Distance education is a solution to expand medical imaging education to students who might not otherwise be able to obtain the education. It can be a mechanism to reduce the health care worker shortage in underserved areas. In some cases, distance education may be a disruptive technology, and might lower student performance. This study compares student scores in a cadaver anatomy course in the four cohorts preceding the implementation of distance education to the first three cohorts that took the course using a multiple campus design. The means and medians of the lecture exam average, the laboratory component score, and the final course score of the nondistance education cohorts were compared with those of the distance education cohorts using nonparametric statistical analysis. Scores in an anatomy course were compared by campus placement among the distance education cohorts, and the independent effect of distance education on the laboratory component, lecture examination average, and final course scores, while controlling for cumulative grade point average and site (originating/distant), was assessed. Students receiving the course in a nondistance education environment scored higher in the anatomy course than the students who took the course in a distance education environment. Students on the distant campus scored lower than students on the originating site. Distance education technology creates new opportunities for learning, but can be a disruptive technology. Programs seeking to implement distance education into their curriculum should do so with knowledge of the advantages and disadvantages.
远程教育是一种将医学成像教育扩展到那些原本可能无法获得该教育的学生的解决方案。它可以成为减少服务不足地区医护人员短缺的一种机制。在某些情况下,远程教育可能是一种颠覆性技术,并且可能会降低学生的成绩。本研究将实施远程教育之前的四个班级的尸体解剖课程学生成绩与采用多校区设计修读该课程的前三个班级的成绩进行了比较。使用非参数统计分析,将非远程教育班级的讲座考试平均分、实验部分得分和课程最终成绩的均值及中位数与远程教育班级的进行了比较。在远程教育班级中,按校区位置比较了解剖学课程的成绩,并评估了远程教育对实验部分、讲座考试平均分和课程最终成绩的独立影响,同时控制了累积平均绩点和地点(起始/远程)。在非远程教育环境中修读该课程的学生在解剖学课程中的得分高于在远程教育环境中修读该课程的学生。远程校区的学生得分低于起始校区的学生。远程教育技术创造了新的学习机会,但可能是一种颠覆性技术。寻求将远程教育纳入其课程的项目在这样做时应了解其优缺点。
