Qualitative research sample size determination has always been a contentious and confusing issue. Studies are often vague when explaining the processes and justifications that have been used to determine sample size and strategy. Some provide no mention of sampling at all, whilst others rely too heavily on the concept of saturation for determining…

A quick review of national policy documents reveals how lifelong learning has evolved as the key principle for a comprehensive education and learning strategy from cradle to grave. This raises major challenges for how to assess and report the state of lifelong learning in UNESCO Member States. It is in this context that this article critically…

Identifying effective literacy interventions for teachers of very young children is important, but it is not easy. In this case study, we share our experiences implementing a quasi-experimental evaluation of an early literacy program. We describe the design and context of the study and discuss three key issues that we encountered with data…

When conducting research on sensitive topics, it is challenging to use new methods of data collection given the apprehensions of Institutional Review Boards (IRBs). This is especially worrying because sensitive topics of research often require novel approaches. In this article a brief personal history of navigating the IRB process for conducting…

The Council of Australian Governments (COAG) has endorsed a "Closing the Gap" agenda designed to improve the lives of Indigenous Australians. The agenda is distilled in a series of targets, one of which is the goal of halving the gap for Indigenous students in Year 12 attainment or equivalent (Certificate II or above) attainment rates by…

Age is often ranked as a significant variable in research studies concerned with the measurement of intellectual and linguistic capacities, including reading. In fact, age is often cited as the cause of a decline in performance on such tasks. However, determining the social, psycho-social, and physiological status of subjects and applying…

The use of fieldwork in evaluation presents the fieldworker and agencies connected with educational evaluation with a number of critical problems. Four of these problems are identified and discussed: 1) definition of the "problem"; 2) multiplicity of signals, expectations, and responses; 3) dispensation of fieldwork data; and 4) collection of data…

Two methods for dividing an interrupted time-series study between baseline and experimental phases when study resources are limited are compared. In fixed designs, the baseline duration is predetermined. In flexible designs the baseline duration is contingent on remaining resources and the match of results to prior expectations of the evaluator.…

The methodological and practical problems that are especially common in or unique to assessment research in correctional settings are discussed. The distinctive culture of correctional institutions and the complications caused by governing bodies contribute to the particular problems encountered in collecting and analyzing data. (SLD)

Problems that face evaluators, including field based evaluations, are discussed. The author states that open communication, access to data, and an ability to be accepted are paramount; knowledge of randomness, robustness and homoscedasticity may be secondary. (Author/PN)

Many evaluation researchers are now attempting to synthesize quantitative and qualitative approaches. Although such efforts appear to carry great promise, some subtleties and incompatibilities of these approaches are perhaps being overlooked. Implications for social inquiry are discussed. (Author/GDC)

How social science theory and insight could be applied to understanding and resolving the issues surrounding misconduct in scientific research is discussed. Understanding why scientists break the norms of acceptable conduct may come when their survey responses are interpreted in the contexts of sociology and psychology. (SLD)

Global economic transformations have never been as dramatic as in the twentieth century. Most countries have experienced radical changes in the standards of income per capita, technology, fertility, mortality, income inequality and the extent of democracy in the course of the past century. It is the goal of many disciplines--economics, history,…

Possible bias due to sampling problems or low response rates has been a troubling "nuisance" variable in empirical research since seminal and classical studies were done on these problems at the beginning of this century. Recent research suggests that: (1) earlier views of the alleged bias problem were misleading; (2) under a variety of fairly…

This paper acknowledges that research on school dropouts presents problems in the definitions and computation of dropout indices. It considers a variety of methods for computing dropout rates, using dropout rates which are real and which were available at the end of the 1986-1987 school year. Fall enrollment, average daily membership, and total…
