclusions regarding the effectiveness of AISEC discussed with respect to its effectiveness in teaching analytics courses.Subsequent searches for AI, simulation, and e-collaboration tools were conducted separately, with a focus on filtering out literature targeting courses related to educational accessibility and analytics.
For the second phase of our research, the emphasis was on selecting and evaluating university experiences that implemented AISEC tools in their higher education analytics courses.In this case, three European universities were selected: the Universitat Politècnica de València (UPV), the University College Dublin (UCD), and the Universidade Aberta (UAb) of Portugal.These institutions were selected due to the firsthand experiences of the authors, either as professors or students, offering a mix of geographical and cultural diversity from Spain, Ireland, and Portugal.UPV, UCD, and UAb are well-recognized in higher education, ensuring the experiences evaluated occur within a rigorous academic environment.The authors' familiarity and prior relationships with these universities facilitated data access and the implementation of AISEC tools, allowing for detailed monitoring of the practical experiences.Furthermore, the results of the practical experiences in each of these universities are explained in Sections 5-7.Data collection includes active participation in the lessons, where we engaged with both the tools and the students.We collected and analyzed data provided by the software after each session and also gathered students' feedback on the use of these tools and their impact on the class.
To address ethical concerns during our research, given that some of the authors were participants in these educational experiences, either as students or professors, we took extra measures to ensure objectivity in the analysis regarding the use of AISEC tools in these universities.We maintained an objective approach to prevent any potential bias.This included separating personal experiences from data analysis and also obtaining feedback from other students in the courses to ensure that our conclusions were based solely on empirical evidence and not personal perceptions.The feedback obtained was collected with informed consent and strict anonymity in order to ensure the students' confidentiality.

Literature Review
In the digital era, ensuring the accessibility of education for all students has become an urgent issue.Therefore, this section will focus on educational accessibility, with an examination of the existing research literature.This discussion will address the ways in which authors address these challenges through technological innovation.

The Role of Accessibility in Education
Accessibility in education refers to equal learning opportunities and resources for all students that are diverse in many dimensions, including gender, race and ethnicity, age, socioeconomic status, ability, disability, and learning style [5].The flexibility of online education makes it an important tool for increasing equity during the learning process [6].This diversity, while enriching, also presents distinct challenges that educators must address to ensure equitable learning opportunities.Among this challenges, we can consider: 1.
Language barriers: One of the primary challenges faced by students from non-native language backgrounds is language barriers to comprehension and expression.These students often struggle to keep pace with their peers in understanding instructional materials and participating in classroom discussions.To address this issue, research advocates for the implementation of language support services, such as ESL (English as a Second Language) programs, which can provide tailored assistance to help these students develop proficiency in the language of instruction [7].

2.
Previous educational quality: The variability in the quality of prior education can result in significant gaps in foundational knowledge and skills among students.The student demographics in online education have changed, with 41.6% of online learners being over the age of 30 [8].Those who have experienced subpar educational settings may struggle to meet the academic demands of their new environments [9].To improve the accessibility of education, AI technology is widely used to help students improve teaching effectiveness and learning experience.Diagnostic assessments [10] can help identify these gaps early on, allowing educators to develop personalized learning plans tailored to each student's needs.

3.
Learning disabilities and special needs: Students with learning disabilities or special needs require specific accommodations and tailored instructional methods to succeed academically.These students face unique challenges that standard educational practices may not adequately address [11].The impact of the four most common disabilities on learning and the common solutions are illustrated in Figure 2. 4.
Cultural differences: Students from diverse cultural backgrounds may find it challenging to fulfill the social and academic expectations of their new settings [12].Culturally responsive teaching practices, which include incorporating diverse cultural perspectives into the curriculum and promoting an inclusive school culture, can help mitigate these issues.By valuing and respecting cultural diversity, educators can create a more welcoming and supportive environment for all students.This view aligns with the role of open educational resources (OERs) in promoting inclusive learning.Hockings et al. [13] highlighted that OERs provide flexible and accessible learning materials that cater to diverse student needs.5.
Socioeconomic disparities: The uneven distribution of resources is a serious impediment to the accessibility of education.In Norway and Switzerland, 95% of students are fortunate enough to have access to electronic devices, whereas in Indonesia, only 34% of students have such access [14].Students without available resources face a host of socioeconomic challenges that affect their educational experiences.These students often lack access to essential resources such as technology, learning materials, and extracurricular opportunities, which are crucial for holistic development [15].To combat these disparities, schools can implement financial aid programs that alleviate the economic burden on families.Providing free or low-cost learning materials and creating supportive environments where all students have equal access to educational resources can significantly enhance the learning outcomes for socioeconomically disadvantaged students.

The Use of Technology in Teaching Analytical Courses
Analytics courses should cover a multi-stage framework related to data, such as acquisition, preparation, analysis, visualization, and interpretation, combining multiple fields such as statistics, business domain knowledge, and computer science to help students acquire relevant knowledge and skills [16].Figure 3 shows the association and distribution of keywords in 171 papers related to analytics courses and teaching technologies recorded in Web of Science over the past five years.The size and color of the circles indicate the frequency of the keywords in the study and their relevance to other keywords, respectively.Topics such as educational technology, online learning, ML, and AI have gained particular attention in recent years.Massive online open courses (MOOCs) provide teaching materials, assessment, and collaboration tools to thousands of students [17].These online education platforms democratize access to education and enable learners from diverse backgrounds to acquire analytical knowledge and skills, regardless of their location or physical limitations.The rapid development of analytical tools such as ML and AI can greatly improve the effectiveness of data analysis [18].Incorporating AI and ML into the course equips students with the necessary skills to utilize these powerful tools, preparing them for the data-driven challenges of the future.
In addition to the highly valued analytical course related topics of online education, AI and ML are shown in Figure 3. Simulation and e-collaboration should also be considered powerful tools for teaching analytical courses [19,20].Simulation tools help students to conduct experiments and analyses in a virtual environment, enhancing their understanding of complex concepts.On the other hand, e-collaboration tools promote interaction and communication among students and between teachers and students, increasing the engagement and effectiveness of learning.Therefore, online education, AI, simulation, and e-collaborative tools can all be used as technologies for teaching analytics courses to improve the quality and efficiency of education.

AI Tools for Teaching Analytical Courses
The capabilities of AI in processing large data sets, generating insights, and facilitating customized learning experiences have made it increasingly popular in education.From the development of intelligent online and web-based education to the integration of computer systems with technologies like humanoid robots and chatbots, AI has been widely accepted by educational institutions and used to perform instructional tasks autonomously or with teachers [21].Branches of AI such as ML, deep learning, and natural language processing work together to create personalized learning platforms and improve educational accuracy by building intelligent tutoring systems, agents, and collaborative learning systems that respond to students' needs and support teachers' decision making [22].The integration of technology and AI is particularly expected in analytics teaching.

Various AI Tools Used for Teaching Analytics
In terms of AI tools for teaching analytics courses, Asamoah et al. [23] describe the pedagogical approach used to design a big data analytics course in the general management information systems (MIS) program at Midwestern University.The course modules cover various technologies: (i) the Apache Hadoop ecosystem for large-scale data collection and management; (ii) the IBM BigInsights and InfoSphere Streams for static and dynamic data; and (iii) Teradata Aster, a Big Data platform supporting MapReduce-enabled analytics.The course also utilizes Gephi for data visualization, and a combination of Tableau with Hortonworks, Teradata, and IBM tools.Advanced analytics techniques such as network analytics and stream mining are included.Survey results demonstrate the course's effectiveness in helping students acquire relevant knowledge and skills.Similarly, Eckroth [24] describes Stetson University's Big Data Analytics course for computer science students, featuring data preprocessing with Linux tools, distributed processing with Hadoop MapReduce and Spark, and database querying with Hive and Google BigQuery.Student feedback indicates the course effectively teaches parallel and distributed computing frameworks and techniques used in industry.
Business schools teaching business intelligence and analytics (BI&A) should integrate BI&A content into their core syllabus.Allil [25] proposed a framework for marketing analytics education that incorporates AI tools like ML and predictive analytics, including case studies of companies using AI-driven marketing analytics.Students use resources such as the UCI Machine Learning Repository.Also, utilize ML repositories such as Kaggle, Data.gov, and Google Dataset Search, and learn visualization tools like Tableau, Power BI, and Python, along with ML tools like scikit-learn, TensorFlow, and R's caret package.Sentiment analysis tools like TextBlob, VADER, and Stanford CoreNLP, and NLP libraries like NLTK, SpaCy, and Gensim are also included.Applications include predictive analytics for customer behavior, ML for customer segmentation and product recommendation, deep learning for targeted advertising, automated content creation, and voice assistants for customer interaction.Advanced data analytics courses incorporating robotic process automation (RPA) and AI in accounting graduate programs at northeastern U.S. public universities have proven effective in meeting learning objectives [26].
AI tools can also empower coding-related courses as a major theme in analytical courses.Large-scale language models (LLMs) such as the AI chatbot ChatGPT and the generative AI tool GitHub Copilot have shown their potential as programming learning tools [27].González-Carrillo et al. [28] have added support for automated Jupyter notebook evaluation to the UNCode auto-grader, deployed at https://uncode.unal.edu.co(accessed on 1 July 2024), to facilitate instructor-student interactions.This enhancement allows instructors to configure the Jupyter notebook grader through an easy-to-use user interface and provides students with both summative and formative feedback related to programming assignments.The tool's application in AI-related courses-Introduction to Intelligent Systems and Machine Learning-at the Universidad Nacional de Colombia during the first semester of 2020 received positive feedback from students.Vittorini et al. [17] also developed an automated grading tool for MOOC assessment activities based on R commands and natural language annotations, improving grading efficiency and helping students achieve better learning outcomes.
Table 1 summarizes some AI tools that are used to teach the analytics courses in the different colleges mentioned in the paper, some of which are used for the AI skills required in the analytics courses themselves, some of which are used to help in other related courses such as those related to "Programming", and some of which are used to provide feedback to both students and teachers, as stated above.The Reference column cites case studies where these tools have been applied to enhance the student learning experience.

AI-Based Language Support Tools for Non-Native Speakers
The diversity of both web-based and face-to-face classrooms is growing.The increasing globalization of the world economy continues to drive population mobility and bring greater cultural and linguistic diversity to communities and educational systems [29].Current MOOCs are also attracting a wide variety of demographically diverse students of all ages and from 196 countries across the globe [30].Analytics course are also bound to attract a diverse group of students, including international students, non-native speakers, and students with varying language abilities.Today's classrooms need to be more inclusive and technology-integrated than ever before [31].Some of the AI-based language support tools include Presentation Translator and AI Speech Recognition, which offer real-time language translation and voice recognition capabilities [32].Additionally, voice assistants or smart speakers and chatbots [33,34] are widely used for interactive communication and educational purposes.
AI-based language support tools have shown potential in the field of general education to help non-native speakers overcome language barriers and enhance their learning experience to improve inclusiveness and accessibility in the classroom.AI-based solutions such as Presentation Translator can provide real-time captions and enable students to listen to or read content in their native language through AI speech recognition.These technologies not only benefits students who are not native speakers or who are hearing impaired, but also help people with visual limitations to access and understand educational materials more effectively [32].Voice assistants, including Google Assistant, Siri, and Cortana, utilize cloud computing to integrate AI to allow students to search for materials, reference questions, articles, and books by simply mentioning keywords, displaying the information being searched for in the form of text or images [32].Similarly, Jordan et al. [35] investigate the use of LLMs (e.g., OpenAI's GPT) to generate programming exercises in multiple languages.
In addition, chatbots are promising in education.Properly designed chatbots can address logistical and diversity issues, from simple Q&A to scenario-based classrooms, filling gaps in teaching and learning [36].The research of Chen et al. [33] on the chatbot Sammy, developed using Juji (https://juji.io,accessed on 1 July 2024), shows that chatbots can be engaging and responsive conversational learning tools, helping students learn AI concepts interactively and confidentially.Mageira et al. [34] use the Snatchbot platform (https://snatchbot.me,accessed on 1 July 2024) to develop AsasaraBot, an educational AI chatbot that teaches cultural content about the Minoan civilization in English or French.Evaluations in Greek language schools showed it provides instant feedback and maintains student interest through interactive dialogues.Companies like Google, Microsoft, IBM, and Amazon offer platforms for designing, developing, and testing chatbots.

Simulation Tools for Teaching Analytical Courses
In STEM fields, students often encounter complex models, including NP-hard problems that test their analytical skills [1].McHaney [37] emphasizes expanding simulations beyond traditional settings.For instance, in a cloud computing course, simulations help develop web service emulations for efficient software testing.In Big Data courses, simulations generate data sets for learning analytics, allowing students to visualize and understand model outcomes effectively.Furthermore, simulation software tools offer simulation capabilities for business, manufacturing, and logistics systems [38].This enables students to experiment with scenarios safely and cost-effectively.The Beer Game, another educational tool designed to teach logistics, includes online versions, extended supply chain models, and a virtual reality version [39].SimEd, a simulation package for R, was designed with a pedagogical focus and enhances R's utility for simulation courses with text-based, visualization, and animation teaching methods in discrete-event simulation [40].Table 2 summarizes a selection of simulation tools that are utilized in educational settings to teach various analytical concepts.Due to constant updates and innovations, a single simulation tool can be applied in various educational contexts; therefore, each tool is listed with its primary learning context.Additionally, the Case Study column references case studies demonstrating the practical applications and effectiveness of these tools in enhancing student learning experiences across different educational disciplines.The variety of simulation tools outlined in Table 2 shows some of the diverse applications and learning contexts supported.They are employed to help students develop a deeper understanding of complex systems and improve their analytical skills, enabling them to apply theoretical concepts to real-world scenarios.This integration not only improves understanding and retention of challenging topics, but also prepares students for real-world challenges in their respective fields.

Discussion of How Simulation Software Enhances Experiential Learning
The ideal scenario would involve frequent opportunities for students to engage in real-life problem-solving situations.However, these opportunities are often limited, which restricts students' ability to apply theoretical knowledge in practical settings.Real-life contexts may not consistently provide sufficient or timely opportunities to practice and evaluate the outcomes of decisions, especially in critical situations where consequences unfold slowly or sporadically [51].Such limitations highlight the need for alternative approaches, like simulation software, which provides a practical solution to these limitations by offering an environment where students can engage in problem solving without the constraints of real-world timing and resource availability.This type of software provides an interactive environment that allows students to apply theoretical knowledge gained in the classroom to practical and real-world scenarios.This approach not only helps students engage more effectively but also deepens their understanding and retention of complex analytical techniques.Through interactive simulations, students can explore various data sets and scenarios, experiencing the impact of their analytical decisions firsthand and learning from immediate feedback, therefore increasing both the effectiveness and enjoyment of the learning process [52].Also, the integration of advanced technologies like virtual and augmented reality into simulation software offers a more immersive learning experience [53].
Furthermore, in the discussion of how simulation can enhance experiential learning, research shows the advantages of adopting AI-driven and simulation-based approaches.These methods not only enable students to solve analytical tasks more effectively than traditional learning approaches, but also promote critical thinking and analytical skills necessary for solving complex problems [54].With the use of AI technologies, simulation software can analyze students' interactions and performance, offering them personalized feedback and creating learning paths that are specifically customized to the specific needs and strengths of each individual [55].In other words, simulations can be adjusted and customized to the student's needs in order to match their learning stage, ensuring they are neither overwhelmed nor under-challenged.Also, simulation software enhances practical application skills and promotes collaborative learning by providing a safe environment for students to work together and experiment with and learn from failures without the fear of real repercussions or damage [56].

Examples of Simulation-Based Exercises for Teaching Statistical and Analytical Concepts
The work by Kuiper and Sturdivant [57] presents innovative simulation exercises designed to overcome common challenges in teaching complex statistical concepts that are difficult to address through traditional textbook methods.These simulations, suitable for educational levels ranging from undergraduate to graduate, offer practical experiences in data collection and analysis.One notable simulation involves an online tangrams game where students manipulate shapes to solve puzzles, collecting data on variables like puzzle completion times under different conditions, which may include factors such as the player's gender or background music.Another simulation, introduced by Kuiper and Sturdivant [57], is the 3D TigerSTAT game, where students take on the roles of wildlife researchers in a virtual preserve.Here, they estimate the age distribution of Siberian tigers by analyzing the extent of black pigmentation on the animals' noses, using this as an indicator of age.Through this exercise, students apply simple linear regression to model these age relationships and explore the effects of sampling variability on their conclusions.Kim and Hardin [58] have designed an exercise based on Google Calendar.In order to gather data, students have to answer the question of how they spend their time.This question is the starting point for learning tasks in data collection and analysis for undergraduate students.These students were tasked to document their daily activities such as sleeping, studying, and socializing using this application over 10-14 days.Then, these data were exported and imported into R, using R Markdown templates to guide students through a structured data wrangling process, using tools such as dplyr and lubridate.
Similar to previous examples, Bulmer and Haladyn [59] introduce a virtual environment known as "the Island" to teach statistical concepts through simulation-based exercises.This learning platform facilitates epidemiological analysis by allowing students to explore genetic backgrounds, geographic relationships, and disease spread among a virtual population, offering the students the opportunity to conduct more real experiments of their own choosing as part of a introductory statistics course.Moreover, Arinze [60] highlights the use of MISSimulation.com, a web-based election simulation.This simulation provides an interactive educational experience, enabling students to understand the concepts of data analytics through practical application [60].Students initially play against the computer for practice and eventually compete against each other or continue against the computer to determine their score for the course.Throughout this process, they learn about different aspects of analytics, including descriptive, diagnostic, predictive, and prescriptive analytics.

The Use of e-Collaborative Tools for Teaching Analytical Courses
In today's world, using technology in education is very important, especially for analytical courses that require interaction and problem-solving skills [61].In this sense, e-collaborative tools have become fundamental for knowledge transference and facilitating real-time collaboration between students and teachers.This section explores various e-collaborative tools transforming online learning environments for analytical courses, making learning more accessible and engaging while encouraging teamwork, essential for solving complex analytical problems.Microsoft Teams and Google Meet are good examples of collaborating tools, each aligning with their respective ecosystems, Microsoft Office 365 and Google Workspace, respectively, facilitating communication and collaborative efforts through integrated tools [62].Microsoft Teams offers a unified interface supporting various communication forms and allows simultaneous document editing.Google Meet simplifies meeting scheduling and management, supporting high-definition communication and secure interactions [63].Other platforms like Zoom and Notion have also become effective for teaching analytical courses.Zoom facilitates dynamic interaction and simulates a virtual classroom environment [64].Notion, a multifunctional workspace, enables users to manage learning activities and supports collaborative learning [65].All of these e-collaborative tools, along with others, are summarized in Table 3.Currently, many platforms are widely used in modern education.However, not all are beneficial for teaching analytical courses, requiring an examination of their general advantages and disadvantages.For instance, Zoom and Google Meet offer advantages such as an enhanced accessibility and flexibility, which help students and instructors to engage from anywhere in the world.This feature is particularly beneficial for analytical courses that attract international students or part time students who may have mobility or scheduling issues [63,64].Furthermore, tools like Microsoft Teams and Cisco WebEx integrate functionalities such as whiteboards, creating polls, and breakout rooms.These have the advantages of making classes more interactive and allow a real-time feedback among students [62,66].
The aspect of student collaboration is also an advantage that these platforms offer.They promote a collaborative environment where students can easily communicate and work together on group projects and discussions.For example, features like shared documents and simultaneous editing offered by Google Workspace and Notion allow multiple students to work on the same project in real time.Moreover, platforms such as Notion and Google Workspace facilitate seamless sharing of resources and real-time document collaboration.This is especially useful in analytical courses where students frequently work on projects requiring collective input and ongoing revisions.Additionally, tools like VizGroup offer specialized features for data visualization and analysis, which can be tailored to the specific needs of a course or project, allowing educators to design more effective and engaging learning experiences adapted to the analytical courses curriculum.These e-collaborative platforms are important to improving not only problem-solving skills but also interpersonal and leadership capacities [68].Specifically, in business analytics courses, these tools allow students to practically apply statistical models and business strategies within a collaborative virtual workspace, narrowing the gap between theoretical knowledge and practical implementation [19].
After highlighting the advantages of the several e-collaborative platforms mentioned, it is equally important to address some potential drawbacks these tools might imply in teaching analytical courses.One significant concern is the potential for reduced face-to-face interaction, which can impede the development of deeper interpersonal relationships and communication often captured through physical and informal interactions [69].Additionally, the reliance on technology introduces the risk of technical issues such as connectivity problems or software glitches, which can disrupt the flow of instruction and affect the learning process [70].Finally, the access to these platforms might also lead to issues of over-reliance, where students might become too dependent on digital tools for learning and collaboration, potentially undermining the development of critical thinking and problemsolving skills that are required in more traditional approaches [71].

Exploration of Accessibility Features in Platforms like Teams and Google Meet
As previously mentioned, real-time collaboration tools have become essential in facilitating synchronous interactions and collaborative learning experiences.The Web Content Accessibility Guidelines (WCAG) are essential to ensure that people with disabilities can make use of online web and platforms.These guidelines provide an accessibility framework that includes providing textual alternatives for non-textual content, making it easier for users to view and hear content, and ensuring that user interfaces are navigable and operable [72].As educational institutions and workplaces increasingly rely on these tools for day-to-day operations, adherence to WCAG ensures that no one is excluded.WCAG compliance is divided into three levels: Level A, which addresses the most severe accessibility barriers; level AA, which addresses general barriers to ensure usability; and Level AAA, which is the highest standard that improves accessibility for all the users [73].
Tools such as the ones highlighted in Section 4.3 provide features that account for the accessibility for users with different needs, particularly in online and blended education settings.These platforms share common accessibility features, including live captioning, screen reader support, keyboard shortcuts, and high-contrast themes.However, as Table 4 shows, they also have strengths and areas for improvement.While all platforms provide basic accessibility features, only Microsoft Teams includes an immersive reader, making it particularly useful for users with dyslexia.A study of the experiences of people with disabilities using these tools showed that none of them were considered fully accessible, and usability varied significantly.For example, Zoom was noted for better captioning and overall preference among users due to its simplicity and reliability, whereas Microsoft Teams was recommended for its better integration with assistive technologies and high-quality automatic captioning that includes speaker labels, making it easier for hearing-impaired users to follow conversations [74].All platforms currently achieve WCAG 2.1 AA compliance.This level ensures that general usability barriers are addressed, making the platforms accessible to most users.However, further improvements are needed to reach the final level.Reaching this higher level would involve better customization of user interfaces, better integration with a full range of assistive technologies, and more advanced text customization options.

Experiences at Universitat Politècnica de València
The Universitat Politècnica de València (UPV) (https://www.upv.es,accessed on 1 July 2024) is organized into 14 schools and faculties that span the fields of engineering, architecture, social sciences, and arts.UPV is consistently recognized as one of the leading technical universities in Spain and has achieved prominent positions in various national and international rankings as, for example, the U-ranking (https://www.uranking.es/ranking,accessed on 1 July 2024).In this section, it will be highlighted what steps has taken the UPV for integrating AISEC tools across some of its undergraduate and Master's degree programs.

Fishbanks: A Simulation for Sustainable Resource Management
Within the Master in Business Administration (MBA), the incorporation of the Fishbanks simulation into the Corporate Social Responsibility (CSR) course is noteworthy.This multiplayer internet simulation, developed by Dennis Meadows, John Sterman, and Andrew King, immerses participants in the roles of fishermen aiming to maximize their wealth in a competitive environment [75].The simulation challenges students with dynamic fish population models and economic competition, requiring them to buy, sell, and construct boats, choose fishing locations, and negotiate with other players, thereby demonstrating the complexities of sustainable resource management within a shared ecosystem [76].The integration of this Fishbanks simulation into the MBA curriculum was managed by a professor with prior experience in using this educational tool.This involved organizing and distributing access credentials and creating accounts for each student, ensuring full participation.To maximize the experience, the professor also conducted a training session to familiarize students with the simulation's interface and deepen their understanding of CSR and sustainable management.The use of this simulator significantly enriched the educational experience within the CSR course, providing students with practical insights into analyzing and managing sustainability issues effectively.Through this simulation, students gain a deeper understanding of the theoretical concepts of resource depletion, competitive dynamics, and strategic decision making in an interactive learning environment.The feedback from the students has been positive, emphasizing the simulation's role in improving engagement and practical application of the course content.

Markstrat: A Simulation for Marketing Management
Following the integration of the Fishbanks simulation, UPV extended its use of AISEC tools by incorporating the Markstrat simulation into the Marketing Management course to further improve the analytical and practical skills of the students in the marketing field.In the Markstrat simulation, students have the task of making a series of strategic decisions regarding product portfolio, research and development, marketing mix, and sales force allocation [77].The main objective is to outperform competitor companies in terms of market share, financial performance, and brand value.The dynamic nature of the simulation requires students to analyze market trends, consumer behavior, and competitive moves, fostering a deep understanding of strategic marketing principles in practice [78].To implement Markstrat effectively, the professor organized an introductory session to cover the basic mechanics of the simulation and the strategic concepts it aims to teach.Additionally, there were regular debriefing meetings in order to discuss the outcomes of each decision cycle, allowing students to reflect on their strategies and learn from both their successes and mistakes.The impact of this simulation within the Marketing Management course is remarkable.Students reported that it provides an invaluable perspective on the complexities of market competition and strategic decision making.It not only complements the theoretical knowledge provided in lectures but also allows students to experience the consequences of their own strategic choices in a risk-free environment.

Gestionet: A Finance Simulation for Financial Management
Gestionet is used in the Financial Management Advanced Techniques course.This is a business management simulator that focuses on the financial management aspect of running an industrial company.In the Gestionet finance simulation, students are tasked in managing budgets, optimizing investment portfolios, and developing funding strategies to enhance their own company growth and stability [79].To effectively implement Gestionet, the professor introduced the main functions of the simulator and the necessary financial concepts needed in order to ensure that students are fully prepared to use the simulator.An advantage of Gestionet is that it reduces the emphasis on marketing and strategy decisions, automating these to allow students to focus solely on the financial challenges, making it more adequate for the already taught contents of the Financial Management Advanced Techniques course.Throughout the simulation, students compete against up to ten different virtual companies, managed by their classmates, in this way creating a competitive marketplace.This competitive element is designed to mimic real market conditions and fosters a deeper understanding of financial management in a live, competitive environment [79].Also, from the second session onward, before students were allowed to make any new decisions, there was a class gathering.These regular debriefing sessions allowed students to analyze the outcomes of their decisions with their professor, learn from their experiences, and refine their strategies in subsequent rounds.

Implexa: An Evolutive Beer Game Simulation for Logistics
The subject of logistics is studied in the Master's Degree in Organization and Logistics Engineering and in the Bachelor's Degree in Business Administration.In order to learn about the supply chain, students make use of IMPLEXA (http://www.implexa.net,accessed on 1 July 2024).This software is an evolutionary game based on the classic Beer Game, designed to provide practical experience and help students learn about supply chain management in today's business context, where each player or student manages a company that is part of a supply chain.The activity is divided into two parts, starting with an initial round in which students play independently, without communicating with each other.This lack of planning and coordination between the companies in the supply chain can cause a bullwhip effect and decrease the efficiency of the whole.In the next round, students are free to share information and communicate, which facilitates the coordination of decisions and actions taken.In this round, the results improved significantly and the bullwhip effect was reduced thanks to the synchronization and integration between the students.Table 5 presents a comparative overview of various KPIs of the supply chain between two different rounds.The results of the second round, detailed in Table 5, show significant improvements in all aspects measured.In particular, total costs decreased by 14%, lead times were reduced by 61%, and stock levels were significantly reduced while fully satisfying customer demand.This efficiency improvement and 68% reduction in service costs demonstrate how strategic information sharing can mitigate the bullwhip effect and optimize overall supply chain performance.

LLOG VR: Virtual Reality for Logistics
Another didactic simulation tool used at UPV is LLOG VR (http://www.llog.es/vr.html, accessed on 1 July 2024).This software incorporates virtual reality to simulate a logistics environment, allowing students to experience first-hand the actions and decisions involved in logistics processes, with the possibility of performing actions such as order reception and preparation, shipping, warehousing, and inventory management, among others.This simulator represents a "Learning Factory", since it reflects the processes and technologies of a real industrial environment, offering an educational platform that brings students closer to the practical challenges of the logistics sector.A case study presented by Solanes et al. [80] during the 2022/2023 academic year at UPV explored the impact of this tool on logistics education.The results revealed that, although only 11% of the students had previous experience with virtual reality devices, the tool was highly rated in terms of usability, with an average score of 87.08 out of 100.In addition, due to the fact that it was necessary to be at the front of the classroom stage for this activity to take place, one student's experience highlighted the potential of virtual reality to mitigate personal problems such as stage fright.Tasked with demonstrating a robotic system, this student entered the metaverse with nervousness, but soon began to concentrate deeply on the virtual demonstration and her anxiety disappeared [80].

Discussion on Accessibility and Usability in UPV
In terms of usability, Markstrat, Gestionet, and IMPLEXA are designed to be user friendly, requiring no prior computer skills or software installation.Additionally, they offer several educational resources, such as free learning guides, webinars, and a comprehensive user guide to aid both participants and educators.Although various simulation tools, such as Markstrat, Gestionet Fishbanks, and LLOG VR, promote general accessibility and usability, they lack specific features for individuals who are blind or colorblind.While the simulation provides valuable educational experiences in several areas and subjects, further steps are needed to ensure it is fully accessible to all students, regardless of visual impairment.Futhermore, some tools used at UPV are characterized by fast and continuous actions (e.g., IMPLEXA).Direct and constant stimulation can help to keep the attention of some people with ADHD focused on a specific task.On the other hand, individuals with autism may suffer from sensory overload, fatigue, or stress due to continuous interactions, because of the lack of anticipation and preparation between each task or action.
