Research in fields other than education has found that studies with small sample sizes tend to have larger effect sizes than those with large samples. This article examines the relationship between sample size and effect size in education. It analyzes data from 185 studies of elementary and secondary mathematics programs that met the standards of…

Content analysis has dominated computer-mediated communication and educational technology studies for some time, and a review of its practices applied to online corpus of data or messages is overdue. We are confronted with complexity given the various foci, nuances and models for theorising learning and applying methods. One common suggestion to…

This article explores children's participation in research, from the perspectives of researchers who have conducted research with children. Researchers' reports, gained using an email interviewing method, suggest that children's participation rights are particularly compromised when the potential child participants are considered vulnerable and…

Presented at the quarterly meeting of the New York Area SAS Users-Group in December 2008. In virtually any research context, there is likely to be opportunity to apply mixed-models--of which repeated-measures, multilevel, hierarchical and random- and fixed-effect models are specific types-- that improve upon their traditional linear or generalized…

In this article, the authors share their views on the article by Dr. Radford, which raises a number of key issues that have a great impact on the future of postgraduate training and funding as well as on postgraduate students' future careers. The first issue relates to higher education in which the teaching at undergraduate level is evermore being…

In this article, the author seeks a middle path through which to traverse the "tricky ground" of Indigenous research; a middle path that will hopefully find "in-between spaces" open to new epistemological pathways, through which new voices and ideas can be heard within the social sciences and, in particular, within geography.…

I chronicle the changes in my research, especially those that have moved me closer to C. Wright Mills's call for a "sociological imagination" and Dell Hymes's reinvented anthropology. As I spend more time attempting to create and describe equitable educational environments and less time documenting educational inequality, I have adopted a version…

The latest national report card on higher education, as in the past, handed out a lot of "incompletes." Like the student who keeps forgetting to turn in that lab report, the grades can't be computed without all the data. There's a lot policy makers don't know about their states' higher-education performance, and the gaps in information limit the…

There has been criticism about STEM education not focusing enough on problem solving, especially in authentic real-world contexts which are most often associated to ill-structured domains. To improve education, it is essential that curricula bring students to high levels of cognitive development by exposing them to authentic problems.…

This review examines a research study that compares high school graduation rates of students who used vouchers to attend private high schools in Milwaukee and students who attended public high schools in that same city. The study reports that for the most recent year of data, a sample of voucher students had estimated graduation rates 12…

I argue in this article that recognizing the role of subjectivity and bringing in the researcher's positionality as a tool in the research process can not only enhance the ethical integrity of the research but also enhance both the research process and the analysis and interpretation of the data. Cultural studies theorists have long argued that…

From year to year, child welfare directors allocate resources in the hope that their efforts will improve children's outcomes. Recently, with the help of the federal government, states have invested significant resources in the sort of information technology needed to run a smarter, more accountable child welfare system. In addition, science has…

The interpretation of cognitive test scores often leads to decisions concerning the diagnosis, educational placement, and types of interventions used for children. Therefore, it is important that practitioners administer and score cognitive tests without error. This study assesses the frequency and types of examiner errors that occur during the…

This study compares three variations in how researchers construct middle childhood social networks: (1) with "friendships" or "affiliations" as a relational tie; (2) with children providing "self reports" of relationships, or in addition, "multi-informant reports" of relationships in which they are not involved; and (3) whether network computation…

This article examines the potential contradictions of conducting a collaborative self-study research project within a poststructural framework. It is a discussion about the use of theory in self-study research, rather than a report of research findings. The discussion is shaped through (re)consideration of a collaborative self-study doctoral…
