Discussion on the practice of integrated teaching method based on Dewey’s educational theory in the teaching of standardized training of electrocardiogram / 中华医学教育探索杂志

ABSTRACT

Objective:To explore the application effect of comprehensive teaching based on Dewey's educational theory in the teaching of standardized training of electrocardiogram (ECG).Methods:A total of 60 residents who were accepted by the ECG Room of Linyi Central Hospital from January 2019 to December 2019 were randomly divided into control group and study group. The control group received regular teaching, and the research group received comprehensive teaching based on Dewey's educational theory, both of which received the standardized training for 3 months. The results of the two groups of ECG theoretical knowledge assessment, the diagnostic accuracy of various types of heart disease ECG performance, the clinical thinking ability before and after the training, the classroom participation after the training, the teamwork ability, the teacher-student communication ability, and the degree of recognition of teaching methods were observed as indexes. SPSS 22.0 was used for t test and chi-square test. Results:The basic knowledge, picture analysis, expanded questions and answers scores and total scores of the theoretical knowledge of ECG in the study group were higher than those in control group ( P<0.05), and the correct rates of diagnosis of ischemic cardiomyopathy, arrhythmia, atrioventricular hypertrophy and congenital heart disease were 96.67%, 100.00%, 96.67% and 100.00% respectively, which were higher than 73.33%, 80.00%, 70.00% and 66.67% respectively in the control group ( P<0.05). The systematic thinking ability, logical thinking ability, critical thinking ability, evidence-based thinking ability, network thinking ability, imaginative thinking ability, horizontal thinking ability and vertical thinking ability scores were increased in both groups after the training, of which the study group were higher than the control group ( P<0.05). After the training, the study group scored higher in class participation, teamwork ability, teacher-student communication ability, and teaching method recognition than the control group ( P<0.05). Conclusion:The application of comprehensive teaching based on Dewey's educational theory in the teaching of ECG standardized training can help residents master the knowledge of ECG theory and ECG performance of various types of heart diseases, and enhance their clinical thinking ability.
