The aim of this research was to explore (1) clinical years students' perceptions about radiology case-based learning within a computer supported collaborative learning (CSCL) setting, (2) an analysis of the collaborative learning process, and (3) the learning impact of collaborative work on the radiology cases.
The first part of this study focuses on a more detailed analysis of a survey study about CSCL based case-based learning, set up in the context of a broader radiology curriculum innovation. The second part centers on a qualitative and quantitative analysis of 52 online collaborative learning discussions from 5th year and nearly graduating medical students. The collaborative work was based on 26 radiology cases regarding musculoskeletal radiology.
The analysis of perceptions about collaborative learning on radiology cases reflects a rather neutral attitude that also does not differ significantly in students of different grade levels. Less advanced students are more positive about CSCL as compared to last year students. Outcome evaluation shows a significantly higher level of accuracy in identification of radiology key structures and in radiology diagnosis as well as in linking the radiological signs with available clinical information in nearly graduated students. No significant differences between different grade levels were found in accuracy of using medical terminology.
Students appreciate computer supported collaborative learning settings when tackling radiology case-based learning. Scripted computer supported collaborative learning groups proved to be useful for both 5th and 7th year students in view of developing components of their radiology diagnostic approaches.
本研究旨在探讨：(1)临床医学生在计算机支持的协作学习(CSCL)环境下对基于案例的放射学学习的看法；(2)协作学习过程的分析；以及(3)协作处理放射学案例对学习的影响。
本研究的第一部分重点对基于 CSCL 的基于案例的学习的调查研究进行更详细的分析，该研究是在更广泛的放射学课程创新背景下进行的。第二部分侧重于对 52 名来自五年级和即将毕业的医学生的在线协作学习讨论进行定性和定量分析。协作工作基于 26 个涉及肌肉骨骼放射学的放射学案例。
对基于案例的放射学协作学习的认知分析反映出一种相当中立的态度，不同年级的学生之间也没有明显差异。与去年的学生相比，较低年级的学生对 CSCL 的评价更为积极。结果评估显示，即将毕业的学生在识别放射学关键结构和放射诊断以及将放射征象与可用临床信息联系起来方面的准确性明显更高。在使用医学术语的准确性方面，不同年级之间没有发现显著差异。
学生在处理基于案例的放射学学习时欣赏计算机支持的协作学习环境。脚本化的计算机支持的协作学习小组被证明对五年级和七年级学生都有用，因为他们在发展放射学诊断方法的各个方面。
