The roles of task-specific self-efficacy and enjoyment in EFL learners’ development of speaking CALF: A longitudinal study

Abstract

This longitudinal study adopts a person-centred approach to examine EFL learners' development of speaking CALF; the fluctuating correlations of affective ID variables (self-efficacy and enjoyment), as well as their impacts on oral task performance over time. Thirty-one Chinese EFL learners completed eight oral tasks bi-weekly over six months, followed by post-task scales to measure task-specific self-efficacy and enjoyment. Data were subjected to group-based multi-trajectory modelling (GBMM) to discern the development of speaking CALF, moving correlation analysis to explore the interactions between task-specific self-efficacy and enjoyment, and panel data regression to examine the longitudinal impact of task-specific self-efficacy and enjoyment on oral task performance. GBMM results revealed variability at both the group and individual levels, despite similar educational backgrounds and learning contexts, as evidenced by differing speaking CALF patterns. Moving correlation analyses revealed dynamic, non-linear trends between self-efficacy and enjoyment. Panel data regression analyses suggested that higher levels of affective ID variables would generate better oral performance, as evidenced by speaking CALF patterns. This study successfully integrated ID variables into TBLT research within a CDST framework for enhancing our understanding of the complex nature of EFL learners’ speaking competence and underscoring the interconnectivity between task-specific self-efficacy and enjoyment.
