E-Learning environments are enhancing both their functionalities and the quality of the resources provided, thus simplifying the creation of learning ecologies adapted for students with disabilities. The number of students with disabilities enrolled in online courses is so small, and their impairments are so specific that it becomes difficult to quantify and identify which specific actions should be taken to support them. This work contributes to scientific literature with two key aspects: 1) It identifies which barriers these students encounter, and which tools they use to create learning ecologies adapted to their impairments; 2) It also presents the results from a case study in which 161 students with recognised disabilities evaluate the efficiency and ease of use of an online learning environment in higher education studies. The work presented in this paper highlights the need to provide multimedia elements with subtitles, text transcriptions, and the option to be downloadable and editable so that the student can adapt them to their needs and learning style. Los entornos de aprendizaje en línea están mejorando sus funcionalidades y la calidad de los recursos, facilitando que estudiantes con discapacidad puedan crear y adaptar sus propias ecologías de aprendizaje. Normalmente, el número de estudiantes con discapacidad matriculados es tan residual y sus discapacidades tan particulares, que resulta difícil identificar y cuantificar qué medidas de asistencia son relevantes para este colectivo en general. El objetivo de este trabajo es hacer entender cómo aprenden los estudiantes en entornos en línea dependiendo de su discapacidad y de las características del entorno. Consistentemente, se definen cinco ecologías de aprendizaje que son más frecuentes. Este trabajo contribuye a la literatura científica en dos aspectos fundamentales: 1) identificar qué barreras se encuentran, qué herramientas de apoyo utilizan los estudiantes online con discapacidad y cómo las combinan para formar ecologías de aprendizaje adaptadas a discapacidades específicas; 2) presentar los resultados en los que 161 estudiantes con discapacidad reconocida evalúan la eficiencia y facilidad de uso de un entorno de aprendizaje online en el ámbito universitario. Se resalta la necesidad de proveer elementos multimedia con subtítulos, transcripciones de texto, y la opción de que sean descargables y editables para que el estudiante pueda adaptarlos a sus necesidades y estilo de aprendizaje.

This article develops a methodology for the assessment of MOOC courses, focusing on the degree of accessibility of three Spanish MOOC platforms: UNED COMA, COLMENIA and Miriada X. Four different criteria have been used in this context: automatic tools, disability simulators, testing tools and educational content.

In this paper, we present the results of a research experience of implementing andragogy in a learning environment designed to better meet the needs of adult learners studying part-time at a distance university. The learning environment was composed of a learning experience on a formal distance university online course that has been enriched with a non-formal component based on students' participation in a Massive Online Open Course (MOOC) related to the same topic. The non-formal experience was designed to consolidate the learning of specific content that involved difficult concepts and foster collaborative skills. The university online course is in the field of computer science and human-computer interaction. The instructional design, including the course assignments, has been guided by Knowles' principles of andragogy. Results from the data analysis of five years of academic results and student satisfaction has helped to understand the learning experience from including a MOOC in adult distance formal learning.

Web Content Accessibility Guidelines (WCAG) have been the de facto standard for Web accessibility evaluation for more than two decades and therefore have been introduced into legislation and university curriculum in Computer Science. At The National Distance Education University (UNED) in Spain, we have been teaching the guidelines for the last 15 years but learning how to apply WCAG criteria is complex. In this paper, we present the results of the analysis of students’ performance in applying accessibility heuristic evaluation of an online resource (a Massive Open Online Course – MOOC) using WCAG. The experiment was carried out over two academic years to evaluate how accurate and easy it is to understand and use WCAG criteria by trained students as well as their perceptions of usefulness to evaluate accessibility barriers using automatic tools in combination with manual evaluation. Results from the study show that errors identified are aligned with accessibility evaluation literature: 65% of success criteria in WCAG do not reach 80% of agreement among raters which confirms the complexity of WCAG conformance. In total 62 (86%) criteria are marked as not being correctly addressed by automatic tools with an overlap of those showing false positives, and 25 criteria (34%) are indicated as difficult to evaluate manually. While all areas where raters disagree are potential opportunities for WCAG improvement, this research reinforces that WCAG evaluations are complex and difficult even with current automatic tools, and that the possible solutions for the way forward are: (1) a well-defined evaluation protocol including a combination of automatic tools and manual evaluations; (2) better training and professional development opportunities.
