Both in the research literature on tasks and second language learning and in the pedagogical literature on task-based language teaching (TBLT), the role of the teacher has received scant attention. In this article, the role of the teacher in TBLT is approached from three perspectives: (a) the teacher as mediator of the students’ language development, contributing to the effectiveness of TBLT as a pedagogical approach to second language education; (b) the teacher as a key figure in the implementation of TBLT, and thus as a change agent in the innovation of second language education; and (c) the teacher as researcher, and thus as an active contributor to the development and further refinement of TBLT as a researched pedagogy.

教师在任务型语言教育中的作用

在关于任务和第二语言学习的研究文献和关于任务型语言教学（TBLT）的教学文献中，教师的作用都很少受到关注。本文从三个角度探讨教师在 TBLT 中的作用： (a) 教师作为学生语言发展的中介，有助于 TBLT 作为第二语言教育教学方法的有效性；(b) 教师是实施 TBLT 的关键人物，因此是第二语言教育创新的变革推动者；(c) 教师作为研究人员，因此作为研究型教学法的 TBLT 发展和进一步完善的积极贡献者。
