Hearing a story with 31 line-by-line language switches taught new words just as effectively as hearing each language in a single block.

Read the full study notes
Researchers call this approach interleaved bilingual storytelling, and have tested it directly with bilingual children. In a randomized study, 5-year-olds heard a story with 31 line-by-line language switches and learned new words just as well as children who heard each language in a single block (Brouillard et al., 2022) . Among 2- to 5-year-olds, storybooks that mix a dominant-language narrative with second-language target words also support retention, with older preschoolers benefiting most (Read et al., 2021) . In adult learners, mixing two languages within one session likewise outperforms studying them in separate blocks (Libersky et al., 2025) .
