How language learners and teachers actually use pedagogical materials in classrooms is a ‘groundbreaking’ subject of applied linguistics inquiry (Tarone, 2014, p. 653), referred to in this research agenda article as materials use. We begin with a theoretically-oriented overview of language education scholarship on pedagogical materials (henceforth materials). Then, we focus on seven qualitative research tasks across three thematic areas, namely materials use and: (A) language pedagogy, (B) classroom interaction, and (C) language diversity, culture, and power. The first section on pedagogy outlines research tasks on: (1) the roles of materials in classrooms, (2) the influences of materials on practicing educators’ expertise, and (3) how language teacher education programmes address materials use. The second section on classroom interaction proposes inquiry into: (4) polysemiotic patterns of materials-in-interaction, and (5) the expected and unexpected outcomes of materials regarding students’ target language use. The third section focuses on: (6) teachers’ and learners’ responses to diverse linguistic varieties and cultures represented in materials, and (7) instructional materials used in language policy and planning endeavours. Throughout this article we reference interdisciplinary connections to curriculum studies, cultural studies, sociology, and materials scholarship in general education. The seven research tasks are critical next steps for understanding materials use – a vast new field that promises to advance language education practice and theory.

语言学习者和教师如何在课堂上实际使用教学材料是应用语言学探究的一个“开创性”主题（Tarone，2014 年，第 653 页），在本研究议程文章中称为材料使用。我们首先对教学材料（以下简称材料）的语言教育奖学金进行理论导向的概述。然后，我们专注于三个主题领域的七项定性研究任务，即材料使用和：(A) 语言教学法，(B) 课堂互动，以及 (C) 语言多样性、文化和权力。关于教学法的第一部分概述了以下方面的研究任务：（1）材料在课堂中的作用，（2）材料对实践教育者专业知识的影响，以及（3）语言教师教育计划如何解决材料的使用问题。关于课堂互动的第二部分建议探究：（4）互动中材料的多符号模式，以及（5）关于学生目标语言使用的材料的预期和意外结果。第三部分侧重于：（6）教师和学习者对材料中代表的不同语言种类和文化的反应，以及（7）语言政策和规划工作中使用的教学材料。在整篇文章中，我们提到了通识教育中与课程研究、文化研究、社会学和材料研究的跨学科联系。这七项研究任务是理解的关键下一步材料使用——一个广阔的新领域，有望推动语言教育实践和理论。
