Since language use is at the center of language learning, learners’ active engagement in learning activities is crucial for successful language learning. Answering the call for positive language education, the present study investigated the levels and influencing factors of engagement in English learning among 437 Chinese senior high school students. This study employed an explanatory sequential mixed-methods design, collecting data through questionnaires and semi-structured interviews. The results showed that students were generally well-engaged in English learning. Moreover, students were more inclined to engage in English learning behaviorally, emotionally, and cognitively. Students’ agentic engagement in English learning was relatively low and mainly reflected after English classes. The relatively low agentic engagement might be shaped by a series of personal and contextual factors, including the traditional Chinese concept of “honoring and respecting the teacher”, teachers’ teaching strategies, students’ learning strategies, English proficiency, learning climate, and teaching styles. Pedagogical implications for English teachers concerning enhancing students’ English learning engagement were provided.

Mindset theories have been applied to study motivation in various domains, with researchers talking about different mindsets in diverse academic domains. The domain specificity of mindsets has led second language researchers to suggest distinct mindsets concerning language ability and learning outcomes. While there is no lack of research on the application of mindset theories, a systematic synthesis of the literature on mindset theories focusing on the language education domain has remained relatively unexplored. The literature in this study was identified by conducting keyword searches in Scopus and EBSCOhost research databases using a combination of the following terms: “mindset theories”, “English as a foreign language”, “English as a second language”, and “teacher training”. The search results were limited to research articles published in English-medium refereed journals from 2013 to 2023. We scrutinized the titles and abstracts of 128 articles in the initial round of screening and did a second round of close reading for relevance to the synthesis focus. This chapter synthesizes 40 research papers on the application of mindset theories in the domain of language teaching and learning, including 1) studies on language skills such as writing, 2) studies related to language teachers’ role and teacher training, and 3) theoretical and practical applications of mindset theories. The conclusions drawn will be used to recommend future directions in research and practice. The chapter will contribute to the field of mindset theories in language education in terms of research and practice for educators and researchers.
