Abstract
Objectives: Teaching of ECG interpretation frequently relies on visual schemas. However, subsequent student ECG interpretation skills are often poor. Expertise research shows that expert looking patterns frequently deviate from the steps taught in schema learning. The present study made a cardiology expert's gaze interpreting ECGs visible - through eye-tracking videos with cued retrospective reporting (CRR) - and investigated the potential as an additional expert-driven route to improve medical students' ECG interpretation skills.
Methods: N=91 Medical students participated in the RCT of an ECG e-learning session aimed at medical students' ECG interpretation skills gain, either receiving the newly developed eye-tracking video with CRR audio commentary materials (n=47) or studying via four clinical cases only (n=44). Three outcome scores relating to different aspects of ECG interpretation skills were derived from pre-post MCQ ECG tests. The effect of the EYE-ECG training and additional characteristics (e.g., prior experience, interest) on student ECG interpretation skills were evaluated using t-tests and multivariate linear regression.
Results: A small, non-significant advantage of the EYE-ECG training signifying a tendency for greater knowledge gain was observed, compared to training as usual. In multivariate regression models, the predictive value of clinical case 1 was an unexpected finding warranting further exploration.
Conclusion: Additional gains after an only 9-minute intervention using videos of expert's real-time gaze pattern in combination with hearing their thought processes during ECG interpretation is a promising finding. Furthermore, a number of specific performance characteristics enabling students to best benefit from ECG training were identified and possible modifications to the learning intervention suggested.
期刊介绍:
GMS Journal for Medical Education (GMS J Med Educ) – formerly GMS Zeitschrift für Medizinische Ausbildung – publishes scientific articles on all aspects of undergraduate and graduate education in medicine, dentistry, veterinary medicine, pharmacy and other health professions. Research and review articles, project reports, short communications as well as discussion papers and comments may be submitted. There is a special focus on empirical studies which are methodologically sound and lead to results that are relevant beyond the respective institution, profession or country. Please feel free to submit qualitative as well as quantitative studies. We especially welcome submissions by students. It is the mission of GMS Journal for Medical Education to contribute to furthering scientific knowledge in the German-speaking countries as well as internationally and thus to foster the improvement of teaching and learning and to build an evidence base for undergraduate and graduate education. To this end, the journal has set up an editorial board with international experts. All manuscripts submitted are subjected to a clearly structured peer review process. All articles are published bilingually in English and German and are available with unrestricted open access. Thus, GMS Journal for Medical Education is available to a broad international readership. GMS Journal for Medical Education is published as an unrestricted open access journal with at least four issues per year. In addition, special issues on current topics in medical education research are also published. Until 2015 the journal was published under its German name GMS Zeitschrift für Medizinische Ausbildung. By changing its name to GMS Journal for Medical Education, we wish to underline our international mission.
