Daughter is a 2nd Grade teacher. Uses MAC for emailing, facebooking, scheduling and research.
I’m not a teacher, but I don’t see how she can’t do all of that with the iPad. There has to be an app she can use to do the scheduling. If research is web searching she can do that on an iPad. Office will probably be out soon for it. I can do some basic Office functions with DocstoGo app.
