School Services Projects: High School Project Results

 

High School One
From 1999-2000, a study to examine the effectiveness of the Seeing Stars® program was conducted at a high school in California. Thirty-eight students with decoding issues were randomly assigned to experimental (Lindamood-Bell) and comparison (normal language arts curriculum) conditions. All students were pre-tested on a battery of nationally normed assessments, received instruction for approximately 12 weeks (Lindamood-Bell® students averaged 52 hours of instruction), and were re-tested on the same battery. Average pre-test performance on every test administered was statistically similar between the two groups, thus allowing for a comparison of average gains. The following illustrates comparative gains between the two groups.

Standard Score Gains

The Lindamood-Bell® students outperformed (p < .05) the comparison students on the average decoding composite across several tests—word recognition, spelling, word attack, reading rate, and reading accuracy.

 

High School Two
The following results were from twenty-eight decoding focus students at a high school in Alaska for the 2003-2004 school year. Their average age was 15 years-old and they received an average of 70 hours of instruction. All of the following results from pre- to post-test are statistically significant (p < .05).
