Before we can even think about expounding
the term digital portfolio, the term portfolio must
be defined in detail. A portfolio is a purposeful collection of artifacts
that describe a student's progress in a class. There are several different
kinds of portfolios :
Project:
The purpose of this type of portfolio is to document the steps taken
along the way to a finished product.
Achievement:
These portfolios use quality recent work to assess the level of student
achievement at a certain point in time.
Celebration Portfolios:
Students decide which work they are most proud of to include in this
type of portfolio.
Growth: This
is the portfolio type that we will be most concerned with here. It's
purpose is to show progress toward specific learning targets. Through
the use of growth portfolios, document increasing levels of achievement.
In order to enhance learning, a growth
portfolio must be more than just a object, it must be a process. Included
in this process are several steps:
Choosing an entry
Receiving feedback
Reflecting
Using feedback to improve next entry
What is a blog?
Perhaps you have your students write
in a journal to record their learning in your classroom. Each day or
week you allow them to write about a current topic in math. The journals
detail their thoughts, reasoning, & troubles. Then you collect a
few, or all, of the journals and provide students (and yourself) with
feedback. You are often the only one to see them and to make comments.
Most likely, students use a composition book or notebook for their journals.
Now imagine that instead of having
your students write in a composition book, they keep a running record
of their learning on their own Web page. This online journal is updated
as often as they wish and, if required, the URL is available to every
student in the classroom so that they may make comments. The page is
also personalized--students have chosen a background color, font, and
given it a title. No bulky notebooks to drag around. This online journal
is known as a Web log,
or blog, and it is beneficial
in another way, it's free.
The main purpose of a blog is an online
journal. However, because of the editable templates, ability to hyperlink,
add images and audio, & comment on entries, blogs have evolved a
plethora of uses. Though not nearly exhaustive, the following is a list
of ways that blogs are being used in education:
posting class - related information
such as calendars, assignments, activities, and more.
posting prompts for writing
posting photos from class
online journals for students
learning logs
classroom newsletters
Portfolio +
Blog = Digital Portfolio
There are many definitions for digital
portfolio. In fact, the term digital portfolio is one of many different
names for what's also known as an electronic portfolio, ePortfolio,
& a webfolio (if stored on the web). The type of portfolio
I am speaking of on this site would be called a blogfolio.
Perhaps a proper defintion of digital portfolio is needed: the process
of archiving student work in an electronic format with the purpose of
enhancing learning. Unlike a traditional portfolio, where student work
may be placed in a folder, in a digital portfolio, student work is saved
to a computer hard-drive, a CD-ROM, or a somewhere on the web.
Blogs have many qualities that facilitate
the process needed to enhance learning and make them excellent repositories
for electronic student work. First, when a blogger posts an entry to
his/her blog, the date is entered
with the post. This makes it simple to order students entries chronologically.
Second, a comment link (included
with every entry) allows readers to give the blogger feedback about
their entry. After receiving this feedback, the blogger can then post
a reflection. This is powerful due to the fact that once posted, the
reflection will be a permanent part of the portfolio. Finally, all of
the entries that are posted to the blog show
up on one page making it easy to see the year's growth.
From the Classroom
My Experiment - Improving Scores on the State Test
In Ohio, there are many
questions on the state test that require a great deal of writing on
the mathematics portion. Questions such as these are referred to as
extended response items. These are typically the questions that students
struggle with the most on the state test. As a result, their test scores
suffer.
Obviously, the solution
to this problem is to have students write more in math. For the purpose
of improving test scores, teachers must focus on having students solve
problems and then explain the process involved. But this type of assignment
must be more than a token assignment thrown in once a month, or as a
word problem at the end of an exam; it must drive the mathematics instruction
in each and every classroom. For this reason, I decided to begin using
blogs as repositories for the extended responses that my students were
completing in class. That way, they could get all of the benefits mentioned
above and then I would be able to see if in fact their test scores actually
improved.
The Process
As I said above, a portfolio
must be seen as more of a process than an object. Care must be taken
to follow a certain set of steps. In my classroom, these are the steps
that make up the process:
Teach the material
that students must know in order to complete the extended response
entry. For example, a recent extended response question the students
were to solve was:
Mark's heart beats 16 times in 15 seconds. How
many times does it beat in one minute?
This question required students to know about derived
measurements. Therefore, the material I taught them
Assign the extended response
question and allow students time to solve it using the strategies
they have learned. I usually assign the extended response question
as homework so that they will be ready to post it the next day.
Post the blog entry.
Provide feedback.
I do this through the comments link on each entry. I use a rubric
(see
it here) that the students are familiar with before writing the
entry.
Students reflect. After students
have read the comments, they must then take the time to reflect on
them. What can they do to improve the next entry?
