 ouble clicking on one of the modules shown in the course web (right)
of the Interactive Lab Manual developed at the University
of California-San Diego brings up an outline, such as the one shown below.
The outline suggests one possible way to move through the module, but a
student can go directly to areas of special need or interest. For example,
a student might choose to review the nature of light by clicking on the
indicated icon. |
 |
 |
 he program gives students the option of learning more about how light
can behave either as a wave or as a particle. Clicking on the "next
page" arrow, in this case, leads to a discussion about the general
characteristics of waves. |
| he program incorporates videos and audio text to supplement images and
the printed text. Clicking on the surfer in this screen sets him into motion
as he rides the wave toward shore. |
 |
 esides presenting information, the ILM poses questions for students
to answer in their own Interactive Lab Journals. "Food for thought"
questions written on electronic sticky notes invite students to write answers
in their journals. Students also can cut and paste material from any module
directly into their journals, producing their own custom-designed notes. |
 |
 art of the spectrophotometry module is a "virtual spectrophotometer."
Turning the wavelength knob with the mouse causes the components within
the spectrophotometer to operate just as they would in the actual device,
but with the top removed so their functions can be seen. Students also can
calibrate the instrument and observe the impact that poor calibration has
on the absorbance measurement. Learning this helps them avoid similar problems
with real spectrophotometers. |
 |
 tudents following the spectrophotometry module may want to review how
to make dilutions. By clicking on the course web button and then on the
dilutions module, they can move to sample problems that provide written,
spoken, and visual explanations of each step. Clicking on the photograph
of program developer Gabriele Wienhausen provides a video explanation of
the technique. |
 |
 t any time, students can open the on-line dictionary through their toolbar
and get a definition of scientific words and phrases used in the Interactive
Lab Manual. Other buttons on the toolbar lead to the outline for the module,
to an extensive help section, or to the University of California's on-line
catalog. |
