The
MathMol Hypermedia Textbook As
an educator one thing that constantly crosses my mind is the staggering cost of
textbooks. And perhaps, equally troublesome is the short life-time of most of
these books (especially those from K-12 schools). Somehow textbook companies always
seem to come out ahead of the game as US curriculum plans seem to be changing
every few years. Perhaps a change may be the in the making. The state of Maine
has just issued laptop computers to all their middle school students. Does this
signal a change from paper textbook to internet? Are we heading away from the
classical textbook and toward using the Internet as the prime source of information
for our students? We have already begun to see a greater acceptance toward online
research journals. Is the online textbook far behind? Online
K-12 Hypermedia Textbooks have several advantages over classic hardcopy books.
Perhaps the most significant being the ease with which an online book can be edited
and updated. Updating can easily be performed on an ongoing basis as new information
becomes available.
In addition, the Internet can make use of several multimedia tools that can provide
a more conducive learning environment for students. Among these tools:
- Javascript's
can be used to test students understanding as they proceed through a lesson.
- Java
applets can allow for real interactive activities.
- Flash
Movies put a different spin on the old saying "a picture is worth a
thousand words".
Because
the Internet contains so much public domain software, it is just a matter of time
before we see more Hypermedia Textbooks. I just hope that with all the accessible
public domain resources out there educational sites will remain 'free to the public'.
We
provide here an overview of a stunning example of a Hypermedia Textbook that makes
use of javascript, java applets and Flash animations. One of the applets Java
Mage makes use of input files that have been designed for K-12 use. Although we
exhibited some problems on loading of the applets (depending on Netscape and Internet
Explorer Browsers) most of the interactive activities worked once loaded. As Netscape
and Explorer become more in touch with user needs we expect compatibility of browsers
and applets to improve. What's

Example
of a Java Applet An
Interactive Java Applet (shown below --Java Mage) allows the user to measure distances
and angles as well as draw lines. Below the input file assists the student in
understanding basic concepts in 3-Geometry. To view the applet go to the MathMol

Animations Below
-- A Flash Animation From MathMol Textbook (Where's
the Math in MathMol) 
The
movie shows two particles of opposite charge attracted to each other. The relationship
between coulombic energy and distance is an inverse relationship. The coulombic
energy between the two particles varies with -1/r, where r is the distance separating
their center of masses. To view the animation you must go to the MathMol
site. |
