Motivation Need for ULM Specific Math Videos
(not generic) Desire to Offer Classes via Internet Need for Inexpensive Delivery Wanted Accessibility for Majority of
Students (not just distance learning students)
![Page 3: Presentation (PowerPoint)](https://reader035.vdocuments.site/reader035/viewer/2022070317/55652bb2d8b42a767f8b4dc5/html5/thumbnails/3.jpg)
Earlier Attempts Streaming Video (thought about it,
couldn’t afford it!) Initially Attempted Incorporation of
Web-Delivered PowerPoint with Videos .AVI and .WMV movie unstable when
loading to Blackboard

Attempts Direct .WMV problems
Video Quality Low and Large Video and Audio Machine Dependant
and Unstable
![Page 5: Presentation (PowerPoint)](https://reader035.vdocuments.site/reader035/viewer/2022070317/55652bb2d8b42a767f8b4dc5/html5/thumbnails/5.jpg)
Attempts (cont.) Importing from .AVI form to .WMV
Higher Quality and Much Smaller Size, as Little as 1/30 of Original .AVI Size
Original .avi Converted .wmv

What was produced Web (and CD) Delivered Window Movie Maker Clips of Class
Content Viewable from Internet Explorer
Browser When on CD, Internet Connection not
Needed

Making Video Even Smaller Long Videos
Small Single Problem Clips Reduce Download Time
Videos Made on White Board Glare from Board
and Character Bleed from Markers
![Page 8: Presentation (PowerPoint)](https://reader035.vdocuments.site/reader035/viewer/2022070317/55652bb2d8b42a767f8b4dc5/html5/thumbnails/8.jpg)
Making Video Even Smaller (cont.)
Small chalk board Eliminate Character Bleed and Some
Glare As Little as 1:30 Compression Rate
Camera Placed above Board Eliminates Camera Glare
![Page 9: Presentation (PowerPoint)](https://reader035.vdocuments.site/reader035/viewer/2022070317/55652bb2d8b42a767f8b4dc5/html5/thumbnails/9.jpg)
Making Video Even Smaller Quality of Original Video Does Not
Impact Size of Final .wmv File Low Quality .avi File about 250K/sec. with
Resulting .wmv File about 12.5K/sec. High Quality .avi File about 370K/sec.
with Resulting .wmv File from 12.5 to 13K/sec.
Not a Huge Sacrifice of Space for Greater Quality!

Procedure to Make Video
1. Video Made with Simple Web Camera in .AVI Format
2. Import Video into Windows Movie Maker
Edit and/or Merge with Windows Movie Maker
3. Save Clips into Window Movie Maker .WMV file
4. Place on Website
![Page 14: Presentation (PowerPoint)](https://reader035.vdocuments.site/reader035/viewer/2022070317/55652bb2d8b42a767f8b4dc5/html5/thumbnails/14.jpg)
To View (No Windows Movie Maker needed!) Must have IE (free) and Media Player (free)
Cost Students Nothing! Open IE, Go to Website Click Video, Automatically Opens in Media
Player Watching Videos
As much as student wants Pause Rewind Save to hard drive
Plug-ins Available for 95, 98, ME, XP, Macs and Supposedly Netscape
![Page 15: Presentation (PowerPoint)](https://reader035.vdocuments.site/reader035/viewer/2022070317/55652bb2d8b42a767f8b4dc5/html5/thumbnails/15.jpg)
Problems (and Solutions) Windows Movie Maker Only on
Windows ME and XP Solution: Upgrade Windows (approx.
$100) Only Need if You are Creating Videos
Students Without High Speed Still Have Problem with Download Time Solution: Create CD version
![Page 16: Presentation (PowerPoint)](https://reader035.vdocuments.site/reader035/viewer/2022070317/55652bb2d8b42a767f8b4dc5/html5/thumbnails/16.jpg)
Responses and Concerns IE Dependent
Netscape Developed Plug-in, But Have Had Trouble
Not Sure about Usage on Macs Download for Students is Slow if not on
Campus or Without Cable Modem or DSL
The Slower Your Machine the More Likely You are to Have Pauses in Video
Takes more Time to Convert and Upload than to Create

Conclusions Continued Response from
Students, Other Teachers, and General Public is Very Positive
Potential Uses Numerous Biggest Cost, for the Creator, is
Time Costs Students Nothing
