OneNote Notebooks
"Often times i can't read my own hand writing, and one note helped A LOT because we could see what you did to solve an example and apply that."
Student Survey Response (20182019) "Being able to go back and see the homework solutions and the examples we did in class really helped to prepare for tests." Student Survey Response (20182019) "I liked how we had the opportunity to look back at practice problems we did in class, and see your work on how we were supposed to do it. Additionally, the representation of the different colors to do the problems was very beneficial..." Student Survey Response (20182019) "It was the best resource any teacher has used. For me, it was amazing to be able to get your notes when I missed days of school and also to be able to check all of my homework." Student Survey Response (20182019) "This was my first class using [OneNote] in and i really liked it. It helped me stay organized and i like looking at the notes online. I kept one note up every night while doing my homework to reference the notes we took during class. This helped me to understand the homework better because it gave me the opprotunity to see examples of how to do it. I also liked that we got to see your work rather then if we wrote it it may have been written differently. Overall, onenote was neat and made math easier to understand." Student Survey Response (20182019) "I liked the fact that I could check my homework and study my notes directly from my home computer or my phone on the go." Student Survey Response (20182019)
