I am confused. In your discussion of fonts, you emphasize Times Roman but also include Arial and Helvetica. However, throughout the entire presentation, you use Arial exclusively. Personally, I prefer Arial as it is a cleaner typeface than Times Roman and is easier on the eyes. Have I missed something here?

I am fascinated by the inclusion of music into the classroom. The information in the section on music was informative, but is missing a basic ingredient: what music has been used in the past that has the most positive impact on students. I don't want to "plow old ground" when there must be instructors out there who have successfully integrated music into their presentations and know what works and, more importantly, what does NOT work.
