For this weeks blog I am going to examine another teaching methodology commonly used in Bangor University: Lectures.
Lecturing is the most popular methodology of teaching adults, used by universities worldwide to transfer knowledge and stimulate student thought (Bligh, 1998). Kowalski (1987, as cited in Bligh 1998) found that 73% of students felt the aim of lectures was primarily to transfer facts – but is this the main aim of education? – Do lectures actually satisfy the aims of education?
Charlton (2006) implies that lectures are an effective method of teaching students, suggesting that learning through direct speech is natural and encourages attention whilst enhancing how memorable the information is. A common argument against lectures is that they are ‘Spoon-feeding’ students, however Charlton (2006) addresses this by suggesting that it does not matter how students acquire knowledge, its more important that they know and understand it.
In relation to early learning theories, lectures could be seen as a product of the behaviourist learning theory. The behavioural theory has significantly impacted education, developing programmes, approaches and methodologies in teaching, such as lectures, which provide information from an expert, through structured guidance, a component of education that Dewey (1938) considers necessary. Although this methodology results in the development of knowledge, methods such as lectures generally do not result in high levels of engagement or in-depth perceptions of information (Austin, Orcutt & Rosso, 2001).
Michaelsen, Knight and Fink (2002) highlighted two major disadvantages that occur as a result of lectures, they suggested that students feel anomalous and are passive in lecture settings. To address this they promote the success of small group work indicating that participation and activities within a group eliminate both the feeling of anonymity and students passive behaviour, whilst ensuring students understand the applications of concepts rather that just knowing them. Carbone (1999) highlights a further disadvantage of lectures, implying that lectures generally have poorer attendance, more distractions and disruptive behaviour than smaller classes, thus indicating issues associated with lectures.
Many theories of learning such as that constructed by Thorndike (1927) describe the necessity of active learning within education, a concept which university lectures often ignore. But is there a way of making lectures more interactive? Huxham (2005) found that when ‘interactive windows’ involving debates, discussion and challenges were introduced into lectures, student evaluations found these to be the most preferred feature within the lecture. Therefore interactions could be added to enhance student involvement within lectures to enhance engagement and inspire critical analysis.
Overall I consider the evidence supporting lectures to be quite weak, as it only focuses on how to increase students knowledge of facts. Rather than endorsing in depth explanations, independent researching and true understanding of concepts, lectures provide students with information which they attempt to recall for exams – this is not learning, this is merely memorising information, and the education system should be based on more than this.
Vast amounts of evidence have suggested that small groups are more successful than lectures (Michaelsen, Knight & Fink, 2002) but despite this universities are still using lectures as a main method of learning. But why are they so stuck in their way? Research conducted by (Lake, 2001) compared 170 students performance and achievement perceptions of both lectures and group based teaching methods. They found that although students actually performed better in active group work condition, they perceived a higher sense of learning from the lecture condition. Thus indicating that students believe lectures to be better, therefore perhaps explaining why university’s still use them; as they are more preoccupied with giving students what they want, to ensure student satisfaction is high, rather than what is actually best for their learning.
Therefore I would conclude that lectures are not necessarily “the best teaching method” as suggested by Charlton (2006) they may be successful in spoon-feeding students but it does not endorse in-depth understanding or learning. Research indicates that small group work is a more successful method of teaching, although it has demonstrated that lectures could be enhanced by adding interaction such as questions or discussions. Perhaps the educational system, in particular universities, should focus on applying the best educational techniques rather than what the students want, find easiest or consider to be best technique merely to ensure satisfaction.
