To describe the reach of the Heads Up "Concussion in Sports: What You Need to Know," online course and to assess knowledge change.
Online.
Individuals who have taken the free online course since its inception in May 2010 to July 2013.
Descriptive, uncontrolled, before and after study design.
Reach is measured by the number of unique participants and the number of times the course was completed by state and sport coached and the rate of participation per 100,000 population by state. Knowledge change is measured by the distribution and mean of pre- and posttest scores by sex, primary role (e.g., coach, student, and parent), and sport coached.
Between May 2010 and July 2013, the online concussion course was completed 819,223 times, reaching 666,026 unique participants, including residents from all US states and the District of Columbia. The distribution of overall scores improved from pre- to posttests, with 21% answering all questions correctly on the pretest and 60% answering all questions correctly on the posttest.
Online training can be effective in reaching large audiences and improving knowledge about emerging health and safety issues such as concussion awareness.
描述“抬头看：运动中的脑震荡：你需要知道的”在线课程的覆盖范围，并评估知识变化情况。
在线。
自2010年5月课程开办至2013年7月期间参加过该免费在线课程的个人。
描述性、非对照、前后对照研究设计。
覆盖范围通过独立参与者数量、按州和所指导运动项目划分的课程完成次数以及各州每10万人的参与率来衡量。知识变化通过按性别、主要角色（如教练、学生和家长）以及所指导运动项目划分的测试前和测试后分数的分布及平均值来衡量。
在2010年5月至2013年7月期间，在线脑震荡课程共完成819,223次，覆盖666,026名独立参与者，包括来自美国所有州和哥伦比亚特区的居民。总体分数的分布从测试前到测试后有所改善，测试前21%的人所有问题回答正确，测试后60%的人所有问题回答正确。
在线培训在覆盖大量受众以及提高对诸如脑震荡认知等新出现的健康和安全问题的认识方面可能是有效的。
