This webinar presents a study examining the mechanisms through which multilingual students’ information literacy (IL) experiences in their first language contribute to their perceived ability to engage in IL practices in a second language. Drawing on translanguaging theory, social cognitive theory, and research on cross-linguistic literacy transfer, the study investigates the interplay among first-language IL experiences, translanguaging self-efficacy, transpositioning self-efficacy, and second-language IL self-efficacy. In addition to variable-centered analyses, a person-centered approach is employed to identify distinct learner profiles based on students’ first-language IL experiences, translanguaging self-efficacy, transpositioning self-efficacy and examine the differences regarding their second-language IL self-efficacy. Findings highlight the critical role of multilingual resources in shaping IL development, offering implications for more inclusive, asset-based pedagogies in multilingual and higher education contexts.
