The Physical Chemistry in Practice
DVD – A Multimedia Instructional
Supplement for Physical Chemistry
Gabriela C. Weaver
Purdue University
Goals of the Physical Chemistry in
Practice DVD
 Complement the very mathematical and
abstract nature of classroom PChem
instruction with real research applications
 Put PChem in relevant contexts
 Provide authentic data for student analysis
 Include visualizations of abstract or
microscopic concepts.
The Physical Chemistry in Practice DVD
 10 programs about current research
utilizing physical chemistry concepts
 The research projects have some
application that is tangible to students
 The modules include instruction on
modern instrumentation, data analysis,
and applications of the research
The Web-enhanced DVD Format
 DVD and HTML can be displayed in the same
viewing environment.
This is the current version of the HTML-based interface:
The DVD plays in the window and can be controlled through this
interface. Other content can also be displayed in this window,
depending on choices made by the user using the menu at the left.
The Web-enhanced DVD Format
 HTML page can initiate commands to the DVD
Video disc
 DVD video can initiate commands within an
HTML page
 Broadcast-quality video and audio
 **FULLSCREEN*** DVD video with no loss of
resolution (simple toggle switch control)
 Full HTML functionality (links, Flash, Java, etc.)
 Access to the “outside world”
 “Virtual Bandwidth” from “on-board” DVD video
Module Layout
 Background and Theory
 Video Movies
 Animations
 Interactive Problems
 Script (for videos)
 List of References
Background Theory: HTML-based
This is an
example from
the old
interface, but
the content in
the new
interface is
the same.
Video Movies
 All the DVD benefits:
 Broadcast-quality digital video
 MPEG-1 or MPEG-2 encoding, and VBR option
(variable bit rate encoding for more complex scenes)
 Dolby Digital or PCM Audio
(Pulse code modulation, same as CD-Audio)
 Multiple video or audio tracks: multi-language, multi-angle
 Multiple subgraphic tracks: graphic overlays, subtitles,
captions, simple animations, turn on/off
 Ubiquitous Playback
 Set top players, DVD computer drives, portable players
Video Movies
 Show science research in action,
being done and explained by the
scientists
 Interviews, laboratory procedures,
instruments
Video Example: The AFM in use
Animations
Example: the AFM up close

The PCIP DVD for teaching
 10 programs will cover full content of
traditional PChem curriculum
 Supplement lecture or lab
 in-class use by instructor
 private viewing by students on
computer or TV with DVD player
 Versatility of use
The Current State
 3 programs completed
 AFM/Semiconductor Growth (Stephen Leone, CUBoulder/Berkeley)
 SERS/Brain Amino Acids (Gerard Coté, TAMU)
 Solid-phase (polymer) kinetics and computer modeling
(Frances Houle, IBM-Almaden Research labs)
 2 additional programs taped (in editing phase)
 NMR/MRI (Jack Roberts, Caltech and Bill Bradley, UCSD
Medical Center)
 Hydrogen Fuel Cells (Sossina Haile, Caltech)
 Taping schedule for January ‘04
 Bose-Einstein Condensates (Eric Cornell, CU-Boulder)
 Additional programs on Schedule for ’04/’05
