The participants included 128 kindergartners and 64 mothers who were randomly divided into four groups: independent reading of the e-book with a dictionary; joint mother¨Cchild reading of the e-book without a dictionary; joint mother¨Cchild reading of the e-book with a dictionary, and independent reading of the e-book without a dictionary (control). For each target word, the dictionary presented (1) word meaning, (2) word meaning within the story context, and (3) a combined meaning. Pre- and posttests included receptive and expressive understanding of the dictionary words. E-books were read four times. Reading the e-book with a dictionary and maternal mediation was the most effective for receptive and expressive word learning, followed by independent reading with the dictionary. Mothers who read the e-book with a dictionary mediated at a higher level than mothers who read without a dictionary. The intervention contributed to advancement in learning new words beyond children¡¯s initial vocabulary level.
