I) Analyzing and interpreting data
Dr. Fuller wanted to study whether Latino children’s English ability affects their
learning outcomes in kindergarten.
For this study Dr. Fuller analyzed data from the Early Childhood Longitudinal Study (ECLS-K) Kindergarten Class of 1998-99, sponsored by the National Center of Education Statistics..Using a multistage probabilistic sampling design, the ECLS-K is based on a nationally representative sample of approximately 20,000 kindergarteners. Dr. Fuller analyzed a randomly selected subsample of Latino children.
The variables analyzed are the following:
1) Math test score in kindergarten: Range from 6 to 84 points. Math tests are curriculum-based assessments based on the National Assessment of Educational Progress framework of content areas and domains.
2) English ability (OLDS), which was measured by students’ test scores on the English
Oral Language Development Scale taken in the fall of kindergarten. The ECLS-K study used the OLDS to determine whether students from non-English
speaking homes had the necessary minimum English skills to take cognitive assessments
in English. The OLDS scores range from 0-60 points.
Given that socioeconomic status is such a strong predictor of learning outcomes, he decided to include this variable in his analyses.
3) Students’ socioeconomic status (SES) is a standardized measure with a mean of 0 and
a standard deviation of 1. It represents student families’ socioeconomic status based on
mothers’ and fathers’ education, mothers’ and fathers’ occupational status, and household income, measured in the fall of kindergarten and in the spring of first grade.
