Previous studies with English-speaking families in the North American context demonstrated that home literacy practices have positive influences on children's literacy acquisition. The present study expands previous studies by examining how home literacy practices are related to "growth trajectories" of emergent literacy skills (i.e., vocabulary, letter-name knowledge, and phonological awareness) and conventional literacy skills (i.e., word reading, pseudoword reading, and spelling), and by using data from "Korean" children and families (N = 192). The study revealed two dimensions of home literacy practices, home reading and parent teaching. Frequent reading at home was positively associated with children's emergent literacy skills as well as conventional literacy skills in Korean. However, children whose parents reported more frequent teaching tended to have low scores in their phonological awareness, vocabulary, word reading and pseudoword reading after accounting for home reading. These results suggest a bidirectional relationship between home literacy practices, parent teaching in particular, and children's literacy skills such that parents adjust their teaching in response to their child's literacy acquisition. Furthermore, cultural variation in views on parent teaching may explain these results.
