The spiral bianshi curriculum, an improvement on bianshi teaching developed by Gu (2000) and in line with Marton's theory of variation (Marton & Booth, 1997), was tried out in a primary school in Hong Kong. This improved theoretical framework for the spiral bianshi curriculum comprises four types of bianshi problems--the inductive bianshi, the…

Background: This meta-analysis of interventions with challenging behaviour in children with disabilities updates a comprehensive meta-analysis that previously addressed reported standards of practice and effectiveness of different strategies. Method: Four effect-size algorithms were calculated for published intervention cases, and results analysed…

Teaching foreign languages at distance is now becoming widespread; so is the need for evaluating online language courses. This article discusses an example of a framework that was applied to evaluate an online English as a foreign language (EFL) course at a Middle Eastern university. The development of the framework investigated areas of interest…

Sulfate reducing bacteria have been shown to be effective at treating acid mine drainage through sulfide production and subsequent precipitation of metal sulfides. In this laboratory experiment for undergraduate environmental chemistry courses, students design and implement a set of bioreactors to remediate acid mine drainage and explain observed…

This study extends the research on issues of trust in family-professional relationships by more fully examining, within a qualitative research design, the nature of trust between parents of children with disabilities and school personnel. The authors examined the trust-related perspectives of 16 mothers of children with various disabilities at all…

The American Lung Association's Not On Tobacco (N-O-T) program is federally recognized as an accessible and effective option for teen smoking cessation. The program is the most widely used teen smoking cessation program in schools and communities across the U.S. Over a decade of research demonstrates the program's solid evidence base, with…

Objective: To describe promising recruitment and retention strategies for transient Latino populations, assisting investigators who work with this population in their research design and implementation. Methods: Strategies in recruitment and retention from a year-long intervention in children and their families are described. Results: Of the 159…

Pretest-posttest experimental designs are often used in randomized control trials (RCTs) in the education field to improve the precision of the estimated treatment effects. For logistic reasons, however, pretest data are often collected after random assignment, so that including them in the analysis could bias the posttest impact estimates. Thus,…

This study examines the reporting of power analyses in the group randomized trials funded by the Institute of Education Sciences from 2002 to 2006. A detailed power analysis provides critical information that allows reviewers to (a) replicate the power analysis and (b) assess whether the parameters used in the power analysis are reasonable.…

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.…

Multiple methods are vital to understanding development as a dynamic, transactional process. This article focuses on the ways in which quantitative and qualitative methodologies can be combined to enrich developmental science and the study of human development, focusing on the practical questions of "when" and "how." Research situations that may…

Collaborative research often refers to collaboration among the researcher and the participants. Few studies investigate the collaborative process among researchers themselves. Assumptions about the qualitative research process, particularly ways to establish rigor and transparency, are pervasive. Our experience conducting three collaborative…

This article considers the underlying assumptions related to the use of random assignment in educational research and evaluation; more specifically, the ability of random assignment to create similar comparison groups for the purpose of determining the effectiveness of educational programmes. In theory, randomly assigning individuals to comparison…

Sharpening our approaches to methodology in self-study research can strengthen our work and clarify questions that arise for readers unfamiliar with this research genre. Our article considers three methodologies--narrative, auto-ethnography and self-study--that privilege self in the research design, believing that addressing self can contribute to…

Increasingly, instructional technology research and design grounded in field-based data collection takes place in classrooms, after school programs, and informal learning settings. One byproduct of a commitment to naturalistic, unfolding inquiry in authentic settings is a significant degree of uncertainty, a situation oftentimes provoking ethical…
