Geometry is an important part of the mathematics curriculum. In the late 1950s, Pierre Van Hiele and Dina Van Hiele-Geldof developed a theory of learning geometry. Theory helps determine students' geometric thinking levels, design appropriate instruction for their level, and students move to the next level. This study aims to examine the studies…

This study provides a comparison of the results of latent class analysis (LCA) and mixture Rasch model (MRM) analysis using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th-grade mathematics section. The research study focuses on the comparison of LCA and MRM to determine if results…

When evaluators plan site-randomized experiments, they must conduct the appropriate statistical power analyses. These analyses are most likely to be valid when they are based on data from the jurisdictions in which the studies are to be conducted. In this method note, we provide software code, in the form of a SAS macro, for producing statistical…

Students' attitude towards science (SAS) is often a subject of investigation in science education research. Survey of rating scale is commonly used in the study of SAS. The present study illustrates how Rasch analysis can be used to provide psychometric information of SAS rating scales. The analyses were conducted on a 20-item SAS scale used in an…

The regression discontinuity design (RDD) has the potential to yield findings with causal validity approaching that of the randomized controlled trial (RCT). However, Schochet (2008a) estimated that, on average, an RDD study of an education intervention would need to include three to four times as many schools or students as an RCT to produce…

"The Spalding Method"[R] is a language arts program for grades K-6 that uses explicit, integrated instruction and multisensory techniques to teach spelling, writing, and reading. The program and its textbook, "The Writing Road to Reading," provide 32 weeks of lesson plans. Students work on program materials in spelling,…

This report describes how five states -- Alabama, Kentucky, Maryland, Tennessee and Texas -- made exceptional progress in student achievement during the first decade of the 21st century. State leaders in these states all realized early in the decade that they had a problem they wanted to address. They established a "plan" at the state…

This study examines trends in American students' growth trajectories in reading and math achievement over the past three decades. Drawing upon multiple sources of national assessment data, cohort analyses provide new evidence on the stability and change of national academic growth curves. The emerging trends imply a tripartite pattern where…

While most research on the benefits of afterschool programs has shown positive behavioral outcomes, the results on academic outcomes have been mixed. This study focused on academic outcomes to further explore whether students who regularly attended a school-based afterschool program showed greater academic gains than students who did not attend.…

In this report, Joan Herman, director for the National Center for Research, on Evaluation, Standards, & Student Testing (CRESST) recommends that the new generation of science standards be based on lessons learned from current practice and on recent examples of standards-development methodology. In support of this, recent, promising efforts to…

"Accelerated Reader"[TM] is a guided reading intervention used to supplement regular reading instruction in K-12 classrooms. Its aim is to improve students' reading skills through reading practice and quizzes on the books students read. The "Accelerated Reader"[TM] program calls for students to select and read a book and then…

Across the political spectrum, high-quality early care and education (ECE) is viewed as essential to educational reform. No ECE program can succeed without teachers who can establish warm and caring relationships with children, light the fires of children's curiosity and love of learning, and foster their development and readiness for school.…

When it comes to teacher preparation, the support provided to new teachers, and ongoing professional development for working teachers, Grades K-12 and the field of early care and education (ECE) are two very different worlds. While both worlds assume that teachers' classroom skills and behavior can be influenced at multiple points in time (through…

This paper aims to broaden the discussion about effective teacher preparation by exploring three hypotheses designed to expand the early care and education (ECE) research agenda: (1) Both the content and the method of delivery of an educational degree influence teacher practices; (2) Teachers' ability to apply knowledge and skills effectively…

Over 900 Texas teachers were surveyed on their perceptions of the Texas Assessment of Academic Skills (TAAS), which at the time of the survey was Texas's high-stakes achievement test. The sample included elementary, middle, and high schools within each of four test performance levels: exemplary, recommended, acceptable, and low performing.…
