SL and composition

Hello!

   I'm currently a graduate student in the MATW (masters in teaching
writing) program at HSU.  I teach one section of freshman composition,fall
semester being my first, and next semester I will attempt to incorporate
service learning into my course.  I will teach the the standard three-unit
course with the addition of one or two extra units that would help reflect
the community service component.  The extra units would be
project-dependent, reflectling the weekly time commitment.  I am curious if
anyone has done anything similar, and if so, has anyone run into any
problems evaluating the amount of work for units.

   I would also be curious if anyone who does integrate service learning as
an ongoing part of the semester curricullum for a freshman comp. course
would like to exchange any ideas...or offer friendly advice to someone who
has been criticized as overly ambitious.

   To my surprise, I have found a lot of published resources to aid in my
course design,  but perhaps the most valuable advice is what doesn't get
published.

   I'll give a more detailed description about my plans for the course to
those that are interested (I just deleted a paragraph that I realized may
be quite irrelevant to many and I will now stop blabbing).

Thank you
