put something useful on that computer

Put Something
Useful on Your Child's Computer!
A Workshop for Parents and other Adults who care about what kids see

1. Eye-Hand Coordination and video games

2. Social IQ and Daniel Goleman

3. Audio files (great speeches) and other mp3 files.

4. How to find educational podcasts

5. Just enough math

6. Tips about preparing for tests

7. The Purpose of Education and other poems

Steve McCrea is the first teacher in Florida to obtain permission to
distribute for educational use the fun podcast called "Geo Quiz"
from TheWorld.org and broadcasts from OnTheMedia.org (a weekly analysis
of the news).  His presentation puts podcasts in the hands of parents
(everyone gets at least one CD). You leave the workshop with an action
plan for more educational uses for the music player and computers in
your home.

His publications include Put Something Useful on That iPod!, The GET
AHEAD Book, Adventures with Skype, Visual and Active SAT Prep, and other
educational DVDs. He maintains MathForArtists.com, VisualAndActive.com,
a test prep web site called TeachersToTeachers.com and
WhyWaitForDetroit.com (an electric car site).

What is mp3?  The Motion Pictures Experts Group MPEG came up with
various types of compression.  Mp layer 3 (yes, there are mp1 and mp2)
compresses 12 hours of audio into one. 

MP3 (MPEG-1 Audio Layer-3) is a standard technology and format for
compressing a sound sequence into a very small file (about one-twelfth
the size of the original file) while preserving the original level of
sound quality when it is played. MP3 files (identified with the file
name suffix of ".mp3") are available for downloading from a number of
Web sites. Many Windows users will find that they have a player built
into their operating system. Otherwise, you can download a player from
one of several popular MP3 sites. MP3 files are usually
download-and-play files rather than streaming sound files that you
link-and-listen-to with RealPlayer and similar products (However,
streaming MP3 is possible.)

To create an MP3 file, you use a program called a ripper to get a
selection from a CD onto your hard disk and another program called an
encoder to convert the selection to an MP3 file. Most people, however,
simply download MP3s from someone else and play them.

digital audio is typically created by taking 16 binary digit samples a
second of the analog signal. Since this signal is typically spread out
over a spectrum of 44.1 thousand cycles per second (kHz), this means
that one second of CD quality sound requires 1.4 million bits of data.
Using their knowledge of how people actually perceive sound, the
developers of MP3 devised a compression algorithm that reduces data
about sound that most listeners can not perceive. MP3 is currently the
most powerful algorithm in a series of audio encoding standards
developed under the sponsorship of the Motion Picture Experts Group
(MPEG) and formalized by the International Organization for
Standardization (ISO).
