Spelling acquisition and development is often a challenge for Spanish Heritage Language Learners (SHLLs). Instructors, too, struggle to find the best strategies to help their students internalize orthographic rules. argues that spelling is not simply the cherry on top of good writing or a mere editing issue; rather, the skills behind the acquisition of spelling lie beneath deeper literacy development. Amàlia Llombart-Huesca discusses how to address this critical skill, including the cognitive skills underlying spelling, the role of age and bilingualism, and a thorough description of the most common types of spelling errors students make and their causes. Throughout the book, she demonstrates the importance of spelling skills by showing how they can help students improve other crucial literacy aspects, such as reading fluency, reading comprehension, and vocabulary growth. Written for instructors of SHLLs and researchers of SHL education, includes guidelines, recommendations, and ideas for creating spelling activities and meaningfully integrating them into curricula. Combining novel research and practical strategies, this is an invaluable resource for Spanish instructors and researchers.
