Immigrant mothers in "new immigrant families" (one spouse is a marriage immigrant) in Taiwan are popularly viewed as culturally deficient and as not having knowledge to teach children literacy. Multiple-case study methods were adopted. Thirteen Vietnamese mothers participated in this study. The lens of "funds of knowledge" was used to examine household knowledge and skills. Unique immigrant knowledge funds, including multilingual experiences, transnational experiences, and a cultural value--having good manners, are transmitted in these families. However, these funds of knowledge are often not recognized and valued by immigrant mothers and schools in helping their children to learn literacy. Hopefully this study would draw attention on the cultural resources of new immigrant families and shed light on the development of a culturally responsive literacy curriculum.
