Evaluation of Earobics Step 1 in Low SES Minority Children & English Language Learners Jason Anthony Efficacy of computerized Earobics and Building Blocks instruc4on in various classroom contexts Jason Anthony Funding source: US DOE, Institute of Educational Sciences Early Education and Technology for Children Salt Lake City, Utah (April 3, 2011) Research Questions 1. Does Earobics improve literacy? 2. Does Building Blocks improve math? 3. Does the impact of Earobics vary as a function of classroom contexts? What did the computer tutors teach our children? Earobics step 1 teaches " Phonological Awareness " Alphabet knowledge " Sound discrimination " Memory for sounds What did the computer tutors teach our children? Building Blocks teaches " Shapes " Numeracy & Counting " Patterning " Arithmetic Sample Demographics Monolingual Eng.

Yes, Earobics is more beneficial in some classrooms 2. Which classrooms? 3. 2 patterns of findings • One pattern for literacy instruction • Another pattern for language instruction Growth in Blending by Frequency of Phonics Instruction and Group 43 Blending Raw Score 41 39 37 35 B.B.

Specifically they demonstrated quicker rates of learning PA, graphophonemic knowledge, and reading.

" More frequent oral language instruction is associated with slower rates of growth in phonological awareness and reading if children don’t receive supplemental Earobics instruction. " So if lots of oral language instruction slows literacy growth in the absence of supplemental Earobics instruction, should we do it?

High_Sgrpread 44 42 WAVE1 WAVE2 WAVE3 Conclusions " Building Blocks accelerated growth in Math " Earobics did not speed growth in PA or reading " Earobics children get more out of literacy instruction " Oral language Instruction speeds growth in vocab " Oral language Instruction slows growth in literacy, unless child receives supplemental PA intervention " Small group reading instruction improves literacy outcomes but slows growth in vocabulary. " Trade offs between what to teach " Trade offs less evident with supplemental intervention Limitations " Only results from 1st observation reported " Sample was all ethnic minorities from low SES " Building Blocks effects based on only 2 waves " Longitudinal follow-up needed to see if impacts last " computer interventions evaluated as standalone
