The Common Core State Standards (CCSS) in English and math were finalized in 2010 and, as of July 2012, have been adopted in full by 45 states. These standards provide a framework that is intended to ensure that all students who graduate from high school in the United States have attained the knowledge and competencies that prepare them well for…

Partnership for Assessment of Readiness for College and Careers (PARCC) member states regard assessments as tools for enhancing teaching and learning, and are committed to providing all students, including but not limited to, students with disabilities, English learners, English learners with disabilities, and underserved populations with…

The U.S. began a new national standards movement in the area of K-12 science education curriculum reform in the 1980s known as "Science for All" to develop a population that is literate in economic and democratic agendas for a global market focused on science, technology, engineering, and mathematics (STEM) (Duschl, 2008). The National…

A multilevel latent transition analysis (LTA) with a mixture IRT measurement model (MixIRTM) is described for investigating the effectiveness of an intervention. The addition of a MixIRTM to the multilevel LTA permits consideration of both potential heterogeneity in students' response to instructional intervention as well as a methodology for…

"IXL Learning" contracted with Empirical Education to study the effectiveness of "IXL Math" in Beaverton School District. During the 2011-2012 year, "IXL Math," an interactive, cloud-based practice environment, was used to supplement instruction in two elementary/middle schools. This study focused on 4th and 5th grade…

Gaps in achievement test scores continue to exist in students depending upon race, gender, income, and ethnicity according to the Center on Education Policy (CEP), an advocate for public schools. School districts and schools are struggling to close the achievement gap that exists. In the 2010-2011 school years, 34.4% of African American students…

This manual has been produced to familiarize data users with the design, and the procedures followed for data collection and processing, in the base year and first follow-up of the High School Longitudinal Study of 2009 (HSLS:09), with emphasis on the first follow-up. It also provides the necessary documentation for use of the public-use data…

It also provides the necessary documentation for use…

This study was designed to determine if differences in student achievement existed between traditional public and charter high schools in the District of Columbia. The study examined student outcomes on the standardized state test in reading and math from 2006 to 2010 utilizing descriptive statistics, crosstab analysis, chi-square tests…

Peruvian students at both the elementary and the secondary level have shown poor results in evaluations of mathematics achievement in recent years. In addition, research has found that teachers are not implementing the curriculum as expected; traditional practices of teaching are still present in classrooms. These problems have driven a school…

This paper explores the outcomes of the first year of the implementation of a mathematics program ("Representations, oral language and engagement in Mathematics": RoleM) which is framed upon research relating to effectively supporting young Indigenous students' learning. The sample comprised 230 Indigenous students (average age 5.76…

In this technical report, we describe the results of a study of mathematics items written to align with the Common Core State Standards (CCSS) in grades 6-8. In each grade, CCSS items were organized into forms, and the reliability of these forms was evaluated along with an experimental form including items aligned with the National Council of…

The study reviewed in this report examined the effectiveness of the "Milwaukee Parental Choice Program" ("MPCP"), which provides vouchers for low-income students to attend private schools. The study analyzed data on about 600 students who were given "MPCP" vouchers in the 2006-07 school year. The authors created a…

Over the past decade, educational policy trends have shifted to a focus on examining students' growth from kindergarten through twelfth grade (K-12). One way states can track students' growth is with a vertical scale. Presently, every state that uses a vertical scale bases the scale on a unidimensional IRT model. These models make a…

Quality teaching requires a strong practice of collaboration, an essential building block for educators to improve student achievement. Researchers have theorized that the implementation of a professional learning community (PLC) with resultant collaborative practices among teachers sustains academic improvement. The problem addressed specifically…
