When I am using schoology from my laptop, I love that I can create an announcement that is viewed as a banner along the top of my course. I also love how you can display content "inline" so it is visible without clicking on it.
These features do not work when a student is using an ipad. As an elementary EL teacher, I use as many images as possible for my students to be successful. This would make using schoology for my students more accessible.
