One way that universities assess teaching effectiveness is by eliciting student feedback. However, what standards do students themselves use to judge whether a lecturer is a 'good' teacher? As part of a study carried out at a Hong Kong university, students were interviewed about their first-year learning experience and asked what they felt constituted 'good' and 'bad' teaching. Unlike when asked to complete teacher effectiveness surveys, no criteria or characteristics were given. Responses focused primarily on teaching skills that supported student learning and encouraged critical thinking, particularly the teacher's ability to give clear explanations supported by relevant, practical examples.
