Despite the importance that goals have for language learning (Lee & Bong, 2019), little is known about the effects on learner behaviours. Combining individualized (idiographic) and standardized (nomothetic) methodologies, this study investigated whether the self-concordance of learning goals formulated at the beginning of a program of language education affected engagement and resilience at the end of the first year. Following research demonstrating the mediating roles of goal effort and goal progress (Vasalampi et al., 2009), these variables were included in the study design. Participants were 41 teacher education students on a university program in Turkey. Data was collected on four occasions over two semesters. Analyses were carried out using path modelling. Results showed that starting the program with self-concordant goals had positive effects on engagement and resilience later in the year. Effects of self-concordance were mediated by goal effort and goal progress. For engagement, a direct effect of self-concordance was also found. Findings point to an important relationship between the quality of language learners’ goals and L2 learning behaviours. Further, the study highlights the value of idiographic methods in goal-focused research.
