Uncovering the Relationship Between Buoyancy and Academic Achievement in Language Learning: The Multiple Mediating Roles of Burnout and Engagement

English learning buoyancy is a proactive and adaptable capacity that allows academic growth. However, the relationship between buoyancy, burnout, engagement, and achievement in English learning remains complex and underexplored. Grounded in the control-value theory of achievement emotions and the situated expectancy-value theory, this study investigated the impact of buoyancy and academic achievement in language learning, especially the multiple mediating roles of burnout and engagement in between. The study involved 522 senior high school students in China, who learn English as a second language. Questionnaires were employed to assess their English learning buoyancy, burnout (i.e., demotivation and exhaustion), and engagement (i.e., behavioral and agentic engagement). Academic achievement was represented by their most recent English scores. The results demonstrate that English learning buoyancy predicts academic achievement through multiple indirect paths. Specifically, exhaustion and behavioral engagement each independently mediate this relationship, and a sequential mediating pathway was identified from burnout components to behavioral engagement. The study provides pedagogical implications for English teaching.
