Recent research suggests that the examination of students' work may lead to changes in teaching practice that are more effective in terms of students' mathematical learning. However, the link between the examination of students' work and the teachers' actions in the classroom is largely unexamined, particularly at the secondary level. In this…

Reporting and interpreting (corrected) effect size indices can help readers of scientific reports understand the importance of those results more fully instead of just determining the likelihood of results assuming the null hypothesis. This study explored the frequency of effect reporting and interpretation in quantitative studies in Communication…

This guide provides students with practice for all the major types of graphs they are likely to encounter. It includes information on graphs of various families of algebraic functions; bar, line, and circle graphs; the creation, reading, and interpretation of graphs; and the use of graphing calculators. (MVL)

Presents two viewpoints about the use and interpretability of beta weights in educational research: (1) that beta weights should be interpreted as a logical index of the importance of individual predictors within the context of the entire set of predictors; and (2) that interpretation requires certain cautions and conditions. (SV)

A procedure is presented to transform an n-dimensional scatter diagram into a two-dimensional scatter diagram while preserving proximity relationships between points. This procedure can help in the presentation and interpretation of multivariate results. (Author/SLD)

This study was an attempt to replicate a previously reported quantitative trait loci association between general cognitive ability and a marker identified as EST00083 (P. Skuder et al., 1995). The association remained significant for 51 high and 51 average IQ child subjects but not for 40 extremely high and 50 average IQ subjects. Implications are…

Provides information regarding the National Educational Longitudinal Study database that was used for many of the studies in this volume. Provides relevant background and instructions so that others may use this resource from the National Center for Education Statistics. (Author/EV)

Investigates 10th grade students' ability to handle data and interpretation by using a variety of tasks. Discusses the importance of developing student discussion as a route to better conceptual understanding of data presented in graphical form. (Contains 15 references.) (Author/YDS)

The present article presents a tutorial on how to estimate and interpret various effect sizes. The 5th edition of the Publication Manual of the American Psychological Association (2001) described the failure to report effect sizes as a "defect" (p. 5), and 23 journals have published author guidelines requiring effect size reporting. Although…

This guide is designed to inform school directors about the value of a data dashboard and to provide information on how districts can create a data dashboard for school directors. A data dashboard is a tool for viewing and analyzing student achievement and performance data. Key data for monitoring student achievement and directing policy level…

This handbook was developed for high school teachers looking for new sources of timely information and ways to make courses more engaging and relevant to students. The American Community Survey (ACS) provides a wide online array of social, economic, and demographic information about the nation, states, and local communities. These data can be…

Qualitative researchers in school psychology have a multitude of analyses available for data. The purpose of this article is to present several of the most common methods for analyzing qualitative data. Specifically, the authors describe the following 18 qualitative analysis techniques: method of constant comparison analysis, keywords-in-context,…

This paper extends earlier research into the responses of local authorities and schools to the requirements of the Race Relations (Amendment) Act 2000 (RRAA) in relation to minority ethnic pupils and exclusion practices. The original study drew on evidence from national exclusions data, a wide range of official documentation and visit data from 85…

To ensure accurate interpretation of research findings, researchers should report details about their research design, data collection method, and response rates when presenting findings from survey research. A review of 100 peer-reviewed articles reporting the results of survey research on K-12 schools with principals as the designated…

The last significant review of research about transformative learning was in 1998 and was mostly focused on unpublished dissertations. In response, this paper reviews an exhaustive body of research conducted since that time, involving 40 studies, published in peer-review journals with a lens of analysis of new findings and insights on…
