In a book, What’s the Use of Lectures?, Mr Donald Bligh notes that lectures have been compared to reading and independent study, projects, discussion and audio and video learning. None of the comparators have been shown to be more effective in transmitting information. In other words, reading and independent study are just as good as listening to a lecture. Video delivery of content is just as good as a live lecture. Numerous studies have not shown that lectures are better than any of the other forms of education, but the converse is also the case.In truth, lectures — at least, in the traditional form that is totally passive, without student engagement — are an ineffectual tool for promoting conceptual understanding, synthesis, analysis and application of knowledge. Despite the data and research, they remain the most widely used tool, especially in higher educational institutions.

What is the biggest obstacle to educational transformation? It is a combination of a number of factors, the biggest being inertia. Of the many reasons why it is difficult to effect change, let me deal with the four major hindrances frequently observed around the world.

FEAR, INERTIA AND SCEPTICISM

First is the fear of change. Faculty and teachers are apprehensive that other methods of instruction will be more difficult and time-consuming. So they carry on with the same modes even when they know that what they are doing is not working well and there are better options available that do not involve additional work.

It is interesting to note that many of these alternatives, such as those employed at Duke-NUS Graduate Medical School and other places, actually save time by reducing repetition and leveraging on existing resources. Effective programmes in physics and other courses have been conducted with no major increase in workload.

Forsaking lectures need not increase workloads. The trouble is that many faculties cannot conceive of students learning on their own, rather than only imbibing what they are taught by lecturers. This mindset is likely to be a major impediment to change.

The second factor is institutional inertia and scepticism to change. To a considerable degree, it is very easy to do what we always do, as no one will ask questions and there is no need to justify a change.

So it is very simple to just publish a course description and a syllabus, stating that the course will be taught through lectures. The students can only find out what the course consists of by attending the lecture, though they are provided with a bare list of topics, sans details. It is possible for the same course taught by different instructors to vary a lot.

Even examinations often do not describe the contents of the course. Yet, no one will ask questions to justify resorting to lectures. On the other hand, questions will be raised if changes are proposed.

LACK OF KNOWLEDGE, SUPPORT

The third factor is the lack of knowledge about educational research on the part of specialised faculty in universities and colleges where teaching is less rewarded than research.

For example, there was enormous scepticism when our Duke-NUS educational team Dr Robert Kamei and Dr Sandy Cook proposed that there be no live lectures. They were asked questions such as: “How can you teach without lectures?” and “How can you cover the topic?”

This reflects the lack of awareness that conventional methods are not very effective. It also shows the lack of knowledge about the significant amount of research that has been done on alternative and effective methods of instruction.

The fourth and most important factor in many cases is the lack of availability of support and resources to effect the change. Many resources that are different from what is used in traditional lectures, have to be developed. This requires time, energy and commitment.

Fortunately, in many areas, these resources are now readily available. They have to be organised and developed towards particular courses. It is vital to clarify goals and learning objectives. Examinations and assessment techniques have to be built, linking learning objectives, content and assessment, for the system to work.

I believe these hindrances can be overcome only when there is acknowledgment of what works and what does not. But for change to really happen, teaching and education need to be based on clear outcomes — and not only the number of hours spent on lectures or direct teaching.

This requires institutions to embrace an evidence-based approach to education and a reward system that incentivises effective and innovative education, as well as developing a robust education research culture.
