Note: We recommend you view the streamed lectures through Coursera. If you download the lectures to your computer, you will lose the slide content.

Features of the Video Lectures

Many of the videos in this course display both the instructor's lecture and the slides the instructor is using during the lecture. Here's how to make these videos work for you.

The first illustration, below, shows the lecture filling most of the screen, with the instructor's current slide as a small inset in the lower right corner. The second illustration shows the opposite view: here the slide is large enough to read all the details, but the instructor is shown in a small inset. Click on the small inset to toggle between these two views.

Move forward or backward in the video by selecting a slide in the Slide Preview Bar.

Other controls allow you to select the playback speed of the video, adjust the volume, and use the Full Screen view (note, though, that you can't use the Slide Preview Bar in Full Screen view). Keyboard shortcuts are available, as well.

Video Downloads of Lectures

The University of Washington is committed to working with some of the world's leading instructors to provide high quality, free education, globally.

We have removed the ability to download course video from Coursera for a number of reasons:

1. Our video contains functionality which only works within the Coursera environment.  Downloading it to another platform, such as YouTube, prevents this from working as designed.
   
2. Our ability to bring you a free course means that we must protect its content so that it is viewed as intended, as a component of an instructionally coherent educational program in Coursera.

We apologize if this is an inconvenience for some students who would prefer more flexibility for viewing this free content.

We hope that you understand our need to maintain a quality standard and continue to enjoy the course
