Stereotypes of Gender roles, absence from scenes , gender-biased language, By country or region Australia A recent study of student evaluations of teaching (SET) from a large public university in Sydney focused on gender and cultural bias. The dataset of more than 523,000 individual student surveys across 5 different faculties spanned a seven year period 2010-2016. There were 2,392 unique courses and 3,123 individual teachers in the dataset. The researchers concluded, "We detected statistically significant bias against women and staff with non-English language backgrounds, although these effects do not appear in every faculty. Our findings on the effect of cultural background is novel and significant because in Australia, where the population is culturally diverse, current policy and administrative actions have focussed on addressing gender bias, but less on cultural or racial bias. We found some evidence that the proportion of women or staff with non-English language backgrounds in a faculty may be negatively correlated with bias, i.e., having a diverse teaching staff population may reduce bias. We also found that due to the magnitude of these potential biases, the SET scores are likely to be flawed as a measure of teaching performance. Finally, we found no evidence that student’s unconscious bias changes with the level of their degree program."
