In this video from the 2008-2009 academic year, Cypress College Mathematics Professor Karen Watson explains logarithms and works through solving them. This is a portion of a standard class, and was recorded by the college's Supplemental Instruction program to assist SI leaders. You can learn more about Mrs. Watson -- Cypress College's 2003 Teacher of the Year -- in this article: http://www.cypresscollege.edu/news/blog_201202.htm#KarenWatson.

Editor's note: We are sharing the full video because of its value to those who want to comprehend logarithms, in tribute to Mrs. Watson, and in hopes that her exemplary teaching will live on. If you want to gain the sense of the impact of this lesson, you can watch the first 3.5 minutes of the video and the final 2 minutes or so (pick up at the 14-minute mark). The progression of the students is amazing.
