Based on the motivation theories, we postulated that interest in learning languages influences the self-efficacy beliefs of students about their capabilities as second/foreign language (L2) English learners. This study examined the longitudinal causal relation between affective interest and cognitive self-efficacy in the L2 motivational context using the Gyeonggi Education Panel Study (GEPS) data from South Korea. A secondary school student sample from 2015–2020 GEPS over six years comprised 6,314 students (3,189 males and 3,125 females). Using a parallel growth model (PPM) with Mplus 8.4, the results indicated that the initial level and growth rate of L2 English interest positively predicted L2 English self-efficacy. Subsequently, the initial level of L2 English interest exhibited a negative cross-effect on the growth rate of L2 English self-efficacy. Finally, the sequential causal effect of L2 English interest on self-efficacy was found across the six-year period. The findings are discussed in terms of the pedagogical implications in English learning and teaching practices and further research.

본 연구는 수학 수업에서 배움의 즐거움을 찾지 못하고, 수학 자신감이 부족하여 수학 교과에 대한 두려움을 갖고 있는 학생들이 쉽고 재미있게 수학을 공부하는 경험을 통하여 학습자의 수학 흥미도와 자신감을 키울 수 있도록 수학 수업 방법을 변화시키기 위하여 이루어졌다. 연구의 목적을 효율적으로 달성하기 위하여 수학에 대한 흥미와 자신감을 키울 수 있는 학생 중심의 참여형 수업 구현을 위해 거꾸로 수학교실 적용을 위한 환경을 구축하였고, 학생 중심의 참여형 수업 방법과 융합적·창의적 사고력을 향상시킬 수 있는 평가 방안을 구안하였으며, 학생 중심의 참여형 수업을 함께 연구하는 수업 교사 동아리를 구성·운영하여 수업 방법 개선의 성공 경험을 공유하였다.

The current study aimed to explore how students’ L2 writing self-efficacy and interest contribute to strategy use and writing performance. An exploratory factor analysis with 212 Korean college students’ self-reported motivation scores revealed three underlying constructs of self-efficacy, communicative interest, and instrumental interest. Subsequent multiple regression analyses indicated significant positive relations between self-efficacy and the five types of strategy use. Communicative interest appeared to positively contribute to use of planning,monitoring, and compensatory strategies. Instrumental interest was a predictor of retrieval and compensatory strategies. L2 writing strategy use was a statistically significant but minor contributor to L2 writing performance. The current study also suggests that students’ instrumental interest and communicative interest should be balanced. Further research is needed to identify mitigating effects of L2writing strategy use for motivation and performance development.
