Bridging the Student Achievement Gap in Science.
Miller-Whitehead, Marie
The relationship between school system financial and demographic data and student achievement on the science subsection of the Tennessee statewide standardized test was studied to determine if systems that served large numbers of low income students had been as successful as more affluent systems in improving student achievement. System-level data used consisted of Tennessee science scale scores for grades 3 through 8 for 1998, per pupil expenditure, per capita income, percent of students on free and reduced lunch, percent of ethnic group students, and percent of schools in the system meeting state class size guidelines. A hierarchical regression analysis was conducted with variables regressed on student scale scores on the 1998 test. The resultant equation yielded a multiple "R" of 0.82 and an adjusted "R squared" of 0.57, with percent of students on free and reduced lunch accounting for 55% of variability. Across grades 3 through 8, percent of students on free and reduced lunch accounted for the majority of unexplained variance in science scale scores. In a second procedure, for students in grade 5, the same variables regressed on grade 5 science scale score achievement resulted in a formula that yielded a multiple "R" of 0.81 and an adjusted "R squared" of 0.53. At grade 5, percent of students meeting class size standards accounted for the greatest amount of explained variability in science scale scores, with ethnicity marginally significant. Per pupil expenditure had a positive effect on the science scale score achievement for grade 5 students. An appendix maps science scale score trends.
