Although generalization from training to practice is one of the most important goals of education, generalization oftentimes does not occur spontaneously and deliberate planning is necessary. One way to enhance generalization to real-world settings is to build in similarities between training and test situations by including video in training.…

When two or more univariate population means are compared, the proportion of variation in the dependent variable accounted for by population group membership is eta-squared. This effect size can be generalized by using multivariate measures of association, based on the multivariate analysis of variance (MANOVA) statistics, to establish whether…

Because the power properties of traditional repeated measures and hierarchical multivariate linear models have not been clearly determined in the balanced design for longitudinal studies in the literature, the authors present a power comparison study of traditional repeated measures and hierarchical multivariate linear models under 3…

This study considers the problem of testing the difference between treatment and control groups on m [greater than or equal to] 2 measures when it is assumed a priori that the treatment group will perform better than the control group on all measures. Two procedures are investigated that do not rest on the assumptions of covariance homogeneity or…

Multi-ball collisions inside the Astroblaster toy are explained from the conservation of momentum point of view. The important role of the coefficient of restitution is demonstrated in ideal and real cases. Real experimental results with the simple toy can be compared with a computer model represented by an interactive Java applet. (Contains 1…

Reliability generalization studies have provided estimates of the mean reliability coefficients and examined factors that explain the variability in the reliability estimates across studies for many different tests and measures. Different authors have used different data analyses to do such meta-analyses, and little research has addressed whether…

This article presents excerpts from a case study describing Angelica Dawson, a New York State music educator. Angelica makes improvisation a central part of her curricula in ways that transcend traditional offerings prevalent in American public schools. Qualitative research methods were used to document Angelica's work over the course of an…

Whether Willingness to Communicate (WTC) is a permanent trait or is modified by situational context has previously been investigated in various studies (e.g. Cao & Philp, 2006; Kang, 2005; MacIntyre & Legatto, 2011). However, most research into WTC has been quantitative or conducted in the English as a Foreign Language (EFL) or Study…

This paper reports research that investigated parental support for children's reading of English in an inner-city school in the developing country context of an Indian city, Ahmedabad. Children had oral proficiency in the regional language but were beginning to acquire conventional forms of literacy in English. Sociocultural mediation theory…

The effects of bilingual education on reading and math achievement were examined by comparing test scores across different elementary school programs. Results revealed that bilingual Two-Way Immersion (TWI) programs benefited both minority-language and majority-language students. Minority-language students in TWI programs outperformed their peers…

Research on the adaptation of children of migrants in Russia shows that while they adapt successfully in many ways, there is a need for teachers to be better equipped to deal with the cultural conflicts these children often experience.

The authors report on an exploratory pilot project implemented in a large city on the U.S.-Mexico border. The project focuses on a curricular design in a secondary school where beginning-level English as a second language students are taught English language arts in Spanish. The researchers sought to determine whether these students made greater…

This study compares the pedagogical practices of African American Sunday school teachers and their secondary English/Language Arts pedagogical practices. The major purpose of this study is to determine if there is a connection between African American Sunday school teachers' pedagogical practices and their pedagogical practices within the…

The PIRLS 2011 international database includes data for all questionnaires administered as part of the PIRLS 2011 assessment. This supplement contains the international version of the PIRLS 2011 background questionnaires and curriculum questionnaires in the following 5 sections: (1) Student Questionnaire; (2) Home Questionnaire (Learning to Read…

Early math skills are the strongest predictors of later math achievement in school. This two-wave study addressed three research questions about the role of families in fostering these skills in preschool-aged children. First, how do families talk about math at home? Second, how do these conversations vary across families with different…
