The present paper reports a cluster randomized control trial evaluation of teaching using ABRACADABRA (ABRA), an Misc evidence-based and web-based literacy intervention (http://abralite.concordia.ca) with 107 kindergarten and 96 grade 1 children in 24 classes (12 intervention 12 control classes) from all 12 elementary schools in one school district in Canada.Children in the intervention condition received 10-12 hours of whole class instruction using ABRA between pre- and post-test.

Hierarchical linear modeling of post-test results showed significant gains in letter-sound knowledge for intervention classrooms over control classrooms.In addition, medium effect Target Holders sizes were evident for three of five outcome measures favoring the intervention: letter-sound knowledge (d = +.66), phonological blending (d = +.52), and word reading (d = +.

52), over effect sizes for regular teaching.It is concluded that regular teaching with ABRA technology adds significantly to literacy in the early elementary years.
