Resum:
The potential beneficial effects of oral narrative interventions have gained increasing attention in second language (L2) learning. In practice, these interventions are of different lengths (between 0.5 and 4.5-hour sessions), encompassing different formats: traditional (i.e., telling and retelling stories) and digital storytelling (i.e., using multimedia elements to create and narrate stories). The present study aims to meta-analyze the effectiveness of peer-reviewed publications on L2 oral narrative interventions, and identify potential moderators: intervention formats, proficiency and education levels. A comprehensive search in three databases yielded 35 articles meeting the inclusion criteria, with 18 providing means and standard deviations for meta-analysis.

The meta-analysis involving 22 unique groups and 574 participants found that the target intervention had an overall moderate-to-large effect on L2 learning. Notably, they had a large effect on enhancing speaking skills and a moderate effect on vocabulary. Further moderator analyses showed significant variations in the effect sizes for learners’ proficiency, with greater effectiveness observed among learners with intermediate proficiency levels. However, the effect of the intervention was not affected by format and education level.
These findings suggest that the choice between traditional and digital storytelling, as well as the implementation across various education levels may not be critical. Instead, interventions should consider learners' L2 proficiency to maximize effectiveness. Importantly, due to limited samples and a large variation in effect sizes, further research is needed to assess the effects of narrative interventions with larger sample sizes and diverse populations. Furthermore, a more systematic exploration of the effectiveness of the specific techniques and design features used within those narrative programs is needed.
