Screencasts and other Online Lectures
Lectures and Screencasts
Screencasts (video and audio podcasts) replace class lectures. The lectures were recorded by Prof. Dan
Suthers based on his lecture note web pages that are now listed as the "Topic Notes"
(Notes/Topic-01.html, etc.), which we also call the "web notes".
- The screencasts are available on YouTube.
- The screencasts focus on the most important points from the web notes and textbook, but do not
go into all of the details: you will still need to read the notes and/or the textbook for
some details. Rather, the screencasts present the most important aspects.
- The screencasts generally follow the same content and organization of the web notes, but Prof. Suthers did
not use the web notes directly in the screencast except where they save a lot of time in
generating the screencast. They were generated using a screen drawing program (UltimatePen),
a Wacom tablet display, and a mixture of images from the lecture notes and my own
handwriting. (Prof. Suthers also put in some of my photographs from around Hawai`i to make it more
interesting.)
- What would have been a one hour-long lecture on each topic is split into 3-4 screencasts
averaging about 15 minutes each, so you can pick and review the parts you need the most.
- If you are using these screencasts in a class taught by another instructor, be sure to pay
attention to what that instructor emphasizes, as it may differ from the content of the
screencasts.
Since the screencasts follow the web note content and organization, the web notes essentially are
a more nicely formatted version of what you see me write out by hand in the screencasts. One
strategy is to first view the screencasts to get an introduction, and then look over the web notes
and the textbook for more detail. Another strategy that students tell me that they have used is to
view them side-by-side, following through the web notes while watching the screencast.
All of the screencasts are available for download in Laulima (be aware they may be taking up disk
space in your download folder if you use this format), and all screencasts except Topic 1 can
streamed in YouTube without download. (We also used ITunesU, but it has been discontinued.).
They are of resolution 800x600 because this is the resolution of the Wacom tablet and it is
sufficient for the kinds of drawings and math we are using.Prof. Suthers recommends watching them at this
resolution rather than full screen.
When Prof. Suthers began this series he was still figuring out the technology. Audio has many problems in the
first few weeks, but it improves over time.
MIT Online Lectures
Online lectures are also available from the textbook authors. These lectures were recorded in an
MIT classroom in 2005, and also broadcast to Singapore. They are chalk-on-whiteboard lectures, but
some of you may prefer this style of lecture. Just be aware that they are based on the second
edition of the book, and the authors emphasize different aspects of their book.
Prof. Suthers found the same lectures on three sites (and there are surely
more). My preference would be for the VideoLectures.net version, but
your choice depends on your situation and preferences.
VideoLectures.net
http://videolectures.net/mit6046jf05_introduction_algorithms/
- - Audio is a little muffled
- - Not Subtitled
- + Powerpoint slides in parallel summarizing what is hand
written on the board
- + Topical index to jump to segments of video
MIT Open Courseware Site
http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-046j-introduction-to-algorithms-sma-5503-fall-2005/video-lectures/
- + Better audio
- + CC Subtitled (can turn on and off)
- + Has full text transcript
- - NO slides (you must read handwritten chalk in fuzzy video)
- - NO topical index
iTunes
http://itunes.apple.com/us/course/introduction-to-algorithms/id495066198
- - No metadata, no slides, just video.
- + Main advantage is you can download to play on your iPad or
iPhone.
