This study examined whether approaches to learning moderate the association between home literacy environment and English receptive vocabulary development. The Head Start Family and Child Experiences Survey (2003 cohort) was used for analysis. Latent growth curve modeling was utilized to test a quadratic model of English receptive vocabulary development. Results showed that children's approaches to learning significantly moderated the influence of home literacy environment on English receptive vocabulary development. Post hoc probing of the simple slopes demonstrated that children with more positive approaches to learning and lower levels of home literacy environment had a higher English receptive vocabulary trajectory. The implications of the study results for early literacy interventions are discussed. Practice or Policy: Findings from this study may have implications for early educators who aim to improve Head Start children's language competencies by targeting home literacy environment and approaches to learning. At a preliminary level, the study findings suggest that positive approaches to learning may compensate for a limited home literacy environment. Because positive approaches to learning can facilitate learning in other domains, for instance, language learning, this information may be useful for early educators in terms of promoting positive learning attitudes and predispositions toward learning.
