This study investigates the theoretical dimensions of how machine translation (MT) plays a role in relation to L1 reading competence in L2 reading comprehension. Leveraging Kintsch’s Construction-Integration (CI) model for L2 reading proposed by Oh (2014), our research posits that MT mediation enhances the textbase by alleviating constraints related to L2 proficiency. This, in turn, facilitates a more effective utilization of L1 reading resources, contributing to an enriched situation model. To explore this hypothesis, we conducted an empirical study with 89 college students enrolled in a general English course at a South Korean university. Participants engaged in reading activities under two conditions: a pre-MT (reading without MT) and a post-MT (reading with MT). The comprehensive model, incorporating a textbase indicated by L2 vocabulary, grammar, and sentence parsing, and a situation model represented by L1 reading competence, was examined through structural equation modelling across these conditions. Additionally, we analyzed learning potential scores (LPS)—reflecting the difference between the two conditions—using hierarchical multiple regression to identify significant predictors of enhanced comprehension with MT use. Our findings confirm the validity of the models, demonstrating the textbase as a key mechanism through which MT influences reading comprehension. The results also underscore the significance of L1 reading competence and L2 parsing ability as key predictors for LPS. These findings are discussed within the context of the changing multiliteracies landscape, contributing to the broader discourse on language education and technology integration. KCI Citation Count: 0
