Power BI is included in your Office 365 school license, but it doesn't automatically show up in the waffle of apps. After you login, it will :-)
Play around with it, and you'll start to see just how valuable a tool it is. I've used it to analyze my student's performance scores, reading comprehension scores, and recently their instrument checkout frequency.
I use an Office Form to track my students' instrument checkouts (I'll write about how I was able to capture it in the future), and it's now a daily routine in my classroom. This is one of the best parts though. Sharing my reports with my students for their own personal reflection on their learning.
People have been requesting an Office Mix on how I use Power BI, so I made one. It covers the basics for now, and more Mixes will be created in the future to go over other tips and tricks.
Also, gotta say that creating this Mix on my Surface was a piece of cake. #OnceYouGoPen...
