The Impact of School Library Media Centers on Academic Achievement. ERIC Digest.
Advocates of school library media programs have long been convinced of the relationship between quality library media programs and academic achievement. Most studies of this relationship were conducted between 1959 and 1979, were limited in scope, and usually used a small number of subjects in a limited geographical area. This study was designed both to update the existing research and to examine the relationship between library media programs and student achievement.METHODOLOGY
Ideally, schools included in the sample for a study such as this would be selected on a random, stratified, or quota basis. None of these sampling designs was possible, because schools included in the sample had to have library media centers that responded to the 1989 survey of school library media centers in Colorado and had to use the Iowa Tests of Basic Skills (ITBS) or Tests of Achievement and Proficiency (TAP). These data were available for only 221 of 1,331 public elementary and secondary schools in Colorado during the 1988-89 school year. The study relied entirely upon available data about school library media centers and their school and community contexts to predict norm-referenced test scores.FINDINGS
Findings of this study provided bases for measuring the relative impact of potential predictors on academic achievement. Correlation analysis of community variables identified the following relationships:* Rural and urbanized populations within school districts are almost mutually exclusive. In addition, there is little variation between districts that are 100 percent rural and 100 percent urbanized.* Where more adults have graduated from high school, family incomes are higher.* Where more
