PRISM is a novel approach to support self-reflection and learning appraisal in dental students, based on a visual metaphor. The aim of this study was to evaluate whether PRISM measurments would be reproducible and sensitive to detect learning progress in undergraduate dental students in their clinical years.
Voluntarily participating dental students were included. To evaluate reproducibility, a mixed cohort of 10 students each in 3, 4 and 5 year (total n = 30) was recruited and received three identically structured PRISM interviews within one week without any other teaching events. To assess perceived learning progress, 29 volunteer 3 year students participated in three interviews during their clinical simulation course (beginning, middle, end). Distances between Subject and Objects was measured in millimeter; objects were classified into close or branched clusters depending on their distance from each other on the PRISM board.
Values for perceived competencies within PRISM interviews during one week were comparable between the three time points in the mixed cohort (n = 30; p > 0.05). Comparing the three subgroups (3, 4 and 5 year, each n = 10), PRISM indicated that 3 year students perceived their competencies are significantly lower than the 4 and 5 year students (p < 0.01). 3 year students had less often a branched cluster of objects than the other two groups (p < 0.05). PRISM showed that over time, 3 year students perceived a gain in their competencies in conservative dentistry and its sub-disciplines (p ≤ 0.01). The PRISM data indicated that by the end of the simulation course, the students appeared to show higher discrimination of their self-perceptions between sub-topics in conservative dentistry than at the start of the course (p = 0.01).
PRISM yields a reproducible measure of individual students' learning progress. It is a promising novel approach for appraisal in dental education. Further work is needed to confirm the generalisability of the findings.
PRISM 是一种支持牙科学生自我反思和学习评估的新方法,基于视觉隐喻。本研究的目的是评估 PRISM 测量是否具有可重复性,并能够检测临床阶段本科牙科学生的学习进展。
纳入自愿参加的牙科学生。为了评估可重复性,招募了一个由 3、4 和 5 年(共 30 名)各 10 名学生组成的混合队列,在一周内接受了三次完全相同结构的 PRISM 访谈,期间没有进行任何其他教学活动。为了评估感知到的学习进展,29 名志愿参加 3 年学生在临床模拟课程(开始、中间、结束)期间接受了三次访谈。在毫米尺度上测量主题和对象之间的距离;根据 PRISM 板上彼此之间的距离,将对象分为靠近或分支的聚类。
在混合队列(n=30)的三个时间点中,一周内 PRISM 访谈中感知到的能力值在统计学上无显著差异(p>0.05)。将三个亚组(3 年、4 年和 5 年,每组 n=10)进行比较,PRISM 表明 3 年学生感知到的能力明显低于 4 年和 5 年学生(p<0.01)。3 年学生的分支对象聚类比其他两组都少(p<0.05)。PRISM 表明,随着时间的推移,3 年学生在保守牙科及其子学科方面感知到能力的提高(p≤0.01)。PRISM 数据表明,在模拟课程结束时,与课程开始时相比,学生在保守牙科的自我认知方面表现出更高的子主题区分能力(p=0.01)。
PRISM 可重复测量个体学生的学习进展。它是一种有前途的牙科教育评估新方法。需要进一步的工作来确认研究结果的普遍性。
