I love webquests, but agree that they need to be modified for
  individual classes or our standards.  The ones that
  currently exist give a great starting point for teachers to use
  as they design their own.  Perhaps we could divide and
  conquer across the district by assigning specific topics to
  schools and they would create webquests for SUSD that could be
  loaded onto a wiki or some other networking homepage.  If we
  started with 5th grade and then worked down as more computers are
  deployed (fingers crossed), then we would have things ready to
  go! 
  At our school we have struggled with some connectivity issues and
  had to make adjustments.  Some of our classes are using
  spreadsheets to create semantic organizers around topics, the
  kids use the internet to research all areas of a topic
  placed in the organizer, then select a specific topic to research
  in greater depth.  They create a product, such as a
  powerpoint or brochure and present the product to their
  class or other audience.  For example, I created a semantic
  organizer about the planets of the Solar System - along one axis
  are the names of each planet.  Along the other axis are the
  specific pieces of information students must research about each
  planet (ie., meaning/orgin of name, distance from the Sun,
  atmospheric content, etc.).  All students fill out the
  organizer completely using resources on the internet and
  then select the planet that they find most interesting to
  research deeper.  This means that they have made an informed
  choice to self direct their learning.  The teacher provides
  a rubric for their completed "product" and presentation, giving
  them guidelines for their efforts.  Once students know how
  to fill in the organizer the same "routine" can be used to
  whet their appetite before any deeper study.  You can
  give them a semantic organizer for Civil Rights leaders and after
  learning a little bit about all of the ones you want them to,
  students get to select one to focus on and become an
  expert! 
  The kids really like it and now the teacher is free to work with
  small groups instead of focusing on whole group, direct
  instruction the entire Literacy block.  The kids know the
  expectations and are excited to direct their learning (within
  limits a standard), while the teacher is focused
  on teaching the specific reading skills that individual or
  small groups of students need.
