Application of PBL and Situational Teaching Method Combined With RIS in Ultrasound Practice Teaching
Objective To evaluate the application value of problem-based teaching method,simulation teaching method combined with radiography information system in the undergraduate practice teaching of ultrasound medicine.Methods A total of 48 medical imaging undergraduate interns of Chongqing Medical University who practiced in University-Town Hospital of Chongqing Medical University from June 2020 to June 2022 were selected as the research subjects.They were randomly divided into the observation group(24 students)and the control group(24 students).The observation group was taught by PBL,situational teaching method combined with RIS,while the control group was taught by traditional teaching method.The two groups were compared in terms of performance,theoretical and operational skills,and questionnaire surveys after graduation.Results The experimental results of the observation group were(88.24±2.18)points in theory and(84.47±3.49)points in operation,which were higher than those in the control group,which were(74.48±2.32)points in theory and(71.33±3.24)points in operation.The satisfaction rate of the observation group was 95.83%,the control group was 79.17%.83.33%of students in the observation group believed that PBL teaching method+situational teaching+RIS stimulated learning interest,87.50%of students believed that clinical thinking ability was trained,91.67%of students believed that team collaboration ability was cultivated,83.330%of students believed that communication ability was improved,while 54.17%of students in the control group believed that traditional teaching stimulated learning interest,54.17%of students believed that clinical thinking ability was trained,45.83%of students believed that team collaboration ability was cultivated,and 50.00%of students believed that communication ability was improved.The observation group was significantly better than the control group in terms of learning interest,learning initiative,teamwork awareness,humanistic care awareness,communication ability,ability to retrieve literature,understanding of theoretical knowledge,mastery of skills and operations,and clinical thinking ability.Conclusion PBL,situational learning method combined with RIS system in ultrasound practice teaching not only help to improve professional quality of students,but also help to improve comprehensive quality of students,can improve teaching effect,and improve satisfaction with teaching of students.
