Recommendations for Integration:
RWLO can be used either as a computer lab activity or assigned for homework
(see Backup below) to provide an opportunity
for students to assess real world network performance using the ping
and tracert utilities.
It is recommended that each student work individually to develop the
data, while collaborating with others in the class to solve logistic or
data interpretation issues.
Before assigning this
activity to your class, you should follow the Lab
Handout procedures in situ to
assure that your classroom internet connection and workstation security
setup will support the procedures as written. You should also prepare to project
the graphics Network, packet, Start, Command Window, ping, ping
result, tracert and, if desired, set
up the instructor workstation to project a real-time demonstration of ping
and tracert as needed.
Note that an optional follow-up activity and
handout is outlined in the Supplementary Resources section and
may be assigned as homework if desired. This would require a second class
session devoted to completing the supplemental activity.
If you opt to omit the
follow-up activity, it might nonetheless be useful to demonstrate an
Internet Weather Report such as http://weather.uci.edu. Point out to the class that the data
used is identical to that shown by ping, and is automatically updated
(using ping) about once every ten minutes.
Limited Internet access: If no
Internet access at all in classroom, use graphics Network, packet, Start, Command Window, ping, ping
result, tracert to introduce topic
and demonstrate procedure.
Group students as described in Supplementary Resources (grouping), distribute printed materials Lab Handout, LAB
RESULTS, and SLIDES. Have groups collaborate so each
member uses a library, computer lab, or home internet connection to develop
data. A follow-up session in a
subsequent class should be devoted to having groups collaborate to develop
one set of results to hand in and present briefly to class.
Limited number of computers in classroom, group students so each group uses one
computer. Have students rotate
to develop data for the exercise.
Students on each team may also be asked to take on roles such as “record
data”, “perform test(s)” etc.
