Lecture Recordings

All lectures will be posted as MP3, so they will play on portable players. If you LEFT click on a link, the recording will play in the browser. If you want to save the recording on your computer, so you can load it onto a portable player, you must RIGHT click on the file to invoke a pop-up menu. Then choose 'Save Link As' (or a similar option, depending on your browser) to save the file to the location of your choice. BE SURE TO PAY ATTENTION TO WHERE YOU SAVE THE FILE, SO YOU CAN FIND IT AFTER IT DOWNLOADS. Explicit instructions are found here.

As you listen to the recordings, follow along with the corresponding slide show that I presented during the live lecture. Obviously, there will be no lecture recordings to choose from until I deliver the first lecture in class. After the course begins, the link to a lecture recording will appear within hours after the lecture is given in class. If it has been a day or more, and the link has still not appeared, please email me.
