1 Introduction and Background

In recent years, the integration of technology into education has brought about transformative changes in the way learning is delivered and accessed. Learning Management Systems (LMS) have emerged as powerful tools that facilitate the creation, management, and delivery of educational content in both traditional and online settings. While the adoption of LMS platforms has led to increased convenience and flexibility, it has also raised concerns regarding equitable access for all learners, including those with disabilities. As digital learning continues to evolve, the accessibility of LMS becomes a critical consideration in ensuring that education is truly inclusive. Moreover, characteristics and features that could transform LMS into advanced LMS from a technical perspective include learner profiling; customization/personalization/differentiated learning; ubiquitous learning; active knowledge making; multimodal meaning; recursive feedback; collaborative intelligence; and metacognition. Although implementation and adoption of the aforementioned are relatively slower in pace, learners and educators would benefit immensely, especially as these evolve over the next few years. We foresee such technologies having a significant role in enhancing equity, accessibility, inclusion, diversity and understanding and support for learners and therefore propose that they generally be considered more in the development of LMS.

1.1 Accessibility Standards and Regulations

To address the issue of digital accessibility, various international standards and regulations have been established. Notable among these are Section 508 of the Rehabilitation Act, the European Standard EN 301 549, the Americans with Disabilities Act (ADA), and the Web Content Accessibility Guidelines (WCAG) developed by the World Wide Web Consortium (W3C). These standards provide a framework for evaluating the accessibility of digital platforms, including Learning Management Systems. Institutions and organizations have increasingly recognized the importance of adhering to these standards to ensure that their educational content and platforms are accessible to individuals with disabilities.

Section 508 (U.S. General Services Administration, 2023) refers to a critical component of the Rehabilitation Act of 1973 in the United States, which mandates that federal agencies make their electronic and information technology accessible to people with disabilities. This includes Learning Management Systems (LMS) used in digital education. Compliance with Section 508 ensures that students and educators with disabilities have equal access to educational resources and opportunities. In the context of digital education, Section 508 plays a pivotal role in fostering inclusivity and eliminating barriers for individuals with diverse needs.

Across the Atlantic, the European Standard EN 301 549 (ETSI, CEN, & CENELEC, 2021) establishes accessibility requirements for ICT products and services, including those used in education. Developed by the European Telecommunications Standards Institute (ETSI), this standard aims to create a more inclusive digital environment. EN 301 549 considers a wide range of disabilities and ensures that learning materials and platforms, including Learning Management Systems, are designed to accommodate diverse learners. In the realm of digital education, adherence to this standard enhances accessibility, creating an environment conducive to learning for all.

The Americans with Disabilities Act (ADA) (U.S. Department of Justice Civil Rights Division, 2008) is a landmark piece of legislation in the United States that prohibits discrimination against individuals with disabilities. In the context of digital education, ADA compliance is crucial for ensuring that online learning platforms, including Learning Management Systems, are accessible to all students and educators. ADA extends beyond federal agencies to cover a broader spectrum, emphasizing the importance of inclusivity in the digital education landscape.

The Web Content Accessibility Guidelines (WCAG) (W3C, 2024) provide a comprehensive set of recommendations for making web content, including educational materials on Learning Management Systems, more accessible. Developed by the Web Accessibility Initiative (WAI), these guidelines are internationally recognized and serve as a benchmark for digital inclusivity. Adhering to WCAG ensures that educational content is perceivable, operable, and understandable by a diverse audience, reinforcing the principles of universal design in the realm of digital education.

1.2 Digital Inclusion in Education

The concept of digital inclusion in education goes beyond compliance with accessibility standards; it embodies the principle that all learners, regardless of their abilities, should have equal access to educational opportunities. Accessible LMS platforms play a pivotal role in removing barriers to learning for individuals with disabilities. A study by Burgstahler and Cory (2008) highlights that accessible online learning environments not only benefit students with disabilities but also enhance the overall learning experience for all students by providing diverse means of engagement and interaction.

Accessible LMS platforms encompass a range of features and technologies designed to accommodate different types of disabilities. These include video subtitles to aid individuals with hearing impairments, easy navigation and interactivity options for intuitive use, screen reader support for visually impaired users, accessible text editors for content creation, support for accessible course content, high-contrast themes for improved visibility, and keyboard accessibility for those who rely on keyboard navigation.

While substantial progress has been made in improving the accessibility of LMS platforms, challenges persist. These challenges range from ensuring that accessibility features are effectively implemented to keeping pace with evolving technologies. Future research in this domain should address the practical implementation of accessibility standards and explore innovative solutions to enhance the overall usability of LMS platforms for individuals with disabilities.

In conclusion, the accessibility of Learning Management Systems is a pivotal aspect of modern education, reflecting the commitment to inclusivity and equitable access to knowledge. This literature review sets the stage for a comprehensive examination of LMS platforms, evaluating their adherence to accessibility standards and the presence of key accessibility features. The study aims to contribute to the ongoing dialogue on accessible digital education, providing valuable insights for educators, institutions, and learners alike.

1.3 Literature Review on Accessibility in LMS

In the literature, many papers explore whether LMS conform to accessibility standards and the level to which they do. Most LMS include accessibility barriers that make the creation of accessible e-learning environments difficult for teachers and administrators (Calvo et al., 2014). Calvo et al. (2014) evaluated the accessibility of the Moodle authoring tool with a study focused on visual impairment. According to the World Health Organization (WHO), an estimated 2.2 billion people have a near or distance vision impairment (WHO, 2023). Visually impaired users confront numerous difficulties daily when accessing web pages and online content. The authors mention two studies (Creven, 2003; Disability Rights Commission, 2004) that concluded that visually impaired users using screen readers were found to take three times as long as non-disabled users to complete a given task. Common problems faced by screen reader users include the lack of labels associated with controls like inputText, complex Web page structures and layouts, the lack of alternative texts for images, the impracticality of certain navigation techniques, inadequate color contrasts used, and incorrect size of elements (Disability Rights Commission, 2004).

Especially in LMS, visually impaired users often face difficulties in accessing online courses or learning content, while visually impaired teachers and administrators face difficulties in uploading their learning materials and managing their courses (Calvo et al., 2014). It is important to note here that, regarding LMS, besides the system itself, all documents and resources created by the teachers and presented via the LMS should also be accessible. For example, screen reader users require alternative text in all images, while hearing-impaired users require appropriate subtitles for videos (Calvo et al., 2014).

Regarding studies that evaluate LMS according to accessibility guidelines, it is mentioned that in most studies, LMS like Moodle, dotLRN, Blackboard ATutor, and Sakai have been found to contain serious barriers to accessibility with respect to WCAG 1.0 and ATAG 2.0 (Calvo et al., 2014; Iglesias et al., 2014; Power et al., 2010). Accessibility problems for visually impaired users in Moodle were also found in the diverse images used to convey information and the lack of headings in the application (Moreno et al., 2012). Hence, Moodle did not conform to ATAG 2.0 or WCAG 2.0. Calvo et al. (2014) conclude with recommendations for improving the accessibility of Moodle interface and the content created therein, the most important of which are: checking the accessibility of any external elements before using them in Moodle, avoiding common accessibility errors, and providing mechanisms to enable authors to avoid mistakes such as buttons for the cancellation of each task, mechanisms to undo actions executed, functionalities to periodically save the actions executed to prevent information loss, ways to save user preferences regarding auto-saving, colors, font size, etc.

In Iglesias et al. (2014), a comparative study of the accessibility of three LMS, Moodle, ATutor, and Sakai, was conducted as regards the compliance of each system with ATAG 2.0 and each system’s user interface with WCAG 1.0. The results of the study indicate that indeed barriers to accessibility exist in each of the three systems evaluated. More to the point, the authors conclude that ATutor facilitates the creation of accessible learning content better than the other two LMS. However, problems were observed in all three LMS that would likely limit their accessibility for certain groups of users like elderly people and people with disabilities. Such accessibility barriers could partially or completely exclude these users from interacting with the LMS (Iglesias et al., 2014).

Regarding accessibility of mobile applications for LMS, a recent study showed that many educational mobile apps remain inaccessible to users with disabilities who require accessibility features such as talkback or screen reader features (Aljedaani et al., 2023; Brito & Dias, 2020). The authors in Aljedaani et al. (2023), Brito and Dias (2020) explore the accessibility status of the Blackboard mobile app, a well-known and widely used LMS. They have conducted a survey on students’ perceived usability of the Blackboard mobile app, where 1308 hearing students and 65 deaf and hard-of-hearing students participated. In addition, the authors collected and analyzed 15,478 user reviews from the Google Play Store to identify any accessibility issues. The outcome of this study was that most deaf and hard-of-hearing students found difficulty in using the Blackboard mobile app compared to hearing students. For example, the lack of captions in some videos caused problems for deaf students, as they could not hear what the teacher was saying and solely relied on captions. This problem was reported for both live-streaming content and pre-recorded videos. The app store analysis showed that only 31% of the reviews reported violations of accessibility principles that apps like Blackboard must comply with. The study highlights these violations and their corresponding implications to support LMS frameworks in becoming more inclusive for all users.

We aim to provide a complementary study by examining compliance with accessibility standards and key accessibility features regarding the 10 most widely used Learning Management Systems, a combination that no other work studied so far.
