One constructivist approach to assessing student learning is the use of portfolios. The contents of a portfolio demonstrate what a student knows and can do. The portfolio indicates actual products and processes a student has developed, as exemplified in the description of the contents of a student portfolio in a teaching methods course. Portfolios may also be used to extend the scope of the curriculum. The portfolio may be the major data course for a grade, but pride of ownership and achievement may motivate the student to learn more. A portfolio can be an important tool in linking course objectives, learning opportunities, and assessment procedures. (SLD)
