People learn differently. There are different theories about learning styles, but one of the more common break downs is visual, auditory, and kinesthetic.Because of the different learning styles, I try in my teaching to address as many of those styles as I can. Personally, I'm a visual ("read-write") learner, so if I go to a talk I really appreciate someone having Powerpoint running as well (as long, of course, as they don't read the slides verbatim!). In the same vein, to try and communicate with people who are auditory learners, I do lectures on topics in my classes as well as presenting written information. I'm afraid I don't really know how to teach abstract topics like IP addresses to kinesthetic learners, but I think labs are generally more helpful to those students than readings or lectures For all those reasons, for my Entertainment Control Systems class this year, I'm trying an experiment: recording the lectures and putting them online for the students to watch outside of class time. The time that we used to spend on lectures will now be used to expand the lab periods (which will also include time to clear up any questions from the lecture/reading).
I figured that as long as I'm spending the time to record the lectures, I might as well post them online here for anyone else interested. I will post them as I work through the course topics this semester, so they will likely come in out of order. If you have any comments, please let me know!
Also, if you're using the book to teach a class, please let me know and I can add you to an email list so we can discuss issues related to the material.
