Missing data are a common occurrence in survey-based research studies in education, and the way missing values are handled can significantly affect the results of analyses based on such data. Despite known problems with performance of some missing data handling methods, such as mean imputation, many researchers in education continue to use those…

The primary purpose of a literature review is to assist readers in understanding the whole body of available research on a topic, informing readers on the strengths and weaknesses of studies within that body. It is defined by its guiding concept or topical focus: an account of what was previously published on a specific topic. This prevents…

The methods literature on research with children recognises the challenges of negotiating informed consent with this group. Special "child-friendly" techniques are advocated to overcome these challenges. We argue that, upon closer inspection, research with children foregrounds more fundamental problems with informed consent that are not easily…

The use of numerical/quantitative data in qualitative research studies and reports has been controversial. Prominent qualitative researchers such as Howard Becker and Martyn Hammersley have supported the inclusion of what Becker called "quasi-statistics": simple counts of things to make statements such as "some," "usually," and "most" more…

The purpose of this conceptual paper is to describe a design that mixes single-case (sometimes referred to as single-subject) and qualitative methods, hereafter referred to as a single-case mixed methods design (SCD-MM). Minimal attention has been given to the topic of applying qualitative methods to SCD work in the literature. These two…

While much has been written on the problems that can arise when interviewing respondents from a different social group, less attention has been paid to its potential benefits for the research process. In this paper we argue that, by being conscious of one's outsider status, an interviewer can use it as a tool through which to elicit detailed and…

As the educational research community has struggled with research issues over the last few decades, we have turned almost exclusively to epistemologically oriented methodology for answers. Implicit in this methodological discourse are three questionable presuppositions about the relationship between methods and methodology and between researchers…

Combining diverse methods in a single study raises a problem: What should be done when the findings of one method of investigation conflict with those of another? We illustrate this problem using an example in which three study phases--quantitative, qualitative, and intervention--were applied. The findings coming from the quantitative phase did…

This commentary considers some of the challenges of applying mixed methods research in undergraduate research degrees, especially in professions with a clinical health focus. Our experience in physiotherapy academia is used as an example. Mixed methods research is increasingly appreciated in its own right as a "third paradigm," however the success…

The comparability of experimental and comparison groups, problems in sampling and matching, existence of uncontrolled differences and their statistical treatment, and problems of client mobility and experimental control are discussed and illustrated by examples from an evaluation project. (Author)

This paper provides a framework for developing sampling designs in mixed methods research. First, we present sampling schemes that have been associated with quantitative and qualitative research. Second, we discuss sample size considerations and provide sample size recommendations for each of the major research designs for quantitative and…

Concludes that there is no evidence for differential validity in the Minnesota Multiphasic Personality Inventory (MMPI) between racial subgroups and that black norms for the MMPI are premature. Criticism of these findings is also presented. (Author/BEF)

The discussion of the gap between theory and practice has a long tradition in educational psychology and especially in research on learning and instruction. Starting with a short analysis of more or less elaborated approaches focusing on this problem, a complex procedure called "integrative research approach", specialized in reducing the gap…

This paper documents the creation of a procedural model for researching regional art history. It focuses on the region of Central Ohio and identifies art historical resources and a sampling of artists from 1945-1995. Topics discussed include: art history in Europe and in the United States; the problem of researching regional art history; review of…

Suggests that in publishing educational research results, the minority researcher should seek outlets which have maximum impact on policy implementations and decision making in addition to seeking those outlets which have maximum impact in his community. (Author/AM)
