Measuring the quality of e‐learning

This paper shows how concept mapping can be used to measure the quality of e‐learning. Six volunteers (all of them 3rd‐year medical students) took part in a programme of e‐learning designed to teach the principles of magnetic resonance imaging (MRI). Their understanding of MRI was measured before and after the course by the use of concept mapping. The quality of change in individuals' maps was assessed using criteria developed to distinguish between meaningful and rote‐learning outcomes. Student maps were also scored for evidence of conceptual richness and understanding. Finally, each map was compared directly with the content of the electronic teaching material. The results show that many of the student misconceptions were put right in the course of their learning but that many of the key concepts introduced in the teaching were ignored (or sometimes learnt by rote) by the students. This was because the teaching material locked these new ideas in structures and terminology that precluded meaning‐making among non‐experts. Our data suggest that students' prior knowledge is a key determinant of meaningful learning. We suggest that this must be acknowledged if the design and use of electronic teaching material is also to be meaningful. Ultimately, measures of student learning are the only authentic indicators of the quality of teaching through technology.     

BLIND MARKING AND SEX BIAS IN STUDENT ASSESSMENT

Three studies are reported which investigated the existence of sex bias in the marking of undergraduate degrees. Study 1 failed to find any evidence that females were marked less extremely than males by second markers, as has been found in previous research. Study 2 found that marker disagreements were not resolved upwards more frequently for male candidates, again contradicting the results of some previous research. Study 3 failed to find any of the expected differences between an institution using blind marking and one using non‐blind procedures. In the light of this negative evidence and of the confusing picture presented by. previous research, it is concluded that there is little firm evidence for sex bias in marking. Despite this, it is likely that there will be increasing pressure to adopt blind marking in the future.     

Science at the Crossroads? The Decline of Science in Australian Higher Education

The Australian Government has stressed the important role universities play in producing knowledge workers to service the needs of the technology-driven new economy. The massification of Australian higher education from 1989 rapidly increased the stock of university-educated people in all disciplines. Although university science enrolments also grew, analysis reveals both that the growth rate has been considerably less than the sector average, and that there has been a serious decline in the number of students being trained in the enabling sciences: chemistry, mathematics and physics. Recent Government policies are unlikely to reverse this critical decline.
