This study examined 2nd-grade teachers' perceptions of the academic, social, and behavioral competence of students with speech sound disorders (SSDs).
Forty-eight 2nd-grade teachers listened to 2 groups of sentences differing by intelligibility and pitch but spoken by a single 2nd grader. For each sentence group, teachers rated the speaker's academic, social, and behavioral competence using an adapted version of the Teacher Rating Scale of the Self-Perception Profile for Children (S. Harter, 1985) and completed 3 open-ended questions. The matched-guise design controlled for confounding speaker and stimuli variables that were inherent in prior studies.
Statistically significant differences in teachers' expectations of children's academic, social, and behavioral performances were found between moderately intelligible and normal intelligibility speech. Teachers associated moderately intelligible low-pitched speech with more behavior problems than moderately intelligible high-pitched speech or either pitch with normal intelligibility. One third of the teachers reported that they could not accurately predict a child's school performance based on the child's speech skills, one third of the teachers causally related school difficulty to SSD, and one third of the teachers made no comment.
Intelligibility and speaker pitch appear to be speech variables that influence teachers' perceptions of children's school performance.
本研究考察了二年级教师对语音障碍(SSD)学生的学业、社交和行为能力的看法。
48名二年级教师听取了由一名二年级学生说出的两组句子,这两组句子在可懂度和音高上有所不同。对于每组句子,教师使用儿童自我认知量表教师评定量表(S. 哈特,1985年)的改编版本对说话者的学业、社交和行为能力进行评分,并回答3个开放式问题。匹配伪装设计控制了先前研究中固有的混淆说话者和刺激变量。
在中等可懂度语音和正常可懂度语音之间,教师对儿童学业、社交和行为表现的期望存在统计学上的显著差异。与中等可懂度的高音调语音或任何一种具有正常可懂度的音高相比,教师将中等可懂度的低音调语音与更多的行为问题联系在一起。三分之一的教师报告说,他们无法根据孩子的语言技能准确预测孩子的学业表现,三分之一的教师将学业困难与语音障碍因果关联,三分之一的教师未作评论。
可懂度和说话者音高似乎是影响教师对儿童学业表现看法的语音变量。
