The COVID-19 pandemic has highlighted a continued need for innovative virtual teaching methods. Chalk talks, or brief illustrated interactive talks, are easily made virtual with an online whiteboard. We evaluated the efficacy of a live virtual chalk talk curriculum for medical students on their dermatology clerkship. A curriculum of one to three 1-h chalk talks was designed on the following topics: papulosquamous diseases, erythroderma, and immunobullous diseases. Talks were delivered monthly via Zoom to dermatology clerkship students. Pre- and post-talk surveys were administered to assess knowledge, confidence, and satisfaction. Compared with pre-talk, students ( = 18) achieved a greater percentage of possible points on knowledge assessment questions after the talks (41.0 ± 27.7% versus 90.4 ± 18.4%, < 0.001). As assessed on a Likert scale (1 = not at all confident, 5 = extremely confident), students became more confident in differentiating conditions within each disease group and working up the conditions (2.02 ± 0.53 versus 3.53 ± 0.55, < 0.001, and 2.09 ± 0.44 versus 3.76 ± 0.89, < 0.001, respectively). Qualitative responses showed that students appreciated the student-teacher interactions. In conclusion, we found that live chalk talks are an effective and engaging way to teach dermatology to medical students in the virtual setting.

新冠疫情凸显了对创新虚拟教学方法的持续需求。粉笔讲座，即简短的带插图的互动讲座，借助在线白板可轻松实现虚拟化。我们评估了针对皮肤科实习医学生的现场虚拟粉笔讲座课程的效果。设计了一门包含一至三场1小时粉笔讲座的课程，主题如下：丘疹鳞屑性疾病、红皮病和免疫性大疱性疾病。讲座每月通过Zoom平台向皮肤科实习医学生进行。在讲座前后进行问卷调查，以评估知识、信心和满意度。与讲座前相比，学生（n = 18）在讲座后知识评估问题上获得的可能分数百分比更高（41.0±27.7%对90.4±18.4%，P < 0.001）。根据李克特量表（1 = 完全不自信，5 = 极其自信）评估，学生在区分每个疾病组内的病症以及对病症进行检查方面变得更有信心（分别为2.02±0.53对3.53±0.55，P < 0.001，以及2.09±0.44对3.76±0.89，P < 0.001）。定性回答表明学生欣赏师生互动。总之，我们发现现场粉笔讲座是在虚拟环境中向医学生教授皮肤科知识的一种有效且引人入胜的方式。
