I am a university mathematics prof so far less of my time is devoted to teaching, but I still try and save it where I can.

For any class over 20 students I now use a tablet to lecture. I prepare notes in advance (using MS reader), save them and print them to pdf and then go back and erase the majority of material. I then make a pdf of the fill-in-the blanks notes for the students. These notes include figures, headings, tedious calculations and enough other info that the students have some idea what is going to happen. Many print out my skeleton notes and fill them in in class. But, there is not so much there that they mistakenly think they needn’t come to class. I bring a hard copy of the full notes for when I get lost while lecturing.

I must stress that I write out all my class notes. There is something about perfectly typeset mathematics that overly dehumanizes it for many students. Seeing me write it out and “do mathematics” in real time makes it much more approachable. This is one area where technology hinders rather than helps the student experience.

I often prepare too much for a given class but this can then but dragged to the next days class. I have also re-taught classes this way and it is easy to add things in or take them out.

MS Journal is barely sufficient but I am very sad having to use a PC. All in all this has turned out to be a boon to my time and I hear mostly positive reviews from the students.
