A tool for long-term, ongoing, authentic evaluation. Also, some standardization of content should occur Collaboration should be encouraged Examples of portfolios should be provided Mentors should be provided Pack-ratting should be discouraged. The area of most interest in this study was teaching effectiveness. The study compared the ratings made by the different raters. Also, Centra compared the ratings on teaching effectiveness with end of the course student evaluations.
Results indicate that all three groups of raters judged the portfolios very high.
However, the three groups of raters differed significantly when rating teaching effectiveness. The deans gave the lowest ratings for total teaching effectiveness. Peer A gave the highest ratings for teaching effectiveness. The ratings of Peer A did not significantly correlate with any student evaluation measure. Considering that request were made for only positive portfolio content, Centra is not surprised that the ratings were generally high.
