Tania Ionin is Professor of Linguistics and Director of Graduate Studies in Linguistics at the University of Illinois at Urbana-Champaign. Her research expertise is in second language acquisition of semantics, and in experimental semantics more generally. She has taught courses in second language acquisition, psycholinguistics, research design and methodology for linguists, and pedagogical English grammar, among other subjects. Silvina Montrul is Professor of Spanish and Linguistics at the University of Illinois at Urbana-Champaign, and directs the Second Language Acquisition and Bilingualism Lab. Her research focuses on linguistic and psycholinguistic approaches to second language acquisition and bilingualism – in particular, syntax, semantics, and morphology – and on language acquisition in heritage speakers. She regularly teaches courses in second language acquisition, bilingualism, and the structure of Spanish.

• List of figures; List of tables; List of boxes; Preface; Acknowledgements, Abbreviations used in glosses for non-English examples; 1. Theoretical foundations; 2. Intervention research and grammar teaching; 3. Articles; 4. Verb placement and question formation; 5. Inflectional morphology; 6. Subjunctive mood; 7. Argument structure; 8. Direct and indirect objects; 9. Word order and related syntactic phenomena; 10. Where to go next; Glossary; References; Index.

'This textbook will equip the next generation of researchers and practitioners for optimized intervention studies. Informed by the state of the art, it discusses which types of information can be useful to the language learner, identifies remaining gaps in evidence, and suggests promising techniques to investigate them. The extensive and clearly illustrated glossary of linguistic terms is a great pedagogical resource in itself.' Cecile De Cat, University of Leeds
