A major obstacle to developing evidenced-based policy is the difficulty of implementing randomized experiments to answer all causal questions of interest. When using a nonexperimental study, it is critical to assess how much the results could be affected by unmeasured confounding. We present a set of graphical and numeric tools to explore the…

This article provides an interpretation of a biblical text about the judge Gideon. It uses the hermeneutic method of research to draw some evaluation patterns from this case study relating to the analysis of needs, the declaration of aims, the context and circumstances of evaluation, the agents involved, the recruitment process, the assessment of…

Background/Context: Two key uses of international assessments of achievement have been (a) comparing country performances for identifying the countries with the best education systems and (2) generating insights about effective policy and practice strategies that are associated with higher learning outcomes. Do country rankings really reflect the…

REL Southwest received a request to review the report "Avoidable Losses: High Stakes Accountability and the Dropout Crisis" to assess the soundness of the study methodology and the appropriateness of the conclusions drawn in the report. The review found that conclusions drawn in this study cannot be generalized and are significantly…

The last significant review of research about transformative learning was in 1998 and was mostly focused on unpublished dissertations. In response, this paper reviews an exhaustive body of research conducted since that time, involving 40 studies, published in peer-review journals with a lens of analysis of new findings and insights on…

Meehl's taxometric method was developed to distinguish categorical and continuous constructs. However, taxometric output can be difficult to interpret because expected results for realistic data conditions and differing procedural implementations have not been derived analytically or studied through rigorous simulations. By applying bootstrap…

Research within a constructivist approach often relies on interview data, which are used to reveal beliefs held by the interviewee or to expose conceptions or conceptual structures that are supposed to reside within the interviewee. From a sociocultural perspective, severe criticism has been leveled against the neglect of the problems of inferring…

In educational research, rigid distinctions between the relative merits of quantitative research often rest on positivistic dogma. In contrast, post-positivistic thought eliminates the intractable problem engendered by positivistic epistemology of a forced choice between value-laden and value-free research methods. (KH)

This paper explores the issues surrounding the study of higher education, usually involving the analysis of structural-functionalism, to less tradition-bound areas representing idealism. It examines these issues through the theoretical framework of symbolic interactionism which, it is noted, rests in the interpretive paradigm. The paper begins…

Introduction: Evidence-based medicine (EBM) integrates published clinical evidence with patient values and clinical expertise, the output of which is informed medical decision making. Key skills for evidence-based practice include acquisition and appraisal of clinical information. Faculty clinicians often lack expertise in these skills and are…

The seven chapters of this special issue explore problems in how to better understand the reasoning process that is used to establish evaluative conclusions. The many unanswered questions about reasoning should stimulate further investigation of the meaning of sound evaluative reasoning. (SLD)

Professional practice is built on sound knowledge specific to each discipline. This knowledge is developed and validated through a process of scientific investigation or research. However, lack of knowledge about the research process acts as a barrier to applying evidence-based practice within the school setting. Understanding the components that…
