Student portfolios take many forms, as discussed below, so it is not easy to describe them. A portfolio is not the pile of student work that accumulates over a semester or year. Rather, a portfolio contains a purposefully selected subset of student work. "Purposefully" selecting student work means deciding what type of story you want the portfolio to tell. Portfolio would likely contain samples that best exemplify the student's current ability to apply relevant knowledge and skills. All decisions about a portfolio assignment begin with the type of story or purpose for the portfolio. The particular purpose(s) served, the number and type of items included, the process for selecting the items to be included, how and whether students respond to the items selected, and other decisions vary from portfolio to portfolio and serve to define what each portfolio looks like. I will describe many of the purposes and characteristics in the sections below. Student portfolios have most commonly been associated with collections of artwork and, to a lesser extent, collections of writing. Students in these disciplines are performing authentic tasks which capture meaningful application of knowledge and skills. Their portfolios often tell compelling stories of the growth of the students' talents and showcase their skills through a collection of authentic performances. Educators are expanding this story-telling to other disciplines such as physical education, mathematics and the social sciences to capture the variety of demonstrations of meaningful application from students within these disciplines.
Review Bloom’s Taxonomy to write three different levels of learning objectives for a subject you teach and determine which assessment would be most appropriate for each learning objective. Explain your reasons for selecting the assessment for each objective.
