In light of the UK government’s decision to make first aid education mandatory in schools, this article adds to the body of evidence to inform the implementation of this decision. Our research aimed to explore whether providing extra support to teachers increased their confidence to teach first aid, and whether this support influenced student learning outcomes. Thirty-five teachers were randomly allocated into two experimental groups and one control group. The first experimental group received support through a video medium, the second through an interactive webinar. The control group was provided with no support beyond the learning materials provided to all participants. Our analysis suggests that while providing support for teachers does not positively affect their confidence to teach first aid in the classroom, this increased support does positively affect the first aid knowledge of students.

需要何种程度的支持才能使中学教师有效地教授急救知识？一项随机试验

鉴于英国政府决定在学校强制实施急救教育，本文补充了大量证据，以告知该决定的实施情况。我们的研究旨在探讨为教师提供额外支持是否会增加他们教授急救的信心，以及这种支持是否会影响学生的学习成果。35 名教师被随机分配到两个实验组和一个控制组。第一个实验组通过视频媒体获得支持，第二个通过交互式网络研讨会获得支持。除了提供给所有参与者的学习材料之外，对照组没有得到任何支持。我们的分析表明，虽然为教师提供支持并不会对他们在课堂上教授急救的信心产生积极影响，
