Utility
of the PPT and MOV Files
Below
each lecture title on the Chem 125 Homepage there are links to two
alternative versions (ppt
and mov)
that can supplement the video recordings and the transcript that are
available from the Open
Yale Courses (OYC)
website.
Clicking
the PPT link below
a lecture title on the Chem 125 Homepage downloads a Powerpoint file for
study or video supplementation.
Using Powerpoint as a Study Aid
With the
ppt file one
can use Microsoft Powerpoint or a free powerpoint viewer to study a lecture at leisure, perhaps together with class notes or the OYC
transcript.
Using Powerpoint to Supplement
the OYC Video (or Audio)
A ppt
file can show
the entire Powerpoint screen with maximum resolution and true color to supplement the corresponding OYC video.
Each ppt file contains timing information
allowing it to run in a
separate window
synchronized with the OYC video, so one can see and hear the speaker and
view the Powerpoint screen simultaneously.
Users with
low-bandwidth web access may prefer to synchronize the ppt file with the OYC mp3 audio
file instead of a video file.
Using Quicktime to Avoid Platform Incompatibility
Clicking
the MOV link on
the Chem 125 Homepage launches a Quicktime version of
the Powerpoint show that provides two
advantages over the ppt options above:
(1) It avoids
possibile incompatibilities between the user's software
and what was used to create the ppt file (Powerpoint for Mac 2004, version 11.5.5).
(2) It includes the sound
track of the lecture and shows occasional demonstrations. It can be run alone or in
a second window
synchronized with the OYC video (in
which case the Quicktime sound track
should be muted by clicking the speaker icon in the lower left corner
of the Quicktime window).
On a computer with fully compatible software, a ppt file has three advantages over the mov alternative:
(1) It facilitates navigation
during study.
(2) It provides maximum resolution.
(3) The ppt file is typically ten times smaller than mov.
