Video-based worked examples enable medical students to successfully prepare for breaking-bad-news (BBN) encounters with simulated patients (SPs). This is especially true when examples include hints that signal important content. This paper investigates whether the beneficial effect of hints only applies to video-based worked examples or also text-based examples.
One-hundred-and-forty-seven fourth-year medical students attending a BBN training participated in either of two equally scaffolded, randomised field trials. Prior to encountering SPs, the students worked through an e-learning module introducing the SPIKES protocol for delivering bad news; it contained the same worked example presented to either of four groups as text or video, with or without additional hints denoting the SPIKES steps being implemented.
Only a main effect of 'hints' was revealed, implying that students in the hints groups delivered the news to an SP significantly more appropriately than those in the without-hints groups.
Independent of their presentation format, worked examples with hints best foster students' BBN skills learning.
In addition to video, text-based worked examples can effectively prepare students for BBN simulations if hints are included. This offers an affordable alternative to video examples, as text examples can be generated with less effort.
基于视频的实例可以帮助医学生成功为与模拟患者(SP)的不良消息传递(BBN)做好准备。当实例包括提示信号重要内容的提示时,这一点尤其正确。本文探讨了提示的有益效果是否仅适用于基于视频的实例,或者也适用于基于文本的实例。
147 名参加 BBN 培训的四年级医学生参加了两个同等的随机现场试验之一。在与 SP 接触之前,学生们通过一个电子学习模块学习了 SPIKES 协议,用于传递不良消息;它包含以文本或视频形式呈现给四个组中的任何一个的相同工作实例,带有或不带有表示正在实施 SPIKES 步骤的附加提示。
仅揭示了“提示”的主要效果,这意味着提示组的学生向 SP 传递消息的方式明显比没有提示组的学生更合适。
无论呈现格式如何,带有提示的工作实例都可以最好地促进学生的 BBN 技能学习。
除了视频外,如果包含提示,基于文本的工作实例也可以有效地为 BBN 模拟做好学生的准备。这为视频实例提供了一种经济实惠的替代方案,因为文本实例可以更轻松地生成。
