In this commentary, we offer a set of visual tools that can assist education researchers, especially those in the field of mathematics, in developing cohesiveness from a mixed methods perspective, commencing at a study's research questions and literature review, through its data collection and analysis, and finally to its results. This expounds…

The slope of the z-transformed receiver-operating characteristic (zROC) in recognition memory experiments is usually less than 1, which has long been interpreted to mean that the variance of the target distribution is greater than the variance of the lure distribution. The greater variance of the target distribution could arise because the…

Coburn and Turner (this issue) present an intriguing framework for understanding how data has come to be used in the current high accountability environments in education. In this framework, they connect various processes of data use within organizational and political contexts. Data use is presented using an ecological perspective that deepens…

This poem, with stanzas in limerick form, refers humorously to the many threats to validity posed by problems in research design, including problems of sample selection, data collection, and data analysis. (SLD)

The authors (Ingham et al.) of the original report respond to criticisms by Kalinowski et al. that they misinterpreted their data in a study of the effects of frequency-altered feedback on stuttering in four single-subject design investigations. They also address larger issues concerning altered auditory feedback procedures. (DB)

When gathering and presenting educational statistics, five principles should be considered. (1) The data must be accurate, valid, and complete. Limitations, weaknesses, margins of error, and levels of confidence should be clearly stated. (2) The data must include comparable information, sought in comparable ways, in comparable forms, from…

Three issues must be addressed when discussing the standards needed to judge the methodological rigor of naturalistic approaches to administrative research. The first issue involves defining naturalistic inquiry. In contrast to the scientific paradigm, naturalistic inquiry emphasizes, first, the inseparability of variables or events from their…

Methodological adequacy in naturalistic inquiry is enhanced by understanding the differences between the naturalistic and rationalistic paradigms; by using simultaneous data collection and analysis, with prolonged field research, an audit trail, multiple sources, and referential materials; and by employing "thick description" extensively…

Discusses methodological issues concerning qualitative research and describes research practices that qualitative researchers use to address these methodological issues. Topics discussed include the researcher as interpreter, the emergent nature of qualitative research, understanding the experience of others, trustworthiness in qualitative…

Distinguishes between "research methods" and "research methodology" in social science research, particularly in the field of comparative education. Discusses the influence of the researcher's theoretical orientation on his or her choice of methods for data collection and data analysis, and the importance of scholars outlining this…

The purpose of this paper is threefold: to describe grounded theory research strategies, to present a summary of several studies in education that have followed this approach, and to explore the potential uses of the grounded theory techniques in curriculum theory generation. The paper is arranged into six parts. In the first and second parts of…

This paper is based on the premise that relatively little is known about how to improve validity in qualitative research and less is known about how to estimate validity in studies conducted by others. The purpose of the study was to describe the conceptualization of validity in qualitative inquiry to determine how it was used by the author of a…

Discussion of different types of methodological approaches, and description of the research methods used to study an innovative secondary school in England, make clear why the case study was chosen as the method to employ. The methodological approaches considered included the positivist or scientific method, involving external observation and the…

Describes the method employed for scholarship that involves the analysis of original unpublished scripts. A professional-development grant provided an opportunity to travel to a university archive to read primary research materials unavailable through conventional means, and to develop a detailed analysis of selected works by Ray Bradbury,…

Assesses the value of the Government Printing Office's 1983 "Biennial Survey" as a tool to support depository library planning and decision making. The survey data are evaluated in terms of reliability, validity, and utility, and recommendations are offered for improving the design, administration, and analysis of the survey. (CLB)
