I enjoyed reading your insights on Universal Design for Learning (UDL)! Your breakdown of its principles clearly shows why flexibility is key for inclusive education. The examples you provided, like allowing students to choose assignment formats or using interactive tools such as Kahoot, make learning environments genuinely responsive to diverse needs and align with what I believe, too.
I completely relate to your experience with the sideways PDFs. It gave me flashbacks to when I had to deal with careless formatting. It just makes assignments unnecessarily annoying to get started since it requires you to download a copy of the PDF and fix it yourself, which, if you could not do that, was immensely frustrating. As you mentioned, straightforward improvements such as user-friendly navigation, providing multiple content formats, captioned media, and ensuring compatibility across various devices make an enormous difference.
