During the past week, I have learned that there are different types of portfolios, created to serve difference purposes and audiences. Broadly, the two main types are
presentation portfolios and
working portfolios.
A presentation portfolio
is a showcase of collected works. Most of the writing portfolios available to the public on the internet seem to be presentation portfolios. Many were created by freelance journalists who are marketing their skills with persuasive "hire me" messages. When I create a presentation portfolio, I plan to include samples of my best work, selected to impress a specific audience. While I may add brief descriptions of individual artifacts to explain why I included them in the portfolio, the main function of my presentation portfolio will be to attract prospective employers.
In contrast, the most important reason for maintaining a working portfolio is to enhance learning. Essentially, a working portfolio is a tangible manifestation of the abstract theories of constructivism. According to constructivism theory,
"people construct their own understanding and knowledge of the world, through experiencing things and reflecting on those experiences" (from "
Constructivism as a Paradigm for Teaching and Learning," one of many sources on the topic). Meaningful, long-term knowledge isn't acquired by passively listening to a lecture and parroting back what was said. As learners, we need to be actively involved, integrating new information in our own way. That's where the working portfolio comes in. Students can use portfolios as a tool for learning, reflecting on their own understanding of who they are, what they know, and where they see themselves heading. Teachers, mentors, and homeschooling parents—all of us who aspire to become "guides alongside"—can use working portfolios to examine personal and professional goals, reflect on the learning process, and evaluate the effectiveness of different approaches.
