I followed instructions and watched the videos for OneNote, and downloaded the software. At first, I had trouble just getting it to load on my computer. It took a fair amount of time, there were updates required, and I ended up restarting. It had installed itself without help from me, which is unusual for my computer, so it took a while to find it. I watched many more of the videos, and frankly, I was a bit bewildered by all the possibilities. It looks like there are a lot of neat things to use, but fairly complex and would definitely take some time to get used to. The video describes it as "intuitive", but perhaps that's for habitual users of Microsoft platforms, because it wasn't that way for me. I was able to find things by looking around, but it was very different than what I was used to using.
I started by creating a page for my band. I wanted to include a video for practice. I looked everywhere for an "embed video" link, menu item, etc. I couldn't find anything, and rewatching the tutorial videos just showed them embedding links for videos, not videos themselves. I searched online and didn't find much help, either. Then I tried putting in the link, and voila! The video automatically embedded. That would be a nice thing to note in their tutorials!
I made some other pages, and tried to insert files. I inserted a long pdf as a pdf printout, and it laid it out end to end. It would be nice to have the option to stack the pages, because it was a file of audition materials and that would avoid the tuba player having to scroll through everyone else's parts to find hers. When I inserted it as an attachment, there was just a link to click that opens it in Preview. My students use Chromebooks, so they would have to download it to open it.
I also went to make a table of my schedule, but was limited to only 8 blocks long. This doesn't help when your day has 9 periods plus lunch. It auto-populated the title to the last thing I added, which was a pdf of the yearly schedule. I don't know why it did that.
I also took a look at reviews of the program, so I could see how others liked or didn't like it. I saw many who rated it low, and said it was cumbersome, required downloads of lots of things, and didn't work well on non-Microsoft platforms.
Overall, my opinion of this software is not so great. My school uses Macs and Google, and we are all adept at using Google Drive and Gmail, which offers many of these same options without requiring downloads. Perhaps this has more features than Google's options, but the cumbersome nature of all of it and the learning curve don't make that worth my time. I don't want to make my students download more stuff and I am not even sure Chromebooks would allow that. Though I wish Google was a bit more streamlined with organization, I am going to stick with their products in my classroom.
