This study examined differences in literacy development between five students attending whole language pre-first-grade classes and five students eligible for pre-first-grade classes but attending modified traditional first-grade classes. Differences between whole language pre-first-grade classes and modified traditional first-grade classes in use of literacy materials, teaching procedures, and amount of time spent on literacy were also examined. The procedures involved testing the subjects on reading and writing skills, observations of the pre-first-grade and first-grade classes, and analysis of subjects' writing samples.
