ABSTRACT
Co-teaching between native and non-native English-speaking teachers is a widespread practice in EFL contexts, where opportunities for interaction in the target language are often limited. Co-teaching exists in many forms, from the primary to tertiary levels, such as between professional non-native teachers and untrained native speakers, or between content specialists and language specialists engaging in CLIL-oriented instruction. “Quality” in co-teaching, a multifaceted concept involving a variety of stakeholders, raises several questions: What practices might foster quality co-teaching? What kind of support is necessary for ensuring quality co-teaching? This chapter will address these questions through descriptions of EFL co-teaching in Japan from the primary level through to university instruction and offer recommendations to help co-teachers develop the necessary teamwork that will lead to making a difference for their students.
