This study evaluated the effects of utilizing a frequency modulation (FM) system during phonological awareness intervention for students at risk for dyslexia in a classroom setting.
Four first-grade students participated in an adapted-alternating single-case design study. Participants completed intervention targeting two phonological awareness skills and were assigned to wear an FM system during lessons targeting one skill and no FM system during lessons targeting the second skill. Performance was assessed using daily assessments on the skills targeted during intervention and one additional skill.
Two participants demonstrated quicker and more pronounced improvement on the skill learned while wearing the FM system. The other two participants did not show improvement on any skill.
For children who made gains as a result of phonological awareness intervention, the FM system was associated with quicker and greater improvement. FM systems show promise as a tool to use during phonological awareness training for at least some children at risk for dyslexia.
本研究在课堂环境中，评估了在有阅读障碍风险的学生的语音意识干预中使用调频（FM）系统的效果。
四名一年级学生参与了一项适应性交替的单案例设计研究。参与者接受了针对两项语音意识技能的干预，并被分配在针对一项技能的课程中佩戴 FM 系统，而在针对第二项技能的课程中不佩戴 FM 系统。使用在干预期间针对的技能以及一项额外技能的每日评估来评估表现。
两名参与者在佩戴 FM 系统时，在所学技能上表现出更快和更显著的进步。其他两名参与者在任何技能上都没有显示出进步。
对于那些通过语音意识干预取得进步的儿童来说，FM 系统与更快和更大的进步相关。FM 系统有望成为有阅读障碍风险的儿童语音意识训练的工具。
