The ethics form was signed off after three rounds of reviews.
The first revision, which was submitted after a group tutorial, took on board what was discussed in that tutorial (from the tutor and colleagues). Therefore, it clarified the writing and included a section on how my research could also benefit accessibility. The version also included further elaborations on the ethics of research (e.g., data storage).
The second revision further elaborated on how the proposed ARP relates to the specific action research cycle. After this revision, the ethics form was signed off.
