Here are many links that describe portfolio assignments:
* Sometimes they're done for English classes (selections of the student's writing, not always what he/she considers the best; sometimes including prewriting examples, etc.; some from the beginning of the year, the middle of the year, the end of the year).
* Sometimes they're used for art classes (selections of a variety of a student's work or a specific series, depending on the assignment; portfolios are also often, or always, used for Advanced Placement art classes).
* Sometimes they're used in elementary grades to include a broad spectrum of what a student has learned throughout the year; sometimes including early work and later work for comparison purposes, so parents and teachers can see the progress a child has made during the year.
I think what yours is asking for is similar to one for an English assignment, but with much more direction. I'd take each element you have to include/cover and make a section about it, including write-ups and graphics. Inside your portfolio, you should set up divisions, one for each element you need to cover. Then within each division, include your information and graphics.
Here's what I think of when I imagine a portfolio like what you are to come up with:
Choose ONE of these, any color you want. Then put each division's information in a regular file folder inside the portfolio/pocket folder.
Does this help?
Thanks I will try that
