1 Introduction

The importance of listening in second language teaching and research is increasing, but research on listening acquisition and understanding mechanisms is still insufficient. There are deficiencies in both theoretical and practical aspects of second language listening research in China, and the research results are disconnected from teaching practice. Although there have been discussions in recent years, the quantity and depth of research still need to be improved. The "Routledge Handbook on Second Language Acquisition and Listening" systematically reviews the current development status and future trends of second language listening research, covering multiple aspects such as theoretical foundations, core issues, teaching and assessment practices, and emerging topics. It provides a theoretical foundation and practical methods for listening teaching and research, which is of great significance.

2 Content Introduction

The book consists of 29 chapters, divided into four parts. The first part explores the cognitive process of second language listening comprehension, phonetic acquisition, theoretical perspectives on listening development, and the influence of cognition, emotion, and age on listening proficiency. The second part discusses core topics such as vocabulary knowledge, multimodal teaching, listening input, vocabulary and grammar knowledge, pragmatics perspective, listening as an interactive ability, and speech comprehensibility. The third part involves second language listening teaching methods, machine assisted testing, language flow segmentation skills, cognitive diagnosis pathways, learning challenges for hearing-impaired groups, academic English listening teaching, and children's second language listening teaching and assessment. The fourth part focuses on visual cues, second language interactive listening, multimodal teaching perspectives, listening teaching in the context of English as a lingua franca, emerging technology assisted teaching and research, as well as cutting-edge issues in second language listening teaching and research.

3 Brief Review

Discussed the importance and characteristics of the Routledge Handbook of Second Language Acquisition and Listening. In the past two decades, there have been relatively few research works in the field of second language listening acquisition. However, this handbook comprehensively summarizes research topics and achievements, providing a systematic theoretical framework and practical guidance. The manual has four major characteristics: coherent and rigorous chapter structure, taking into account diverse needs; Theoretical exploration is comprehensive and instructive; Teaching practice is based on second language acquisition theory and listening research results; The content system is complete and forward-looking. The manual covers all the topics and key results of second language listening acquisition research, demonstrating the development trajectory and research gaps in this field, outlining the development trends and cutting-edge dynamics. Theoretical perspectives continue to deepen, interdisciplinary methods are introduced, and cutting-edge technology applications are expanded. The manual provides a highly valuable reference for domestic researchers, second language teachers, and learners.
