RESUMO
Objective To explore the teaching effect of flipped classroom teaching mode supported by the 3D printing model in the embryology experiment. Methods Totally 76 students from class 2016 were randomly divided into two groups: the experimental group previewed the embryo 3D models before class and taught other students in class, while the control group did not preview the embryo 3D models before class. An embryo knowledge test and a questionnaire survey were carried out before and after the experimental class to compare the differences of knowledge mastery and self-evaluation between the two groups. Results In the aspect of self-evaluation, the self-evaluation of the experimental group students in explaining the causes and explaining the process of development was significantly improved after the lecture (P<0.05), while the self-evaluation of the control group students in identifying the structure, understanding knowledge, telling the causes and explaining the process of development was significantly improved (P< 0.05). In terms of knowledge test scores, the scores of students in the experimental group and the control group after teaching were higher than those before teaching (P < 0.05). The improvement of the knowledge test in the control group was significantly higher than that in the experimental group (P<0.05). The experiment group' s grades of knowledge test were significantly higher than the control group in the second experiment. 70.27% of the students thought that they were still lack of knowledge in the introspection of the causes of wrong answers. The misunderstanding of English nouns (15.54%), psychological factors (5.41%) and other factors (8.78%) also caused the students to lose points in the knowledge tests. Conclusion The combination of the 3D printing model and the flipped classroom teaching mode can effectively improve the teaching effect, which should be paid attention to in the reform of embryology experimental teaching.
RESUMO
Objective To provide references by analyzing the history, hotspot, and trend of the research in body donation. Methods CiteSpace software was used to conduct a co-occurrence network analysis. Totally 196 articles in CNKI database and 114 articles in Web of Science Core Collection Database were included. Results The number of articles in China increased in recent years. "Political and legal organizations" and "medical schools and departments" were main research institutions. "Death", "donation attitude", "ethics", and "humanity educations" were new emerging research directions in recent years. National studies of body donation were mainly conducted by USA and New Zealand, while most institutions were universities. High frequency keywords were "dissection", "cadaver", "anatomy" Conclusion Research in body donation in China shows a trend of increasing depth and diversity, while most research still lacks innovation and cooperation compared to national studies, especially studies in legislation and human ethics of body donation.
