The book addresses challenges others are likely to experience while improving teacher preparation, including preservice teacher resistance, the challenge of adding to already-packed courses, the difficulty of recruiting and retaining busy faculty members, and the question of how to best frame the larger issues. The authors also address options for integrating the work of improving teacher preparation for linguistic diversity into a variety of different teacher education program designs. Finally, the book demonstrates a data-driven approach that makes this work consistent with many institutions' mandate to produce research and to collect evidence supporting accreditation.
