Book excerpt: Spanish Heritage Learners' Emerging Literacy: Empirical Research and Classroom Practice introduces a comprehensive, multi-level empirical study on the writing abilities of Spanish Heritage Learners at the beginner level; the findings guide a broad selection of instructional activities and pedagogical resources to support writing development in the heritage language classroom. This is the first book dealing exclusively with writing competence among Spanish Heritage Language Learners through the integration of empirical evidence and instructional perspectives to address core questions on heritage language literacy. In addition to the in-depth analysis of Spanish production—spelling, verb usage, grammatical features, vocabulary, and discourse organization—the volume revises the latest perspectives within the Heritage Language Education field, and provides effective teaching approaches, innovative classroom implementations, and up-to-date resources. This versatile volume, designed for researchers and practitioners in the fields of Bilingual Education, Language Teaching Methods, and Heritage Language Pedagogy, integrates empirical evidence, global perspectives on heritage language teaching, and suggestions for further research.
