Traditional efforts to increase teacher quality through professional development (PD) have been largely ineffective. A growing body of research on teacher coaching provides strong evidence of its effectiveness as a PD tool, although it also raises difficult questions about whether and how to implement coaching programs at scale. Key considerations…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study designed to measure trends in mathematics and science achievement at grades 4 and 8, as well as to collect information about educational contexts (such as students' schools, teachers, and homes) that may be related to student achievement. TIMSS has…

In an examination of the conditions required for the successful implementation of performance assessment, the authors draw on a range of personal experience and other insights to guide practitioners and policymakers. Building on the authentic assessment work of the Boston Pilot Schools (CCE 2004), in 2008 the Center for Collaborative Education…

Policies aimed at both reducing the costs associated with schooling (particularly through fee-free education) and decentralising responsibility for education delivery have become a central part of international education doctrine. This article draws on the 'politics of scale' literature to highlight how these education reforms are contested at…

Molenaar extended Mokken's original probabilistic-nonparametric scaling models for use with polytomous data. These polytomous extensions of Mokken's original scaling procedure have facilitated the use of Mokken scale analysis as an approach to exploring fundamental measurement properties across a variety of domains in which polytomous ratings are…

Questionnaire refinement and a process for selecting items for elimination are important tools for survey developers. One of the major obstacles in questionnaire refinement and elimination in surveys lies in one's ability to adequately and appropriately reconstruct a survey. Often times, surveys can be long and strenuous on the respondent,…

In every school district across the country, every year, initiatives are adopted with the goal of improving the literacy performance of young students, and, just as frequently, these initiatives fail or quickly become passing fads. In this article, Rodgers reviews literature related to scaling educational innovations and describes challenges and…

As an alternative to common-item equating when common items do not function as expected, the single-group growth model (SGGM) scaling uses common examinees or repeaters to link test scores on different forms. The SGGM scaling assumes that, for repeaters taking adjacent administrations, the conditional distribution of scale scores in later…

It is important to assess periodically how introductory textbooks portray our discipline because introductory psychology is the most popular psychology course, almost all teachers use textbooks for it, and textbooks play a major role in defining the course for students. To do so, past studies have used textbook citation analyses. We analyzed…

With close to 50 million children attending 98,000 public schools in the United States, the public school classroom continues to be an essential locus of change that, if improved at scale, could increase educational and life outcomes of many young people. Improved student learning requires an improved instructional core and school leaders are…

This article tests whether collecting pile-sort data online produces results similar to those obtained with face-to-face methods. We collected pile sorts from 227 university students in the cultural domain of emotions. To test for mode and design effects, we randomly assigned participants to face-to-face or internet modes and to either a 15- or…

Spatial skills are consistently linked to mathematical reasoning, and are sensitive to intervention. One important spatial skill is spatial scaling. We evaluated whether (1) a playful scaling game might promote learning by providing feedback during play, and (2) spatial scaling is related to number-line estimation based on the mutual reliance on…

Spatial skills are consistently linked to mathematical reasoning, and are sensitive to intervention. One important spatial skill is spatial scaling. We evaluated whether (1) a playful scaling game might promote learning by providing feedback during play, and (2) spatial scaling is related to number-line estimation (NLE) based on the mutual…

The Questionnaire on Teacher Interaction (QTI) is a teacher--student relationship measure whose underlying two-dimensional structure is represented in a circumplex model with eight sectors. Using Smallest Space Analysis (SSA), this study examined the circumplex structure of the Chinese version of the QTI among a convenience sample of 731…

This article presents findings from a study of the minimum conditions needed to scale a previously successful model of high school reform in New York City. Most studies of scale work backward to identify conditions that were in place when scale was successful, rather than identifying those that were minimally required, and thus more likely to be…
