Agenda For Researching Teaching (Art): A Visual Model And Research Questions, Nancy L. Leech, Carolyn A. Haug, Ellen Hill Robinson
Nancy Leech
In response to the dearth of research agendas that connect teacher education and teaching in the field and to the call for more programmatic research, the purpose of this paper is to present the Agenda for Researching Teaching (ART). The ART is a visual research agenda that spans the time from a teacher candidate learning to teach to impacting student achievement as a teacher. Furthermore, we include research questions based on the extant literature for researching teachers and teacher education. It is hoped that the model will assist researchers who investigate teachers, teacher education programs, and so forth, to focus …
Do Effect-Size Measures Measure Up?: A Brief Assessment, Anthony J. Onwuegbuzie, Joel R. Levin, Nancy L. Leech
Do Effect-Size Measures Measure Up?: A Brief Assessment, Anthony J. Onwuegbuzie, Joel R. Levin, Nancy L. Leech
Nancy Leech
Because of criticisms leveled at statistical hypothesis testing, some researchers have argued that measures of effect size should replace the significance-testing practice. We contend that although effect-size measures have logical appeal, they are also associated with a number of limitations that may result in problematic interpretations of them in research on children and adults with learning disabilities (LD). The purpose of the present paper is to provide a framework for reporting and interpreting empirical research findings in LD research. Specifically, we recommend that: (1) researchers apply criteria of both statistical significance and substantive significance to help consumers of research assess …
A Proposed Fourth Measure Of Significance: The Role Of Economic Significance In Educational Research, Nancy L. Leech, Anthony J. Onwuegbuzie
A Proposed Fourth Measure Of Significance: The Role Of Economic Significance In Educational Research, Nancy L. Leech, Anthony J. Onwuegbuzie
Nancy Leech
The purpose of this paper is to examine economic significance as a fourth measure of significance. In addition to describing and operationalising the concept of economic significance, a typology of economic significance indices is presented, including an example of how to compute these measures, as well as how to utilise them in applied research. We demonstrate how interventions that yield no statistical, practical or clinical effects may be economically significant. Economic significance is not only relevant in the majority of educational research studies, but also is more readily understood by policy makers and stakeholders than are the other three measures …
