Exploring the interplay of language mindsets, self-efficacy, engagement, and perceived proficiency in L2 learning

Language mindsets, which are beliefs about personal qualities relevant to language learning and perceived as either fixed or malleable, have become a focus in understanding their roles in shaping language learning processes. Several studies show how they are related to language learning, along with important variables such as self-efficacy. Although research on language mindsets is growing, most studies have focused on their isolated effects, leaving a critical gap in understanding how these mindsets interact with other significant factors to influence language learning in a motivational aspect. This study aimed to address this gap by exploring the interplay between language mindsets, self-efficacy, engagement, and perceived proficiency (PP)-a construct that reflects an individual's subjective perception of their language skills and is linked to their motivation to learn. A total of 257 students enrolled in English language courses from three universities in Korea joined the study by responding to questionnaires. The results of the path analysis show that a growth mindset did not predict self-PP; notably, however, it predicted PP with the full mediation of self-efficacy. In addition, the indirect effect of the relationship between self-efficacy, engagement, and proficiency was significant but weak. However, the inclusion of a growth mindset strengthened the indirect effect. Conversely, the link between a fixed mindset and PP showed no significant indirect effect through self-efficacy and engagement. The findings highlight the importance of a growth mindset in initiating the process of language learning and underscore the mediating role of self-efficacy in this context, contributing to the development of more effective and pedagogically informed guidance in L2 classrooms.
