The purpose of this study is to investigate characteristics of limit concepts through the simultaneous use of historical and experimental epistemologies. Based on a historical epistemology which is an investigation of historical developments in a mathematical concept raised in the history of mathematics, four different developments of limit…

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…

What happens when teachers start to observe each other's classes? How do teachers make meaning of observing and being observed? What effects, if any, does requiring peer observation have on the teaching community? This research explores these questions in a qualitative study of peer observation of teaching (POT) in the 2nd-12th grades of an…

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…

The goal of this study was to develop a classification for a range of discourse patterns that occur in text-based asynchronous discussion forums, and that can aid in the distinction of three modes of discourse: knowledge sharing, knowledge construction, and knowledge building. The dataset was taken from Knowledge Forum® databases in the Knowledge…

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,…

For pre-service teachers (PSTs) who have been exposed to traditional approaches, teacher education courses can be a revelatory experience in their development as educators. This study explores if Canadian upper elementary/lower secondary (grades 4-10) PSTs change their beliefs about mathematics teaching as a result of taking a mathematics methods…

This paper summarizes the historical and legislative backgrounds leading to statewide testing of health-related physical fitness in Texas children grades 3-12 as mandated by Texas Senate Bill 530. The rationale and goals for an associated research project (the Texas Youth Fitness Study, funded by the Robert Wood Johnson Foundation) to evaluate…

In recent years, the regression discontinuity design (RDD) has gained widespread recognition as a quasi-experimental method that when used correctly, can produce internally valid estimates of causal effects of a treatment, a program or an intervention (hereafter referred to as treatment effects). In an RDD study, subjects or groups of subjects…

This technical report describes the conceptual foundation and measurement properties of the Reading Inventory and Scholastic Evaluation (RISE). The RISE is a 6-subtest, Web-administered reading skills components battery. The theoretical and empirical foundations of each subtest in the battery are reviewed, as well as item designs. The results…

"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,…

"Repeated reading" is an academic practice that aims to increase oral reading fluency. "Repeated reading" can be used with students who have developed initial word reading skills but demonstrate inadequate reading fluency for their grade level. During "repeated reading," a student sits in a quiet location with a…

Close reading is an instructional practice that has gained attention of late. It involves reading a complex text, annotation, and repeatedly reading to answer text-dependent questions. Although there are a number of recommendations for the use of close reading, there has not been a systematic analysis of student or teacher perceptions of this…

This groundbreaking study is the first ever to examine the achievement of high-performing students over time "at the individual level". It poses--and seeks to answer--this straightforward question: Do students who outscore their peers on standardized achievement tests remain at the top of the pack year after year? Put differently, how many "high…

This mixed design study investigated the predictive and instructional uses of two different types of interim mathematics assessments given in two different districts. One district administered the same summative type of assessment three times a year, while the other district administered a different interim assessment after six-week intervals of…
