The present study aimed to explore how pre-service teacher’s individual regulatory focus orientation, currently emerging as an interesting learner variable for language learning, could influence their Englishspeaking abilities. English teaching demonstration videos of 67 pre-service teachers were analyzed in terms of pronunciation, accuracy, and fluency. The regulatory focus orientations of participants were evaluated using a questionnaire. The results of data analysis, using multiple regression analysis, indicated that promotion-focus orientation was a significant positive predictor for pronunciation, fluency (words per minute, ratio of dysfluency), and accuracy (lexical errors, ratio of error-free AS-units). On the other hand, prevention-focus orientation did not emerge as a statistically significant factor affecting accuracy. However, it was observed to have a negative influence on both pronunciation and fluency. In light of the research findings that highlight the favorable impact of a promotion-focus orientation, suggestions were made for future teacher training programs aimed at enhancing the English proficiency of pre-service teachers.

Many empirical findings of previous studies have suggested a connection between motivational factors and L2 writing. Nonetheless, the impact of motivational factors on the genre-based L2 writing has not gained much attention. The present study explored the extent to which the characteristics of two writing tasks involving different genres interact with a learner’s motivational disposition (regulatory focus) and, further, affect language production of writing. 106 essays collected from 53 university EFL learners were assessed in terms of linguistic complexity and accuracy. 2X2 ANOVA results revealed significant main effects of genre on lexical complexity (lexical variation and MSTTR). More importantly, there were significant interaction effects between genre and regulatory focus on both measures of the syntactic complexity (mean length of T-unit and clause per T-unit) and lexical complexity (lexical density). The findings highlighted the significance of learners’ motivational dispositions in genre writing. Drawing on the findings, some pedagogical suggestions to ensure the effectiveness of writing tasks on L2 development were proposed.
