Vocabulary richness, including lexical diversity and use of rare words, has an important role in assessing proficiency, diagnosing progress and testing theory in the study of language development. This book first reviews different methods for quantifying how vocabulary is deployed in spontaneous speech and writing, and then introduces an alternative approach which can assess overall lexical diversity, measure morphology development and compare the development of different word classes. The new approach is illustrated by its application to first and second language learners.

With contributions from an international team of leading experts, this volume offers new ways to explore and measure language dominance.

This volume, dedicated to language transfer, starts out with state-of-the-art psycholinguistic approaches to language transfer involving studies on psycho-typological transfer, lexical interference and foreign accent. The next chapter on Transfer in Language Learning, Contact, and Change presents new empirical data from several languages (English, German, Russian, French, Italian) on various transfer phenomena ranging from second language acquisition and contact-induced change in word order to cross-linguistic influences in word formation and the lexicon. Transfer in Applied Linguistics scrutinizes, on the one hand, the external sources of language transfer by investigating bilingual resources and the school context, but also by pointing out the differences in academic language in multilingual adolescents. On the other hand, internal sources of language transfer in multilingual classrooms are illuminated. A final chapter directs its focus on methodological issues that arise when more than one language is studied systematically and it offers a solution on causal effects for the investigation of heritage language proficiencies. The chapter also includes studies that exploit more innovative methodologies on L1 identification and clitic acquisition.

This volume consists of a collection of papers that focus on structural/grammatical aspects of the process of first language attrition. It presents an overview of current research, methodological issues and important questions regarding first language attrition. In particular, it addresses the two most prominent issues in current L1 attrition research: Can attrition effects impact on features of core syntax, or are they limited to interface phenomena?, and; What is the role of age at onset (pre-/post-puberty) in this regard? By investigating attrition in a variety of settings, from a case study of a Spanish-speaking adoptee in the US to an empirical investigation of more than 50 long-term attriters of Turkish in the Netherlands, the investigations presented take a new perspective on these issues.

While there is much in the literature on ESL development, this book is the first of its kind to track the development of specific language abilities in an Intensive English Program (IEP) longitudinally and highlights the implications of this particular study’s findings for future IEP implementation and practice and ESL and SLA research. The volume draws on many years’ worth of data from learners at an IEP at the University of Pittsburgh to explore selected aspects of language development, including lexical, grammatical, speaking, and writing abilities, in addition to placement assessment practices and student learning outcomes. A concluding chapter points to the ways in which these findings can be applied to decision making around IEP curriculum development and the future role of IEPs in higher education more broadly. With its focus on students in IEP settings and the concentration on data from students evaluated over multiple semesters, this volume offers a unique opportunity in which to examine longitudinal developmental patterns of different L1 groups on a variety of measures from the same learners and will be key reading for students and researchers in second language acquisition, English for Academic Purposes, language education, and applied linguistics.

New quantitative methodology and the development of corpus and experimental linguistics tools have recently made researching lexical comprehension and production more accessible. While several tools and data sets are available in English (Coh-metrix, CELEX) and a few other languages, the development of resources and empirical research is still lacking in Spanish. This volume brings together original empirical research and theoretical perspectives that examine lexical development in Spanish L1, L2 and L3, with a focus on different teaching approaches and textbook coverage of Spanish lexicon in L2 curricula and the use of corpus linguistics in methodological investigations. Some questions addressed include the role of lexical development in mapping grammatical acquisition phases, the potential transfers of L1 to L2 lexical abilities, the effect of explicit vocabulary learning techniques in L2, how affective meaning modulates L2 acquisition, or how a typological understanding of lexical organization can help in teaching more effectively the lexicon of a language, among many others. The book offers an overview of what is currently being done in the field of Spanish lexical acquisition through a myriad of approaches and topics.

The Workshop on the Role of Language in School Learning: Implications for Closing the Achievement Gap was held to explore three questions: What is known about the conditions that affect language development? What are the effects of early language development on school achievement? What instructional approaches help students meet school demands for language and reading comprehension? Of particular interest was the degree to which group differences in school achievement might be attributed to language differences, and whether language-related instruction might help to close gaps in achievement by helping students cope with language-intensive subject matter especially after the 3rd grade. The workshop provided a forum for researchers and practitioners to review and discuss relevant research findings from varied perspectives. The disciplines and professions represented included: language development, child development, cognitive psychology, linguistics, reading, educationally disadvantaged student populations, literacy in content areas (math, science, social studies), and teacher education. The aim of the meeting was not to reach consensus or provide recommendations, but rather to offer expert insight into the issues that surround the study of language, academic learning, and achievement gaps, and to gather varied viewpoints on what available research findings might imply for future research and practice. This book summarizes and synthesizes two days of workshop presentations and discussion.

This unique state-of-the-art volume offers a comprehensive, systematic discussion of second language (L2) writing and L2 learning. Led by experts Rosa Manchón and Charlene Polio, top international scholars synthesize and contextualize the salient theoretical approaches, methodological issues, empirical findings, and emerging themes in the connection between L2 writing and L2 learning, and set the future research agenda to move the field forward. This will be an indispensable resource for scholars and students of second language acquisition (SLA), applied linguistics, education, and composition studies.
