Using a purposeful collection of student work and student reflection upon that work to stimulate critical thinking
A learning portfolio is a collection of student work samples (e.g., a three-ring binder, CD-ROM or web site) and some form of reflection by the student upon that work. As part of what some call "authentic" assessment (Sunstein, 2000), portfolios can give more robust evidence of student learning than can, say, a multiple-choice test. Recently, many have discovered that electronic platforms like Blackboard can be an efficient way for students and instructors to organize and exchange portfolio information, thereby limiting the back-and-forth exchange of clunky objects like three-ring binders and enabling collaboration portfolios (Liu, 2007).
Product portfolios are used for end-of-term evaluation with students choosing to showcase the best versions of the work samples required. After a class is finished, these can be used to show future employers the student’s specific capabilities and experiences in the subject, a feature which is particularly appealing to professional schools (e.g., business, journalism, architecture and education).
Process portfolios document a student's growth across the semester, and are often required to be turned in to the teacher several times during a semester, with the teacher reviewing the updated contents and returning them to the student. The process portfolio can become a place where the teacher has a private, written "conversation " with the student about their work and its progress, which can be a satisfying experience for both teachers and students. In their research, Rickards and Guilbal (2009) identified three continua along which students reflections upon their work unfold as a course elapses:
1. From concrete and narrow to complex and interpretive
2. From demonstrating an outcome to probing the meaning of an ability
3. From exploring their personal narrative in a field of study to seeing their future self in a wider context such as a professional and citizen
Fink (2003) developed a Taxonomy of Significant Learning Experiences, built upon the three main components of instructional design: learning goals, teaching and learning activities, and feedback and assessment methods. Each of these components is comprised of several elements, fair descriptions of which would be beyond the scope of this brief introduction. Important here is Fink's emphasis on the power of the learning portfolio to "integrate and promote all three of the main components of instructional design" (p.118).
Schulman (1998, pp.34-35) identified five virtues of portfolios and five dangers. First, the virtues:
However, Schulman also identified five dangers of portfolios which lead to the following warnings:
When a class uses portfolio assessment, students are told at the beginning of the semester what kinds of things to collect, in their portfolio and what to expect for evaluation of the portfolio. Some teachers let students pick a theme for the learning they are going to document with the portfolio, and many who teach inquiry classes use portfolio assessment because of the personalized nature of the portfolio. These teachers sometimes require students to fill out a learning contract to specify the details of their inquiry, and portfolios almost always contain some form of reflection assignment.
