Study on the cognition,learning habit and learning effect of Clinical Epidemiology among different types of postgraduates
Objective To investigate the cognition and learning habits of different types of postgraduates and evaluate learning effect and its potential risk factors on clinical epidemiology in a medical college,so as to provide relevant data for improving the teaching method and learning effect of clinical research methods for postgraduates.Methods A cross-sectional study design was conducted to enroll all the postgraduates of Grade 2020 in a military medical school.A self-filled questionnaire was adopted to collect data.The discrepancy of cognition and learning habits between different types of postgraduates was evaluated by univariate analysis.Discussion was conducted to clarify the potential risk factors of learning effect.t tests or Mann-Whitney U tests were conducted to test the differences between groups for continuous variables.Chi-squared tests or McNemar tests were applied to evaluate the difference between groups for categorical variables.Results A total of 652 postgraduate students were enrolled for analysis,including 409 master students(62.7)and 243 doctoral students(37.3).The proportion of doctoral students who have heard of clinical epidemiology(χ2=19.99,P<0.001),who have learned clinical epidemiology(χ2=9.20,P=0.002),who are interested in(χ2=11.41,P=0.001)and think the course is important(χ2=10.71,P=0.001),who previewed before class(χ2=11.21,P=0.001),reviewed after class(χ2=3.29,P=0.001)and actively discuss in class(χ2= 11.64,P=0.001)is significantly higher than that of master students,the difference was statistically significance.The average score of all the postgraduates was(5.50±1.62)points before teaching and(7.47±1.90)points after teaching,the difference was statistically significant(t=-23.49,P<0.001).After teaching,the grades of full-time students improved more than that of part-time graduate students,there was statistical significance in the master group(t=4.41,P<0.001),while not in the doctor group(t=0.94,P=0.351).Conclusions The mastery of key points on clinical epidemiology have significantly improved after teaching among the postgraduates of different types.Different teaching methods and processes should be adopted to the variety of postgraduates according to their knowledge foundations and shortcomings.Besides,standardizing their learning habits are of certain significance to improve the learning effect.
