The "World Report on Children and Violence", (Pinheiro, 2006) was produced at the request of the UN Secretary General and the UN General Assembly. This report recommended improvement in research on child abuse. ISPCAN representatives took this charge and developed 3 new instruments. We describe this background and introduce three new measures…

This study examines the geopolitical agency of Palestinian children. Mixed methodology was used to identify the etiologies contributing to processes of political socialization. Both qualitative and qualitative methods are equally distributed throughout this research. Focus groups and interviews with 12 Palestinian children, aged 10 to 13 years,…

The effect of stratified sampling of items on the estimation of test score distribution parameters by multiple matrix sampling was studied. Item difficulty and/or interitem correlations were the bases of stratification. Various item iniverses were created by computer simulation and sampled according to several plans. The results indicate that…

This paper presents a procedure called multiple matrix sampling which simplifies data collection for drug incidence surveys. Advantages for the use of multiple matrix sampling with drug surveys are discussed and a practical example is outlined presenting the guidelines for a sampling plan. (Author)

Introduction: Tutorial-based assessment, despite providing a good match with the philosophy adopted by educational programmes that emphasize small group learning, remains one of the greatest challenges for educators working in this context. The current study was performed in an attempt to assess the psychometric characteristics of tutorial-based…

This paper explores the implications of looking at creativity in terms of repeated sameness rather than observable difference. Drawing on insights from hip-hop culture that focus on sampling as creativity, and looking in particular at philosophies of difference that make iterability and performativity central, this paper opens up a discussion of…

This research is an interpretive qualitative study that explores the perceptions and perspectives of two generations of African American male students, as related to their educational experiences at the same southeastern New Mexico high school. The central question of this research is, has the educational experience for African American male…

Student performance on critical-thinking applications on standardized tests in a southwestern U.S. state has been low for several years. The purpose of this instrumental case study was to explore how one school district prepared students for critical-thinking applications on standardized tests. The study was informed by cognitivism and…

In large-scale assessments, such as state-wide testing programs, national sample-based assessments, and international comparative studies, there are many steps involved in the measurement and reporting of student achievement. There are always sources of inaccuracies in each of the steps. It is of interest to identify the source and magnitude of…

The choice of design parameters (e.g., number of subtests, number of items per subtest, and number of examinees per subtest) can be controlled by the test constructor in a multiple matrix sampling evaluation. The purpose of this study was to determine empirically which combination of the above parameters produces the smallest standard errors of…

In many situations in education and psychology it is desired to select from k binomial populations the one having the largest probability of success. This paper describes a two-stage procedure for accomplishing this goal. (Author/CTM)

When analyzing a squared multiple correlation coefficient, an investigator may be interested in determining whether it is above or below a known constant, rather than testing the null hypothesis. This paper gives the sample sizes required for answering this question when indifference zone formulation of the problem is used. (Author/BW)

The Statistical Analysis System was used to program a statistical procedure developed by K. J. Levy (1975). The focus was on Dunnett-like pairwise multiple comparisons among sample variances. An example using data from G. Glass and K. Hopkins (1996) is used to illustrate a computer run with this program. (Author/SLD)

Focuses on meta-analysis in educational research. Contends that, if significant meta-analysis results are overrepresented through selective sampling, hucksterism in form of sampling bias exists. Explains use of follow-up test, the fail-safe N. Includes tables constructed to assist researchers and practitioners to estimate, without calculation,…

Standard Microsoft Excel functions and the Excel Data Table facility are used in randomization applications using resampling with and without replacement.
