This paper discusses the problem of maintaining confidentiality in data resulting from research projects. The rights and responsibilities of the parties involved in a research effort are examined. Five parties to a research project are identified as: (1) the participants, often called subjects, who have the right to privacy and the responsibility…

From a priori and post hoc data collection perspectives, this paper describes the interrelations among (1) power, alpha, effect size, and sample size for hypothesis testing; and (2) precision, confidence, and sample size for interval estimation. Implications for special education researchers working with convenient samples of fixed size are…

Although successful dropout assistance programs depend on effective implementation, casework, and long-term followup activities, the literature only occasionally addresses these practices. This article reviews data collection problems, major risk factors, reforms aimed at actual and potential dropouts, and alternative school programs. Second…

The procedures used in a successful mailed evaluation questionnaire effort are described, and guidance is given to those who are unfamiliar with the methodology. (Author)

Based on the premise that Canada needs to collect, collate, analyze, and disseminate reliable data on early childhood education and care (ECEC) programs that are comparable across provinces/territories and that good data are fundamental for informing policy, research, and service delivery, the National Data Project was funded in 2000-2001 to…

During round 16 of the National Longitudinal Survey of Youth (NLSY), 900 NLSY sample members were randomly assigned to be interviewed about the period since their round 14 interview. Their responses were compared to those of approximately 8,000 NLSY sample members who were assigned to be interviewed about the 1-year period since their round 15…

Meta-analysis of Title I program evaluations shows the norm-referenced model overestimates positive effectiveness; while the regression-discontinuity design underestimates it. Potential biases include residual regression artifacts, attrition and time-of-testing problems in the norm-referenced design, and assignment, measurement, and data…

Investigates the myth of the inner-city elderly as isolated. Suggests: there are severe limitations to traditional measures of determining sociability; social network analysis can overcome many of the deficiencies of other methods; and a synthesis of the anthropological and sociological approaches to network analysis can optimize data collection.…

Discusses problems of classifying racial and ethnic groups when collecting statistical data. Argues that surveys must acknowledge the great diversity of the American population and give respondents the freedom to choose the group or groups to which they belong. (FMW)

Follows the development of the conceptual boundaries used in defining a case study through the stages of a research project about the development of teacher knowledge. Compares the process with the Hermeneutical Circle. (FMW)

Describes the experiences of Cabrillo College (California) in constructing a personal computer-based student tracking system. Addresses data collection and such obstacles as access to the mainframe, limited/erroneous/inconsistent data, lack of information on within-semester persistence, and understated graduation rates. Reviews benefits. (DMM)

Trends in European practice that relate to qualitative assessment in the evaluation of the impact of research and innovation are discussed and analyzed. To date, European evaluations have been mainly concerned with quality and direct impact with few assessments of medium- or long-term impact. (SLD)

Explored applicability of the Loevinger conception of ego development for early adolescence and developed a measure of earliest ego levels: Sentence Completion Test for Children and Youth. Found oral administration of test did not yield essentially different responses or significantly differing ego-level scores from the written version, regardless…

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,…

Given the complexity of classroom reading observations, maintenance of measurement reliability is a concern to researchers. Sources of variation contributing to the unreliability of many measurements may be either (1) lasting and specific, (2) lasting and general, (3) temporary and specific, or (4) temporary and general. Lasting-specific sources…
