The rationale behind this special issue is to underscore the importance of studying instructional materials in context—that is, how materials and textbooks are used by teachers and learners. Research on teaching materials needs to reach beyond traditional ‘armchair’ analyses and evaluations to appreciate the place of instructional materials in the wider social and educational context, and to do so in a methodologically and analytically principled manner. I begin by comparing and contrasting the concept of ‘materials use,’ which underpins the contributions to this issue, with my own concept of ‘materials consumption.’ The bulk of the coda identifies and explores various themes emerging from this special issue, including student‐generated materials, teacher and learner resistance to materials, practitioner takeaways, and the importance of content and production focused research. I compare and contrast the articles with high quality research on materials elsewhere, highlighting potentially fruitful avenues of enquiry for the next generation of studies in this rapidly growing field.

尾声：关于教学材料使用的扩展研究议程

本期特刊的基本原理是要强调在上下文中学习教学材料的重要性，也就是说，教师和学习者如何使用教材和教科书。教材的研究需要超越传统的“扶手椅”分析和评估，以了解教学材料在更广泛的社会和教育背景下的地位，并以方法和分析原则的方式进行。首先，我将“材料使用”的概念与我自己的“材料消耗”的概念进行比较和对比，后者为该问题做出了贡献。尾声的大部分内容都可以识别并探索本期特刊中出现的各种主题，包括学生编写的材料，老师和学习者对材料的抵制，从业者采取的措施，以及以内容和产品为重点的研究的重要性。我将这些文章与其他地方的高质量研究进行了比较和对比，强调了在这个快速增长的领域中进行下一代研究的潜在富有成果的研究途径。
