There is a statistically significant relationship between higher reading scores and larger school media center budgets. Students taking the reading tests in grades 5, 7, 8, and 10 scored between 3 and 6 points higher on those tests in schools with higher media center expenditures.
Increases in eleventh grade reading scores are usually reported by Michigan high school libraries that have: higher numbers and weekly hours of librarian and total library staff; more total weekly hours of operation, and more weekly hours for flexible access/scheduling; librarian spending more time supporting school computer networks; larger collections of print volumes and video materials; and access to more computers—both in the library and throughout the school—that provide links to Access Michigan, library catalogs and licensed databases, and the Internet and the World Wide Web; and more frequent individual visits to the library [#9, #10]; and more money for library operations [#13].
For Michigan middle schools, seventh grade reading test scores usually rise as school libraries report:high numbers and weekly hours of librarian and total library staff;offering more weekly hours for flexible access/scheduling;librarians spending more time planning and teaching cooperatively with classroom teachers, and providing in-service training to teachers;larger collections of print volumes and video materials;access to more library and school computers that connect to Access Michigan, library catalogs and licensed databases, and the Internet and the World Wide Web;more frequent individual and group visits to the library; andspending more on library operations.
Both elementary and middle schools tended to perform better on tests where LMSs took the initiative, on at least a weekly or monthly basis, to provide their teachers with resources needed to design instruction.
Across grade levels, schools tended to perform better on the ISTEP+ [Indiana Statewide Testing for Educational Progress-Plus] tests where there were better-staffed, better-stocked, and better-funded school library programs.
…[R]esponding high schools report 16 weekly group visits, 10 of which are for information literacy instruction… For high schools that average more individual and group visits as well as more group visits for information literacy instruction, eleventh-grade ACT score gains averaged three to five percent over schools with less frequently visited libraries.
At the high school level, ACT scores average almost seven percent higher for schools [that] spend more on their libraries compared to those that spent less.
The wider spectrum of activities involved in true collaboration between school librarians and classroom teachers demonstrates an impact at the high school level, particularly through the links between those activities and eleventh-grade test scores. On a weekly basis, at the typical responding high school, library staff spends:three hours identifying materials for teacherstwo hours planning with teachers,one hour motivating students to read,one hour teaching with teachersalmost an hour serving on school committees, andhalf an hour meeting with library staff from another school or districtWhen library staff spends more time on these activities, ACT scores increase an average of three to four percent over the scores for schools with less collaborative library staff.
At every grade level, schools with more library and library-connected computers—particularly, in the latter case, Internet computers relative to the school’s enrollment—average higher test scores. The presence of more library computers is associated with percentage increases of:8 percent for fifth-and-eighth grade ISAT reading performancealmost 11 percent for eighth-grade ISAT writing performancejust over 5 percent for eleventh-grade ACT scores.
Between the elementary and middle school levels, there was a similar increase in the strength of the relationship between library spending and writing performance. Elementary schools that spend more on their libraries average almost 10 percent higher writing performance, and middle schools that invest more in their libraries average almost 13 percent higher writing levels.
