Hi Nisa,
I appreciate that you emphasize the application of UDL within diverse backgrounds. This diversity can be seen through their different backgrounds whether it’s by culture, class, and etc..
Accessibility in Online learning environments is well explained. I agree that there should be “free or low-cost resources”. Giving the option to view the learning content through multiple devices provides the students a choice between cheaper alternative technology.
For ethical challenges, I will say that you could add into the concern of security. In which, students should be ensured that their personal data is secure and not open to the public.
Other than that, I appreciate that you use different formats to show information (video and images).
Good job on the blog post!
