Transforming a medical curriculum development into an education research.

To the editor

As family medicine educators and researchers in China, it was with a great anticipation we read the article of curriculum development framework by Jill Schneiderhan and Dobson.1 Because education of future general practitioner in China has become increasingly important, this paper is timely and instructive. However, an elaborate curriculum development isn’t sufficient to become an education research. We hope to raise some concerns for the education researchers regarding the methodological aspects while developing a curriculum.

It seems that some authors view education research as a ‘soft’ science, therefore conducting the research without adequate rigour and precision. A systematic review2 of experimental studies in medical education demonstrated generally poor quality with inexplicit study design statement, lack of comparison group and institutional review board approval. Another scoping review3 of education researches in family medicine also highlights an overall need for increased sophistication in methodological approaches; 23% of the quantitative studies used pretests/post-tests, nearly half employed surveys as their primary method of data collection and only 10% used a randomised controlled trial. Taking the ubiquitous single-group pretests/post-tests designs as an example, pretest will influence performance on an identical post-test through familiarity with the questions. Likewise, without a concurrent control group, positive result of such educational experiment doesn’t signify the effectiveness of novel education intervention, as people spend time learning, they will receive higher scores on the post-training test. It also cannot justify the effectiveness compared with other existing teachings, therefore does little to inform educational practice. Such design is susceptible to numerous validity threats and has limited generalisability and application.4 Cook and Beckman4 also summarised other important yet often neglected issues in designing educational research.

As the field of medical education in family practice grows dramatically and the evolution from opinion-based teaching to evidence-based teaching, research in medical education matters with the premise of rigorous methodology.5 The perspective of education research should be changed from ‘soft’ to ‘hard’ science. We suggest the novice to follow the five steps proposed by William Ventres6 to start your education research, carefully design your investigation by obeying the evaluating guidelines7 from British Medical Journal or appraise your methodological quality by applying some valid scales, such as the Medical Education Research Study Quality Instrument.8 It would also be beneficial for the first-time researchers to attend some programmes that designed to build capacity for medical education research.9 Another convenient method could be the better engagement of methodologists throughout the research process.

Methodological aspects should be embedded in medical curriculum development with the simultaneous purpose of conducting education research. Paying more attention to methodology will bring better quality and combination of art and science in medical education.
