BACKGROUND
An online, multiple-choice assessment was developed and validated for Youth@Work-Talking Safety, a NIOSH curriculum that equips middle and high school students with foundational workplace safety and health knowledge and skills.
METHODS
Classical Test Theory was used for the test development and validation; the Jaeger method was used for cut score determination. A total of 118 multiple-choice items were developed to measure the acquisition of knowledge and skills taught through the NIOSH curriculum. Pilot testing was conducted with 192 8-12th grade students and a cut score was determined.
RESULTS
The mean score for all test-takers on the Talking Safety assessment was 80.9%; total test reliability measured using an Alpha/KR20 statistic was 0.93. A minimum passing (cut) score of 74% was established.
CONCLUSIONS
The assessment provides an objective measure of students' acquisition of the foundational workplace safety and health competencies taught through the Talking Safety curriculum. Am. J. Ind. Med. 59:969-978, 2016. © 2016 Wiley Periodicals, Inc.
背景
针对“工作中的青少年——畅谈安全”开发并验证了一种在线多项选择题评估方法，该方法是美国国家职业安全与健康研究所（NIOSH）的一门课程，旨在为初中和高中学生提供基本的工作场所安全与健康知识和技能。
方法
采用经典测试理论进行测试开发和验证；使用耶格尔方法确定及格分数。共开发了118道多项选择题，以衡量通过NIOSH课程教授的知识和技能的掌握情况。对192名8至12年级学生进行了预测试，并确定了及格分数。
结果
在“畅谈安全”评估中，所有考生的平均分数为80.9%；使用Alpha/KR20统计量测得的总测试信度为0.93。确定的最低及格（分数线）分数为74%。
结论
该评估为学生掌握通过“畅谈安全”课程教授的基本工作场所安全与健康能力提供了客观衡量标准。《美国工业医学杂志》59:969 - 978，2016年。©2016威利期刊公司。
