Individual growth curves yield insights about growth that are not available from any other methodology; and developmental scales based on conjoint measurement models provide unique interpretive advantages for investigations of academic growth. The advantages are apparent when: (1) 15 consecutive statewide reading growth curves are annotated with…

A vertical scale, in principle, provides a common metric across tests with differing difficulties (e.g., spanning multiple grades) so that statements of "absolute" growth can be made. This paper compares 16 states' 2007-2008 effect size growth trends on vertically scaled reading and math assessments across grades 3 to 8. Two patterns…

The McKinney-Vento Homeless Education Assistance Improvements Act of 2001 (MCKV), which provides funds to local educational agencies (LEAs), is almost a decade old, yet no evaluations of its academic effectiveness have been reported. Using a systems theory framework, the authors answer the question of whether homeless students in grade 6 from LEAs…

Is a popular innovation for increasing human capital in the teaching profession--competitive college scholarships for teachers--effective? The authors show that one large and long-standing merit-based scholarship program (a) attracts teacher candidates who have high academic qualifications; (b) yields graduates who teach lower performing students,…

Congressional concern about homeless students resulted in the McKinney-Vento Act (MCKV) in 2001, which provides funds to local educational agencies (LEAs). MCKV is almost a decade old, yet no evaluations of its academic effectiveness have been reported. Using a systems theory framework, this study answered research questions (RQs) involving…

In 2008-09, results from End-of-Grade (EOG) reading and mathematics tests in WCPSS continued to demonstrate an upward trend across grade levels and student subgroups. Disaggregation of results by ethnicity, income level, disability status, and English proficiency status showed that achievement gaps between historically underperforming subgroups…

A study examined middle grades students' learning of concepts related to the use and interpretation of graphs. Subjects of the study were 76 sixth-grade students in 3 different mathematics classes in a central North Carolina middle school. The first two parts of the written instrument were administered as both a pretest and a posttest, using line…
