Re: [Phys-l] Textbooks vs multimedia



While recognizing the limitations of textbooks, I am not that harsh in my judgement as others in this list.
Maybe, because I personally know one author who spent years preparing his text, and this had serious repercussions on his health, and his family life.
I do not have the time or the inclination to "write extensive notes" to my students, as has ben suggested. On badly written chapters (the worst are chapters/sections about work and energy in Mechanics, and about potential in E & M) I just explain what needs to be done, and provide succint notes.
I include in tests, (for about 20-25% of the marks), questions that must be answered in words, diagrams and equations, rather than numbers. Invariably, the class average on these is worse than the numerical problems.
For 2nd and 3rd semester classes, I ask students to make a 10 minute presentation on some aspect of the course, or some technology related to what we do. These start about the 6th week. It takes away time from formal teaching, but it amounts to an oral test, when I can find out if the students really understand what they are talking about.
