The naturalistic research perspective assumes that reality is multiplistic, phenomenological, and context-dependent. This perspective legitimizes the subjective insights of the investigator by acknowledging the interdependence of facts and values as well as of the investigator and the object of investigation. Although discrepancies between…

Although research on argumentativeness appears to confirm the centuries-old "commonsense knowledge" that successful arguers enjoy arguing and are adept at remaining "cool and rational" during an argument, the empirical research itself is based on normative assumptions that underlie this Cartesian "commonsense…

This paper helps researchers develop criteria for conducting surveys. Cost considerations frame the paper's suggestions. Specifically, the text advises that researchers consider the human and material resources needed, type of survey instrument, medium for conducting the survey (mail, telephone, personal interview, etc.), data analysis…

The terms "rigor" and "relevance" most often surface in discussions of methodological adequacy. Assessing epistemological relevance is equivalent to answering the question, "Is this particular research question worth asking at all?" Epistemological rigor refers to the properties of a "researchable" problem.…

This panel's goal was to improve the validity and utility of measurement, design, and analysis in research on teaching through the stimulation of new methodological knowledge and through the identification and translation of useful existing knowledge from other descriptions. This panel tried to identify as many methodological problems as possible…

Techniques for detecting synergistic effects in analysis of variance designs are presented and discussed. These techniques make it possible to apply some kinds of theoretical insights to the data analysis phase of a study: either by seeking synergistic effects implied or predicted by theory, or by seeking evidence of synergies as alternative…

Researchers have long been aware that "pretest sensitization" is a potential threat to the external validity of experimental studies. Only recently, however, has it been suggested that "posttest sensitization" might also limit the generalizability of results. This latter phenomenon would exist to the extent that the effects of…

The author reviews research which examines a specific aspect of achievement arousal concerning the variable, "self-importance" of immediate activity. It also examines the relationship between "self-importance" and "future-importance"--that is, the extent to which possession of a certain personality attribute is believed necessary for achieving…

The central idea of evidence-based education--that education policy and practice ought to be fashioned based on what is known from rigorous research--offers a compelling way to approach reform efforts. Recent federal trends reflect a growing enthusiasm for such change. Most visibly, the 2002 No Child Left Behind Act requires that…

This paper presents a discussion of various statistical concepts and techniques in light of two propositions. The first is that researchers need to select analytical techniques that prevent them from committing Type VI errors, which are inconsistencies between the research question and the statistical analysis. The second is that many statistical…

This study examined the process followed by graduate students in the formation of research problems for their dissertations. Narratives were solicited from researchers who received Spencer Awards for their dissertation research, and researchers received 30 narratives that described the process of research problem formation. The grounded theory…

Five prototypic issues derived from a dialectical perspective are proposed: relationism, evolving reciprocity, probabilism, timing, and the nonequivalent temporal metric. It is argued that these issues, while not changing the scientific method, have implications for specific procedures. (Author)

Background: Examined or unexamined, all teacher candidates (TCs) bring to their teacher education programs their prior school experience as well as the socio-cultural history of education. This study was one of a series done by this researcher (1994, 2004, 2005, 2006) to find ways to promote reflective practice in teacher education. Purpose: The…

The Welch-James (WJ) and Improved General Approximation (IGA) tests for the within-subjects main and interaction effects in a split-plot repeated measurement design were investigated when least squares estimates and robust estimates based on trimmed means were used. Variables manipulated in the Monte Carlo study included the degree of multivariate…

Repeated measures experimental designs, often referred to as "within-subjects" designs, offer researchers opportunities to study research effects while "controlling" for subjects. These designs offer greater statistical power relative to sample size. However, threats to internal validity such as carryover or practice effects…
