Tracking and assessing practical chemistry skills development: practical skills portfolios

We present the evaluation of the student response to a novel form of practical assessment; the Practical Skills Portfolio (PSP).  The PSP is a concise record of a practical activity for the purposes of assessment, which prompts students to engage in reflective practice on laboratory skills, and provides opportunities for enhanced feedback delivered in a timely manner.  Key goals of this new approach are to assist students in assimilating the practical skills they are developing during their studies and to support them in developing their ability to write the different components of a full lab report.
