Histology teaching in India and in other developing countries has not changed much over the past decades and has not joined the global movement of using virtual microscopy (VM). Many factors may have contributed to this academic inertia-including curricular requirements for traditional microscopy (TM) skills, assessments that are heavily based on TM, and unfamiliarity with modern technology among faculty, as well as infrastructural shortcomings. This study is aimed at overcoming these roadblocks by using a blended approach combining VM with TM in a tradition-centered curricular setting.
For validation of this approach, the authors conducted a non-randomized controlled trial with a crossover design on first year medical students at the Government Medical College, Thiruvananthapuram, India. Examination scores and responses of a student group taught with VM as an adjunct to TM were compared with a student group taught with TM only.
The test group had significantly better results when compared to the control group for knowledge-based tests ( = 0.012; analysis of co-variance) and for an unannounced visual-based test conducted 1 month later ( = 0.001; Mann-Whitney test). Feedback collected from students showed highly favorable responses to the use of VM for teaching histology.
This study should encourage Indian medical colleges and schools in other developing countries to start using VM as a supplementary approach for their histology education programs. Furthermore, as the Medical Council of India recommends the introduction of new competency-based integrated curriculum in India starting in 2019, the use of VM may facilitate more effective learning in the new scenario.

在过去几十年里,印度和其他发展中国家的组织学教学变化不大,尚未加入使用虚拟显微镜(VM)的全球潮流。许多因素可能导致了这种学术惰性,包括传统显微镜(TM)技能的课程要求、严重依赖TM的评估、教师对现代技术的不熟悉以及基础设施的不足。本研究旨在通过在以传统为中心的课程设置中采用VM与TM相结合的混合方法来克服这些障碍。
为了验证这种方法,作者在印度特里凡得琅政府医学院对一年级医学生进行了一项采用交叉设计的非随机对照试验。将以VM作为TM辅助手段进行教学的学生组的考试成绩和反馈,与仅接受TM教学的学生组进行比较。
与对照组相比,试验组在基于知识的测试中(协方差分析,=0.012)以及在1个月后进行的一次未宣布的基于视觉的测试中(曼-惠特尼检验,=0.001)取得了显著更好的成绩。从学生那里收集的反馈显示,他们对使用VM进行组织学教学的反应非常积极。
本研究应鼓励印度医学院以及其他发展中国家的学校开始将VM作为其组织学教育项目的补充方法。此外,由于印度医学委员会建议从2019年起在印度引入新的基于能力的综合课程,VM的使用可能会在新的情况下促进更有效的学习。
