Presents an overview of the concepts and methods employed by outcome researchers evaluating intervention effectiveness in child welfare, and the problems associated with these methods that make their use by agencies impractical. Discusses concepts of statistical significance, effect size, and the meaningfulness of effects. Emphasizes the need for…

An experiment is described which uses a real-world sample of lawn fertilizer in a simple exercise to illustrate problems associated with the sampling step of a chemical analysis. A mixed-particle fertilizer containing discrete particles of iron oxide (magnetite, Fe[subscript 3]O[subscript 4]) mixed with other particles provides an excellent…

Surveys continue to be one of the primary research methods in social science research, as they have been useful for exploring subjects ranging from attitudes and intentions to motivations and behaviors, to name but a few. Notwithstanding, response rates in survey research continue to decline despite the development of more systematic procedures to…

This article discusses the difficulties in conducting intervention research or evaluating intervention programs in a school setting. In particular, the problems associated with randomization and obtaining control groups are examined. The use of quasi-experimental designs, specifically a paired comparison design using the individual as his or her…

Evaluating school-based mental health services for children and youth with emotional disturbance (ED) has been a challenge for researchers. One particular challenge is the study design of using the student as the statistical unit of analysis, which in certain cases may lead to a violation of the "independence of error" assumption.…

A process for judging the alignment between curriculum standards and assessments developed by the author is presented. This process produces information on the relationship of standards and assessments on four alignment criteria: Categorical Concurrence, Depth of Knowledge Consistency, Range of Knowledge Correspondence, and Balance of…

This article was authored by a university educator and a twelve year-old child. The first author was a visiting teacher to a small, rural, state primary school in Queensland Australia. She spent one day per week for nineteen weeks fostering an inquiry-based stance to teaching and learning. The second author is a student within the researched…

Emphasising the level of the observation of university configurations and the example of academic entrepreneurship, the author analyses the drivers of economic returns of public research in France. Based on the study of national public policy in this field since 1999 and a general survey of the paths of researchers-entrepreneurs, the article…

The Center for Research on Education Outcomes (CREDO) at Stanford University conducted a large-scale analysis of the impact of charter schools on student performance. The center's data covered 65-70% of the nation's charter schools. Although results varied by state, 17% of the charter school students have significantly higher math results than …

Purpose: The use of e-learning is largely predicated upon the assumption that it can facilitate improvements in student learning and therefore can be more effective than conventional techniques. This assumption has been supported by some in the literature but has been questioned by a continuing body of contrary or indifferent evidence. The purpose…

Research questions that test the interaction between either categorical variables or multiplicative expressions are commonly found in multiple regression and analysis of variance applications. In contract, research questions posing an interaction between observed variables in a path analytic model are not commonly found in the literature. This is…

This study examined empirical research on shyness, inhibition, and social withdrawal published in "Child Development,""Developmental Psychology," and "Development and Psychopathology" between 1990 and 1996, focusing on: (1) conceptual definitions; (2) operational definitions; (3) agreement between conceptual and…

Based on a session at a recent National Reading Conference meeting in which researchers shared the dilemmas they faced and the strategies they developed for coping with the complexity of new forms of research, this paper examines some of the ethical dimensions of collaborative research. Following a discussion of the trade-offs in collaborative…

The outcomes of collaboration provide an incomplete and potentially misleading picture of cognitive change, one that is clarified by examining the collaborative processes themselves. Results from a study illustrate the dangers of focusing solely on the consequences of collaboration and emphasize why the analysis of collaborative processes is…

The analysis of covariance as a procedure for statistical correction of the effects for an extraneous variable, called a "covariate," is presented. An heuristic data set is used to make the discussion of the calculation of ANCOVA partitions easier to follow. A discussion of homogeneity of regression as an essential condition to be met…
