Prior knowledge tests were carried out on undergraduates in a second year '
Principles of Ecology' course at Lincoln University, New Zealand. The same
test was repeated at the end of the course, helping to indicate how success
ful the course had been in improving students' knowledge. This identified s
trong and weak areas in the students' understanding of ecology, and clarifi
ed which parts of the course were being taught well, and which were not. Th
e use of prior knowledge tests, and the application of their findings, appe
ars to be rare at university level, but has great potential, especially at
a time when universities are under increasing scrutiny.
