web growth - education

My son is in first grade.  Periodically he cleans out his desk, brings home a few weeks worth of paper, and dumps it somewhere at first opportunity.  If the trend continues, it will soon be his backpack being emptied and then his locker.  We'll get bigger and bigger stacks of paper - tons of unorganized data - very little information, context, or correlation.  But will it continue?   Thoughts on how schools could look if they embraced the web:

• Most work done electronically, stored, and indexed.  A web interface enables the student, teachers, and parents to search through this valuable repository of information.  When the student studies for her finals in math, she starts by querying for all problems that she got incorrect on her weekly math tests.  The teacher can request a composite statistical view of performance and trend lines in discrete subjects.  He can then drill down - find out how student A is doing with a certain trig or algebra concept - not just looking to see that the student got an 85 on the past few assignments, but seeing exactly which types of problems he's mastered, and which types he's not making progress on.
• As students do work online, they can submit it and get instant feedback.  The level of feedback is determined by the teacher depending on the assignment.  It could be as simple as correct or incorrect.  It could contain links to help the student find the answer, including online tutors, forums, etc.
• As students electronically submit long homework assignments - research reports, essays, etc., the teacher can review them in an RSS feed.  No need to wait for the next day to bring home a stack of 10 page essays from 20 students.  Less chance of the dog eating the essay the morning before the student has a chance to submit it.  The assignment wasn't submitted on time?  Auto email alert to the parents.   Perhaps the essay is submitted in a wiki - the teachers comments added directly in, rather than red scribble on a paper that is destined for a long stay at the bottom of a locker.
• Wikis in general could be used in many ways.  Ditto other online communication - blogs, photos, videos, etc.  How about students photo blogging or video blogging school events and sports?  Should book reports be done collaboratively - each student adding their take and creating an actual interactive conversation about the book?

Any of us could write 20 more bullet points, and take these bullet points another step or two.  Easier said than done - budgets, time, technology gap, different student access to computers and the web, etc.  But I guarantee if administrators, teachers, and parents focused on how to make this possible rather than the reasons it can't be done, then we'd get there, and I'm sure some schools are taking these steps.  If you know of any, please let us know via the comments.
