This volume focuses on the recent trend in English language pedagogy of "educational bilingualism", that is, teaching English language, contents and cultures in bilingual lessons. It draws on the critical revision of the monolingual tradition of language instruction rooted in the outdated direct method once powerful at the turn of the 20th century. The realities of education are that the English language is spreading to foreign lands, circulating alongside native tongues, functioning as a universal communication tool for multinational groups or individuals and emerging as a global language in education. This book proves the hypothesis that in the epoch of information breakthroughs and global migration, the value of English in education lies in it being the key to innovative knowledge. This leads to its integration with the learners' own language, providing alternative sources of information and marking cultural self-identity.
