This paper presents a content analytic approach on doctoral dissertations in the field of distance education in Turkish Higher Education context from the years of 1986 through 2014. A total of 61 dissertations were examined to explore keywords, academic discipline, research areas, theoretical/conceptual frameworks, research designs, research…

Mathematics education researchers conducting instruction experiments using a design research methodology are challenged with the analysis of often complex and large amounts of qualitative data. In this paper, we present two case studies that show how multimedia analysis software can greatly support video data analysis and theory development in…

The existence, preponderance, and stability of misconceptions related to evolution continue as foci of research in science education. In their 2006 study, Geraedts and Boersma question the existence of stable Lamarckian misconceptions in students, challenging the utility of Conceptual Change theory in addressing any such misconceptions. To support…

Rater biases are of interest to behavior genetic researchers, who often use ratings data as a basis for studying heritability. Inclusion of multiple raters for each sibling pair (M. Bartels, D. I. Boomsma, J. J. Hudziak, T. C. E. M. van Beijsterveldt, & E. J. C. G. van den Oord, 2007) is a promising strategy for controlling bias variance and may…

This study describes a comparison between retrospective questions and daily diaries inquiring about positive and negative support in spousal interactions. The design was a multitrait-multimethod matrix with trait factors of positive and negative support, and method factors of retrospective questions and daily asked questions. Five questions were…

Coefficient Kappa is generally defined in terms of procedures of computation rather than in terms of a population. Here a population definition is proposed. Factors influencing the magnitude of Kappa are identified. Strategies to improve reliability are proposed, including that of combining multiple unreliable diagnoses. (Author/CTM)

This study explores a strategy for improving the stability of variance component estimates when only small samples are available, using a series of small, less complex generalizability (G) study designs as a surrogate for a single large design. (Author/BW)

A review of qualitative methods used in a predominantly quantitative evaluation indicates a variety of roles for such a mixing of methods, including framing and revising research questions, assessing the validity of measures and adaptations to program implementation, and gauging the degree of uncertainty and generalizability of conclusions.…

This paper presents a review of the literature on reliability in qualitative studies. Reliability is defined as the extent to which studies can be replicated, using the same methods, and getting the same results. It is the degree to which data are independent of the accidental circumstances of the research. The review includes the following three…

Factors involved in pre-planned and post-planned evaluation of program effectiveness are compared: (1) reliability and cost of data; (2) internal and external validity; (3) obtrusiveness and threat; (4) goal displacement and program direction. A model to help program administrators decide which approach is more appropriate is presented. (Author/MH)

This paper provides an understanding of the conceptual and operational relationships between evaluation, content analysis, and microcomputers so that evaluation practitioners can better address applied content analysis problems used in their work. The first section presents a general model for conducting an evaluation effort that focuses on…

In order to make policy decisions, educators must evaluate educational research proposals and projects. Findings immediately related to practice are often inadequate, omitting the theoretical establishment of principles by which we can explain and predict the phenomena of our world. These theoretical linkages to the practical world of…
