Standardized assessment is the government measurement of academic success in Texas. Currently, students in Grades 3-11 participate in the State of Texas Assessments of Academic Readiness (STAAR) as a measure of their comprehension of the state standards. In high school, students are required to pass the high school STAAR End of Course test in…

Little is known empirically about intraclass correlations (ICCs) for multisite cluster randomized trial (MSCRT) designs, particularly in science education. In this study, ICCs suitable for science achievement studies using a three-level (students in schools in districts) MSCRT design that block on district are estimated and examined. Estimates of…

A cluster-randomized trial (CRT) relies on random assignment of intact clusters to treatment conditions, such as classrooms or schools (Raudenbush & Bryk, 2002). One specific type of CRT, a multi-site CRT (MSCRT), is commonly employed in educational research and evaluation studies (Spybrook & Raudenbush, 2009; Spybrook, 2014; Bloom,…

This investigation addressed the hypothesized effects of the proportional size of a district's special education population on the overall student achievement in selected school districts in Texas. The size of a district's special education population (independent variable) was compared to districts' achievement (dependent variables) in order to…

The trend and demand for virtual education has grown nationwide. With an increase in students choosing this type of education, inevitably the demand for schools of this type of educational instruction has increased in number. The purpose of this study is to determine the extent of the relationship between virtual school size and student…

The purpose of this study is to examine the relationship between virtual school size and student achievement in virtual schools in a southwestern state. Enrollment size and the following areas were studied in an attempt to determine student achievement: STAAR English Language Arts/Reading, STAAR Math, STAAR Science, and STAAR Social Studies…

There is a need for a musical ensemble study that can describe the idiosyncratic, authentic movements that choral musicians make in a performance setting. In addition, it could benefit teachers to know whether those who score highest on a measure of expressive performance also tend to be strong performers. If this is the case, then the link…

This report reviews Advanced Placement (AP) and International Baccalaureate (IB) examination participation and performance in Texas during the 2009-10 school year. Campus-, district-, and state-level examination results for students in Texas public schools are presented, as well as state-level examination results for students in Texas public and…

Under the federal No Child Left Behind Act of 2001 (NCLB), standardized test scores are the indicator used to hold schools and school districts accountable for student achievement. Each state is responsible for constructing an accountability system, attaching consequences--or stakes--for student performance. The theory of action implied by this…
