ABSTRACT

Objective To observe and evaluate the application of case-based learning in occupational health teaching of clinical medicine students.Methods Seven-year undergraduates majored in clinical medicine were selected as study subjects,divided into two groups,and received case-based learning(55 persons,story case for theory course,field case for experiment course)and traditional teaching(56 persons,theoretical instruction for theory course,instructional video for experiment course),respectively.T test and x2 test were used to analyze and compare students' after-school evaluation results and the questionnaire survey results of both groups respectively.Results The total score of the after-school evaluation[(11.84 ± 2.86) vs.(9.80 ± 3.39),t=-3.419],basic cognitive ability score[(4.80 ± 1.08) vs.(4.05 ± 1.43),t=-3.097] and analyzing ability score[(7.04 ±2.21) vs.(5.75 ± 2.59),t=-2.813] of students in the case-based learning group were significantly higher than those of the students in the traditional teaching group(P＜0.05).Questionnaire survey showed that the number and proportion of case teaching group of students held a positive attitude towards the teaching methods used in improving students' ability to analyze problems(x2=4.757),increasing study interest (x2=4.371),promoting knowledge mastery (x2=4.276) is higher than traditional teaching group (P＜0.05).Conclusion Case-based learning can inspire students' learning initiative,improve their creative ability to use knowledge,analyze and solve practical problems,so as to promote the course scores.
