Book excerpt: The Second Handbook of English Language Teaching provides a comprehensive examination of policy, practice, research and theory related to English language teaching in international contexts. Over 70 chapters focus on the research foundation for best practices, frameworks for policy decisions, and areas of consensus and controversy in second-language acquisition and pedagogy. In countries around the globe, English has become the second language taught most frequently and intensively. In many countries, particularly in Asia, government policies have made English a part of the curriculum from primary school on. Demand for English teaching by parents and adult learners is fueled by the desire to increase economic competitiveness, globalization of the workforce, immigration, and a move toward lifelong learning. Immigration has led to an increased demand for English-language teaching even in countries where English is the dominant language.
