Principles of Language Learning and Teaching: A Course in Second Language Acquisition

Citation

Brown, H. D., & Lee, H. (2025). Principles of Language Learning and Teaching: A Course in Second Language Acquisition (7th ed.). Routledge.

Chapter Summary

The seventh edition is a compact book: ten chapters fill about 220 pages, followed by a bibliography, a glossary and author and subject indexes (Routledge gives 282 pages in all). Chapters are fairly even in length, from about 13 pages (Chapter 1) to about 30 (Chapter 5). The publisher's description names the recurring features: "Points to Ponder" questions for personal reflection, classroom connections, "Tips for Teaching", suggested readings and the glossary. It also lists what the edition redefines or adds: language learning in an era of globalization and multilingualism; transnationalism, identity, investment, agency and ideology; learning as situated, usage-based and socioculturally contextualized; emotional engagement, intercultural sensitivity and self-efficacy; and transdisciplinary and ecological approaches. The book moves from foundations (Chapters 1–2), through factors in the learner (Chapters 3–6) and the learner's developing language (Chapter 7), to three families of theory (Chapters 8–10).

Chapter 1: Language, Learning, and Teaching

The shortest chapter sets out the three terms of the title and the questions the rest of the book takes up. It is the place to establish the book's vocabulary before the research survey begins.

Chapter 2: Overview of SLA Research

A survey of second language acquisition research as a field, giving the map against which the later chapters on particular factors and theories can be placed. The publisher states that the edition keeps the historical information and foundational ideas of SLA that teachers have found useful, alongside current research.

Chapter 3: Age and Language Development

The chapter on age, one of the classic questions in SLA. Among the frequent terms Google Books lists for the book are the critical period hypothesis and bilingualism, which belong to this debate.

Chapter 4: Neurobiology of Language Learning

A chapter on the brain and language learning. Terms such as neuroplasticity and declarative and procedural memory appear among the book's frequent terms, which indicates the kind of material treated here.

Chapter 5: Motivation, Identity, and Agency

The longest chapter, about 30 pages, brings together motivation with identity and agency. It is the chapter that most directly carries the edition's new emphases on identity, investment, agency and ideology, and on emotional engagement and self-efficacy.

Chapter 6: Aptitude and Cognitive Differences

Individual differences of a cognitive kind: language aptitude and other differences in how learners process and approach learning. Language learning strategies and self-regulated learning are among the book's frequent terms and fit here.

Chapter 7: Learner Language and Crosslinguistic Influences

The learner's developing language system and the influence of other languages the learner knows. Interlanguage, code-switching, multicompetence and translanguaging are among the book's frequent terms, consistent with the edition's framing of learning in a multilingual world.

Chapter 8: Cognitive and Processing Approaches

The first of three theory chapters: accounts of acquisition in terms of cognition and the processing of input and output. Input, the output hypothesis and the work of VanPatten appear among the frequent terms.

Chapter 9: Sociocultural Theory and Additional Language Learning

Learning as a socially mediated process. Scaffolding and the work of Lantolf are among the frequent terms. The chapter title's "additional language" reflects the edition's attention to multilingual learners rather than to a single "second" language.

Chapter 10: Ecological and Transdisciplinary Approaches to Language Learning and Teaching

The closing chapter presents ecological and transdisciplinary approaches, which the publisher describes as keys to language teaching in the twenty-first century. It is the book's most current material and connects the theories back to teaching.

Key Concepts

Chapters 1–4: Foundations, Age and the Brain

• Second language acquisition (SLA): the research field the book surveys for teachers.
• Age and language development: how the age at which learning begins relates to the course and outcome of learning.
• Neurobiology of language learning: what is known about the brain's role in learning a language.

Chapters 5–6: Learner Differences

• Motivation: the reasons for, and intensity of, a learner's effort.
• Identity, investment and agency: how learners' sense of self, their stake in the language and their capacity to act shape learning.
• Emotional engagement and self-efficacy: the affective side of learning and a learner's belief in their ability to succeed.
• Aptitude: individual differences in the cognitive capacity for language learning.

Chapter 7: Learner Language

• Learner language: the learner's developing system, studied in its own right.
• Crosslinguistic influence: the effect of previously known languages on a new one.

Chapters 8–10: Theories

• Cognitive and processing approaches: acquisition explained through attention, memory and the processing of language.
• Sociocultural theory: learning as mediated by social interaction and cultural tools.
• Usage-based and situated learning: language learned through use in particular contexts.
• Ecological and transdisciplinary approaches: views that treat learning as part of a wider web of social, cognitive and environmental relations.

Critical Analysis

Strengths

• Built for teacher education. The publisher presents the book as a resource for language teacher education programs and for both novice and experienced teachers, and the features named on the product page (reflection questions, classroom connections, teaching tips) keep each chapter tied to practice.
• Updated theoretical frame. The concepts the publisher lists as redefined or new (multilingualism, transnationalism, identity and agency, usage-based and ecological views, intercultural sensitivity) are reflected in the chapter titles themselves, notably Chapters 5, 7, 9 and 10.
• Manageable length. Ten chapters of roughly 13–30 pages make the book easy to divide across a semester, and the glossary supports readers new to the terminology.
• Continuity with a familiar text. The previous, sixth edition (2014) was Brown's alone; the seventh adds Heekyeong Lee as co-author, and the publisher notes that it keeps the foundational material teachers found useful.

Limitations

• Less room for depth. At about 220 pages of text for the whole of SLA, each topic gets a single chapter of around 20 pages. Readers who need the research evidence in detail will need a fuller survey alongside it.
• Theory chapters are selective. Only three groups of approaches receive their own chapters (cognitive and processing, sociocultural, ecological and transdisciplinary). The contents do not show how fully other theoretical positions are covered within the research overview in Chapter 2, so a course that needs a balanced survey of theories should add a theory-focused text.
• Earlier editions differ. Course materials and secondary citations based on the sixth edition will not match this edition's chapters, so students should check which edition a syllabus refers to.

Where It Fits in the Course

Within this course, Brown and Lee sits between short introductions and research-level surveys. Lightbown and Spada's How Languages Are Learned is a shorter, more accessible introduction to the same territory, also aimed at teachers, and makes a good first reading. Hunston and Oakey's Introducing Applied Linguistics and Schmitt and Rodgers's An Introduction to Applied Linguistics cover the wider field of applied linguistics, in which SLA is one area among several; they are the books to use if the course is a general introduction rather than an SLA course.

After Brown and Lee, two books go further into the research. VanPatten, Keating and Wulff's Theories in Second Language Acquisition gives each major theory its own chapter written by a specialist in a common format, which extends Brown and Lee's Chapters 8–10. Ellis's The Study of Second Language Acquisition is a large reference survey of the whole field, useful for following up any chapter in detail.

How to Use This Book

The book suits students in MA TESOL or language-teacher education programs, practising teachers, and undergraduates in applied linguistics. No background in linguistics is needed, though some experience of learning or teaching a language makes the reflection questions more productive.

A practical plan for a one-semester course:

• Weeks 1–2: Chapters 1–2 for the vocabulary and the map of the field.
• Weeks 3–8: Chapters 3–7, one chapter a week, with an extra week for Chapter 5, the longest and the one most tied to the edition's new emphases.
• Weeks 9–12: Chapters 8–10 as a unit on theory. Read them in order, since the book moves from individual cognition to social and ecological perspectives.

Work through the "Points to Ponder" questions while reading rather than afterwards; they are designed for personal reflection and work well as discussion prompts. Use the "Tips for Teaching" and classroom connections to plan a short teaching activity or reflective journal entry for each chapter. Keep the glossary at hand. For any topic that becomes the subject of an essay, move from the suggested readings to the more detailed surveys listed above.
