註釋"Violence in schools negatively affects children's future life outcomes and the culture and performance of the school. For these reasons, promoting school safety is a national priority for many federal agencies, including the National Institute of Justice. This report focuses on school safety technologies as one among many approaches to prevent and respond to school violence. In the report, the authors summarize existing research on school violence, categorize school safety technologies and describe the available research about them, present six case studies of innovative technologies as used in schools, summarize experts' views of technologies and safety problems based on interviews, and present experts' rankings of technology needs to improve school safety produced during two day-long panels. These activities revealed that some of the most pressing safety needs that technology could address relate to (1) enabling two-way communication between teachers and emergency responders; (2) "all-in-one" applications that would integrate currently fragmented and outdated school safety policies, procedures, and training for school staff and parents; (3) advances in social media monitoring; and (4) improved tip lines to make them more robust and effective. Results should be of interest to organizations and individuals involved with K-12 school technology planning, research funding, and product development"--Page 4 of cover.
