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 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…

Selection bias is a problem for mathematics education researchers interested in using observational rather than experimental data to make causal inferences about the effects of different instructional methods in mathematics on student outcomes. Propensity score methods represent 1 approach to dealing with such selection bias. This article…

Resampling methods including randomization test, cross-validation, the jackknife and the bootstrap are widely employed in the research areas of natural science, engineering and medicine, but they lack appreciation in educational research. The purpose of the present review is to revisit and highlight the key principles and developments of…

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…

The question of how the realms of research and practice might successfully relate to one another is a persisting one, and especially so in education. The article takes a fresh look at this issue by using the terminology of collaboration scripts to reflect upon various forms of this relationship. Under this perspective, several approaches towards…

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…

In the heated debate on the gap between educational research and practice, participants often defend single solutions based on monocausal problem analyses. This article aims to improve the quality of the debate by encouraging participants to take a many-sided perspective. To this purpose, we first reviewed the literature and developed an inventory…

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)

Employs a pragmatic philosophical perspective to argue that there is no incompatibility at either the level of practice or that of epistemology between qualitative and quantitative methods of educational research. (FMW)

One reason the field of education research is so vague is that there is no specific methodology that belongs to such research. Policy makers and people who appropriate funds would get a clearer idea of what research can contribute to an understanding of schools, colleges, students, and teachers if the research community were clearer about what it…

Ten articles on the use of multilevel data in educational research are presented. Topics include model specification and building, analytical procedures, aggregation bias, least squares statistics, hierarchical linear models, significance testing, and testing multilevel product-process networks.

Notes the cultural turn in geography toward children's issues. Addresses four research issues: (1) background to current research trends; (2) ethical issues associated with working with children; (3) examples of good methodological practices for working with children; and (4) provocative issues dealing with geographers studying children. (DSK)

In a review of the challenges to progress in providing social research evidence that might usefully inform policy, Oakley (2004) argues strongly that the "paradigm divide" between qualitative and quantitative research communities continues to constitute a major problem. Oakley refers to a number of recent critiques of what is seen as "misplaced…

This paper oriented for new researchers entering the field of CAI research discusses the research experience in this area, outlines some of the important computer requirements of CAI research, and proposes a conservative computer development strategy to meet those requirements. The development of PLATO and TICCIT are described as examples of the…
