1) Write the learning targets and agendas for every class on the board. Drawbacks: Tiny writing, students can't see what I've written, no blank space on the board to use during instruction.
2) Only display one class at a time. Drawbacks: Some students still can't see, writing for every class is keeping me from supervising/managing my incoming and outgoing students during the passing period. Remember, I'm dealing with expensive instruments, cases, chairs, and music stands.
3) Install some more whiteboards in my room. Tried that, district took them down :-(
4) Give up and just not write it on the board. <--Not an option!
In my music room, my Surface Pro is continuously connected to my classroom projector wirelessly via its built-in Miracast wireless display connection. Now I can be standing at my classroom door with my Surface, not only monitoring my students, but also changing the agenda for my next class. Using OneNote makes the task fast and simple, and it keeps me organized(!).
But wait, there's more!
