Second language teaching and learning research shows some topics of remaining interest to researchers and practitioners. Class performances have been uninterruptedly explored, although a vast amount of research on language pedagogy and applied linguistics have suggested particular implications for second language (L2) education. The concept that a pedagogical approach can fit all contexts is no longer valid. The student-centered approach has inspired investigations into learners’ needs, beliefs, and performances and provided evidence that learning outcomes sometimes do not meet teachers’ and learners’ expectations. Learner variables and contextual factors are included in research testing established hypotheses and investigating arising problems, such as technology-mediated learning and emergency teaching due to the outbreak of Covid-19.

多元语境下的第二语言教学与师范教育

第二语言教学研究显示了研究人员和从业人员仍然感兴趣的一些主题。尽管对语言教学法和应用语言学的大量研究表明对第二语言（L2）教育有特殊的意义，但人们一直在探索课堂表演。教学方法可以适应所有环境的概念不再有效。以学生为中心的方法激发了对学习者的需求，信念和表现的调查，并提供了证据表明学习成果有时不能满足老师和学习者的期望。学习者变量和上下文因素包括在研究测试中建立的假设和调查出现的问题中，例如由于Covid-19爆发而导致的技术介导的学习和紧急教学。
