To better prepare future teachers for an increasingly linguistically diverse student population, teacher education programs have integrated critical language awareness frameworks into their coursework. However, research on the influence of such coursework on teachers’ critical multilingual awareness is scarce. Given the importance of developing teachers’ critical multilingual language awareness (CMLA), this case study explores the impact of experience and course work on a novice language teacher educator and a pre-service teacher’s emerging CMLA at a large Midwestern U.S. university. It gauges teachers’ evolving awareness of the five CMLA domains (cognitive, social, affective, performance and power), with a particular focus on the power domain. Based on an iterative and recursive qualitative analysis of interview and course artifact data, this study shows that teachers are able to develop CMLA through coursework, especially if they are able to link it to personal experiences. Furthermore, a deep understanding of the power domain of language builds on (1) an awareness of the other domains of CMLA—in particular the affective and social domains—and (2) the ways these domains impact English learners’ equitable access to educational opportunities. ABSTRACT (MANDARIN) 针对语言越发多元化的中小学学生群体, 教师教育项目致力于更好地培养职前教师, 因而开始在课程中融入与批判性语言意识相关的知识框架。然而, 目前研究很少涉足这类课程如何影响教师的批判性多语语言意识(CMLA)的发展。鉴于培养老师CMLA的重要性, 本文所描述的研究探索个人经历及课程内容对一名职前语言教师教育者以及一名职前教师的已萌芽的CMLA的影响。此研究的数据搜集于一所美国中西部大学的教师教育项目。本研究衡量了教师对CMLA五个维度(认知的, 社会的, 情感的, 表现的, 及权力的)的不断发展的认识, 且集中探讨权力这一维度。通过一系列对采访与课程资料数据的迭代的和递归的质化分析, 本研究展示了通过教师教育课程发展教师CMLA的可能性, 尤其是当课程内容与教师的个人经历建立关联。此外, 教师对语言的权力维度更深层次的认识建立于(1)对CMLA其他维度的认识, 尤其是情感和社会维度;(2)对这些维度如何影响英语学习者得到的教育公平和教育机会的认识。
