This edited volume extends our field of studies by highlighting novel 21st century curricular designs and pedagogical practices in the preparation of future bilingual teachers and their relevance for advancing curriculum, instruction, and educational achievement across bilingual school contexts. In particular, the volume provides a much-needed overview of innovative bilingual teacher preparation practices designed and implemented to develop bilingual teacher professionals equipped to effect curricular and pedagogical changes in bilingual settings. As such, two main questions guiding the orchestration of the volume are: (a) What innovative curricular and pedagogical designs characterize the field of bilingual teacher education in 21st century? and (b) How do or could these innovative curricular and pedagogical approaches for educating future bilingual teachers influence teacher practices in bilingual contexts for advancing curriculum, pedagogy and the achievement of bilingual learners?
