The wide-scale adoption of massive open online courses (MOOCs) comes with learners that have variable needs. While MOOCs may be attracting a wide range of learners, there is a need to provide those learners with a means to evaluate what is working in MOOCs and what areas of learning design can be improved. While learners may have compliments and criticisms of course designs, there is a need to organize feedback from such a wide range of participants into a coherent and actionable structure. This chapter describes the YourMOOC4all project, which offers the possibility for any learner to freely judge and provide feedback on the design of MOOCs in accordance with how it meets learner needs and Universal Design for Learning (UDL) principles. This kind of user feedback can be of great value for the future development of MOOC platforms, courses, and associated educational resources. YourMOOC4all gathers valuable information directly from the learners themselves to improve aspects such as the educational quality, accessibility, and usability of the learning environment.
