BIO181: General Biology for Biology Majors I
Current-Term Lecture Recordings



This is where I'll post recordings that I make when I lecture to you this term. Obviously, the recordings will not be available until after the respective class meetings have occurred. You may listen to these on their own, or you may follow along with the corresponding slide shows. Perhaps most useful are the synchronized slide shows, in which the slide shows are synchronized (in mp4 video format) to the audio of corresponding lectures that I recorded in a previous term. Those files and others are available on the Online Lectures and Slide Shows page. A separate link to that page appears in the menu on your section's page on the Hoffman Site.
