Our purpose is to present findings regarding student attitudes towards a virtual PBL program used to standardize their pediatric clinical experience.
With funding provided by the Fund for the Improvement of Post-Secondary Education, we developed Project LIVE (Learning through Interactive Video Education), a CD-ROM/Web hybrid program that uses digital video cases to conduct "virtual" problem-based learning groups with students doing a clinical rotation in a remote setting. Cases were progressively disclosed by videos of patient/physician encounters on a CD-ROM. Groups of five students and a faculty facilitator collaborated, teaching each other within the discussion section of the program. We conducted a multifaceted evaluation of Project LIVE to study the impact of case modality or distance on student learning and attitudes. We placed students in one of three groups (1) a face-to-face group with a paper case (FFT), (2) a face-to-face group with a video case (FFV), and (3) a virtual group (VG) with the digital video case. We then studied student attitudes about the three teaching formats. Over a six-month period three education specialists, who were not a part of the development team, conducted eight focus groups lasting one hour to assess student attitudes about Project LIVE. No one from the project team was present during these groups, and an independent evaluator analyzed the notes taken by each focus group leader.
Trends across the groups included the following: (1) Authenticity (video)-Students reported that the authenticity of the case was a critical feature and that, "seeing (videos) made learning more memorable." Virtual and FFV groups reported more confidence in their ability to recognize abnormal findings in their patients. "You can't expect to teach clinical exam skills with a piece of paper." (2) Use of time-Students from all groups believed the cases were a good use of their time and improved their ability to solve clinical problems. They said it gave them an opportunity to "get away from just doing and focus on learning." However, the virtual groups complained of the lack of "a barometer for how much is too much" time. Some students reported spending an average of eight to ten hours per case over the period of a week. (In contrast, face-to-face groups met for three hours.) (3) Modeling clinical reasoning-Students believed the cases were valuable in structuring their knowledge, conceptualizing how to handle difficult situations, distinguishing abnormal from normal physical examination findings, and collaborating with their peers and their mentor to develop critical thinking. "It forced us to be logical" and ". how to think through the process-it mimics the real setting." (4) Technical support-The responsiveness of the Project LIVE staff was essential in assisting students in troubleshooting problems. (5) Distance component-Students preferred to work through the cases in face-to-face groups but agreed that the virtual experience is "good if you are in the middle of nowhere." This program was enjoyed by students and gave us an approach to standardizing experiences across multiple clinical sites.
我们的目的是展示有关学生对用于规范其儿科临床经验的虚拟问题式学习项目的态度的研究结果。
在高等教育改进基金的资助下,我们开发了“通过交互式视频教育学习”(LIVE)项目,这是一个光盘/网络混合项目,它使用数字视频病例来开展“虚拟”问题式学习小组,让学生在远程环境中进行临床轮转。病例通过光盘上患者/医生会诊的视频逐步呈现。每组五名学生和一名教师辅导员合作,在项目的讨论部分相互教学。我们对LIVE项目进行了多方面评估,以研究病例形式或距离对学生学习和态度的影响。我们将学生分为三组之一:(1)使用纸质病例的面对面小组(FFT),(2)使用视频病例的面对面小组(FFV),以及(3)使用数字视频病例的虚拟小组(VG)。然后我们研究了学生对这三种教学形式的态度。在六个月的时间里,三名并非开发团队成员的教育专家进行了八个时长一小时的焦点小组讨论,以评估学生对LIVE项目的态度。在这些小组讨论期间,项目团队中没有人在场,一名独立评估人员分析了每个焦点小组组长所做的笔记。
各小组的趋势如下:(1)真实性(视频)——学生报告称病例的真实性是一个关键特征,并且“观看(视频)使学习更令人难忘”。虚拟小组和FFV小组表示对识别患者异常发现的能力更有信心。“你不能指望用一张纸来教授临床检查技能。”(2)时间利用——所有小组的学生都认为病例很好地利用了他们的时间,并提高了他们解决临床问题的能力。他们说这给了他们一个“摆脱单纯的操作,专注于学习”的机会。然而,虚拟小组抱怨缺乏“一个时间上限的衡量标准”。一些学生报告称在一周的时间里每个病例平均花费八到十个小时。(相比之下,面对面小组会面三个小时。)(3)构建临床推理——学生认为病例在构建他们的知识、构思如何处理困难情况、区分体格检查的异常与正常发现以及与同伴和导师合作以培养批判性思维方面很有价值。“它迫使我们变得有逻辑”以及“如何思考整个过程——它模仿了真实场景”。(4)技术支持——LIVE项目工作人员的响应能力对于帮助学生解决问题至关重要。(5)远程部分——学生更喜欢在面对面小组中完成病例,但也认同虚拟体验“如果你身处偏远地区就很好”。这个项目受到了学生的喜爱,并为我们提供了一种在多个临床地点规范临床经验的方法。
