In her book, Dancing With Words, researcher and author Marilyn Daniels shares that research demonstrates when signing is added to preschool curriculum, children not only find signing fun, but also, there is “significant improvement in receptive English vocabulary” and children retain information for a longer period of time. Daniel says, “vocabulary gains made in their pre-kindergarten years sustained throughout their kindergarten year and remained with them.”
