I think the previous posts have done a wonderful job of articulating the different types of and dimensions to portfolios. If I could add one more element to the discussion, it would be that students can develop a "keepsake" portfolio. Very similar to the ones described above, this type of portfolio is not standards driven, but rather represents what students felt made the particular class experience meaningful or relevant to their lives. The teacher asks students to select three to five work samples that constituted a sense of meaning to the student and a reflective component, consisting of questions such as why this work sample was chosen, how the students defined meaning in their learning, and how they see this conception changing over time. This particular portfolio's advantage lies in not being standard based, and reinforcing to students that they must assume the leadership of being active agents in their own learning and in the construction of meaning. I have seen this work with middle school and secondary school students. If modeled for younger students, I think it can be applied to them, also.
The previous answer was very informative. Now, are you talking about a student portfolio or a portfolio on yourself as a teacher, also known as a dossier? If that is the case, for a portfolio of your own work, you would collect samples of the student work like the previous answer stated, AND you would begin by first writing one page with your
a) CV or resume
b) Teaching philosophy
c) Areas of interest
d) Focal experiences (maybe your resume won't show your additional experiences in a project or volunteer work)
e) Explanation of the portfolio- what the reader is about to see
*A VERY useful 21st century tool for your own professional portfolio are wikispaces. Many of my graduate school teachers create free educator wikispaces to show these very things in webpages instead of paper. It is just an idea, but it will take you there.
There are many different ways to use portfolios in the classroom, and just as many different types of portfolios. You may use a portfolio as a collection of work by a student from the beginning of the teaching period to the end, in order to show growth of the student's writing ability. In a best-case scenario, the student will be able to look back at the earliest pieces and identify errors in usage and grammar that he/she was making and has now (after weeks, months of instruction and practice) learned to correct on his/her own with little or no direction from the teacher. Usually there are periodic reflections done--where the student asks him or herself questions such as: where am I now as a writer? How far have I come? What are my weaknesses and strengths as a writer? Where do I want to be as a writer in x-number of weeks/months? Progress is assessed by the number of errors or the frequency of errors which were made in the early writings as opposed to the student's ability to recognize and correct them in later writings. This portfolio should focus on the student's growth as a writer over time. This a working portfolio, and can be used for one year, or it can follow a student from grade to grade for several years.
You can also go with a process portfolio, which shows all facets or phases of a student's learning experience. This is a good choice if you need to show the overall learning process of a particular topic or unit. Items in the portfolio will show how students integrate specific knowledge or skills and the progress toward both basic and advanced mastery of the knowledge you, the teacher, want them to learn. You will probably include many journal entries from the students themselves about their learning process and how they are learning what they are expected to master--what has helped them, what hasn't, how do they know what they know, and what do they still need to learn? This portfolio focuses on the processes used by the student/teacher to ensure the student is learning the desired skills.
The showcase portfolio is best for summative evaluation of students' mastery of key curriculum outcomes. Unlike the working portfolio and the process portfolio which may include all a student's work, the showcase portfolio will have only a student's best pieces. These should be selected by both teacher and student choice. Only finished work is included. This portfolio may also include photos, videotapes, and electronic records of the student's work (flashdrive, webpages, recordable CD, etc.) This portfolio will also include written analysis and reflection by the student regarding the decision making process used to choose the works included in the portfolio.
There are many different types of portfolios, and each has a different purpose depending on what you, the teacher, hope to accomplish. Check out the links below for more information. Good Luck!
In response to Post #5, I would like to point to hassantauseef that though this is a very good question, he has put it up in the wrong place.
It is not a good practice to put up your question under a topic that does not relate to your question.
It would be best to put up this question as a discussion topic or a question in the business group.

A portfolio is an edited collection of work intended to showcase a creator's style or method of work. Typically, the work reflects a depth in one area of work.
A key component is the editing of the work. Regardless of the depth of a creator, the editing process allows for a clean, concise presentation to the intended audience.
The portfolio can be any number of assignments placed in a container for easy access. Grading will be more subjective on aesthetic qualities and subjective criteria.
