- BCA/iLRN is a powerful, integrated web-based homework, tutorial
and testing system providing self-help and diagnostic tools to enhance
your learning experience. An advantage this program has over WebAssign
is it is free! The version we will use is tied to ed. 6 of the text
(Physics for Scientists and Engineers with Modern Physics
by Serway and Jewett). Among the differences you will find with earlier
versions of the text will additional problems. The program is still
in the construction phase so it is by no means perfect. For example,
the system works best with WINDOWS Internet
1.2 or higher. You will also need Java 1.4.2 and some
applications may need Flash. Other system requirements can be found
on the iLrn web page.
While I have
not had any problems with Netscape, I am told the system will not
work properly with Netscape! There are several important aspects of
the program you need to know. First, you should know that if you do
not complete a problem correctly before you logout, you may see different
numerical values when you login in the next time! Second, you need
to submit the entire assignment at the end if you want your work to
be saved. Submitting individual problems does not save your assignment!
In situations where there are a limited number of times you can attempt
an assignment, a login counts even if you do not submit the assignment.
