Schools are increasingly focused on ensuring that educational technologies are available to all students, including those with disabilities. To help with this mission, schools and other organizations are inviting software engineers to visit their classrooms to see first hand how the programs are used and how they can be improved to ensure accessibility. For example, they may discover that programs full of unlabeled pictures are totally useless to blind users who have no idea they’re there. It may sound like common sense, but often that is the missing link in the creation of affordable and effective educational software that is useful to all students.
