This chapter discusses materials which have been developed for teaching curricular subjects in different contexts in which English is the medium of instruction (MoI) in primary and secondary schools. We outline these contexts, differing radically as they do throughout the world, and exemplify materials from three of them: Spain, the UK and Rwanda. The chapter first defines English-medium education (EME) and outlines the features of the main types of EME according to context. It describes the pedagogy which is common to good practice in EME and exemplifies this as it appears in materials in the three EME contexts. It also discusses the degree to which this pedagogy is contested, in particular with relation to translanguaging (the judicious use of two or more languages as MoI in the classroom). The chapter focuses on scarcity of materials and lack of publishing expertise as the main problems which materials development in EME faces and makes recommendations as to how these problems might be alleviated.
