Educational research suggests that cognitive processing in diagnostic radiology requires a solid foundation in the basic sciences and knowledge of the radiological changes associated with disease. Although it is generally assumed that dental students must acquire both sets of knowledge, little is known about the most effective way to teach them. Currently, the basic and clinical sciences are taught separately. This study was conducted to compare the diagnostic accuracy of students when taught basic sciences segregated or integrated with clinical features. Predoctoral dental students (n=51) were taught four confusable intrabony abnormalities using basic science descriptions integrated with the radiographic features or taught segregated from the radiographic features. The students were tested with diagnostic images, and memory tests were performed immediately after learning and one week later. On immediate and delayed testing, participants in the integrated basic science group outperformed those from the segregated group. A main effect of learning condition was found to be significant (p<0.05). The results of this study support the critical role of integrating biomedical knowledge in diagnostic radiology and shows that teaching basic sciences integrated with clinical features produces higher diagnostic accuracy in novices than teaching basic sciences segregated from clinical features.
教育研究表明,诊断放射学中的认知处理需要扎实的基础科学知识和与疾病相关的放射学变化知识。尽管人们普遍认为牙科学生必须掌握这两方面的知识,但对于教授他们的最有效方法知之甚少。目前,基础科学和临床科学是分开教授的。本研究旨在比较基础科学与临床特征相结合或分离教授时学生的诊断准确性。 51 名牙科学前学生(n=51)使用基础科学描述与放射学特征相结合或与放射学特征分离教授的方法教授四种易混淆的骨内异常。学生用诊断图像进行测试,并在学习后立即和一周后进行记忆测试。在即时和延迟测试中,整合基础科学组的参与者表现优于分离组的参与者。学习条件的主要效果被发现具有统计学意义(p<0.05)。本研究的结果支持在诊断放射学中整合生物医学知识的关键作用,并表明与将基础科学与临床特征分离教授相比,教授基础科学与临床特征相结合可提高新手的诊断准确性。
