Practical knowledge and skills of microscopy has classically been delivered for medical students using conventional microscopes (CMs). Using virtual microscopy (VM) in teaching practical histology was established during distance learning for Taif medical students during COVID 19 pandemic period. However, the suitable assessment methods for student performance during distance learning are still debatable. We focused on how to ensure the learner's achievement of course practical outcomes and learning domain.
This study aimed to ascertain whether using VM to evaluate student learning in practical Histology during distance education programs and if moving to VM affecting students' scores.
For the first time, we used VM during online objective structural practical examination (OSPE) of 3 year medical students. Different sets of virtual slides were given for students at the time of assessment, then different tasks were described and each student was asked to finalize his/her task during the designed time. A specific rubric was designed for the evaluation of student work. Moreover, student perceptions of VM as teaching and assessment method were assessed using online survey. Post examination psychometric analysis of VM OSPE was done and compared with previous OSPE results of the same batch of students.
The average student score was 4.63 ± 0.51 with no significant difference from previous student's scores. The net students' feedback was positive. Their average satisfaction on all items ranged from 3.7 to 4.25 on Likert scale. Students recorded the easy image access at any time and place with VM as the most distinctive feature.
Our results indicated that VM is not only an effective method in teaching histology but also it is an assessment method for measuring student performance during online assessment.
传统上,医学学生通过使用传统显微镜(CMs)来传授显微镜检查的实践知识和技能。在新冠疫情期间,针对塔伊夫医学院的学生进行远程学习时,虚拟显微镜(VM)被应用于组织学实践教学中。然而,远程学习期间学生表现的合适评估方法仍存在争议。我们关注的是如何确保学习者实现课程实践成果和学习领域目标。
本研究旨在确定在远程教育项目中使用虚拟显微镜评估学生在组织学实践中的学习情况,以及转向虚拟显微镜是否会影响学生成绩。
我们首次在三年制医学生的在线客观结构化实践考试(OSPE)中使用了虚拟显微镜。在评估时为学生提供不同组的虚拟切片,然后描述不同任务,要求每个学生在规定时间内完成任务。设计了一个特定的评分标准来评估学生的作业。此外,通过在线调查评估学生对虚拟显微镜作为教学和评估方法的看法。对虚拟显微镜OSPE进行考试后心理测量分析,并与同一批学生之前的OSPE结果进行比较。
学生平均成绩为4.63±0.51,与之前学生的成绩无显著差异。学生的总体反馈是积极的。他们在李克特量表上对所有项目的平均满意度在3.7至4.25之间。学生们认为虚拟显微镜最显著的特点是可以在任何时间和地点轻松获取图像。
我们的结果表明,虚拟显微镜不仅是组织学教学的有效方法,也是在线评估中衡量学生表现的一种评估方法。
