We examine the effect of direct and indirect teaching of vocabulary and word reading on pre-kindergarten and kindergarten children following use of an electronic storybook (e-book). The children in each age group were randomly assigned to an intervention group which read the e-book or to a control group which was afforded the regular school program. The e-book included words with meaning support and words with no support. Children who read the e-book exhibited progress in the meaning and reading of the words supported directly by the computer compared to the control group. No such progress was observed for words without direct support. No differences appeared in the progress between the two age groups and no interaction was found between age and type of word support.
