I agree wholeheartedly that the substance of the mathematics is the most
important part of the connection...just citing the connection in a list is
only an trite is up to the instructor and the student to explore
the connections as fully as possible ( including discard of the ones that
are tenous or trite). The key here is a matter of level of understanding,
and interest...when working with seventh or eighth graders, the simple
connection to cryptography may be enough to peak their they
become more interested, they will learn more to access the application and
to understand the connection. With college students, hopefully the
connections are explored more between earlier grades and
college, all sorts of variations of exploration occur.

Whoa!!! I know that this is a rhetorical question for all, but I will
answer it personally...regular class work is not a drudge in my class
hopefully ( I can only fantasize, project, and interpret student enthusiasm
dreamily!)...Moreover, the spicy stuff is sometimes vague, sometimes
not...Hopefully, I mix with discretion the amount of interconnection we are
able to address in class meaningfully...sometimes, the porridge is
hot...cold...just right...

Nope...I have been a "mathematician" and a "mathematics teacher" from the
age of 8...Seriously, I can relate to your mathematical evolution...

So why all the argument? We agree essentially--just don't assume that (1)
because I don't give an exegesis of every mathematical connection
I>mentioned on the list, that I don't understand the connections myself
or>that I don't have students explore these more concretely... or (2)
that>every student at every level must have our mathematical
"sophistication" in
order to benefit from interconnection...the first time that I saw
undergraduates connect the binomial distribution to Pascal's triangle to
combinatorics...(a straightforward connection), I was amazed at the
lightbulbs that started flashing...exactly the revelation you described in
your own evolution.

To list members: I apologize for the lengthy response that may not seem
most appropriate for list posting, but I am very concerned that we, as math
educators, make these interconnections in mathematics with our
students...we address connections in the Standards often as connection to
real life application...but what Ted and I seem to be dancing around is
that mathematics is a beautifully interconnected web...we want students to
become entangled with this web and explore it as much as possible...maybe
along the way, we will all learn some new math and how it is useful...
