RESUMEN
Objective:To explore the application and effectiveness of online teaching in the teaching of medical imaging diagnostics.Methods:A total of 134 undergraduate students of Medical Imaging Technology Department of Chongqing Medical University in Batch 2016 and Batch 2017 were selected as the research objects. They were divided into control group and experimental group with 67 students in each group. The experimental group adopted the online teaching mode based on Xuexitong and Tencent Meeting learning platforms; while the control group adopted the traditional teaching mode. The final grades of two groups were compared, and self-made questionnaires were anonymously investigated, so as to realize the evaluation of online teaching effects. SPSS 21.0 was used for rank sum test.Results:The qualification rate of final results in the experimental group and control group were respectively 80.6% (54/67) and 64.2% (43/67). The qualification rate of final results in the experimental group students was significantly better than that of the control group ( P<0.05). A total of 134 survey questionnaires were distributed and all recovered. The survey questionnaires showed that experimental group was superior to the control group in self-learning ability, analyzing and solving problems ability, communication skills, interest and enthusiasm in learning ( P<0.05). Conclusion:The online teaching is conducive to improving the qualification rate of final results, self-learning ability, analyzing and solving problems ability, communication skills, interest and enthusiasm in learning for the teaching of medical imaging diagnostics, which has good teaching effects and qualities and is of great promotion significance.
RESUMEN
The development of medical imaging diagnosis technology has brought forward higher requirements for the teaching of oral and maxillofacial medical imaging diagnostics, In this study, we intro-duce the methods and concepts of comparative imaging to guide students to analyze and compare oral and maxillofacial diseases from different perspectives, and to promote the students' understanding of the disease image and mastery of disease diagnosis, improve the students' ability to choose the appropriate imaging method in the future clinical work. Comparative imaging is one of the important teaching methods in the diagnosis of oral and maxillofacial medical imaging, and it is also the direction of its future development.
