Randomized controlled trials (RCTs) are widely considered to be the gold standard in evaluating the impacts of a social program. When an RCT is infeasible, researchers often estimate program impacts by comparing outcomes of program participants with those of a nonexperimental comparison group, adjusting for observable differences between the two…

This study investigated whether students who engage in inquiry dialogue with others improve their performance on various tasks measuring argumentation development. The study used an educational environment called Philosophy for Children (P4C) to examine specific theoretical assumptions regarding the role dialogic interaction plays in the…

The authors developed a demonstration with two similar setups that provide students with both the prior experience to form an expectation and the discrepancy to grab their attention. They follow the demonstration with a structured exploration format that gives students a method for experimenting to find the one built-in difference (i.e., the…

In this paper the authors extend recent work on mediation in a multilevel setting and on causal inference under interference among units to develop a template for the mediation analysis of group randomized educational interventions. The present work will contribute to the literature on interference, in particular on interference in the context of…

The purpose of this study was to explore whether there was a significant correlation between vocabulary and reading comprehension in terms of text types as well as whether the vocabulary was a predictor of reading comprehension in terms of text types. In this regard, the correlational research design was used to explain specific research…

One of the most widely used commercially available systems incorporating benchmark assessment and training in differentiated instruction is the Northwest Evaluation Association's (NWEA) Measures of Academic Progress (MAP) program. The MAP program involves two components: (1) computer-adaptive assessments administered to students three to four…

The Louisiana Scholarship Program (LSP) is a statewide initiative offering publicly-funded vouchers to enroll in local private schools to students in low-performing schools with family income no greater than 250 percent of the poverty line. Initially established in 2008 as a pilot program in New Orleans, the LSP was expanded statewide in 2012.…

The concept of "implementation fidelity" is broadly used to capture the extent to which an intervention is executed as intended by the designers of the intervention (Century, Rudnick, & Freeman, 2010; Huntley, 2005, McNaught, Tarr, & Sears, 2010, Munter, 2010). Though implementation fidelity instruments are often used to assess…

The purpose of this quantitative study was to investigate whether or not informational writing in the science curriculum would impact fifth grade students' science achievement and conceptual understanding. The population of this study came from a metropolitan school district in the state of Georgia for school year 2012-2013. The quantitative data…

Objectives: Group-randomized designs are well suited for studies of professional development because they can accommodate programs that are delivered to intact groups (e.g., schools), the collaborative nature of professional development, and extant teacher/school assignments. Though group designs may be theoretically favorable, prior evidence has…

The meaning of fractions with integer multiplication is something that is difficult to understand by students. They tend to think that the product it produces a larger number, while the multiplication of fractions with integers, the result can be any number larger or smaller. This study is a research design that aims to develop a local…

Randomized trials of educational interventions often face logistical hurdles (Cook, 2002). For example, sometimes they are prevented from reaching their full-term. This would happen if, as a condition of participation, subjects insist on receiving the treatment program within a certain timeframe. This timeframe may be shorter than the full-term…

This issue brief focuses on one particular report, released in September 2009, that has been widely cited by charter school advocates because it appears to show remarkable results. In the report, "How New York City's Charter Schools Affect Achievement," Stanford University professor Caroline Hoxby and her colleagues Sonali Murarka and…

Reader response theory and research on book interest underpinned a study of the appeal of celebrity-authored children's storybooks to elementary school students. We engaged fifth-grade students in selecting and reading from a set of 41 celebrity-authored books and completing reader response forms. Utilizing the survey research design and a…

This study examines the incentive effects of North Carolina's practice of awarding performance bonuses on test score achievement on the state tests. Bonuses were awarded based solely on whether a school exceeds a threshold on a continuous performance metric. The study uses a sharp regression discontinuity design, an approach with strong internal…
